I have often pondered the idea many times. We all know were the danger is in helicopters its roughly 300 ft above ground and below thats were all the sneaky little single strands of wire live or little piece of plywood or tin that gets blown up into your rotor blades maybe even a fence post to the tail.Taking off to heavy and on and on. Having said that there are things that will kill you were a chute would work like someting breaking, flying into a 0 visability enviroment, rotor stall ,etc. In my mind the chute could be placed aft of the tail rotor there it would possibly clear the tail and main rotors.The nose would have to have a counter weight (ballast) because of this unsightly appendage stuck to your butt but it might just work. Money and the Faa approving such is the big limiting factors but it would be nice to have that extra comfort zone.

Today i talk with some friends about this subject and i search the internet about this thing and i found this site:) . I think as well to an system of parachutes above the propeller.we must make a rotor more thick , the propeller on this rotor and from inside to come out a set of 3-4 parachutes.
On point 2 , under the helicopter a big airbag and on point 3 a substance which one its pushed in the fuell tank.This substance make the fuell incombustible .This thinks connected on separated emergency system running on batterys.

I assume airbags would do better than a crumple mechanism.

“The company that makes these is RAFAEL and the name of their product is REAPS Rotorcraft External Airbag Protection Systems.”

what about an accordian like crumple mechanism designed to slow down impact up to 150ft freefall attached underneath landing gear using steps to get up in the r-22,and others… i would expect this to raise the cockpit above the ground and add some weight to the units weight and cost.A small price to pay if it were to save 1 human life.I dont know if this is feasible but I’m hoping someone a lot smarter than me would give this or any other idea that would make a power failure survivable.I lost my brother 4/13/06 his last day on duty protecting and serving the chelsea michigan community as their police chief.
