Greenback.... A Helicopter Recovery

This one has went through 7 different revisions to get to this point.

The rear fin can ejects and floats back to the ground on a chute, while the upper portion deploys (3) blades and spins back.

My only issue is how fast the helicopter blades will bring it down? They generate lift, so it has to be more than a quick area calculation of the blades compared to an equivalent area of a parachute.

I n any event I can't find a calculation for the decent. If you happen to know of one... hook me up.

 2024-11-12  I'd still like a calculation to determine lift and the resultant decent rate? 

I think this rocket is on hold, pending further data.​
