| Abstract: | The leak of liquid rocket engine(LRE)is the most common fault.A nonlinear mathematical leak fault model has been established.The transient performance simulation has been performed under every leak fault conditions.It lays the foundation for further study on the choice of leak fault modes,optimizing the parameters of fault monitor and leak detection and diagnosis based on the model.The results show that the numerical method can simulate effectively the transient performance of the leak faults,and can simulate the leak fault in real time |
