Abstract: Fatigue is one of the key factors affecting the performance of aircraft in research or service. In this article, firstly, the aeronautical accidents caused by fatigue were quoted as clues to state the evolution of structural strength design concept and research situation at each specific period. Meanwhile, international aeronautical fatigue research and their significant development as well as the future developing directions in areas since 21 century has been reviewed and evaluated in the aspects of structural long-life design, fatigue analysis approaches and tools, full-scale structural fatigue testing technology, structural health monitoring and life extension of aging aircraft. Conclusively, considering the current problems and potential development directions, the challenges resisting the realization of high requirement on the long life, lightweight and high reliability of future aircraft design were pointed out on four topics:aeronautical fatigue on evaluation basic research, design and application research, testing evaluation and digital technology, which provides technical materials for the development of aeronautical fatigue.

Key words: aeronautical fatigue, structural integrity, long-life design, fatigue analysis approaches, full-scale structural fatigue test
