电动泵压式发动机系统方案与性能评估
System scheme and performance evaluation of an engine fed by electric pump
摘要
Abstract
A system scheme of liquid rocket engine fed by electric pump is put forward.A program for engine performance evaluation is compiled,which could be used to predict the specific impulse of the engine and quality of each component under the conditions of given thrust,mixing ratio and combustion chamber pressure.The research results show that the engine fed by electric pump is suitable for the upper stage engine with long working hours,has a critical time point relevant to combustion chamber pressure, and its cycle mass is lighter than that of gas generator when working time is greater than the point.The e-lectric-pump feed system always has the mass performance advantage when combustion chamber pressure is higher than 2 MPa and working time is longer than 317 s.关键词
