Abstract: The leak of Liquid Rocket Engine (LRE) is very common and dangerous.It is important to research a fast and effective approach for leak detection.In accordance to the measured monitor state parameters of LRE,the AR model is established and the time series analysis is completed.K-L information distance is taken as discriminant function to detect the leak fault of LRE.The simulation results show the leak fault detection algorithm is feasible.-
