NASA Tests Flying Airbag 118
coondoggie writes "NASA is looking to reduce the deadly impact of helicopter crashes on their pilots and passengers with what the agency calls a high-tech honeycomb airbag known as a deployable energy absorber. So in order to test out its technology NASA dropped a small helicopter from a height of 35 feet to see whether its deployable energy absorber, made up of an expandable honeycomb cushion, could handle the stress. The test crash hit the ground at about 54MPH at a 33 degree angle, what NASA called a relatively severe helicopter crash."

The more spectacular helicopter crashes happen this way, but loss of power events are more common. The most severe of these occur at low altitudes as there isn't enough time to successfully autorotate. So this type of device should improve survivability in the most common crash/hard landing scenarios.

If you're flying too slow and low to the ground, there is less time to recover and perform an autorotation. In a heli's flight envelope, this is often referred to as the dead man's curve [wikipedia.org].
