Multiple Choice

What is considered the hub of the tail rotor?

The hub of the tail rotor is essentially a 90° gearbox. This component is crucial for transferring the engine's power to the tail rotor blades while changing the direction of the drive shaft from horizontal to vertical. It allows the tail rotor to rotate and thereby provides the necessary anti-torque and directional control for the helicopter. The design of this gearbox is critical as it must handle the high rotational speeds and loads imposed during flight. By using a 90° gearbox, engineers can effectively manage the alignment of the rotor system with the overall helicopter's configuration, ensuring optimal performance and stability. This component plays a pivotal role in maintaining the balance and maneuverability of the helicopter, making it a fundamental aspect of the tail rotor system. Other components like the engine mount, transmission assembly, and pylon structure serve different functions within the helicopter's architecture and do not directly constitute the hub of the tail rotor system.
