This post is an offshoot from the Goex BP thread. This is a recovery system I just test flew successfully at BALLS 29. Everything is in the nosecone, integrated altimeter board, gps, apogee "pushrod" and main chute line cutter. For apogee a tiny 1/8 gram charge of BP (or Pyrodex, or smokeless power) pushes a pushrod (not shown in pictures below) against a shelf in the airframe to push off the nose cone. Attached to the linecutter is the main chute in a drawstring bag which is released when it fires. Also only uses about 1/8g of gas generating powder. Powder is contained in both cases, will work in space.
