Does anyone know of any "rules" for tumble recovery boosters? Is there any online literature on this subject? I am designing a two stage rocket and I am wondering how to design the booster stage to fall without damage. Thanks!
Personally, if I were an RSO at the launch, I don't think I'd be comfortable with a 1.5 pound stage tumbling back to Earth. Also, depending on the aerodynamics, the booster stage could be stable in the opposite direction (tail-first) on decent.Good point. The booster stage will weight a little over 1.5 lbs. The motor is a G339N (I'm certified). The CP will be ahead of the CG or the booster after burn out. The fins are pretty big on this stage.
I guess I can put a chute in it. It is a 4" dia tube and would probably only need an 18" chute. It would probably get knocked out after seperation. There wouldn't be an ejection charge on the G339N.
