Some have suggested that the shutter speed of the camera created the illusion of a stationary rotor, but I don't buy that at all. It is clearly not spinning.

I too have to agree with the shutter speed. The helicopter is maneuvering and that means it is in control and to control the Hind, the rotors need to be running. Thats one huge baby.
Wait for Honza Urban's reply, he has experience with the Hind, he could give some good insights.

One of the first things that should send up a red flag is the main rotor is not turning but the tail rotor is. Since these are connected that would be a problem, at least in every helicopter I have flown and I have flown everything from a Bell-47 to a CH 47. I like the camera theory explained by some of the others

hi man, the helicopter is Mi 24 and much like any other helicopter it is NOT able to fly without main rotor turning. the ilusion made by the frames per rate of the camera is clearly the only answer.
btw it is our Czech cammo
hind wing prodfuces some 30 percent of lift when flying forward speed of 300 km per hour
when hovering the wing is useless.
it is not able to "vector" the exhaust gasses. the turboprop engines are not suited for using the energy of exhaust gases.
the vectoring ilke nozzles are the EVU hot and cold air blenders designed to lower the IR significance of hot engines for the IR seekers fo MANPADS
watch the initial right tight turn - a maneuver consuming power - it usually decreases the RPM of the rotor - and alas the rotor turns a litlle bit countercolckwise - thats because the sinchronisation between shutter and RPM is gone.
the rotor of this helicopter turns some 250 rpm CLOCKWISE
thus small movement clockwise in this movie means the RPM quicker than shutter and counterclockwise is slower than sampling rate.
I still remember the 1st May Rwd square parades broadcasted in TV, where the SCUD trucks wheels were turning opposite the reasonable rotation :)

I watched it very carefully a few times and I just don't buy the shutter speed idea. You can still see the tail rotor turning, and it turns much faster than the main rotor. Also, the main rotor is perfectly motionless in relation to the fuselage and is clearly visible. No shutter speed could possibly make that perfectly constantly. But what is happening in the video is quite simply impossible. The Hind is a helicopter, it does not fly by jet propulsion and does not possess thrust vectoring.
There's something else involved here. Personally I'd guess it was an illusion using a model or something like that.

The camera has a very high shutter speed and is in sync with the rotor blades.
You can see the same effect in this movie of a plane taking off.

Single engine takeoffs are not allowed.

Regardless of the shutter speed, a helicopter cannot fly without the rotor spinning. It would be comparable to a Cessna Citation flying without wings. It just ain't gonna happen.
Someone doctored the video.

IT IS the shutter speed.
If the engine quit, the helicopter would autorotate. As it is descending the blades are still being spun by the wind. The pilot pulls the collective and cushions the landing. There is usually an auto rotation speed just as there is a Glide speed in an airplane. The main thing is that if it was autorotating the blades would still spin. So either you buy it or not, that IS THE ANSWER!

NO helicopter can fly with its main rotor stationary. The rotor appears to be still here as the rate at which the camera captures an image is equal to the number of revolutions per second of the rotor blades, so they give the illusion of being stationary.
translation: blades fast so fast they look like they are not moving.

ain;t no way it will stay in the air without spinning this is a picture shot at a high speed shutter

Considering that it is a Russian helo, I think the amazing part is that it is flying PERIOD.
The Muj must have missed that one...
