Rotor
In space and astronautical engineering, a rotor is a rotating part of a machine that is designed to produce a lift force or thrust. Rotors are commonly used in helicopters, quadcopters, and other types of aircraft that require vertical takeoff and landing capabilities. In space, rotors can be used for propulsion and maneuvering of spacecraft, particularly in low-gravity environments such as the Moon or Mars. Rotors can also be used for generating electricity in space, as they can be driven by solar or wind power. The design and construction of rotors in space and astronautical engineering involves considerations such as aerodynamics, materials science, and control systems.
