摘要
针对液体火箭发动机可靠性设计问题，提出综合运用可靠性模块分析、故障模式及效应分析（FMEA）、故障数据分析及故障树分析（FTA）等可靠性分析方法，评估发动机不同设计方案的可靠性水平。此法可应用于方案论证阶段的发动机可靠性设计，并举例对某型号发动机的方案论证进行了典型分析计算。
A synthetic analysis on design reliability of liquid rocket engine is presented. Arigorous yet practicable approach for evaluating engine reliability during the conceptual study phase isput forward. The approach uses the proven reliability methods of reliability modeling analysis, FailureModes and Effects Analysis (FMEA), failure data analysis and Fault Tree Analysis (FTA) to estimatethe probability of mission success at the vehicle level for different engine designs. An example isprovided, in which the approach is used to evaluate a engine design concept
