| 摘 要： | 建立了液体火箭发动机稳态故障数学模型，编制了实用计算程序。调整方程组中的有关系数的参数，该模型既可用于在正常工况下评定性能参数随干扰因素的随机变化，进行发动机静态特性仿真。又可用于在故障状态下发动机性能参数衰减退化的计算，进行发动机稳态故障效应的仿真。

| Abstract: | This paper presents a steady fault analysis model of a liquid rocket engine, which involves various disturbing factors and fault statuses affecting main performances of liquid rocket engine. By adjusting some coefficients or parameters in the model equation, the model can be used for engine steady fault simulation under a normal engine condition. The paper presents main simulation calculation method and results of fault simulation. |
