Do the blades on a helicopter spin clock wise or counter clock-wise?

Question

Do the blades on a helicopter spin clock wise or counter clock-wise if you are looking from the ground at the blades?

Answer 1

Depends on your perspective, all helicopter blades spin both clock wise and counter clock wise, depending on if you are looking from above or below the blades.

Answer 2

On the chinook one blades turn clock wise and the counter clock wise.

Answer 3

It depends on the make and model of the helicopter. In general, American made helicopters spin counter-clockwise when looked at from above (it's an arbitrary convention, but we usually talk about them as if viewed from above, not the ground). European and Russian helicopters typically spin clockwise when viewed from above. Helicopters with two main rotors have each one spin in opposite directions so there is no need for a tail rotor to provide antitorque.

There is no advantage for the main rotor to spin one way or the other. It's just the convention of the manufacturers.

Answer 4

depends on the make of the helicopter.

All russian ones are rotating counter clockwise /when using your view from groun upwards.... the pilot sees the blades moving from left to right ahead of him.

the Western ones are mostly designed the other way.
