Turbines

In the context of space and astronautical engineering, turbines are devices that convert the kinetic energy of a fluid or gas into mechanical energy. Turbines are commonly used in rocket engines to power the pumps that circulate propellants through the engine. The most common type of turbine used in rocket engines is the turbopump, which consists of a turbine and a pump mounted on a common shaft. The turbine is driven by hot gases from the engine's combustion chamber, and the pump is used to circulate propellants through the engine. Turbines are also used in power generation systems on spacecraft, where they are used to convert the thermal energy of a radioisotope heat source into electrical energy.
