摘要
针对发动机的故障特点，提出了其工作状态过渡的非线性动态数学模型。利用随机模拟结果，对发动机的故障特性进行了简单分析。还应用主成分分析方法。
A nonlinear dynamic mathematical model for describing the transient processes of working conditions has been established according to the fault characteristics in a liquid rocket engine.The fault performances have been simply analyzed on the basis of the random simulation results.Moreover,the fault isolatiability in the numerical simulation and the fault detectability in the real test have been simply discussed using the main principal analyzing method.
