Abstract : the technical background , the current status and existing problems of the same subject both at home and abroad in the research field of the calendar life of the military aircraft were presented
文摘:介绍了军用飞机日历寿命研究的技术背景和国内外同类研究概况以及存在的问题。
Several key problems and their technical settlements were expounded emphatically , such as the accelerated corrosion test technique for aircraft structure under laboratory conditions , the evaluation technique for corrosion damage of anticorrosive coats , the distribution characteristics and their variation regularities of the corrosion damage and fatigue life , the corrosion equivalent relationship between the accelerated environment and the service environment , and the methods for theoretical analysis of the calendar life
重点对腐蚀环境下飞机结构加速腐蚀试验技术、防腐涂层腐蚀损伤评定技术、腐蚀损伤和疲劳寿命的分布特性及其变化规律、腐蚀当量关系和日历寿命理论分析方法等几个关键问题及其技术途径进行了阐述和探讨。
