Abstract: With the development of space technology, the reliability of propulsion system isrequired more and more. Establishing an advanced system for condition monitoring and fault diagnosisis an important measurement to improve the test safety and working reliability of liquid rocketengine. In this paper, according to the development of an engineering application for ConditionMonitoring and Fault Dagnosis System(abbreviated as CMFDS)of YF-75 engine,it is emphasized tointroduce system function, system compeition and structrue, making up and interface of systemhardware,engine main technical condition,fault mode analysis,setting up fault libaries,selecting partsand parameters for monitoring, etc. In addition, the algorithms for condition monitoring and faultdiagnosis has also been deseribed in more detail. Finally,the results of testing CMFDS with the 18primary ground tests data of YF-75 engine are also given in this paper,which demonstrates that theCMFDS has very high adaptability and effectability.
