  • It's just a ground resonance test. Has nothing to do with rotors failing, cuz that's basicly hardly possible. You could have a main drive shaft failure and then the rotors would collide. But that's obviously not what's happening here.

  • ground Resonance !

  • Looks to me like the back rotor failed and threw the balance way off.

  • actually i beleive it is a ground resinance test,

  • i agree, its kkind of eerie with the lack of sounds :S

  • im a mechanical engineer but don't claim to be a heli expert but i think this was a demonstration of a failure of the main rotor, and perhaps what the secondary could do to "parachute" survivors.?
