Helicopter Flight Control

Question 1

Cyclic

Answer 1

The flight control of a helicopter in a forward, aft, left, or right direction by tilting plane path of the main rotor blades.

Question 2

Collective

Answer 2

The flight control of a helicopter to increase or decrease vertical lift by changing the angle of attack of all main rotor blades.

Question 3

Anti-Torque/ Directional

Answer 3

The flight control of a helicopter to turn the aircraft around its vertical axis (yaw) by changing the angle of attack of the tail rotor blades.

Question 4

Auto-Rotation

Answer 4

Turning the main rotor blades by the action of the relative wind rather than with engine power in order to make an emergency landing.

Question 5

Tail Rotor

Answer 5

Rotating airfoil that provides directional control of a helicopter by counter-acting the torque of the main rotor.

Question 6

Main Rotor

Answer 6

Rotating airfoil that provides the lift on a helicopter.

Question 7

Gyroscopic Precession

Answer 7

The resultant action or deflection of a spinning object when a force is applied to the object that occurs approximately 90° in the direction of rotation from the point where the force is applied.

Question 8

Swashplate

Answer 8

A component on a helicopter which changes the direction of the tilt of the main rotor disk. The lower part tilts on a gimbal but does not rotate, which also tilts the upper part that does rotate with the blades.
