After years of hard-working, aircraft design philosophy evolved gradually from static strength to safe-life, and now to fatigue and structural integrity as a guide. Aircraft structural integrity program has been implemented successfully into structural development for several new types. The service life, reliability and economy of the new generation aircraft structure have been improved significantly. However, with the improvement of aeronautical technology and the development requirements for new aircrafts, many new problems emerged in this area. From the perspective of aeronautical industry, this paper combs the progress and main achievements of aeronautical fatigue research in China, and focuses on the research status and engineering applications in the aspects of material/structure/process, analysis and evaluation method, fatigue test technology and service life management since 2000. Finally, some aeronautical fatigue research directions need to be focused on were proposed in order to provide reference for the further development of domestic aeronautical structures.
