Flywheels
In space and astronautical engineering, flywheels are mechanical devices used for energy storage and attitude control of spacecraft. They consist of a spinning rotor that stores kinetic energy, which can be used to power spacecraft systems or adjust the spacecraft's orientation. Flywheels are particularly useful for attitude control because they can provide precise and rapid adjustments without the need for propellant. They are also used as a backup power source in case of a primary power system failure. Flywheels can be made of various materials, including steel, carbon fiber, and composites, and can spin at speeds up to tens of thousands of revolutions per minute.
