飞机结构日历寿命及腐蚀防护研究应关注的问题

摘要

Service life system of aircraft was introduced. The service environment and service life of typical aircrafts were elaborated. The corrosion cases of typical aircraft structures were listed, and the causes of corrosion failure were analyzed. Based on the comprehensive analysis of the corrosion and calendar life questions of aircraft in our country, it was concluded that corrosion is the main damage mode led to aircraft structural failure and is also the main factor seriously affecting flight safety and economic repair of aircraft. Some focal point questions of calendar life and corrosion protection of aircraft structures were discussed.%介绍了飞机寿命体系，阐述了典型飞机服役环境和飞机使用寿命情况。列举了典型飞机结构的腐蚀实例，并剖析了腐蚀失效的原因。在综合分析当前我国飞机面临的腐蚀和日历寿命主要问题的基础上，阐明腐蚀是引起飞机结构失效的主要损伤模式，也是严重影响飞机飞行安全和经济修理的主要因素，探讨了飞机结构日历寿命及腐蚀防护研究应重点关注的一些问题。
