摘　　要：以某泵压式供应系统的液体火箭发动机作为研究对象， 进行泄漏故障状态下的模拟， 为提取泄漏故障模式、优化监控参数、泄漏故障检测和诊断奠定了基础。仿真的结果表明，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
