| 摘要: |
| 以凝胶推进剂空间推进系统为研究对象，对该系统异常工作的动态性能进行了分析和研究。为了获得空间推进系统故障模式，把空间推进系统工作过程的故障特性方程与其正常数学模型相结合，采用Visual C++ 编程工具对导管泄漏故障、过滤网阻塞故障、电磁阀故障和喷管烧蚀故障进行了模拟，从而为空间推进系统智能化故障诊断奠定了基础。 |

| Abstract: |
| The dynamic characteristics in the abnormal operation process of the gelled propellant space power system is dealt with in this paper. For the purpose of setting up the fault patterns of the space power system, the fault property equations and the normal mathematical models in the operation process were built. Then, four faults, including pipeline leak, filter jam, valve fault and nozzle ablation, were simulated by the visual C++ software. With an analysis of the results, some foundation for the intelligent fault diagnosis of the space power system in the future is provided. |
