飞机结构日历寿命研究现状及关键问题

CURRENT STATUS AND DEVELOPMENT OF CALENDAR LIFE OF AIRCRAFT STRUCTURE

介绍了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。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。

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. 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 corrosion equivalent relationship between the accelerated environment and the service environment, and the methods for theoretical analysis of the calendar life.
