摘要

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.

Abstract

The problem of liquid-propellant rocket engine's reliability compliance test plans at present is that ignoring the processes of firing and shutdown or the test taking too long.To solve this problem

considering typical compliance test plans of binomial distribution and Weibull distribution

using the weighting factors

the method of reliability compliance test plan developing was provided.The duration of firing was verified in this reliability compliance test plans developing method

at the same time the processes of firing and shutdowns were also considered.This reliability compliance test plan utilized development information and saved the test time and cost.
