摘要

为确定发动机薄弱环节

指导重复使用火箭发动机可靠性设计

以航天飞机主发动机为研究对象

通过模糊故障树分析法和因子化分析法对发动机主要组件的关键失效模式进行研究.结果表明:模糊故障树分析法给出关键重要度最高的底事件为由剥落、凹坑、磨损和腐蚀致高压氧化剂涡轮泵的轴承失效;因子化分析法通过考虑风险、时间和概率3种因素综合评估出发动机系统中的综合因子最高的失效模式为涡轮叶片失效.

Abstract

To confirm weak parts of engine and guide the reusable rocket engine reliability design

the key failure mode analysis of major components for space shuttle main engine (SSME) was conducted based on fuzzy fault tree analysis and factor analysis. The result show that the elementary event of highest critical importance is the bearing failure of high-pressure oxidizer turbine pump caused by flaking

pits

wear and corrosion

which is obtained by fuzzy fault tree analysis. The typical failure mode of highest comprehensive factor in engine system is turbine blade failure evaluated by considering risk time

and probability in factor analysis.
