Name: turbopump features: turbopump is the most core component of rocket engine. It is actually a propellant pump, which consists of two parts: rotor power pump and driving gas turbine. These two components are installed on the same shaft and sometimes mesh together. The main purpose of turbopump is to produce high-pressure fluid, and then supply it to combustion chamber. The number of parts of 3D printing turbopump is 45% less than that of traditional turbopump, and the performance is greatly improved, so as to reduce the risk and cost of manufacturing rocket engine.
