Magic Helicopter Flies Without Blades

topic:
Videos

Camera shutter speed synchronized with helicopter blade frequency When helicopter blades spin at an angle, they push air beneath them which creates lift. Sure, it's a simple way of looking at helicopters, but that's the basic premise.

What's amazing about this video is that the helicopter's rotor and blades hardly appear to be spinning at all and yet somehow it still manages to stay in the air. This is because the shutter speed on the camera (the amount of time the camera's sensor sees the image) has been set to the same speed that the blades rotate.

Trippy.

LOL.. Rotary wing without the rotation..

Helicopter Pilot 1: Trust in the Force, I do. Make helicopter levitate, I have done. To make it move, your job it is.
Helicopter Pilot 2: I will try.
Helicopter Pilot 1: Do or do not. There is no try.

That side, it's cool! XD

Helicopters do not fly by simply pushing air down. Each rotor blade is a wing that spins around the center axis. It generates lift by producing a lower pressure on the top than on the bottom, just like any airplane. The main difference is that a helicopter is suicidal and desperately wants to crash (requiring the pilot to be ever vigilant), while an airplane is generally well-adjusted and will do what it can to fly straight and level, given half a chance.
