摘要/Abstract

摘要：

基于某航空公司CFM56-7B 发动机高压涡轮转叶前缘历史孔探数据，首先分析热障涂层失效原因，运用统计分析方法，确定高压涡轮转叶前缘涂层脱落失效分布模型；然后对高压涡轮转叶前缘损伤发展趋势进行回归分析并计算机队高压涡轮转叶前缘平均寿命。

关键词: CFM56-7B 发动机, 高压涡轮叶片, 热障涂层, 失效分析, 损伤发展趋势, 平均寿命

Abstract:

Datum about one airlines'CFM56-7B engine fleet containing borescope inspection information about high pressure turbine are used to analyze failure reasons of thermal barrier coatings. Statistical analyzing method is employed to determine the failure distribution model. Regression analysis is then conducted to obtain the damage development trend of leading edge of blade. Finally, average life expectancy of leading edge of blade is computed.

Key words: CFM56-7Bengine, high-pressure turbine blade, TBCs, failure analysis, damage development trend, average life
