【Abstract】 Reciprocating pump pressurization system is a new type of orbit attitude control engine self-pressurization system.Based on the working principles of the pressurization system,the dynamic model of thermal reciprocating pump and pressurization system are established.Then the system is simulated for starting characteristic and thermal performance of the reciprocating pump.Simulation results show that models can reflect pressurization transport process,which provides an important basis for the design of components and system.更多还原
