Landing Gear Strut (Shock Absorber)
The landing gear system is an integral part of an aircraft, which aids in maneuvering, braking, shock absorption and acts as an undercarriage. The landing gear is the interface of an airplane to the ground so that all the ground loads are transmitted by it to the aircraft structure. The main functions of the landing gear are energy absorption at landing, braking, steering, and taxi control.
Without the landing gear, this energy wouldn’t be dissipated and would impact the airframe, damaging it with time. The shock absorber is basically a mechanical or hydraulic device designed to absorb and damp shock impulses. It does this by converting the kinetic energy of the shock into another form of energy (typically heat) which is then dissipated. In an aircraft, it is used for absorbing the vertical kinetic energy of airplanes at the instant of landing. The landing gear system includes: Shock absorber; Extraction/retraction mechanism; Brakes; Wheel; Tires; Links and braces; The landing gear system is similar to a quarter-car arrangement in an automobile, and consists of 3 main components as in mass, spring, and damper.
