Does it matter which way a helicopter rotor spin?

French or Russian helicopters tend to rotate in a clockwise direction. Those from the US and elsewhere generally rotate counterclockwise. A helicopter can be designed to have blades that rotate clockwise or counterclockwise.

What side is the tail rotor on a helicopter?

left
On counterclockwise main-rotor helicopters, pusher tail rotors are on the left side and the fin partially blocks the flow of air into the tail rotor. Puller or tractor tail rotors are on the right side of the fin; they draw in a clear flow of air, but have to push their outflow against and around the fin.

How do the blades of a helicopter rotate?

The blades are shaped like airfoils (airplane wings with a curved profile) so they generate lift as they spin. Each blade can swivel about a feathering hinge as it spins. Vertical pitch links push the blades up and down, making them swivel as they rotate.

When the rotor rotates in the anticlockwise direction when viewed from the stern and the ship steering to the left?

2. When the rotor rates in the anticlockwise direction, when viewed from the stern and the ship is steering to the left, then the effect of reactive gyroscopic couple will be to lower the bow and raise the stern.

When propeller rotates in clockwise direction and Aeroplane takes right turn?

The effect of gyroscopic couple on the aeroplane will be to raise the nose and dip of the tail. The engine of an aeroplane rotates in clockwise direction when seen from the tail end and the aeroplane takes a turn to the right. The effect of gyroscopic couple on the aeroplane will be to dip the nose and raise the tail.

Which part of the helicopter blades spin the fastest?

What this means for a main rotor blade is that when it is spinning the tip is moving much faster than the inner portion (root) of the blade. The longer the blade the faster the tip moves in relation to the root.
