| Abstract: |
| Objective To study the effect of service environment on aircraft structure.Methods The critical structure coupons of aircraft airframe were tested, and accelerated corrosion experiment was carried out based on the accelerated corrosion spectrum of a field airport environment. Test of fatigue after pre-corrosion was conducted using MTS810. ResultsThrough analysis of testing results, the relationship was determined, between the corrosion influencing factors of fatigue life and the corrosion damage size of aircraft airframe critical structure. Conclusion The result shows that there is a significant correlation between the corrosion damage width and the corrosion influencing factor of fatigue life of aircraft critical structure. |
