What Is a Turbopump?
Turbopump (TP for short) is a power pump, which is the heart of a rocket engine. It consists of two parts, the turbine part and the pump part. The two are usually directly connected, and the pump is driven by a turbine. Turbine drivers are generally gas produced by combustion (which can be solid fuel or liquid fuel), gas-hydrogen (liquid-hydrogen-liquid-oxygen expansion cycle engine), and liquid-phase driven.

- Turbine pump is a linkage device for boosting the liquid propulsion unit-oxidant and fuel by a turbine-driven pump. The high temperature and high pressure gas from the gas generator is used as the working medium to drive the turbine to rotate to drive the rotation of the pump. Therefore, the oxidant and fuel from the storage tank are pressurized by the pump and then supplied to the thrust chamber.
- The turbo pump is a high-speed rotating component in a liquid rocket engine. At the same time, the high-temperature and high-pressure gas entering the turbine and the cryogenic propellant pressurized by the pump. With the increase of pressure, the reliability of the turbo pump plays an important role in the reliability of the entire engine. About half of engine failures occur in turbopumps. Therefore, the turbo pump is required to meet the reliability requirements of engine distribution under all operating conditions of the re-engine. At the same time, to ensure that the liquid rocket engine has a smaller size and mass, the turbo pump device should have a smaller size and mass.
