- 摘要:
- 根据液氧煤油补燃循环发动机的特点，建立了稳态工作过程故障仿真数学模型，并针对比较典型的几种故障模式，进行了仿真计算与效应分析，最后进行了故障参数特征的初步提取。结果表明，选定的10个缓变热力参数，可对泄漏、堵塞及涡轮泵等典型故障模式进行有效识别和分离。
- Abstract:
- The simulation mathematical model of fault occurring in the steady-state working process is built and simulation software is designed according to the characteristics of LOX/kerosene staged combustion cycled rocket engine. Several typical failure modes are simulatively calculated. The effect of the fault is analyzed and characteristics of the fault modes are extracted. Ten slow variable thermal parameters were selected on the basis of the anaysis result to identify the faut modes of leakage and jamming in the fuel pipe of engine.
