摘要

根据新一代液体火箭发动机特点,建立系统主要组件的动态数学模型。考虑推进剂的低温特性,对发动机的起动过程进行了仿真研究,计算方法采用龙格-库塔法。仿真结果表明数学模型合理,从而为判断系统能否稳定工作提供依据。同时也为发动机设计、改进和试验提供一定的指导意义。

Abstract

According to the new-developed liquid rocket engine feature,the dynamic mathematic model of main system component was built.Considering low temperature characteristics of the propellant,the start process of the engine was researched.The method of characteristics and classical Runge-Kutta was adopted for system model.Result shows that the model is reasonable,and provides criterion for judging whether the system can work steadily,and can be a guide for design,improvement and experiment.

Key words： liquid propellant rocket engine; start; dynamics; simulatio
