Propeller


In space and astronautical engineering, a propeller is a device that converts rotational motion into thrust. Propellers are commonly used in aircraft and spacecraft to provide propulsion by accelerating a fluid, such as air or gas. In space, propellers are used to adjust the attitude and position of spacecraft, as well as to provide small amounts of thrust for trajectory corrections. Propellers can be powered by electric motors, chemical reactions, or nuclear reactions, depending on the application. The design of a propeller is critical to its performance, and factors such as blade shape, number of blades, and rotational speed must be carefully considered to optimize efficiency and minimize noise and vibration.
