Landing gear is a system consisting of wheels, tires, suspension, and other support structures installed on an aircraft or air vehicle to enable safe takeoff, landing, and ground operations. Its main function is to support the weight of the aircraft when it is on the runway, as well as providing stability and control during takeoff and landing.
In general, landing gear consists of several components, including:
Wheels and Tires: These are the parts that actually come into contact with the runway or surface when the plane takes off or lands. These tires are usually made from special materials that are wear-resistant and can withstand high pressure.
Suspension System: The suspension in the landing gear functions to absorb shock and vibration when the plane lands or when it experiences turbulence. This helps prevent structural damage to the aircraft.
Supporting Structure: Landing gear also includes a strong supporting structure and is specifically designed to support the weight of the aircraft while on the ground. This structure must also be designed to withstand the pressure generated during takeoff and landing.
The landing gear system can usually be retracted or pulled into the fuselage when in flight to reduce aerodynamic drag. When landing or when airborne, this landing gear will be released again to provide support to the aircraft.
Because of its importance in aviation safety, landing gear must be regularly maintained and thoroughly inspected to ensure that its components are functioning properly before and after each flight.
