Helicopter Tail Rotor Gearbox Components
The 350A33-1091-00 Gear Set is a key drivetrain component within the Tail Gearbox (TGB) of Airbus AS350 and H125 helicopters. This precision-matched gear assembly is designed to transfer mechanical power from the tail rotor driveshaft into the tail rotor output system. Built to withstand high torque and rotational speeds, it ensures efficient and reliable tail rotor operation under all flight conditions. The gear set is manufactured to OEM specifications to support long service life and consistent performance.
Functions:
- Transfers power within the tail rotor gearbox for directional control
- Supports rotational movement of the tail rotor shaft
- Ensures proper gear alignment and torque handling
- Operates under high-load, high-speed flight conditions
- Enables reliable anti-torque control during all phases of flight
Applications:
The 350A33-1091-00 Gear Set is installed in the Tail Rotor Gearbox of Airbus AS350 series helicopters, including the H125. It is essential for applications requiring precise yaw control and mechanical reliability, such as EMS operations, aerial firefighting, law enforcement, utility lifting, and passenger transport missions in diverse environments.
