It’s a sampling issue.  It’s like when you see the wheels on a car and they appear to be moving backwards on the highway. The choppers blades are moving at the right speed.

Either the velocity at which the camera is recording is the same as the velocity at which the blades are rotating, therefore the camera always records the blades at the same position, giving the ilusion that the blades are not moving.

The blades in the tail just rotate at a different velocity. You can also notice that they are moving very slow, which confirms that the camera is recording fast.

Yup - strobe effect - the blade rotational speed is synchronised with the camera frame rate.

Also...the rotors are bent upwards i.e..under strain.

If you look carefully, the main rotor blades move very slowly as the helicopter makes its turns, because for a fraction of a second, they are under extra strain, slow enough to be slightly out of synch with the frame rate.

That’s bullshit.  There has to be another explanation.  You’re telling me that in the history of recorded helicopter flight, this is the first time ever that “the blade rotational speed is synchronised with the camera frame rate?” I don’t think so.

i think its magic!

I think, its Chris Crocker making us leave Britney alone by suggesting flying helicopters without rotating rotors!

i think it’s a ship, not a heli. and ships don’t use rotors, do they?

The chopper uses thermal lift just like glider airplanes

I think its bill clinton cooking wishy washy mighty spicy meatballs!

idiots. this chopter is a quite old model, and theres no connection between camera record rate and blades. it seems like they stay still with bare eyes too. Its the rate of turns the blades do. and this is old news.

After reading these comments...I now think its being held up by invisible pixies…

what, you mean you can’t see the pixies?? 8O

de_bunk what is it with the pixies?! you been drinking acid?

It´s shutter speed rather than frame rate speed.
It must be well over 1/400th of a sec.
Nice clip

part of all advanced helicopter training involves shutting off the engine and surfing the thermal air pockets and all pilots must know how to do this. if your engine fails you wont be able to stop the fall but you may be able to slow the fall and not hit the ground as hard. outside the city in soft dirt or sand you may even live to tell the tale. in the city where the concrete does not give?good luck.

Autorotation (used for controlled descent in the event of power failure by exploiting natural aerodynamic forces) is what I believe you were referring to, and this is definitely not an example of it. The blades don’t cease to rotate, they just aren’t being rotated by the engine.

As others have said, it’s simply a strobe effect -
the rpm of the blades is close enough to the frame rate of the camera (or a harmonic of that rate) so that the blades have rotated, but appear to be at a very similar position to where they were in the previous frame. The effect is quite common, most cameras are simply too slow for it to be likely to happen with something moving at such a tremendous rate.

The main rotors are not moving .. just watch the rotor closest to the fuselage .. he is riding a strong (very strong) updraft just like hawks do

I’ve never seen anything like this before, pretty strange. Is it a camera trick?

There are TWO sets of blades. One is black and as we usually know them to be, but the other one is transparent and is over the black set. So the transparent one is doing all the work while the viewers are too busy watching the non rotating black part and wondering what the hell is going on.
hahaaaaa...next theory please....

It’s using V/STOL technology, like the Harrier jumpjet, because I can hear the sound of jets. Why the Russians would incorporate this tech on a helicopter is puzzling.

I blame badgers, especially Rangers supporting ones

Its a Gigantic Marionette operated by the hand of God - if you look REALLY closely you can see the strings!!

If you guys notice, you can see the rotar shadows on the fusilage turning as the ship turns.
So I kinda think that debunks the synchronised rotars answer.
Even still, if the rotars and camera were synced, you’d still see the outer edge of the rotars turning in a circle , not visible here.
Thermals? Maybe. Magic? Could be. Pixies?
Why not.

Only people who masturbate excessively can’t see the blades rotating.

Its being lifted by another chopper above it otherwise you wouldn’t be seein the roter on the tail cuz it spins 3 times faster then the main roter. And if its riding a thermal pocket or a strong up draft with the engine cutt why do u hear the blades chopping air. very simple explanation lol HAHA i just read eyepoppers theory lol u hear a jet engine cuz choppers that size do have turbine engines idiot

i think The Dude has got it. If you look when it turns it does look like its on the end of wire or whatever they would use

STROBOSCOPIC effect, so well known. basic

“STROBOSCOPIC” If its the strobe effect then tell me why do you see the shadow of the blades on the chopper??? its bein longlined by another chopper very simple

Ermmm.
Turn your volume up, you can clearly hear the blades. Like the guys said it a strobe effect with the camera.
All these bad vibes people. A tip for you..When you masturbate do it in a sock. You can then relax more and fall asleep and be nicer to people on forums.

Wow your an idiot avitor lol the chopper u can hear is the one above it that is longlinging the chopper below. theres no strobe effect other wise you wouldnt see the shadow of the blades on the chopper or you would not see the tail rotter at all because it spins three times faster then the main rotter.
And i dont need a sock i’ll just use your face lmao

I reckon it’s a scale model filled with helium. They’ve done it with cars - look real and they float in that same kind of way. Remote controlled with air jets trying to steer it. It’s probably a metre long.
The strobe effect theory ain’t bad, but when the whole thing turns toward and away from the camera, I’d have thought the doppler effect would have changed the perceived speed of the rotors, if only slightly enough to produce a haze. Sorry, can’t buy the strobe idea. Floaty scale model with dubbed sound. You know it.

Yeah its not a Strobe effect. If you look hard enough the Rotors will rotate the opposite direction. And I concur with the shadow theory, the blades shadows wouldn’t be that still let alone clear. Also there are no “invisable” Blades on a Bird. just in case you were being serious h89
