Spectacular! Helicopter avoids a crash with the autorotation

Autorotation is a state of flight in which the main rotor system of a helicopter or other rotary-wing aircraft turns by the action of air moving up through the rotor, as with an autogyro, rather than engine power driving the rotor. The term autorotation dates to a period of early helicopter development between 1915 and 1920, and refers to the rotors turning without the engine. It is analogous to the gliding flight of a fixed-wing aircraft. (Font Wikipedia)

Let's be clear, he did not avoid a crash. That is a crash landing by all definitions. What he avoided was a catastrophic and potentially fatal crash.

I know that each chopper pilot is able to make an autorotation landing, but man this guy has huge balls! Respect!

[briantegeder]

I got to auto rotate in a CH46 when I was in the Marine Corps. It was just for training, but it was still pretty cool. Props to this person for saving it.

[gk]

Not just being able to perfectly execute an auto rotate and save the aircraft and its passengers without damage at all, but also picked the perfect spot and toughed down accurately. Almost seems like a training exercise.

[troygreen]

That's what I call coming in hot 🔥

[Deusmecumest]

Great piloting skills. It's just a few seconds, but the reaction time is just a fraction of a second. And having seen a deadly crash on that same type of bird, a fraction of a second can be too late.

[ianberry]

That's not an autorotation that saved a helicopter from crashing. He may have been practicing autos but he crashed. Engine was still running after the very hard landing.

[osumbuckeyenut]

He didn't AVOID anything!!! That was a CRASH... And it was not an engine failure, it was training.

I’ve done several auto’s and experience a full down with a 10k plus hour IP next to me, I wouldn’t call it beautiful. They’re alive and that’s a beautiful thing but to split the skids like that is a hard landing and then some, the pilot should have had enough air speed and positive rotor RPM to pull back on the cyclic and generate enough lift before doing a full down, if this was a training 180 auto then it should have been conducted as a power on recovery with no touch down to begin with. Looks to me like an oh shit decent possible communication error or not enough altitude or potentially something went wrong with the engine and rotor RPM’s causing decay during their decent, in any case they are alive and that’s a blessing to live to tell the story.

[fardmek]

That is an accident during TRAINING of autorotation! The pilots misdjuges the sinkrate and hit the ground too hard, simply a big miscalculation but they survive...

[omegahyperes]

I always thought helos would simply fall out of the sky without power. Nicely done!

[vladboguslavsky]

А это точно авторотация? Слышно что двигатели работают в штатном режиме.

Correct Video Title: "Spectacular! Helicopter crashes while attempting autorotation"
Here is what _actually_ happened:
The pilot was practicing auto-rotations, (i.e. "pretend" the engine had failed by dropping the throttle) with intent to either perform a soft, controlled landing, or increase throttle and lift back up into the air (power recovery). As the helicopter was descending too rapidly, he was unable to perform either of those options and, instead crashed onto the runway.

So, in short, he messed up big time.

[spankyharland]

one nice thing about helicopters is that if the engine fails or if your tail rotor goes out, you can autorotate back to earth, provided that the main rotor is still intact....but once you loose the main rotors your sleek helicopter has the aerodynamic characteristic of an anvil.

[gwfowler]

It is a practice 180 degree autorotation (the Army calls it an auto with turn). Looks like he was late getting the turn finished, which lead to starting the deceleration late/low, which lead to the crash. MD600 being a low inertia rotor system makes it critical to time it right.

[hrissan]

Всё вроде правильно - сначала раскрутил винт максимально за счёт быстрой потери высоты, потом увеличил угол атаки лопастей, и за счёт инерции винта уменьшил вертикальную скорость.

[joeblow]

Thats not autorotation but that is the most radical helicopter landing I have ever seen.

[visarma]

Full touchdown autos are a blast. In an emergency, I’d rather be in a helicopter than my twin airplane. I can land on a parking spot in a NTAR vs needing a country street, freeway, runway and 2, 800 feet of it, to walk away.

[ЮрийСалтыкарло]

Это не вертолёт изумительный а пилот - Мастер с стальными нервами.
