摘要
采用有限差分格式的特征线方法 ,对某姿控推进系统发动机真实推进剂管路在脉冲工作情况下的瞬变特性进行了数值研究 ,对影响发动机多次脉冲启动的重要参数进行了定量计算 ,对比分析了试验结果与计算结果的一致性。说明该方法可方便地对包括许多管路、阀门和推力室的复杂系统进行动态性能分析 。
By means of the finite difference scheme of characteristic method, the transient flows are simulated for the attitude control propulsion subsystem during the pulse operation. The effect of different conditions on dynamic behavior in pulse mode is investigated. The results are agreeable with the test process. The method can be used to analyze the dynamic performance of complex propulsion system consisting of numerous pipes, valves and thrusters. The results are valuable for designers.
