A turbopump is a mechanical device that is used to deliver a high-pressure fluid, such as fuel, to a propulsion system, such as a rocket engine. A turbopump consists of a turbine, a pump, and a shaft that connects the two. The turbine is driven by a power source, such as a gas generator or a turbine engine, and the pump is used to pressurize the fluid and deliver it to the propulsion system.
Turbopumps are used in a variety of aerospace applications, including rocket engines, where they are used to deliver fuel and oxidizer to the combustion chamber. They are also used in some types of aircraft engines and in other propulsion systems, such as those used in spacecraft and missiles.
Turbopumps are critical components of many aerospace systems and are designed to operate at high speeds and under extreme conditions. They are typically built to be highly reliable and to withstand the demanding environments in which they operate.
