How do the rotors turn on chinook copters?

Question

IS 1 cw and other ccw? --if yes, then why does this effect how it flies, how they turn in relation to each other?

Answer 1

Same direction, like an eggbeater.

From the pilot's seat they spin clockwise.

The forward rotor induces a counterclockwise torque moment.

The rear rotor induces a clockwise torque moment.

They cancel each other.

Since the rotors are on opposite ends of the mass they can turn in same direction yet create opposite torques.

Answer 2

Yes One does turn clockwise and the other Counter Clock wise.

This allows the rotors to cancle each other's torque, therefore there is no need for a tail rotor. This means all the power from the engine can be used for lift.

Another advantage is that Rotors can be shorter, allowing for greater ease in tight forest clearings. Also a Ramp can be fitted without the danger of a tail rotor chopping you to bits.

Answer 3

A helicopter needs something to couteract the rotational effect of the rotor ie: tail rotor. If you put 2 of them in opposite directions then that is taken care of. It is actually an effect of inertia. You won`t have to worry much longer , At the crash rates of those guppies they won`t be around much longer. Most of that problem is a simple matter of harmonics which all the specialist are to stupid to figure out. Counter rotating motors in a boat will eventually cause structural failure if they are not in sync. The vibrations will literally shake things apart

Answer 4

As most of the others said, yes, one goes clockwise and the other goes counter clockwise and they are synchronized, so they don't run in to each other over the body. One of the critical problems of gearbox failure is the blades running in to each other when they aren't synched any more... and down you go.

Answer 5

the front rotor is set slightly below the back, and they counteract the spinning effect
