摘要
飞机老化使结构的强度及刚度降低 ,影响结构的使用功能 ,甚至直接影响飞机的飞行安全 .对导致飞机材料或结构老化原因的研究为飞机的修复和维护提供及时可靠的依据。好的修复和维护措施可以使飞机的实际使用寿命得以延长 ,节省维护过程的费用 .同时 ,对民航飞机而言飞机的特性还涉及乘客的舒适性和安全性 ,因此 ,对老化飞机的研究具有重大的社会和经济效益 .就飞机老化问题的国内外研究情况进行系统归纳回顾 。
Due to aging of aircraft the strength or stiffness of components will be reduced, the factors leads to aircraft aging and the methods to extend the service life of aging or damaged aircraft has been developed since 1970's. This paper summarizes the related problems about aging aircraft ,such as nondestructive testing/evaluation?damage repair technique?the use of smart materials/structure . By using a series of character of advanced composites, such as high strength ratio and stiffness ratio, the aging/ damaged component can be effectively repaired through adhesively bonded composite patches on it. The problems to be solved in the future are specially pointed out.
