I got a lil storm going in my head. If any of you have heard of Cirrus aircraft; some of their planes have what is called CAPS ; Cirrus Airframe Parachute System. Their chute is deployed by a rocket. I'm thinking of building a system a lil simplier. My prototype will be on my spad debonair. I'm thinking a set of doors and with a flip of a switch; a servo opens up a sets doors, just aft of the CG and the rush of air pull a small chute which then pulls the main chute. I know I have some bugs;like the plane could be ripped in half by the force of the chute filling with air, lines could get intangled in the prop. I plan to use the system to make no damage on the plane. Cirrus says that they designed theirs to collapes the landing gear. I hope to save the entire plane; besides the damage that might have accoured before the chute is deployed like the wing is missing cause of a hard snap, etc Some might think I'm crazy; some think this idea is odd; I think I could have something here. Is there anything I'm missing, any suggestions. I plan to do some test with some homemade chute and some weights.
