Aircraft Universal Joint Companion Flange

An aircraft universal joint companion flange is a component used in the drivetrain system of an aircraft. It is typically found in the propeller shaft assembly, connecting the engine to the propeller.

The universal joint companion flange is designed to transmit torque and rotational motion between two shafts that are not aligned with each other. It allows for flexibility and compensates for any misalignment or angular movement between the engine and the propeller.

The flange itself is a circular or square-shaped plate with bolt holes around its perimeter. It is typically made of high-strength materials such as steel or aluminum to withstand the forces and vibrations experienced during aircraft operation.

The universal joint companion flange is connected to the engine output shaft on one side and the propeller shaft on the other side. It is secured in place using bolts that pass through the bolt holes and are tightened to ensure a secure connection.

Overall, the aircraft universal joint companion flange plays a crucial role in maintaining the integrity and efficiency of the drivetrain system in an aircraft, allowing for smooth and reliable power transmission from the engine to the propeller.
