It is quite unlikely you would recover from fully established vortex ring state, as you lose control of the entire wing surface, therefore any cyclic or collective input has no effect. VRS comes from extremely poor handling and spacial awareness and 'incipient vortex ring' develops first. This is evident from increasing vibration and rate of descent. The best practice to exit incipient VRS is to lower the collective and nose forward to get the air flow over the disc again. Once above 30 kts ish, apply power and fly away. Doesnt look like this demonstration was remotely approaching VRS or even incipient VRS, which when developed will give a rate of descent of up to 8000' per minute. To get into VRS you need low air speed, typically less than 30 kts, high rod and then pwr applied. So much nonsense on you tube.

Now you just got to do it with bubbles.

Fully-developed vortex ring state due to the helicopter decending into its own downwash. Pilot esacaped by flying the helicopter to the left, ino clean air. This is called the "Vuichard Manoevre".

Amazing, thank you for creating this

Double curl

the beauty of fluid dynamics

Indeed a cool video to observe the vortex,,rotor enthusiast

Great video! Puts everything into perspective!

Was this a helicopter intentionally putting itself into a vortex ring state in order to demonstrate the Vuichard recovery technique?

I’m just an interested layman, not a pilot :)
