AFOQT - Aviation Information (Helicopters) Exam Questions and Answers

AFOQT - Aviation Information (Helicopters) Exam Questions and Answers Mast/Shaft - CORRECT ️️ long cylindrical component that extends vertically from the main rotor transmission up to the main rotor hub. responsible for the rotational drive force that turns the main rotor hub. blade grips - CORRECT ️️ connect the rotor blades to the rotor system. allows the rotor blades to feather. Feathering is a term used to describe the change of the blades' angle relative to their rotation plane (also known as the angle of attack) pitch horn/ yoke - CORRECT ️️ Extends perpendicular to the main rotor blades. It connects directly to the blade grips and stabilizer bar and receives control inputs from the pitch links. Its job is to collect input from the pilot and translate that input into force, moving the blade grips. This force feathers the blades, or changes their angle if attack Flybar/stabilizer bar - CORRECT ️️ helps maintain a constant plane of rotation for the rotor blades teeter hinge/ trunnion - CORRECT ️️ connects the mast to the main rotor hub. allows the rotor hub and blades to flap up and down depending on control input and aerodynamic forces. when one blade rises, this allows the opposite blade to fall in its plane of rotation Swashplate - CORRECT ️️ mounted to the transmission and allows directional control
