The landing gear, also called the undercarriage, is the primary support for an aircraft when it's parked, taking off, taxiing, or landing. It's designed to absorb and dissipate the kinetic energy of landing impact, reducing the impact loads transmitted to the airframe. Landing gear consists of a complex system that includes: Structural members, Hydraulics, Energy absorption components, Brakes, Wheels, Tires, Steering devices, Retracting mechanisms. The most common type of landing gear is wheels, but airplanes can also have floats for water operations or skis for landing on snow. The...

The most common type of landing gear is wheels, but airplanes can also have floats for water operations or skis for landing on snow. The metallic parts of the landing gear are made from high strength, high toughness, and corrosion resistant steels such as 300M/S155, AerMet® 100, Alloy 13-8, and Alloy 17-4. Each gear assembly includes the strut assembly (inner and outer cylinders), drag braces/side struts, and hydraulic actuators to extend and retract the gears.
