Abstract: The purpose of this paper is directed against tests of liquid propellant englnes. All kindof testing failures in engines designed independently by China were counted, classified andsummaried. Referring to the current situations in measured parameters in testing and different failuretyPes, the test methods were made and the failure analysis modes were determined. If the modes areaccounted in engine testing, it is turned off in time when failures are occurred once. ln this way,engine damages and pmpllant consumption will be as less as possible if failure is take place.

Key words: Liquid propellant rocket engines;Failure detection;Failure analysis
