摘要
Abstract
Emergency shutdown key processes in liquid rocket engine test are studied in this paper.The current commonly-used modes and methods of emergency shutdown in the liquid rocket engine test are expounded.The factors influencing the condition interpretation response time of automatic emergency shutdown are analyzed in theory and verified in experiment.The response time indicators of the emergency shutdown system were obtained.In order to solve the delay time problem of emergency shutdown,the ways and concrete solutions to shorten the condition interpretation response time of emergency shutdown are put forward.The method was verified repeatedly in actual test system.The correctness and stability of the procedure are assessed,which provides a certain reference basis for large data acquisition and analysis of fault diagnosis system response time.关键词
