In an American-made helicopter, applying left cyclic tilts the rotor disc to the left; at which part of the rotor disc will the highest blade pitch angle occur?

rear of the rotor disk front of the rotor disk left side of the rotor disk right side of the rotor disk

Correct Answer:

rear of the rotor disk

Explanation:

When you push left on the cyclic, the rotor disk tilts so the lift vector points to the left. The cyclic controls are phased around the blade’s azimuth so the angle of attack changes as each blade passes different positions. To produce a leftward lift while the disk is tilted, the blade in the rear portion of the disk is commanded to carry the greatest pitch, increasing lift there to support the left tilt. So, the blade at the rear of the rotor disk ends up with the highest pitch angle.
