Impellers
In space and astronautical engineering, impellers are rotating components used to increase the pressure and flow of fluids, such as propellants or coolants, in a spacecraft's propulsion or thermal control systems. Impellers can be designed in various shapes and sizes, such as axial, radial, or mixed flow, depending on the specific application and performance requirements. They are typically driven by electric motors or gas turbines and can operate at high speeds and temperatures. Impellers play a critical role in the overall efficiency and reliability of a spacecraft's propulsion and thermal control systems.
