摘要：
The key problem of calendar life in critical fatigue fighter parts lies in the lack of universal calendar life de⁃ sign methods. To solve this problem，we first discuss the influence of the environment during ground parking，low alti⁃ tude flight，and high altitude flight on the structural fatigue performance of fighters，based on the characteristics of fighter flight load. Secondly，a calendar life analysis model for the fighter structure is established based on the DFR method for durability design of fighter structures under corrosive conditions and the fatigue damage accumulation theory，and the influencing factors of the calendar life are analyzed from the perspective of service environment，air⁃ craft type，material and structure. Thirdly，the calendar life design method for critical fatigue fighter parts is established based on this model. Finally，the feasibility，universality and superiority of this method are illustrated by comparing with the traditional calendar life evaluation technology and an example of the calendar life design of the 2nd wall on the outer wing of a certain fighter. © 2023 AAAS Press of Chinese Society of Aeronautics and Astronautics.
