| 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. |
