- 摘要:
- 针对液体火箭发动机试验中紧急关机关键过程进行了深入研究,简述了当前氢氧火箭发动机试验紧急关机的常用模式和方法,对影响自动紧急关机条件判读响应时间的因素进行了理论分析和实验验证,获得了在用紧急关机系统的响应时间指标.针对紧急关机存在的时间延迟问题,提出了缩短条件判读响应时间的途径和具体解决方法.该方法在实际的试验系统中进行了多次验证,程序的正确性和稳定性得到了考核.对大型数据采集及故障诊断系统响应时间分析提供一定的参考依据.
- 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.
