How Few TAIL PROPELLERS Does It Take To Break The Sound Barrier?

welcome back to the channel and today we're going to be trying to break the sound barrier with the 1.8 new propulsion block called the tail rotor ta tail prop hold on what is it called probably know what it's called tail propeller and I believe that today the day that this video is out is also when the 1.8 update comes out as well as the rescue pack and I think it is the rescue pack that contains this tail propeller um but uh this is a new source of propulsion so you guys knew what had to happen we got to now try to break the sound barrier with it but I also just kind of want to test it uh in general to just see how much power does this thing actually have cuz all of like the real sources of thrust that are designed to be like primary thrust have power settings this has power 300 this is power 750 this is power 250 80 60 and so on but things that are like supplemental thrust tend to not have power ratings so we got like the gimbal jet actually interestingly enough I don't I wonder why the propellers actually none of the propellers have power ratings only the non-rop stuff oh the engine the okay there's a little bit of inconsistency on I don't know why some have power ratings and some don't but anyway this one does not have a power rating but 40 kg of weight hold on a second this thing weighs as much as this thing wait a minute get it get it wait a minute like like wait I want to see how powerful this thing is how much weight can this uh thing lift that's oh the attachment points okay this thing's actually a lot big it keeps it keeps getting it keeps being bigger than I think it is unfortunately uh you can't really attach it on its face but I do want it to be on top of this seat here and I should be able to attach it pretty simply with some flat connectors like this and this is 70 kg so I mean I guess it does have to be able to lift its own weight too so we'll just call it uh we'll just call it what the weight is even including the propeller itself so interestingly enough it is default to A and D for turning so it is clearly designed to be a uh a tail rotor I mean it's called a tail propeller so it's not like I'm surprised or anything but we're not going to be using it that way and I feel like most Creations are honestly probably not going to be using it that way but there's going to be a lot of valls with this thing all right but we should be able to lift this on away oh no problem o this thing's actually look how whoa we're going we're going really fast for a single propeller 266 km an hour we need to get to like 1234 km an hour to break the sound barrier and with one of these going straight up against gravity that's actually pretty good what are the aerodynamics like on this thing oh that's why that right there is why okay I I think this is going to be a pretty easy task oh well so the question now becomes not can we break the sound barrier here but how few of these rotors are we going to need to break the sound barrier can we do it with one can we do it with I mean I guess anything after that isn't quite as impressive can we do it with one all right but how much force do these things have let's find its weight limit I think it can live to this much let's just see let's see if I'm right above this come on come on come on come on come on come on okay all right I guess it's not that powerful let's take off 50 kg okay I'm actually really surprised by this it looked like it it looked like it had so much power I guess it was just it wasn't power it was just aerodynamic efficiency oh here we go okay so it can lift 120 kg we have to find I want to find the actual maximum limit here 142 even this has to be like the last one all right so here's 142. 6 oh oh that is the gentlest takeoff oh oh no way no way that actually works I think we found it I don't think we can go .1 kg more than this look at that we have liftoff this won't go straight though for some reason okay so this thing has 142. n kg of uh thrust essentially so what does that mean as far as breaking the sound barrier I have no idea uh we are going to to I don't I don't I didn't really go in with a plan I was just going to do it it's just I broke the sound barrier so many times I don't even think it through anymore the main thing is going to be aerodynamics because in well actually in this direction the aerodynamics aren't too bad you can see but they aren't the best they could be better and that is what we strive for is better but let's just see how many do we need to make this thing break the sound barrier kind of the fun part to me with breaking the sound barrier is starting with just a bad aerodynamic vehicle and brute forcing it and then fine-tuning it with and using like finesse and function aerodynamic functionality to reduce the cost to reduce the amount of uh thrust that we need to break the sound barrier so I actually don't remember if these flat connectors affect the uh aerodynamics I don't think it does we're going to need those in between every single one of these because otherwise they can't be connected to each other so let's start with 10 all right let's see if this can break the S barrier with no efficiency added into it so oh we're going to do it oh my goodness whoa we might not do it actually we're going to hit the wall first that sound though that sound just sounds like it's going to break it's going to overheat all right we're still going this map's a lot bigger than I remember um we're we're still going there it is Boom okay so I I actually I'm kind of surprised 10 didn't do it like I said we haven't done any aerodynamics yet so how many to brute force all right if 10 couldn't do it can 20 do it probably not actually cuz 10 got us up to 800 there's definitely going to be a lot of diminishing returns 900 can we break 1,000 we broke 1,000 this might do it we have to get to 1200 oh it's it's slowing down so much 1234 come on we're not going to do it all right here we go 25 look at this thing all right that should do it yeah yeah we're going to do it we're going to do it now there it is there it is okay so we probably maybe like 24 could have done it too but it took about 25 to just brute force your way through it um man we're not even going to slow down oh these things can go reverse here we go the wall was right there I slowed down just in time all right so now for the fun part now that we broken the sound now we confirmed these things can't break the sound barrier if you just put enough of them how few can we go so in order to do this we need to make this thing as aerodynamically sound as possible and that just means everything has to have these 4x1 wedges just covering it everywhere um and I'm going to do the wedges sideways so that way we're not having competing lift and like not just no competing lift forces I don't want to have to manage that small grid block like that and then I can use this piece just like that to cover the aerodynamics um these are going to go up here another grid block to fill in that space and now we also we do need the top of this yeah that needs to be covered good so you can see the hit boxes are going together there and then we got this one this actually is this going to be this isn't hard to make like the perfect aerodynamic uh shape here and then like that and then all we need is this and this that kind of looks cool I like this aesthetic right here all right but now I think we have perfect aerodynamics every oh these are not attached so I'm going to have to go down and down and then to counter that we go up and up and I'm just trying to be as neutral as possible so all of our force is going in the straight Direction okay so now let's see how fast we go with the same amount of propellers we were kind of at like 1270 around there uh let's see where this goes now oh yeah I hope this thing doesn't like spin out or anything all right there's sound barrier no problem 13 14 15 it's still going up 16 17 18 19 20 we're going to double the sound barrier we're going to go Mach 2 I don't actually know the official value of Mach 2 but 2600 is after yeah we we broke I think we broke Mach 2 here whoa whoa is just me or was that a much more satisfying like explosion Parts than normal that seemed like that seemed to behave differently than normally it was like really satisfying okay so how few do you think we need do you think we can do it with one let's go back down to 10 this should 10 should be no problem all right we got 10 now I think this is going to work with 10 the real question is like are we going to be able to get down to one I don't really know if I can create a better vehicle aerodynamically than one I have all right 10 yeah this is going to happen no problem wow okay 10 is no problem is this going to actually work at one I'm going to keep reducing it by half until we get it like I think we're going to get there though okay we're down to five can five tail propellers break the sound barrier oh we're going a lot slower for sure the acceleration mean is a lot slower but it looks like it's steady enough there it is okay five is able to do it this is this is it this is actually kind of concerning me a little bit um how much weaker that was as far as our acceleration goes but I'm going to go down to three okay here we go three tail propellers if this if depending on how much this struggles I think this is going to kind of tell me the information I need if one's going to do it or not uh-oh oh this is is like this is really slow going oh no is one not going to be able to do it one's not going to be able to do it three can't even do it what I was so confident in the aerodynamics of this thing I was like we got it no problem that was really close though hold on let me I want to try that again we're still at three could skis help probably not they're going to add more aerodynamics we don't want to add anything else to the uh profile of this the aerodynamic profile this is liter like we are the exact dimensions of the tail propeller and that's the best we can do 1,00 we're so close three I I really thought three was going to be able to do it I honestly thought I was going to be able to do it with one I might not be able to do it with one I don't think I'm going to be able to do it with one I can't even do it with three well hold on so now we did it with um we did it with five and we can't do it with three so is four even enough all right so I honestly feel like this could be the best like sh I'm going to change out seats and stuff but this might be like the best shape and if we can't do it with three then I don't know if we can change anything to actually improve that but here's four 1 2 3 okay four is actually like four was kind of easy but three is where it cuts off all right so maybe my seat was too heavy man look how fast this thing slows down do you have any this thing slows down faster well I mean that makes sense if it slows down faster than it speeds up um but like by a lot like the amount of G forces for the slow down deceleration would be way way more Okay so we've got four we know we can do it with four we have not done it with three yet I'm going to swap out to a lighter seat so go-kart seat might be the best bet here let's drop that down in there and that means we can move this in all right so now we're a little bit shorter I have an idea to try after this too uh let's see if the first of all can did this make a difference look at me in there all right uh we're at three we we got up to like close to 1,200 but not quite there I don't remember what the exact value was this is it's so slow it is so slow come on it's still going up it's all right yeah 1160 between 1160 and 1170 1170 we broke 1170 but it's pretty much stuck there all right uh we're struggling I don't know if that was much of an improvement from the other seat probably not weight really doesn't have a huge Factor at this like at this standard at this level that we're building here but here's what I wanted to try I don't know if these being up and down matters they should theoretically cancel each other out but I kind of want to see if sideways would be better now the problem is these aren't attached here however I can move these up to here change these these to be sideways again and then just fill this in with a standard block all right let's see if that makes a difference we were about 1 1172 I think I saw 1173 on occasion so I I think this shouldn't make a difference but it was just something I wanted to test out I'm like pressing the W button harder as if it's going to make a difference I should turn off my seat control cuz I think I'm pushing forward right now all right 1160 78 9 all right yeah we're cing out it's about the same 1170 all right it does feel more stable like I I feel like the fluctuation in the speed is it's not as much fluctuation as we had oh no well now it's kind of all right all right 1170 we're at 1170 so let's see if air control was affecting things cuz I was using W which is part of the air controls so that may have been putting pressure on the front of the vehicle that could have been adding a little bit more friction affecting our trajectory but now now we can confirm whether or not that's the case can we break 1170 all right it's it's looking like it's going to be exactly the same 1169 70 there it is yeah we're at 1170 H I can't seem to get past 1170 with three all right I don't like I don't think there's anything I could do better like if you look at this it is this is the these are the greenest of arrows you're going to get the only thing is like are these making a difference probably not but there really is no other way to attach them all right I don't think that's going to make a difference this is more of a thing that matters in the water but when we're getting this fine-tuned with our stuff sometimes it's just it's just worth trying things and what I want to try is adding trailing um aerodynamics I think the weight I add is probably just going to make it worse I know if this was underwater this would make a massive difference but um I don't think it actually has the same effect in the air let's see if this matters this thing looks so cool now all right we should go slower now yeah this is a lot slower okay that did not help in an air based environment yeah we're having trouble getting to 1120 why I don't think I don't I don't think we can do it with three I can't think of any changes to make that would actually help all right I have an experiment I'm going to change two of these to face upwards and I pretty I'm pretty sure this is going to cause me to flip over however I'm hoping it's going to be subtle enough to just make me slightly lighter on the ground and hopefully that'll increase my speed capabilities so let's see here I'm probably just going to flip over though once we start picking up a lot of speed oh there it goes wow that was actually really cool I want to do that again all right what speed did it happen at seven 8 900 900 is the point that uh you have to go 900 km an hour for those little wedges to just suddenly flip you up yeah I just you know double confirmed that that does does make a difference okay let's start reducing weight the only area I can really reduce a decent amount of any weight really is this top area so we should be able to get a couple of extra kilometers an hour hm this actually seems to be slower now that is very strange the aerodynamic profile hasn't changed we're still this all I did was change uh a 2x4 block here which weighs 2.5 kg I changed it to four these grid blocks which weighs a total of 1.2 like they I took out half the weight from here it should still feel in the same area I'm going to put this back maybe just something got a little bit changed with this creation I don't know should we get up to 1170 now oh I still have some of the blocks on the back that's why that's why it was slower I haven't reduced all of the weight I got confused there okay we can remove this weight this weight was also another source of friction and then if I remove this okay I was like something's wrong and it doesn't make sense now makes sense hm it's actually it's still struggling I was expecting it to get up to 170 a little bit easier but it's kind of not getting there it's kind of slightly worse still I don't think I changed anything other than just made it slightly lighter all right well I think uh I think I've reached the limit at least from what from what I can think of it appears that four which is kind of an unsatisfying number it's like five three and five are kind of good numbers and then you get to like 10 then you get to the even numbers 1 3 5 and then 10 15 20 but four four does not feel right I don't like it I really did not want four to be the number that we settled on I really wanted it to be one but just confirming here one last time with four tail propellers is this really what we need to break the sound barrier roke 12 and there go it's like it's easy for four it is easy for four we can probably break 13 look at that we broke 1300 with four all right I don't know without using any glitches and keeping everything just with aerodynamics the way that it's the way that it's meant to be uh I cannot get I cannot reduce it down to three tail propellers and still have the ability to break the sound barrier I don't know if there's anything I could change there you have it tail propeller sound barrier experiment is concluded now leave some comments down below if there's anything else You' like to see me try out with the new parts in the 1.8 update and the rescue pack as well and uh don't forget to go check it out yourself uh I don't know if it's going to be out before or after this video gets released but around the same day that the video gets released any if you guys enjoyed this video you'll probably enjoy some more that you can find right here on the end screen hope this video has earned your subscription anyway this has been scrapman and I'll see you next time bye [Music]
