论文部分内容阅读
本文第一部分简介了固体火箭发动机的贮存和综合环境试验,提出了主要的贮存和环境试验设备,以及主要的测试仪器等。第二部分介绍了固体火箭发动机的使用寿命预估方法。早期采用长期监测计划预估发动机寿命,后来改进为长期使用寿命分析计划预估发动机寿命,该计划包括破坏模式分析、过载试验、破坏概率分布和老化试验四方面的内容。最后得出了几点结论。
The first part of this article introduces the storage and comprehensive environmental testing of solid rocket motors, and presents the main storage and environmental testing equipment, as well as the main test equipment. The second part introduces the method of estimating the service life of solid rocket motor. Early use of long-term monitoring plans to predict engine life and later improvements to long-term life-cycle analysis of projected engine life including failure mode analysis, overload test, failure probability distribution and aging test four aspects. Finally come to a few conclusions.
