Helicopter Autorotation EC-120

Autorotations are used in helicopters to perform power off landings from altitude in the event of an engine failure. During an autorotation, the main rotor is not driven by a power plant, but by air flowing through the rotor disc bottom-up (imagine a windmill) while the aircraft is descending rapidly

Honestly the most beautiful auto i have ever seen. I don't care what any one negative says. Lots of people are just jealous because they are stuck in a 22 and have nothing else better to do than search you tube all day. Just sayin : )

@willabeast7 Thanks for the compliments!

Does this work on all helicopters???

[birddog36]

@hattrickster33 Yes it does!

@Emiel1111 dead man's curve, I know. I fly OH-58D's

[Emiel1111]

@mjm9536 You are right about the droop. About the airspeed though.... It is more a combination of airspeed and/or height. Zero airspeed at height, and you can still do an autorotation. But there is a Height Velocity Diagram for helicopters, and a shaded "avoid" area where you may not be able to perform a safe autorotation to the ground. So, as long as you have the height, it could come back. Either way, nice demonstration of an auorotation in this video.

Magnifique autorotation sur cet EC120 et très beau kiss après un Flair parfaitement exécuté.

Champion l'artiste.

Good lord, I'd shit me pants if I was flying a helicopter, engine OFF, seeing the ground come up that fast. THAT'S BALLS.

@willabeast7 Oof, I wish I was stuck in a 22 - I'm stuck just hoping one day I somehow manage to get enough money for a CPL!

[Samoflangee]

@willabeast7 Indeed something to aspire too, and i find myself stuck in a 22... and on you tube.

Awesome auto! I love doing these on my RC Heli's... Maybe someday a fullscale? :)

EC-120 is co-developed by China, France and Singapore in the mid-90s.
