NASA researchers dropped a small helicopter from 35 feet to see if a deployable energy absorber could lessen the destructive force of a crash.
Will be very use full for UAV auto landing.

Perhaps I am not seeing it, but how will this be really useful to UAV's when the primary purpose of the energy absorbers are to save lives in a crash? I can see that it might usefull to protect some equipment on board a UAV, but i think its abit overkill for UAV applications.

A lot of miniUAVs use inflatable baloons under their belly while landing.

UAVs that carry people can't be that far off no?

Then they wouldn't really be unmanned, would they.

Manned: Operated by, performed by.

So it would be unmanned as long as they don't pilot it.

Why didn't I think of this!!!! Strap cardboard boxes to the underside of helicopters......I could be a millionaire by now.....

be sure to use the special million dollar cardboard boxes.

seriously, probably not cardboard, must be something fancy that is airtight but allows air to vent controllably on impact. wonder if the pilot would get to have an oh sheet button to deploy it.
