Retractable Landing Gear
Retractable landing gear is a type of landing gear system that can be retracted into the structure of an aircraft or spacecraft after takeoff. This system is used to reduce drag and improve the aerodynamics of the vehicle during flight. Retractable landing gear is commonly used in spacecraft and high-speed aircraft, where the weight and drag of the landing gear can significantly impact performance. The system typically consists of wheels or struts that are mounted on a retractable mechanism, which is controlled by hydraulic or electric actuators. When the landing gear is retracted, the wheels or struts are stowed in a compartment within the vehicle's fuselage or wings. When the vehicle is ready to land, the landing gear is extended back into position.
