Second helicopter crash test

The second crash test of a small lightweight helicopter at NASA's Langley Research Center in Hampton, Va., was a smashing success, literally -- just as engineers had predicted.
The helicopter smacked hard into the concrete. Its skid gear collapsed, its windscreen cracked open and its occupants lurched forward violently, suffering potentially spine-crushing injuries according to internal data recorders. The crash test was all in the name of research to try to make helicopters safer.

Thanks all for commenting. The idea behind this crash test was that it replicated a relatively severe but potentially survivable crash. That takes into account auto-rotation. As one of our engineers said we could have dropped the helicopter from the top of the gantry, but then all we would have had were pieces to pick up .. but not much useful data.

That's another reason we do tests like these ... to improve the computer models.

Results are still being assessed, but the injuries to the dummies in this test were quite severe, possibly spine crushing or even fatal.

@vassdel Helicopter height was 35 feet. The flight path angle was about 33 degrees and the combined forward and vertical speeds were about 48 feet per second or 33 miles per hour. Have to doublecheck G forces and get back to you.

@thewaterfalloflove Good question. We have a call into one of our researchers and will hope to have an answer soon.

@MrBJC1996 Choose the first helicopter drop test with the deployable energy absorber - a lot more survivable!

@thatonebeone We did a previous crash test that tested an energy absorbing system sort of like an airbag, but a honeycomb cushion You can find it on the NASALANGLEY channel.

I fly a Robinson R-44 Raven I. The seats absorb energy as do the skids and I can tell you its a really nice helicopter to fly and with all the new safety systems, should do well in this crash test. How well I dont really know. I fly both Robbies and find them to have nice full down characteristics. No hard landigs should develop if auto's are done correctly or near correctly. Nice to see the NASA boys trying to improve the rotor community's safety. Thanks fella's.

I live across the river in Titusville. Have you also considered the hazard of rotor blade intrusion into the cockpit as this is also one of the most dangerous phenomenon from an uncontrolled touch down?

For those of you saying this isn't a realistic crash. Vortex Ring states could crash like this or if there's engine failure and the pilot doesn't autorotate properly it would fall that way.

the rotor have to be taken in too because the rotation and helicopter blades are like beyblades

The more safety features added the more the weight. In a fatal crash no amount of safety gear will help.

looks to me like they would have all died even in just a short fall, so imagine being up higher and unable to do auto-rotation.

It appeared the landing skid suspension was too soft. he seats did not start collapsing until the bottom of the heli hit the ground. The seats then collapsed quicker than they would have if the gear had been a bit stiffer. JMHO.

Idk if it’s the structure of the helicopter but it looks like the landing gear cushioned the fall

@MitsuomiTakayanagiEC 14 жыл бұрын

to add something to the system NASA are testing I feel that harnesses might be beneficial rather than the lap strap only plus it seems that the seats might benefit from a shock absorbing system as well as under the fuselage

Why don't equipped an Helicopter with a parachute and an expulsion rotor system to soft the impact?

@DarcyWhyte 14 жыл бұрын

@thatonebeone I think the airbag in front thing (like a car) isn't going to help. The strike is from the bottom (not he front like a car). I figure if the seats could elevate before impact and then give a longer cushion it might reduce injury. Or the landing struts. That seems like a no brainer. Why not have them take up more of the impact. Perhaps have them another foot longer and have them bring the speed down smoothly rather than just snap.

When was the last time you saw a helicopter crash like this?? Usually they have lost the rear rotor and are spinning like a frakking top in the air....at the same time they are dropping like a stone! Or, when they hit the ground, they fall sideways and the spinning rotors hit the ground throwing shit...and people....and people parts flying everywhere. Results of this test: all occupants, who once had 3' spinal columns, now have 12" spinal columns....OUCH!

At such a height and speed, it doesn't give much data. But as such, the helicopter isn't something you want to crash in that's for sure...

@MitsuomiTakayanagiEC 14 жыл бұрын

@X0Pete if the tail rotor gets damaged then this will happen for sure but the forces on impact should still be the same so there is no need for nasa to test it while adding spin to it plus it would make recording the results 100 times harder

Helicopters are impossible to eject from. But what if so made it so before you eject straight up, you make the blades release. Of course this is for like war. You can't release blades into a city lol.

@5959512 13 жыл бұрын

would a shock absorption system under the seats be helpful?

@dabneyoffermein595 8 ай бұрын

it would have to be a gel system and it would need to be very thick and very deep (top to bottom). There needs to be enough absorption to prevent the spinal injuries that were the result of this crash test (or presumably so). The spine is very brittle on the downward force. So get a tube of Pringles and drop them from ceiling height and make sure they land in a straight line 0% or do 33% like in this video using a fishing line to ensure in-line characteristics. Now, tell me what the chips look like, Yep, that's your spine.

ill be honest with you all,, i think the crash will be way more dangerous because if theyre really flying they have the propellers to worry about swinging verry violent and it all depends on how high theyre in the air but good wreck thoo...

WOULD ATTACHING SHOCKS FROM BOTTOM OF COPTER TO LOWER SKID HELP? REBOUND COULD BE CONTROLLED BY LOCKING SHOCKS TO ONLY ACCEPT IMPACT , NOT RECOIL IT . IT WOULD SAVE BREAKING OF HINGED SKIDS . AND THE FULL BODY IMPACT . RESULT. GIANFRANCO FRONZI SEPTEMBER /2/2011
