The V2 Rocket - how it works, guidance

all right what we have here is a is a model of a v2 rocket it's one-sixth scale and it this is an actual real high-powered rocket that's designed to fly with an M motor with about 200 pounds of thrust this was built by Joe Hinton a friend here in Boulder Colorado for his level three the high powered rocketry in an amateur rocketry are designed to fly using solid propellant based upon ammonium perchlorate but if you look at the top here the actual v2 this where this line was was where the warhead occurred in this section here is where the gyroscopes and the radio control area and the compass would would cause for the navigation that would control the rudders this section down here is where the the alcohol tank was located followed down here by the liquid oxygen tank on either side of this they had pumps on either side that pumped a fuel and the oxidizer into the combustion chamber then of course going out the nozzle to the to the back they basically made this 41 foot long rocket that only one-fifth of it was actually had any kind of warhead in it the rest of it was part of their guidance control the over two-thirds of it was combined with the liquid oxygen tank and the alcohol tank and there was two pumps each pump would pump the fuel at the correct mixture and would dump it into the combustion chamber where it was ignited and and then the the compression of that going through the venturi created a significant amount of thrust enough to to launch the rocket and the guidance system on the v2 was a very simple approach they just used a compass heading that they would aim toward London and once they got and based upon the amount of fuel that they put into it would determine the range so once the v2 took off and arced over it would basically fly until it reached Apogee and where the engines shut off and ran out of fuel and then it would fall to earth and it wasn't very accurate but it was enough that they created a lot of devastation and and havoc within London the guidance system based upon a compass heading was controlled by two different rudder systems one was on the fins and the other one was right by the nozzle so the fins is something were more typically like on an airplane aileron or rudder the but the ones that was coming out it was kind of a novel approach at the time was that the they actually put a rudder within the thrust of the rocket engine itself and so as the blast was coming out through there they could adjust it and that would had a quicker response time than it would be with the the rudders that were located on the fins but by far the defends give most of stability to any rocket as I just mentioned about the v2 rocket and how they determine the trajectory where was going to land the the German engineers actually use a slide rule like this is a replica one that was actually taken one that was found at the pen and Monday Army Research Center in Germany basically the the German engineers would would set upon the amount of fuel that they will be loading up on the rocket on here and by adjusting the slide rule they would actually be able to determine what the range down downrange where the rocket would land within a very close approximation and I'm not too sure if that was 50 kilometers or or 100 but generally they weren't that accurate as far as where they fell
