Watched a program years ago on *shock loading of individuals in helo crashes.

They dropped some Hueys' with data link on the dummies.
the failure point on the spine to where bones crush..leg bones..hips.

Some solutions were forwarded...shock obsorber seats.

Have wondered myself..if an airbag type device mounted on the skirt or belly of a helo would not reduce the shock loading when the bird crashes.
If it works in cars..at least it could minimze injury in regards to helo's.

Having some form of control when a helo drops is possible..but eventually they they just impact and the kinnetic energy starts fracturing things.

Some may comment that the bags would rupture from bullets or fragments...

yes..but they have self sealing fuel tanks and bladders..and should be able to adapt that to an inflation device.

The Black Hawk compartments and landing gear are fitted with shock-absorbers to protect personnel in the event of crash landings.

I like your idea. I hope it gets some serious study among our helo manufacturers.

During the last half-year I was in Southeast Asia, I was detailed as a classified documents courier while recovering from some minor injuries, essentially a glorified special-delivery mailman. As a result, I rode military aircraft, including helocopters, a lot more than I liked, and had the experience of being a passenger during the crashes of two UH1 Hueys, a Southe Vietnamese H19 Kingbee, and a fixed-wing C7 Caribou, in varying degrees of seriousness. I was not real happy about being in any of the incidents, but any of the four could have been a whole lot worse. Anything that makes such rides a little safer is an improvement in my book, and if you care to offer any ideas toward that end, I'd be glad to consider them in the light of my own admittedly limited experience, but experience that did indeed make a lasting impression on me. We may not come up with anything new, but it can't hurt to try.

So use many, smaller bags, fitted with *one way* inflation bags, and dual inflation lines for doing so in the event one of the lines is ruptured or parted. Or instead of expanding each bag via pressurized air or gas, use an electrically-fired cartridge like an auto airbag's, but in a much smaller size.

Hueys were bad because of the forward/low seating of the pilots, who generally got shattered ankles and knees, sometimes thighbones as well, from the forces transmitted into their lower extremities via the rudder pedals when the aircraft hit the ground. You'd have to come up with some way of eliminating that problem for the pilots, but the passengers aboard might at least enjoy such protection. Funny the radios aboard get such swell shock-mounts, with built-in springs and snubbers, but the personnel aboard don't.

I don't think I'd care to find out if a Blackhawk crash is as interesting as one in a Huey. One reason I always liked catching courier rides in the OH-6 *Loach* was that I'd never gone down in one, though I supopose the odds would have caught up with me eventually.
