Ground resonance is a hazardous condition during touchdown or at other times when the helicopter is running while sitting on the ground. A series of shocks to the landing gear can pass through to the rotor disk and cause an imbalance in the rotor system. Under extreme conditions, the imbalance causes violent oscillations that quickly build and result in catastrophic damage of the entire airframe. While filming an episode for MacGyver this Gazelle helicopter pilot encountered the first symptoms of ground resonance and managed to recover from this potentially dangerous situation by taking off. During takeoff, the helicopters door opened in flight but the footage was kept and was aired in the episode.
The pilot of this Polish built Mil Mi-2 helicopter came in to land with a high rate of descent, stalling the helicopter close to the ground and as a result the helicopter bit the dust. Fortunately nobody was hurt.
My personal guess is this pilot didn’t really want for this maneuver to go the way it did. Of course, I am only saying this because the touch down seemed to be a little bit on the rough side, a look at the slow motion and you’ll understand… also I am wondering what were those passengers thinking after the touch down…
Don’t really know much about this one. This Puma helicopter seems to have a tail rotor failure sending it in an uncontrolled spin… that’s what generally happens when you lose the tail rotor. Hope everybody made it out alive…
It is always cool to try to impress your friends with some crazy low level stunts. They remain amazed at your courage and you will feel king of the skies. Of course you need to have the skills for such a demanding task, otherwise they’ll get the scare of a lifetime and you’ll finish the day on a hospital bed thinking what the hell possessed you to do such a crazy thing. So remember, doing crazy death spirals is cool only if you succeed in landing on your feet afterwards.
Don’t really know much about this one. All I can say is this guy is really funny. At first i thought it was going to be one of those lame cockpit videos (quite a lot of them out there) but at the end i was laughing so hard it almost hurt.
