Question

The tail rotor is a smaller rotor mounted so that it rotates vertically or near-vertically at the end of the tail of a traditional single-rotor helicopter (Links to an external site.). The pitch of the tail rotor blades can be adjustable by the pilot to control what?

Answer 1

The pilot can control the rotation of the helicopter's body by adjusting the pitch of the tail rotor blades.

Step-by-step explanation:

The pitch of the tail rotor blades of a helicopter can be adjustable by the pilot to control the rotation of the helicopter's body. According to Newton's third law of motion, for every action, there is an equal and opposite reaction. When the tail rotor blades are adjusted to change their pitch, the reaction force generated by the tail rotor's rotation in one direction causes the helicopter's body to rotate in the opposite direction, thus preventing the helicopter from rotating in the opposite direction of its main lifting blades.
