针对现在液体火箭发动机的任务可靠度验证方案不考虑开、关机的影响或试验时间较长的问题,利用权重系数模型,综合了典型的利用二项分布和利用威布尔分布分别制定出的可靠性验证试验方案,提出了制定液体火箭发动机可靠性验证方案的方法.该方法可以在既考虑了发动机的持续时间的验证又兼顾了开机和关机过程的前提下制定出液体火箭发动机可靠性验证试验方案.所制定的方案利用了研制信息,节省可靠性验证试验的时间和费用.
In view of the fact that the task reliability verification scheme of liquid rocket engine now does not consider the influence of on and off or the long test time, the weight coefficient model is used to synthesize the reliability of typical use of binomial distribution and Weibull distribution Verify the experimental plan and put forward the method to establish the reliability test scheme of the liquid rocket engine.The method can make the test scheme of the reliability test of the liquid rocket engine not only considering the duration of the engine but also the starting and shutdown process The developed solution leverages development information to save time and money on reliability verification tests.
