引进先进战斗机延寿取得重大突破的主要技术途径——耐久性修理是重新赋予飞机生命的修理

The Main Technology Approach that Foreign Aircraft Life Extension Obtained Important Develop——The Durability Repair that Confer Afresh Life of Aircraft

对引进先进战斗机延寿工作背景和复杂性进行了论述,通过对外方定寿各个环节的分析研究,针对性地采取了一系列创新的技术措施,及时地发现主承力结构的疲劳薄弱环节,并通过耐久性修理提高了飞机结构的抗疲劳品质,使飞机延寿工作取得重大进展。

This paper describes the background and complexity aircraft. According to the analysis of every factor of foreign of aircraft life extension of foreign work, we undertake a series of innovative measures and detect the key fatigue situs of main structural in time, The quality of resisting fatigue of structural is enhanced by durability repair and the fatigue life of aircraft obtaines an important advance.
