| 摘 要： | 基于特征线法进行了双组元挤压式空间推进系统动态过程仿真方法的研究,提出了在动态过程仿真模型基础上建立和求解静态特性仿真模型的方法。编制了静动态特性仿真软件,通过对某空间推进系统进行的调整工况、模拟故障时的静动态特性仿真,验证了所提出的静动态特性仿真方法的可行性和实用性,该方法可以减少仿真所需的工作量。通过扩充元件库,能够对其它类型推进系统进行仿真。

| Abstract: | Based on the method of characteristics, a simulation method for dynamic process of bipropellant pressure-fed space propulsion system was studied. A method of building and evaluating static characteristics simulation model was presented and it was based on the dynamic process simulation model. By simulating the static and dynamic characteristic of one space propulsion system, the feasibility and practicability of this method was validated. It may reduce the workload by this method. By appending components in the software, other propulsion systems can be simulated. |
