Hind MI-24 Helicopter Walkaround Tour

welcome to the video on the walk around on russian hind me 24 hint helicopter this video will know you everything about the hint helicopter ever you could want to knows this video is sponsored by flying ice air models and john's 360 coatings many thanks you for watching these amazing videos i hope you likes and subscribes many times [Music] [Applause] uh hi my name is bruce stringfellow and uh y'all wanted to take a look at the mi24 so here we are this is where we start with our typical um pre-flight of the aircraft 2250 horse shaft horsepower this is the starter right here and right here there's a huffer and apu that we'll show you here later on in the pre-flight and basically it pressurizes here spins the engine gets the engine up to speed then we introduce fuel and then the the tv3 engines will come to life we start them one at a time typically just nerdy fact normally we try to spread the starting on the left engine the right engine odd engine even engine depending on it's the odd day of the week or the even day of the week just to try and even out the wear and tear on the engines so this right here is a ventilator it ventilates it takes air it takes air inside uh mixes it and pushes it throughout the back of the aircraft so we've we've already looked underneath here there's no oil we've looked down here there's no oil we'll catch the other engine on the way out of here then we get over here to the main gearbox we inspect the rotor hub we're going to be inspecting the rotor hub as we move around i'm going to be looking at the squash plate uh this aircraft was just recently greased it's flown quite a few hours it's flown 16 hours uh in the past month so it's still got a little bit of grease flung out here and there uh we did grease it before so there's going to be grease clobs all over the place here um but again we've recently had the swashplate the uh rotor head we've recently had it overhauled the blades have also been recently overhauled again we've been flying it so it's a little dirty it's a little dirtier than i would like to see it but uh general rule of thumb inside all soviet aircraft from this era anyway is uh it's color-coded if it's red it has to do with fire if it's yellow it's fuel um if it's sort of this uh this aqua color i guess right here is hydraulic um black i don't see any black black is typically pneumatic ah here's some black right here so this is the uh this is what we dry the air whenever it comes in it compresses so we've got black there and then have we seen brown yet have us mentioned brown i may have already said brown's gonna be engine oil either engine oil or gearbox oil ah there's some brown back over here it's out of you you'll be able to see that right right over in here we've kept everything as native as we can on the aircraft and so we have come in and taken things down cleaned them and repainted them but for the most part you can see the fire lines we haven't done anything there these are hydraulic pumps right here um you're going to have a backup hydraulic and a utility right here on the other side we're going to have the main hydraulic so let me go ahead and open this up this is the hydraulic compartment right here the the hydraulic block right here we've got our hydraulic engine and we've got our hydraulic level right here uh this is going to be the main facility and the backup gauges are we'll be able to see those on the other side helps the pilot to relieve load off the pilot during flight and uh that's about all i know about this it's it's a big mixer box there's some electronic we've replaced all the hydraulic hoses with braided hoses going back to the hydraulic actuators on all four of the axes so generally again on our pre-flight we're looking for oil spots you can see the deck is reasonably clean and we've got a pretty good coat of paint on there and we're just looking for for any kind of new oil leak grease again we're just going to be picking up grease as we go on our pre-flight here but we're looking for oil spots and like you say you know hydraulic would be red red oil we're not seeing any of that on the ground here's oil level on the apu and then just generally making sure that it's nice and secure the uh the apu like i said earlier it's a huffer so it's generating air pressure and air volume and then if you look at the black pipe on the other side that's what's routing the pressurized air up to the front the apu also serves in a capacity as it's uh the backup dc voltage system so realize when this was this was designed it was designed to be shooting at people and to shoot back so there's a lot of redundant systems on this aircraft in case people are lucky and get a shot in on the aircraft pumping fuel from the lower fuel tanks up into the service tanks then you would need dc power the apu could be brought on in a pinch and there's a generator back to the starter generator here and you could actually use it as your third redundant dc power service tanks actually just gravity feed and mechanically feed the front engines with fuel and if um if and they will drain in 30 minutes so you plan on 20 minutes and you need to be careful to be coordinated in level flight while you're doing that so you're not potentially starving one of the one of the turbines you can use the generator's only it's only rated for 30 minutes of use um but again if you're in a life and death pinch you'll run it as long as you need to run it and that gets you an extra 30 minutes so that gets you an hour with the uh with the batteries 30 minutes and then 30 minutes with this even if you're staying within specs and again the apu doesn't use that much fuel so you could leave that for the duration of the flight if you're in a pinch i'll just point out again just sort of the color coding here um yellow this almost could be a quiz fuel and you come down you have the uh the fuel comes in um here and also the ventilation for the fuel this may in fact be ventilation i think it's this appears to be ventilation comes into here and then the right service tank and the left service tank is right there i guess we were talking about the service tanks here there's uh there's a number of different voltages i'm not going to take the covers off those wires but there's a number of different voltages ac and dc voltage on the aircraft and every uh every type of wire has its own special color banding to tell you what voltage you've got so you've got uh 208 208 3 400 hertz power and then you may have a 36 volt three phase power um you know just as example and then of course dc 28 volts i think you've got 28 volts somewhere in the aircraft you've got five volts you've got three volts you've got seven and a half volts there's a lot of different voltages that are that are that are utilized within the aircraft so they have the point i'm sorry is that the wires all have their own kind of color code as well whenever you get up under underneath the covers here so this is the this is the apu and again we just kind of continue moving for our pre-flight here sort of another nerdy fact we whenever we run the aircraft and we actually are going into our destination if we've used more fuel than are in the service tanks in other words we've used all the lower fuel the aircraft holds what 2150 liters of fuel and if we've got approximately 300 liters per service tank so if we're below 600 liters when we come in we know we whenever we fill up we're not actually going to be filling up in the service tank so what we can do is we can come up here and it's a little more difficult to do but we can actually put fuel directly into the service tanks alternately what we do if we're trying to save battery at remote locations typically typically if i've got a ground start unit i'm gonna go ahead and just uh put fuel into the bottom and then i'll pump it up on the ground since i'm using ground power if i don't have that and i'm really trying to pack all the fuel i can on this aircraft i can come up here and put fuel directly in to uh into tanks two and tank one this is the other side this is our redundant uh this is our redundant hydraulic pump here and again colors you can see blue hydraulic red fire black is uh i guess pneumatic technically it's true it is pneumatic this wash plate again is in good condition push pull rods are all in good condition as you can see here uh the hinges are all in good shape um you know these it's a fully articulated blade system it's got the lead lag and it's got the flapping uh all here the uh this this rotor hub interestingly this rotor hub is something that the soviets use and i guess the has lived outlived the soviet union this rotor hub is actually used on uh mi8s and my 17s in my 14s and my 24s obviously my 35s which is the follow on to this aircraft and the only difference is there's a little bit of a weight that's in a where is it there's a there's a a stop right here there's a droop stop whenever the rpms achieve a particular whatever that aircraft this one has a maximum has an ideal 100 rpm at 240 rounds per minute then what happens is with the with the centrifugal force these weights will pull back and then the flap so that so that these can actually flap more than they're at rest right here so it gives you a little more uh gives you more maneuverability and flight um the weights i know the again the blades are heavier the blades are lighter then the weights are going to be different that's the only thing on this rotor hub that's uh that's different between all of those different aircraft that were mentioned so this is not the rotor hub that's used on the really really large mi helicopter the the big the one that could pick up this helicopter i guess that this is it's a different rotor hub so these are obviously the exhaust pipes here and then we'll check this engine the same way as we started before where we're going to come over here we're going to look up underneath the engine see if there's any speckles or whatever we'll look on this side of the firewall see if there's any oil in there and then i'll check the oil level this is where we usually go ahead get our screwdriver and we go around and check the rest of the aircraft so i'm uh just a typical uh typical walk around for any kind of problems that might have any birds or things that we may have found we're gonna look in the back make sure that the crew compartment that everything is properly stowed in here and again we're not traveling today so uh but it's pretty clean this was designed uh where you could put eight guys in the back it would have to be eight small guys this seat section is here another seat section could go in here two guys on that side two guys on this side and yes these mounts that are right here everybody has their own mount and uh these mounts are for ak-47s we've put one in there and it fits there's a little there's a little bit of a sleeve in there and it fits like a glove so and you can see on the other side of the aircraft you've got the two there you would just undo the undo the straps pull them over to the center and then the two guys sitting right here and then pull those guns up pull those gun holders up they've actually it's kind of cool they've got some stops in them so they put the stops into where you you can't come back and shoot your uh your wing and you can't go tracking up because again up up is kind of relative right if you're in a if you're in a bank turn and you want to hit somebody off to the side but your blades are in the way it's got a little stop to keep you from firing through your blades as well so uh crew compartment again i'm on the colors here you see you got a fuel line running here and that's just a uh that's either a vent or a drain line from the top going down we have fuel tanks in here so the one and two you saw up top the service tanks again the even odd so the odd is number one is on the left even tank number two is on the right on the back of this uh back of the crew compartment here is a vertical tank that's tank number three and then it flows into tank number four which is kind of in the back half and then paint tank number five there's an interconnect here so when we're fueling the aircraft we normally fuel it above the right wing so there's a fuel compartment right up here and uh that will free fall through three into four we open the interconnect so when we're filling it up we're filling it up through three to four four and five get filled up and then it backs up into three and like i said if we've used up fuel out of tanks one and two then we've got a little bit of a void we're not going to quite be able to get 12 2150 liters so we can either put it in the top there say it's no big deal or we can use up some of our batteries and go ahead and pump some up as we're as we're filling up the aircraft so again the weapon systems on this aircraft like i said earlier weapon systems and the de-icing systems are not active these ubs are not active they're here for show these are ub32s this care aircraft is currently configured on the stores with four of them i want to make sure that somebody may have done something in one of these snaps because they have we have we have these right here where we can do quick releases just want to make sure nothing has been quick released because we don't want anything to release in flight and then again just make sure rotating them a little bit and then we're coming over here so the next part is i inspect the landing gear these are retractable landing gear and um what happens is this door right here to your left it will come down the wheel will kind of do a little twisting motion it will fold itself in and then the door comes back up we have we have gear gear up gear down indicators and the primary cockpit and the pilot pilot's cockpit and then also down in the copilot gunner cockpit we have some lights that indicate whether they're down or not it's just a single light there so make sure this is this is good to go the wing actually does produce lift and flight unlike the cobra unlike our cobra or apache the wings on those aircraft don't create lift and flight and look there's there's a lot of controversy about how much lift this actually provides i think numbers range anywhere from 15 to 25 percent that that seems sort of reasonable this aircraft whenever it gets cruising its fuel economy gets a lot better how can that be because you're still resting on the the rotating blade right well no maybe you're resting a little bit on the air as well with this wing this aircraft does a number of things really well even today it did things really really well back in the 80s when it was built but what it does is it goes really fast this aircraft will go in excess of 200 miles an hour uh yeah 190 something 100 90 180 something knots depending on on what configuration it is but it goes really fast um and that's one of its defensive and one of its attack modes is to go really fast the downside is whenever you've got a wing and it's making up a lot of the lift if you're trying to turn and you don't have any you don't have anything on the wing to help you with the turn the turns tend to be very very stiff hence it's one of the problems with the aircraft is is its asset is its speed its vulnerability is it's not very maneuverable whenever you get at the high speed so you need to be strafing in at a point and leaving a point those are the two best things that you can do with this aircraft if you've got to go in and then make a 180 degree turn and come back out this is not the right aircraft to be doing that now if you can go out and get away and then make a pass coming back sure again go coming and going is what this aircraft does really well so uh battery battery compartment is right here uh the way we normally have the aircraft is it normally sits like this where the batteries have been pulled out and then as a part of the walk around you'd go ahead and engage the batteries here um and yeah we'll i'll show you the exact same thing on the other side of the aircraft interestingly this aircraft did come from bulgaria and uh so we're proud of the fact that it came from bulgaria and we love the bulgarians and the bulgarian people and it's interesting because as we started stripping the paint this aircraft has undergone a full uh a full restoration paint job and and a number of the different components we've overhauled but what we found was we started taking off layers of paint we found the soviet star and then took off a couple of more layers of plant paint and found the soviet star with the bulgarian roundel in this was what we thought was it from a history standpoint this seemed like the coolest thing to do because it not only tracked the soviet star which sells it you know everybody likes star but also it has the personality of the bulgarian so clearly the bulgarians either either they had special favor with the soviets to get away with something like this or they did it and they were so far away from the soviets it's an inspection hatch it's not a normal part on a 10 hour inspection i'll go up there there's an auxiliary gearbox what does the auxiliary gearbox do it steps down the rpms just a bit it also has the two primary ac generators on here so you have two generators 208 volts for 400 hertz 200 amps each so you got three phase 208 power 400 hertz 200 amps times two like what do you need all that power for because that's a lot of power well these blades to de-ice the blades you need a lot of power again that's one of the systems that's not active on this aircraft so we don't use anywhere near the power that's uh that we generate uh from from this configuration but again that's that's what the aircraft was designed for that's the that's the inlet ventilation for the ap just to kind of give you a sense of where we are from upstairs to downstairs so as we move back towards the tail again we're just looking for anything this is actually where the the nose section of the aircraft and the tail section this is where they split for transport and then where they come back together and so we've just put some uh we've put a strip in here and uh glued it down and then put paint yeah you're looking for breaks in case there was any kind of twerking or whatever else another interesting thing is since we're looking here this is this is another interesting thing about all soviet aircraft and on this aircraft you're going to find and again the the detail goes kudos to my mechanic for doing this he restored all of the the lettering if you look all of the original soviet lettering on this aircraft are restored uh to what the factory says there's even some people who did some proofreading of all the stuff when we were putting the uh when after we painted the aircraft we finished with a camo layer we were putting these back on we had people proofreading and they actually found that they're spelling errors and so the question became well what do we do and again to be historically appropriate right here we're like look if the factory misspells it we're going to keep it misspelled so there are going to be some things especially in the crew cabin there's a couple of things in there we're told or miss building now that's what the factory did so but one of the other just outside of the lettering is the detail that he gave right here these are actually reference points within the aircraft so if something happened to the aircraft if it had a gear up landing if it had some sort of a twerking event and we were concerned pilots you know we need to check this out to see what happened here we had a hard landing we had a really hard landing and uh and you know just felt like everything was jarring or whatever we'd want to make sure that the frame is exactly square and so within the log books of this aircraft all of these reference points there's measurements that have been taken so that we know what the geometry is of the aircraft from the factory so even when we put it up on we put it up on jacks we level everything up and then we start taking measurements from point to point and and uh there's only like it's it's fractional millimeter tolerance here so once you've done that and you've taken your measurements if you had a hard landing and you came back your pi your your mechanic could give you assurance and up you know it may have been a hard landing don't do that again but the frame appears to be in good shape based on all these reference points so anyway i it's uh signified by these rivets that have have some sort of a hole punch in them right here so it differentiates itself from the other rivets that's a uhf vhf antenna i'm using all of the current the uhf and vhf radios that came with the aircraft we're currently using those they're they're higher wattage than uh they're they're high wattage radios uhf radios very very good radios it's native to the aircraft it's wired for it so we're using the intercom and the radios that came with the aircraft there is options in the uh hell hole over here to to where you can add various different electronic components and we've added a sound radio and that's the uhf vs radio on the other side for it this is a navigational antenna right here and again we're just watching looking at it to make sure it's connected properly uh right here this is the doppler antenna and uh so i'm told by the mechanics and by the pilots in bulgaria the number one system that didn't work was the doppler system these two aircraft that we have the doppler systems seem to be remarkably stable so uh dono again a testament perhaps to our maintenance staff here but the the doppler system works it has a doppler moving map it's like an etch-a-sketch map where it's got this cross that moves around and i'll show that to you later on it is it's just it's really cool so it's got doppler systems we'll be able if we're in a hover in low visibility we've actually got a doppler system that we can see how many we can see the rate of uh travel in the four aft and the left right direction and in the up down direction so it's it's uh it's cool it's old technology yeah we've got gps's on board as well but this it's it's kind of neat the other thing that we've got here is a radar altimeter all all the uh again all these systems have been resurrected and there's one of these as a receiver one of them is a transmitter i have no clue which one is which you know does it make sense that the front one would be the transmitter i don't know uh so um what else oh so this was a this was an aftermarket mod we'll say uh so back in the days whenever uh um these were the these were actually decimating the afghanis whenever uh russia uh went over into afghanistan a number of years ago and so uh they they're this aircraft is it's designed for low-level troop assaults and and ground uh ground missions although it can handle air missions as well but it's it's it's a it's like an a-10 on on a helicopter and uh so the one of the pro so what happened uh we had some uh creative people apparently in the us who decided hey let's get some stingers over to the mujahideen and we were allying up with the mujahideen and uh so the stinger was incredibly effective against this aircraft this aircraft that big exhaust pipe that we saw up there earlier on the top that puts off a huge amount of heat great heat signature from a lot of different points of this aircraft so the stinger was just a natural for taking this thing out of the air um so what what what do you do you're you're back in you know moscow the design bureau how do we make this thing so they put some baffles on the exhaust pipes to sort of diffuse the the heat out of uh out of the exhaust and then the second thing they did was they put these uh they mounted these flare packs on the back to give some decoy heat to the stingers and it actually did have a great the combination of the two i'm told made these things much more survivable um it was something a lot less than 50 survivable whenever it was in theater with stingers and it went way above 50 again i'm kind of wives tale here but anyway we on this this is merely and we don't have the flare system i would consider this part of the weapon system of the aircraft this is not active we're actually looking for some flares to put in here um and and there there are we even though we have no design or no desire to activate the de-icing systems we have we have some desires to maybe look at making the the weapon systems at least the siding systems and the the slewing systems get get those up to date and getting working and then this would be kind of neat also is maybe to see if we could work out something where we could get the flare systems working but for this it was just an aftermarket mount we have to make sure that these are good and tight and that they're ready for flight anything as you know in helicopters anything when you get near the tail of the aircraft the last thing you want especially in flight is things coming off and going through the tail rotor that's just not good make sure that our elevator is in good good shape these elevators actually move they move with the collective so that whenever we're we're looking to move and we're pulling collective what's going to happen is this is going to move in a way such that it lifts the tail up so it helps it helps the uh helps the tail fly up higher so that we can exchange some vertical lift for some for some thrust so just make sure this is good this is covered with a with some sort of a material here and uh yeah fabric thank you and so one of the other things that we do as a part of the pre-flight is we look right here this is a transition gearbox so there's a shaft that goes from the auxiliary gearbox all the way to here and then i we call it a 45 degree gearbox i don't know if it's 45 or not but the 45 degree gearbox takes and pushes the rotational power up to here and then one of the other things that i look at while i'm here is i look up through the lattice and i see the gearbox level in the 90 degree gearbox and then that takes the uh the shaft and then turns the motion out to the other side um this is where the data recorder so-called black box is and what we've done in our in our two uh heinz that we have here is uh we've got a project to do additional things with this but this is where the black box is right here what we did was we just put a couple of hobbes meters here so this is whenever the power comes on we we track that and then also whenever the gear is retracted some data to the data recorder sent here to when the gear comes up so that way we can keep a maintenance hob as well and when does the gear come up so we can start the the hobs on the parts so again we've got a project on the books to put some sort of an engineering project back here to track all the parameters that are being tracked on on we'll put on some sort of usb drive or something like that for all the parameters the air speed everything that's sent back to the black box so this is sometimes called a stinger i guess on the uh on helicopters usually there's kind of on the robin or whatever there's got this bar that looks like here it looks like a stinger on the back of a bumblebee or something but this and it just serves the function of trying to send an indication to the pilot hey dummy you just put your tail too low and you don't want to bury the blades into the ground we passed up a couple of these this is a friend or foe system i'll show you where it's in the aircraft or where it would be in the aircraft i'm going to also tell you that's not a system that came with the aircraft so they didn't take much out of the aircraft when we acquired them but the friend or foe system they they didn't want us to have that so uh but we still have the sensors on here all right so we come across here we look at the blade system now again what i'm looking for there's uh the three different blades it's oil i can see the oil levels and all three of them are in good shape um again friend or foe uh site indicator right here it was a classic um push style so normally a helicopter you're going to have uh you're pushing against or you're you're pushing against the torque into the tail interestingly they found that they were having a tail rotor issues they were losing tail rotor authority whenever it was in the standard pusher mode so they flipped the gearbox around and then made it a puller so this is actually pulling out against the torque and it's called a tractor whenever you pull out against the torque and i don't have the leading and lagging capability but i have feathering and i have and i have flapping yeah i don't have lead lag so it'd be a semi-articulated tractor tail rotor system again there's a there's a mechanism inside these these move together they're not independent moving uh the left and the right elevators are not independent moving check this just to make sure it's in good shape this looks good again radar altimeters right here these are the original flares that were in the aircraft and these are just signal flares um kind of like what we put on our transponder i guess whenever we get to the airport we don't have radio or we don't have a you know we don't have something else so there's a particular there's i forget the color there's four colored flares that are in here pretty much on all soviet old soviet aircraft and one indicates you don't have radio one indicates you may have injuries on board another one indicates uh some other fire on board or something like that so this is something to visually signal the tower as you're approaching home or whatever to sort of get some sort of help whenever you do land all right over here this is whenever we use ground power this is a standard 28 volt uh ground power here it says 27 volt as you can see here so i guess it's 27 volt but we use 28 actually we like to use 30 volts uh it's it's russian so it likes everything likes to be bigger right so just it uh 30 volts works great with our apu this is another interesting story this is um well our standard 28 volt ground power units no problem whatsoever they've designed this darn thing to where so if they if they were if they were to invade us they could use our ground equipment because it works just fine here their ground equipment doesn't work in our aircraft so they're 28 it's crazy because uh if if we took over their their their installation their base or whatever they had a bunch of ground we wouldn't be able to use their ground equipment there's a couple little mods you could use a knife or whatever shave off a little bit of the rubber and it would fit in there but it's pretty standard this is the 28 volt system here so again we don't have to modify because it was designed for american systems as well this is the the 208 400 hertz system works just fine with standard 208 400 uh 400 hertz systems uh i'll also mention again i don't know that much about weapon systems but they did the same darn thing with the nose gun you can put 50 cal rounds in there so if they captured our ammo dump or whatever they could put our 50 cal in and it's a little loose but it'll work 12.7 is what they're using here if we capture their bait we couldn't put 12.7 in a in a in a 50 cal so it's just it's it's uh you know what it's enough to worry about oh that's neat oh that's neat and then after a while you're like wait they're designing it this way so uh where was i uh this is air pressure and presently it hasn't been running so i don't have any air pressure here why do would i need air pressure and is this the air pressure that we're talking about to start the engines no this is this is the compressed air that we're using here that we hold on board uh the brakes so pretty much all soviet aircraft there's a there there are some exceptions some of the high speed stuff doesn't use hydraulic and some of the stuff that's operating in in lower temperatures it uses hydraulic as well but pretty much everything uses a pneumatic uh brakes and again this sounds like a truck you pull the pull the brake and you do a let off the brake in here that's sort of like a diesel truck or something like that so i don't have any uh don't have any if if we were taking off right now i'd go get some nitrogen we'd put a little bit of uh we'd put a little bit of nitrogen and put a little bit of air this is a service panel for our hydraulics so again we have our uh and and i'm sorry i don't know so one of them is going to be main one of them is going to be backup and one of them's going to be utility i don't know if i just pointed to the right ones or not but that's the idea here is that you have a supply uh you have a supply and a return for each of the three hydraulic systems so while we're on the ground we can put some 400 we can put some 208 volt power we could put our hydraulic mule on here and we could actually with that configuration we can do we can test every system on board the aircraft except for one and that's the generators the generators actually have to be moving for there to be but we've then replicated we can replicate and test all systems on the ground so this is the battery on this side and again just the battery box and we've we've replaced we've replaced their batteries and and the soviets were notorious for having horrible batteries and so what we did was i'll just go ahead and show you so whenever i came down to lancaster there's a bunch of l-39 guys and again the problem with these lead acid batteries or whatever else is whenever you go inverted then you've got you got the potential you got you got lead acid running all over your aircraft so that's not a good solution this aircraft doesn't go inverted that's not that's not the point there's they were already using gel cells here so we looked at these gel cells and they had these silly gel cells were a thousand dollars a piece or whatever and so what we did was and these need to be updated but uh what we did was just found these odyssey batteries and these pc 925s are great and so you can see here right here we got two 12 volt batteries so we're running this off of 24 volts again 24 volts it would like to see 27 volts and we like to put 30 volts so it's just and and we've tweaked our the system down to where we're not over volting these guys right now so they can charge up nicely and in flight these batteries have done really really well they've uh they um they hold the charge really nicely they charge up and hold the charge really nicely something else thing something we don't think about so much but these aircraft designed by the soviets majority of the soviet union was way north of where we are and so everything on this you're like what's that for why would they do that it's designed because they're designed to be operated in real cold temperatures de-icing systems and whatever else this is this right here uh you have this port right here and where the battery i'll show you right here this actually is where the batteries plug in there's a bus back here and there's also a place where this little rubber grommet fits in right here what it does is it supplies heat so it puts heat back here so that doesn't your batteries don't freeze up so again just just more uh crazy little things are like what would we use that for the answers we wouldn't use it at all that doesn't make any sense with where we are here especially in texas but um anyway uh and then you know you've got the heat coming in but this is the little ventilation port over here so those rascally those rascally guys were thinking of everything here great engineers great engineers again same same fold up system this door comes down blaze uh the the wheel comes back in there with this door fixed on here and then this comes back up in here in one motion check this right here make sure we're in good shape here it's a static wick right here these are formation lights right here we have we have formation lights here and then we also have lights that are used for formation on the blade tips so we can turn the formation lights on whenever at night and flying in formation and it gives a really really good it gives you really really good sets of reference points to line yourself up and to keep a good good tight form or keep your distance on the form whatever you want there this this is broken this is another one of those friend or foe indicators it was actually a dome that's over here so uh i just i uh we need to replace this but again this is not so this is not a system we're using um another system that we ought to probably think about restoring on this aircraft uh i'm looking right here this is a gopro mount right here and we have put a gopro here on a number of really really neat shots here but this is actually a uh inside here is a see if we can get in here may not have been open since we painted the darn thing there's a camera in here and this is actually the original camera i need to look in there and see if there's any film in the camera um it's just use it likely it's using 35 millimeter film and uh so this would be a real interesting place to put a gopro probably also um and you can see there's just there's a filter here whatever and then this right here i i will tell you again uh we we talked earlier about this gopro and the heat problem you put this right here and you can see all the carbon here what does that indicate exhaust yep we're getting direct heat downflow and again whenever this is lifted up and we're in flight nose is low we're getting heat right across here this gopro doesn't stay on for more than 10 minutes it doesn't seem like once we're in flight so all right and and then again part of the pre-flight is we do lock these doors up but part of the pre-flight is we want to make sure that everything opens and closes so i would just always come back over here open this up and this is the other side of the crew compartment it's actually i don't know i don't know if it'll see this is actually kind of roomy now you put eight guys back here and this is not going to be roomy but for a couple of people this is this is uh for me anyway having been brought up in smaller helicopters this is a lot of room the uh interesting thing also is there's a hallway right here and i think you were looking down the hallway earlier the hallway um you can see yep really sort of live in there he's looking over the pilot's shoulder checking the lights and all that in the in the cockpit there's also a bunch of races on either side this little hallway there's a whole set of breakers on this side and fuses and breakers on the other side push pull rod there's a lot of things that the crew chief can actually work on while we're in the air traveling in the aircraft my crew chief something must have happened with him he's he's very he always wants to make a point of saying don't get near the door during flight so i these things these doors whenever they come open they're kind of like this and you know could they be out here flapping yes it's it's it would be a dangerous door to be open during flight so uh in fact we typically just ask people to throw the door down like that whenever they're coming out and that way it will catch or whatever um one other thing i want to show oh this is actually uh this aircraft has a nbc system on it so it has a filter on it for nuclear biological and chemical and you'd say well do how can you do that with it we're pressurized also so right here you can see the um the pressurization right along here and yes these are all active in systems so this is just a like an inner tube a real thin sort of inner tube or whatever that runs around here and it also runs around all of the openings here and also in the front cabin and in the pilot's cabin and so what we do is we put a little bit of pressure in here and it inflates these and then it makes a good tight seal and you're not going to open the door whenever the seals are are pressurized like that so that allows for uh then then you can have a pressurized cabin and yeah it's for pressurized cabin for altitude also so you don't have to have oxygen or auxiliary this is uh this is going to be where a great place to put golf clubs or something i guess someday this is actually where the frinder foe system was there's a place here where the base system was excuse me and then there's also a control panel that i can show you later on we've we've actually put some extra breakers and and switches up there in that panel they had plenty of area there so we wanted to put some additional avionics switches in so this is where that we're looking for some parts here so if anybody knows where if anybody has a couple of spare fringe or photo systems we're looking to put this into here just to see if we can get it working as well this is the co-pilot gunner uh co-pilot uh seat right here copilot seat or co-pilot gunner and this is this is actually this this style of uh canopy opening is if you've seen an l29 uh even a mig-21 very reminiscent of of the way those out you just push the push the button here open this and then again l 29 mig 21 use exactly the same sort of stand to keep the the cabin or keep the canopy open like i said this is the co-pilot gunner seat here so um look most of the controls up here are are not for flying the aircraft the idea in this aircraft is you fly the aircraft from the top and you you deliver the weapons from down here so the controls are very minimal you have two pedals you have your cyclic and you have your collective over here and that's pretty much it i have a i have an artificial horizon over here but it's on a 45 degree angle you get socked in the mess and a horizon at 45 degrees becomes completely in fact i think it becomes more deadly than anything else there's nothing else to use as far as navigation up here you have a couple of gauges if you want to come over here actually and look back over here we have a couple of gauges here uh i got airspeed and metric we have which is kind of useless as well we have altitude and metric uh which airspeed and metric is actually okay but airspeed or excuse me altitude and metric completely useless i usually just set it on zero and we're returning to the field i kind of do the calculations here or whatever uh we need to replace this and then i have rotor speed right here and then my n1 my engine 1 engine 2 rpm percentage right here this is pretty much this and this artificial horizon here my cyclic my collective and my pedals that's it as far as being able to fly the aircraft from the front all of the rest of the buttons and everything have to do with uh launching weapons and uh and delivering delivering the weapons um there's a clock right here and i'm sorry so there are some other things there's my gear up gear down we can do an emergency gear blow from up from the front we can't start it from the front and we can't kill the engine from the front so there's a way to deploy gear you can't retract gear once you've deployed it here you're you're kind of you're stuck in your situation so but when i get to the ground can i stop you i guess you can just sit there and wait for it to run out of gas or somebody else to run up and and help you stop the engine from the back or whatever um this is the guided missile yeah this is where you you do the various operations for the guided missile system we get back out i'll show you the how the windows come open there's uh some window or there's a there's some louvers that cover to keep the the 12.6 brass from going over into the missile site so it's closed right now but this is you basically you come in here you sight everything in and then if you do have the controls active then you can actually use the controls this would be extraordinarily uncomfortable it seems to me like to use this way but you can guide the aircraft here the other thing is these are guided missiles maybe you would use this for the guns i don't know this is actually what you're using to move the guns left and right up and down like this it's it's a it's not mechanically coupled obviously because i just moved it's not mechanically coupled with the gun it's electronically coupled with the gun which raises some real interest in possible engineering experiments in the future but what you do here is you actually you put your hands here and then you sight in over here and this is where you're flying the missile into its target and so you bring it over here you so um you got this right here you've got these controls right here again we haven't fired anything i haven't flown fired anything off this aircraft so uh i'm i'm pretty unfamiliar with uh with the web but looking forward to getting used to what what's going on right here so this is the the guided missile system right here and then this is the gun system right here um this is where you can set the guns i guess your your launch rate of your guns you can do some some uh launch rate you can your burst rate i guess is what it would be called of your gun and then you can set different elevations and attitudes here um there's drop angle burst height elevation differential so there's some controls that you have over here that i have no idea how to and then there's also where is it this is i believe this is your flare system right here there's also a flare panel in the back so that your your decoy flares uh to get away you could launch that from here um and then seems like there's oh our where's our ub32 then we have a ub32 launch system as well somewhere in here and and again you can you can dial up how many how many rockets do you want to send at a time do you want to send you know two a second for a second eight a second 16 a second or whatever so so i've got some other radio controls in here but for the most part again this is the this is the the this is the cabin for delivering the weapon systems on on on the other side so do you want to get in here take some pictures or do that after the fact okay all right another friend or foe these are actually pitot tubes right here we have one on this side one on that side very common soviet system even in l29s l39s mig-23 mig-21s do the exact same thing rather than joining these up again it's a redundant system we've got an airspeed indicator here we've got an airspeed indicator there why not connect them up separately they do um that way if if you do take some fire on one side and you have bad air speed indicator you can ask the person in the other side hey what's the current air speed and you've got a whole different system uh calibrated or calculating that for you up up up here whenever i did like this this would actually move this cone like this and then it's just sending an rf signal back and forth and that's how you're actually guiding the thing is with a little little bitty rf guidance system here so this moves with this system right here um i guess the rocket moves with the thumb with the little thumb joystick and then as long as we're talking about that i mean excuse the tow bar here we left that on but this is where whenever you're using the missile system this is what i'm actually looking at right here and siding and gauging everything in there apparently there's some thermal capability in there to where it's helping you to track where the rocket is because you're looking at the back side the fiery side of the rocket so it helps you keep track of where everything is and all and then also where you're where your target's going to go so and we skipped over the gun but this is the uh this is the uh what is it um a yak b i guess is what this is referred to as this this is a this this is not real this is actually the real one i picked one of them up it's over 100 pounds again one of the one to me just from a size and and it just so you got 100 pounds sitting what 25 feet forward of the of the center gravity of the aircraft and again whether it's on or off if you look at the weight and balance it doesn't matter it doesn't move at a millimeter whether it's on or off and to me that's amazing you know we were looking at the tail rotor earlier and talking about it earlier a tail rotor gearbox is is about three times the size of a schweitzer main rotor gearbox or a robinson main rotor gearbox probably weighs 250 300 pounds again that sits 45 feet aft of the center of gravity now you take that off and i'm sure it would affect the the cg of the aircraft um we do the cg before every flight obviously but whether we're putting two people in where they're putting one person in yep this aircraft is actually certified to fly a single pilot um which is a crime you got to always take somebody with you when you're in this aircraft but i'm i'm sorry i uh if you put five people in the back and one in the front way the cg doesn't move it doesn't move a centimeter for a raft so the the main reason for these right here i'm sorry i may or may not mention this earlier we close these right here because what you're doing whenever you're shooting the gun is you're exhausting the brass right here so we don't want the brass to be exhausted off into the optic i say we don't want the brass to be exhausted into the optics actually a a data sensor is taking relative wind measurement information and feeding that into these analog computers to help you guide the guided missiles and so there's a million different things about these aircraft but one of the more interesting things is this right here this is plexi this is plexi on the cabin that's plexi on the cap this right here is i guess they say there's no such thing as bullet proof gap glass so this is bullet resistant glass and it's just a bunch of plexi and glass squeezed together in there and that's direct so if you get a glancing blow i'm thinking you're probably going to be okay but get in behind the glass the the other thing just from a survivability standpoint that you're like if you're in this aircraft so if you're a helicopter pilot you love the visibility that you have if you're in this thing you're going to say man this is a helicopter because you don't have any visibility um you're down in this bathtub so to speak and i'm guessing whenever people are firing you want the sides to be even taller you want to be even lower in the in the bathtub so to speak so um again you can get in here your head's going to be a bit exposed if you're doing if you're uh if you're sighting in the missile or whatever but i guess if you're getting near the fire you can sink down in your uh sink down in your seat or whatever um and then get get in behind this you know get them get them straight ahead again if it were me i say yeah i want that between me and whatever the bad guy is or the opposition is as opposed to just this plexiglas over here interestingly also this right here you say well but this this you know aluminum siding or no this is not aluminum this is all stainless steel up here and this is like quarter inch metric but this is roughly a quarter inch stainless steel here if you notice you you have rivets right here so you have aluminum right here you have all these screws and all these screws that are running up here this is all one piece all the way here this is all one piece of quarter inch stainless steel again think how far up we are from the cg and how much weight this is we've got some of these panels that we pulled off of another aircraft they are crazy crazy heavy and there's an identical on the other side and this door even has a piece of right here so again this is this is some pretty good shielding that you have from from from the opposition's fire or whatever but what i think is really cool is we took one of these aircraft all the way down we had a third aircraft that didn't make it here it had an accident ground accident being in transport this right here you take it off and the whole front of the aircraft goes really floppy this is actually an exoskeleton this is actually support this is struck a structural member within the aircraft so in addition to being a shield if you will uh armor for for you and your pilot co-pilot whatever it's also an exo structure and it's just there's a very very thin layer of support in here just sort of support where these things are screwed in so it's it's an interesting interesting uh design okay so welcome to the cockpit of the mi 24 uh hind helicopter uh just i just we we've already looked at the aircraft from the outside but this is the inside so again this this door is completely armored the material along here this is armor as well this is uh the exoskeleton armor that holds on the front of the aircraft um we i'm obviously i've already stepped in here we're going to go up top we would use this as a step this can also be used as a handle there's a lot of places on the aircraft they're dual as both handles and steps we step here and always tell the pilots do not step here or else you can't use air conditioning because and there's been a lot of people have put their boots up here so you see the paint's been rubbed off basically once you're in here uh you get it closed up with your cold weather hot weather it gets it gets warm and so you want your air conditioner and so uh this is the air conditioner we don't want to use that as our uh as our foot for our feet to be on that because then we will tear it up and we want we won't have air conditioning for our flight so um we we just in here we keep some some uh books in here and then we keep a little zeus nut fastener here that helps us with uh all the different uh batteries the the black box in the back where we have our hops things like that just just something for a pilot pilot maintenance tool if you will so if if you look in here so what we've got is uh this is just a little utility light right here but we've got where our fuses begin these are typically fuses that aren't serviceable by the pilot in flight you can see we've got them labeled there was russian labeling we've got them labeled with some tape over the top of them in english typically the um typically the flight engineer is going to be he's going to be here during a flight he's the one who actually kind of cranes around and is able to look at the the fuses these fuses if they blow this little center section it's it's on a spring and if it blows it will come out so you'll you'll see it kind of hanging a little piece of plastic on a circle hanging out of the middle of the fuse here so he can crane around look in here pull the fuse look at the value and typically go in the back and find there's there's additional fuses on this wall over here he can find fuses that aren't currently in use or that we're not going to be using in flight he can swap the fuse out if that's needed in flight these down here are circuit breakers we bring all the circuit breakers on like so and then we have right now we have the guns and the arms we have those disabled because we're not those are not active systems on the aircraft right now but if we needed to bring all the all the breakers forward we would do that the same sort of breaker uh bringing all the circuit breakers on the same uh configuration exists over here on my left side so the general layout of the of the cockpit whenever you're doing your pre-start typically you're going to start over here and you just sort of there there's a couple of switches that you move back and forth but in general the flow is that you move around the aircraft and then finally you wind up over here on the right side and then once the engines are started then your attention starts to go to various different places in the cockpit that need your attention so the the different places in the in the helicopter um for example over here this is going to be navigation and communications over here this right here is going to be your fuel section right here this is going to be your fire control system and your fire panel right here now all of these systems all of the systems report up to this right here which is your master control uh indicator area right here these are all just standard navigation gauges so again as we're starting up here and just just to kind of fill in the gaps this is where all my navigation my fist systems are all down here underneath the collective on the left side you got the gearbox you got the uh what you do with the gear right here within the box this is our pneumatic systems over here this is actually a radio system here our neutral gas system here these are our hydraulics right here and then we have some nav lights that are sitting up here they're kind of in an odd place but they're they're they're for landing so they're right here where the gear is and then you'd bring your your lights on things like that um and like i said there's some other gauges this right here is where we cage our gyros we do a cage on our first gyro and then we do a cage on our second gyro in fact you know i can actually so i can bring some of the systems up we've got the inverters on right now so i'll go ahead and show you we could this is where my communication i go intercom one intercom two i bring on the radios right here with those three i'm not going to turn on my doppler system or my radar altimeter while we're here in the hangar but then what i will do is i'll go ahead and start bringing the the gyro systems up right here and some of the um some some of the i'll bring up my gyro so that some of the systems that need the gyros can start getting calibrated and that that actually brings up a couple of lights over here that's starting to flash at me and then let's see i need to go ahead and bring mains to bat up over here as well and so the systems are slowly starting to come alive so um again this this is fuel system right here these all these nine switches need to be up if we're starting the aircraft master control panel over here um down here i have a couple of air conditioner ducts it looks like your standard air line air conditioner uh turn i guess you turn them clockwise to turn them off and open them up turning them counterclockwise um we've got a g3x system that we just put in to this helicopter we have displaced no um instruments there was just this blank space up here it was this bank a blank sort of uh aqua marine that all the soviets seem to put in all of their aircraft whether they're mig-21 mig-23 mig-21 all of them have kind of this green uh yucky color or whatever and there was just this big green area right here so we decided to build up a box and put this we've got some future experiments we're going to be putting in these areas right here so we'll be expanding this box over time got our clock right here which is one of the most hotly science seems like sought after devices whenever you go over and they're picking up aircraft you always need to make a deal and say i've got to have clocks in them because the hardest things for those guys seriously to find are putting the clocks in in the the aircraft mechanics apparently love having them families of mechanics love having them for christmas or whatever so uh the clocks are in hot demand over there um fuel this is our fuel indicator right here um we we uh we have one fuel gauge where right now we're switched on total we want to see how many liters we have in our first tank we we put this switch to one if we want to look at tank two and again tank one is the service tank on the left side tank two is a service tank on the uh on the right side and then tank three is that vertical tank that's behind the crew cabin you can see i don't have any fuel in it right now and that that tank three falls directly down into tanks four and five and you can see four and five i have very little fuel also so you figure tanks one and two have about 300 liters each and what did it say we were at we should be right at 300 liters yeah we're just a little over 300 liters you can see there it's think one tank two we're coming up i think it's technically 320 these these are my rules of thumb i think one and two or 300 each tank three has 500 even though it has just a little bit less and then tanks four and five have 500 each so it has about a thousand liters so that makes up the 2100 liters that and i usually 2150 i think is technically the number of leaders but that's how the breakout works here so we like to drive we like to drive the aircraft when we're in the total so we can see how many liters we totally have in the aircraft and you see right here we have about 700 liters in the aircraft so moving over here right after the engines get started this is where the pilot's attention will move real quickly you want to make sure that it once your turbine is going and whenever you have a turbine going um you're going to have heat you're going to have heat and that's going to indicate okay i have the aircraft egt is going to start winding up here this is good then your eyes immediately move over here do i have do i have oil pressure in the turbine and then do i have a little bit of heat building up in the uh in the oil return out of that if i don't have either one of those moving then i need to immediately shut the aircraft down or shut that engine down something's wrong so that's what we're looking at there so i deviated i'm in sort of the the start procedure let me sort of go through the continuum here so this right here as a part of the checklist you look at you say uh gauges uh temps and pressures this is where the pilots they really this is where he's paying attention you have your attempts and pressures for both of your engines and then for all your gear boxes are over here as well so you just want to make sure all your gear boxes are properly pressured up and they have they have proper temps and then also you're looking at your turbines um and then as we kind of move back over into here this is where um my environmental control systems are here where i put my filters on i put my air conditioning on put my heating on again this is a pressurized um we have a pressurized cockpit here this is where we we monitor all those systems this is the de-icing system on the aircraft we don't use the de-icing system so i can't tell you about any of these uh any of these right here and it's we just don't have it active we don't plan to activate it on this aircraft this right here is your ac power system so again the power in the aircraft once everything is started there's a uh your derivative power that's going into that's going into electricity is coming out of the auxiliary gearbox behind us the auxiliary gearbox has two of these 200 amp 208 volt 400 hertz uh generators or uh and and they are there's a synchronization we flip them both on here they're not obviously the aircraft's not on but we'd put these two on these two red lights would go out if the aircraft the generators were producing and then what we're looking for here is a green light that comes on here and indicates that both of the generators are in sync with one another so that it can bring them together and then we can use the uh the merged output of the generator we have two amp meters here that are also telling us individually how many amps the the generators are having to produce for the load then we sort of move over here right now the noises here in the background i've got a i've got an inverter on that allows some of the ac systems to be working and this is what whenever you're on the ground and you're on ground power this is what you would be using whenever we get the power going on the on the airplane itself we would flip this down the light would go off the light so light goes off light goes off this light goes off the green lights on there so the the goal here is to get rid of all the amber and red lights and get everything to go over to green once all of that happens then there's a light over on the master panel that will go it goes from red it goes to dark as well it goes out so that that's what we've got here the ac system here that's where all the power in the aircraft once we're underneath under aircraft power this is where it derived then we'll go over here and we'll flip on the inverters these two lights would go off that means we're making dc power out of our ac power then i'd be able to flip off right now i've got external power on which is how we're doing this right now i would go ahead and take my mains to bat off i would put this off and again kind of cleaning up the lights over here getting everything to go uh either to go off or to go to green so um that's that's kind of going left to right in the cockpit um yep yep good question so in in the rear cockpit the primary purpose is to keep the aircraft in the air and to keep the systems working within one another and and truly this airplane this this aircraft the pilot sitting in the back is less of a pilot and more of a systems manager um it it i'm i'm not being falsely proud or anything it doesn't take a lot of skill to fly this aircraft per se just to hover around into flight now you get into maneuvers and it takes some some real skills to do that but what you're really doing here is you're keeping the aircraft you're keeping it flying but you've got to keep the systems interconnected the way the soviets did things with they didn't build they didn't say okay we're going to build an aircraft around this gun and it's going to support this they would tend to take things off the shelf they would take a system that works a doppler system for example that already works don't go reinvent it same doppler system that's in here is in the mig-23 pull it out stick it in but the doppler system needs to work with the navigation system well the navigation system might be off of an old tank system that they developed in world war ii or something like that um another example is the radar altimeter why go reinvent the radar altimeter just go ahead and use the radar altimeter that's used on a similar aircraft or that would fit in the space that's allocated the point is you've got all of these systems that are sort of put together from other technologies and your primary purpose in this seat is to keep the systems linked together keep the amber and red lights off keep the green lights where there's green lights on and keep the aircraft going straight and keep it off the ground now one thing that you can do here is there like a there are backup system so what you primarily do here is you fly the airplane what you primarily do in the nose of the aircraft is you you use the weapon system if something happens to the person up front and you need to want you you need to use some of the weapon systems this is your this is your weapons panel right here so this is sort of the back up weapons panel if you will and as you can see you're flying this is not comfortable to get down here you're not going to be flying the aircraft you're simply working on bringing the weapon systems online um this aircraft presently doesn't have the weapon systems active we're we're slowly in the process of bringing them active and i'm not going to be able to give you a whole lot of insight these are labeled they've been labeled in english so um you read the switches and you know as much as i do about this but the bottom line is primarily up in the in the top cockpit you're flying the aircraft keeping the systems linked together but you could in a backup capacity you could for example store the gun in the forward neutral position and then start firing the gun you can't slew the gun from the back seat like you can in the front seat but i do have a switch somewhere in here where i could activate that and it would pull the gun to the center position and up to the neutral position so then i can start using my gun side here to actually aim where my where my bullets are going here and again i you know there's a lot of little moving parts here we've left all of the original equipment to the extent we can in this i can't tell you exactly i can't tell you exactly how this i can tell you we've turned this on before and there's a little cross hatch that appears kind of like in this hud system here or whatever that it does provide a little cross hatch there so i'm imagining you get your tracers out there you figure out where it is at whatever range you're at and then you make the appropriate corrections and then you uh you take out the target again i'm guessing so but yeah that's what this panel is right here that's your uh that's kind of the backup weapon system for the uh for the aircraft so uh as i've said the doppler system even works here so there's this there's this little thing right here and again this is our this is our notes for for uh this is actually our cheat sheet here our master control panel is still all written in russian so the question is okay do you read russian no but i can look over here and right now i've got this red light on and i've got this yellow light on and i can come over here and it says i have a main transmission pressure low main transmission pressure and then i've got an electrical system panel uh caution light here as well so yeah that makes sense i don't have any pressure in the care box because it's not running and i do have red lights over on the electrical panel as we saw earlier so that's what this is here but underneath here is a plotter let me see if i can get to it here this plotter very cool it's um i'll put this back up the plotter is actually kind of an old etch-a-sketch if you will you turn these knobs here horizontal and vertical what you would do is you would put your uh you'd put your sectional behind there now it you really can't put u.s sectionals in here but you'd put your metric adjusted uh sectional in here you would adjust it to let's say where you are let's say i'm right on the intersection right there and then you would start the doppler system and then this cross would start actually moving around with where you are it's just taking the doppler input it's adding the north south and it's north north south relative to the aircraft and east-west or left-right relative to the aircraft it's putting it in here and then positionally it's making adjustments for where the aircraft is also with with the map of the earth and so this is just using uh old doppler technology to actually move the crosshairs on this this system is actually working on this aircraft and it's just as inaccurate as uh as as it was whenever it came off the off the line again it's very accurate whenever you're within where it starts but as you get further away and and again you look at some of the old piloting skills the pilots and skills you think you're somewhere but then you find a landmark and you readjust your bearing that's what you would do with this you'd cross over a water tower you'd kind of move the controls so you re-center the controls on the uh you'd re-calibrate your control on top of the water tower or whatever so anyway working system um we've had some people that are trying to talk us into putting some gps screens here but i want to keep the we want to keep the old the old stuff as as usable as we can so once you've gone through and you've set all your switches in your preflight to start the aircraft once again we start back over on the left side of the aircraft so there may be a couple of additional switches that our checklist would tell us we need to bring online as well in advance to the start but this is where we actually do our start so this this line right here d marks on the back side this is where my apu starting control is and on the forward side this is where my uh my main engine start is going to be so there's a number of different types of starts we can do we can just start without fuel we can do a start with spark we could do a smart start with fuel and no spark so there's just just from a standpoint of checking uh the mechanical say let's run fuel this time and not run spark or whatever it's just whatever the okay but mainly we we the pilots would just simply put it in the start position you'd push the white button here it starts uh what what i refer to as a music box because if you've ever seen an old player piano that has like a belt that goes through and it's got the little whatever for the different keys that need to be struck we've got one of those in the back of this and it starts this thing starts up and it's on a 60-second belt and it's got little dots in there where these little switches and contacts are and so it goes through the progressive system of starting up the apu by by applying power first and then it applies to the second stage of power that would be the next switch then it actually connects the switch to start sensing whether it has appropriate back pressure if it doesn't then it'll shut the system off i mean this this thing will not let it it it's actually set up to where if things are not going correctly it will shut itself down so it doesn't have to rely on a pilot to clear that sort of stuff out so it it's actually it's very cool so there's there's a music box in there if we want to stop the music box or if we want to reset the music box then we push the red button here and that'll stop the process it'll disable all the little micro switches that are in there and then it will run this little belt back to the beginning and then we can start again we've had problems with a couple of them where the little motor was running them just a little bit over to where it was just like a second and a half whenever it ended it was a second a half into the start of the next cycle and it wouldn't start because everything was a second and a half off so you have to stop it reset it back to the beginning and let it go through the full cycle so that we can get a good apu start and again remember the apu is critical to start the engines because the engines are started by via air pressure or so-called upper system and so that's where we would go here we would go to a left engine start here uh or right whichever way we'd go left engine start we'd push the start and then my attention would move to the front of the panel and and again kind of older technology so my finger stays depressed for about 15 seconds to make sure and then my attention starts i'm looking for heat once i got a heat indication or egt indication then my eyes start moving back over to the pressure gauges and template gauges to make sure that we've got a good start if we've got a bad start then um then i would push this now a real key thing that i missed in the whole start of this thing now the apu the fuel starts automatically once i see that we have about 15 percent on my n1 what i'm going to do is i'm going to introduce power so i'm going to do that as though i'm flipping okay i've got left engine start i press left engine start i start to get up to about 15 percent on my n1 and then what i'm going to do is i'm going to introduce power by letting that down right there i've got my closed so i've got all the fuel gauges and fuel so i'm not doing anything here but now i've introduced power at that point or invented his fuel excuse me at that point in time now my attention is looking as soon as i get heat i know i've got an ignition as soon as i got into ignition i need to start moving over to the pressure and temp gauges so that's kind of the that's the rough without me looking at this uh the checklist that's kind of a rough idea of how you start the aircraft after the left engine or right engine whichever one you choose to start after it started you go through a procedure there's a couple items on the checklist you do a couple of hydraulic checks the the rotor blades are connected to the engine so it's not like you introduce rotor or whatever once you get everything going once it gets up to about 25 30 percent the rotor mass is going to start turning and so we get the rotor mass turning then we can start doing some hydraulic checks and things like that before we start the second engine on this aircraft just to kind of even out the starting of the first engine and the second injury number one on the left number two on the right what we do is on odd number days we start the odd number engine first and then on even number days we start the even number first and then how do we keep up with that well if we start the even number one first then we start the odd one second so we're going to be in the left position and the second time we're here we look down and it says left so even the pilot doesn't have to think about that kind of system it's uh it's almost pilot proof if you will so anyway that's how you get there that's how you basically how you get the aircraft started that sort of completes our walk around on the outside and our little runabout on the inside of the aircraft from from the mi-24 hind model d helicopter [Music] you

I now know how to service an Mi-24. AMA.

First a MiG-23 and now a Mi-24? I love this dude's channel.

I never knew the crew compartment is soo small. I can't imagine 8 guys will full gear squeezing in there and being comfortable for any length of time. makes the blackhawk look like a station wagon in comparison, , that door looks like a easy way to knock your head on the way out if you didn't lock it. i'm amazed I haven't seen more hinds in service run with the doors off like some armies do with the Mi-8 rear clam doors

Interesting that he uses the NATO naming convention "Hind". This sent me down the rabbilt hole, where I found:

​

Soviet pilots called the Mi-24 the "flying tank" (летающий танк; letayushchiy tank), a term used historically with the famous World War II Soviet Il-2 Shturmovik armored ground attack aircraft. More common unofficial nicknames were "Galina" (or "Galya"), "Crocodile" (Крокодил; Krokodil), due to the helicopter's camouflage scheme and "Drinking Glass" (Стакан; Stakan), because of the flat glass plates that surround earlier Mi-24 variants' cockpits

This is awesome. The MIG-23 and A-10C walk-arounds on this guy's channel are really good too.

That Hind is like almost literally a flying TANK.
