What component provides a mounting point for the tail rotor blades?

• A. Tail Rotor Blades
• B. Tail Rotor Head
• C. Anti-Torque Link
• D. Yaw Damper

Answer: (B)

The tail rotor head provides the mounting point for the blades. It’s the central hub that the blades bolt into and from which their pitch is controlled. The head sits on the tail drive shaft and contains the bearings and pitch-change mechanism that lets the blades tilt to generate thrust for countering torque. The blades themselves are mounted to this hub, so without the head there’d be no mounting point or means to change blade angle. The anti-torque link and yaw damper play supporting roles in the tail rotor system, but they don’t serve as the blade mounting hub.
