| Abstract: | 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. |
