Aircraft Landing Gear Definition

Aircraft landing gear gears are special gears in mechanical transmission systems used to control the landing, takeoff and parking positions of aircraft such as airplanes and helicopters. These gears support the efficient operation of the mechanisms that provide opening and closing of the landing gear, steering of the wheels and shock absorption during landing.

Duties of Landing Gear Gears

✔ Ensuring the Opening and Closing of the Landing Gear → It enables the landing gear to move by working with hydraulic or electric motors.
✔ Impact and Weight Distribution → It balances the forces formed during landing and reduces vibration.
✔ Wheel Steering and Braking → It ensures the controlled movement of the aircraft on the runway.
✔ Emergency Mechanism → It supports the manual opening mechanism in case of hydraulic or electrical system failures.

Landing Gear Gear Types

⚙ Helical Gears → Provides high torque transfer and silent operation.

⚙ Bevel Gears → Used to change the direction of movement, especially in opening and closing mechanisms.

⚙ Planetary Gears → Provides precise movement and high torque thanks to its compact structure.

⚙ Worm Gears → Used especially in height adjustment and locking mechanisms.

Areas of Use in Aircraft

Commercial Passenger Aircraft → Provides safe landing with strong and durable landing gear systems.

Helicopters → Has special landing gear mechanisms to land at low speed.
Military and Cargo Aircraft → Contains high-strength gear systems suitable for harsh weather conditions.
Unmanned Aerial Vehicles (UAV/Drone) → Equipped with lightweight and compact gear mechanisms.
