Composites Landing Gear of an Airplane – Parts & Services
The landing gear of an airplane is a crucial component that supports the aircraft during takeoff, landing, and taxiing. It absorbs impact forces, provides braking capability, and enables maneuvering on the ground.
Main Parts of an Aircraft Landing Gear
Structural Components & Retraction System :
-
Shock Struts –Hydraulic or pneumatic components that absorb landing impact.
-
Torque Links / Scissor Links-Prevent excessive rotation and control wheel alignment.
-
Drag Brace & Side Brace- Provide structural stability and retractable movement.
-
Hydraulic Actuators – Control extension and retraction of
landing gear. -
Gear Doors – Cover the retracted gear to improve aerodynamics.
-
Uplocks & Downlocks – Secure landing gear in the extended or retracted position.
Wheel & Tire Components :
-
Wheels –Support aircraft weight and provide rolling capability.
-
Tires –Designed to withstand high loads and speeds, often reinforced with multiple layers.
-
Brakes – Disc brakes (carbon or steel) help slow down the
aircraft on landing.
Steering & Control :
-
Nose Wheel Steering System –Helps control aircraft direction on the ground.
-
Landing Gear Control Lever –Pilot-operated mechanism for gear deployment.
Landing Gear Services & Maintenance
