Helicopter Rotor Gear Definition

Helicopter rotor gears are special gear systems that transmit engine power to the main rotor and tail rotor, providing balanced and controlled flight in the air. These gears are designed to operate at high speed and high torque and must be light, durable and low friction.

Functions of Helicopter Rotor Gears

✔ Transferring Engine Power to the Main Rotor → Provides the necessary lift force for flight.

✔ Transmitting Power to the Tail Rotor → Provides directional control by preventing the helicopter from rotating.

✔ Providing Speed ​​and Torque Control → Increases stability by adapting to different flight conditions.

✔ Reducing Vibration and Noise → Provides a quieter and smoother flight.

Helicopter Rotor Gear Types

⚙ Bevel Gears → Directs engine power to the main rotor at a 90° angle.

⚙ Helical Gears → Provides quieter and more efficient torque transmission.

⚙ Planetary Gears → Provides high torque and precise speed control with its compact structure.

⚙ Hypoid Gears → Specially designed angled gears to transmit power to the main rotor and tail rotor.

Areas of Use of Helicopter Rotor Gears

Main Rotor Transmission Systems → Allows the main propellers to rotate.
Tail Rotor Gears → Operates the tail rotor to maintain orientation and balance.
Torque Balancing Mechanisms → Provides precise power distribution to prevent sudden turns of the helicopter.
Military and Civil Aviation → Specially produced light and strong gears are used in military and commercial helicopters.
