Do you mean like the one in Captain America? When the guy with the red face gets away from the burning factory? I have always wanted to build one of those.
Rocket motors that spin too fast for too long have a nasty habit of burning through the outside of the motor casing.
My question is the Composite lift motors. They are not very far from the center, but do you see the burning out the side affect on the liners of these when you disassemble them? How are the cases holding up?
Is it possible this beast coulg fly on 2xH motors, like the H54 or H90?
Do you think the structure could handle a G138T?
Being spin stabilized, CP/CG is largely not relevant on a rocket like this.
Spin can be important, but on an oddroc with much lower Cd. On a saucer the CP is behind the base of the rocket due to massive drag. On a design like this I'd venture to say it's some of both. For my L2 I was asked how to prove that the rocket was stable, and I showed them these pictures from Art Applewhite. https://artapplewhite.com/cp.html
A generic shaped saucer of x sides will always be stable upon liftoff
That is some fantastic workmanship!
A couple of times it came down pretty close to the pad. Are you worried that it might end up getting speared on the launch rod?
