摘要
以四氧化二氮/偏二甲肼(N2O4/UDMH)双组元挤压式推进系统为研究对象,对该系统的启动过程动态特性进行了分析和研究,运用单元法建立了整个推进系统启动过程动态数学模型,采用MATLAB软件中的SIMULINK工具仿真了推进系统启动过程,并得到发动机各阀门打开时序变化对系统启动特性影响的规律。
This paper focused on the investigation on the startup dynamic characteristics of the N204/UDMH bipropellant pressure-fed propulsion system, by use of the Unit method, the startup dynamic mathematical model of the whole propulsion system is presented, then the propulsion system startup process is simulated by using MATLAB/SIMULINK software, and the law of the effects of valve timing on the startup characteristics is obtained.
