摘要: 

对某型退役飞机进行分解检查后发现其结构腐蚀十分严重,以某处不受力的铝合金结构为研究对象,进行细节结构的局部分解、清洗和检测;得到其腐蚀损伤尺寸、形态参数及其分布特性;基于统计分析获得的分布特性参数,考虑飞机结构实际服役过程中的随机性,建立服役环境条件下腐蚀损伤扩展的概率模型,经验证该模型可行。

关键词 铝合金孔蚀老旧飞机统计规律    
Abstract

A retired navy aircraft had serviced for more than twenty years in a southeast coastal airport, where the environment is high temperature, high humidity and high salt fog. The aircraft was torn down and then inspected, and it was found that its corrosion damage was serious. The aluminum structure was partly disassembled, clean and nondestructive inspected. The corrosion damage size, shape parameter and distribution characteristic were gained. Based on distribution parameter obtained through statistics analysis, a probabilistic model to predict corrosion damage growth under service environment was established, with considering of the randomness during corrosion process of aircraft structure. The results show that the theoretical model is very precise.
