| Abstract: |
| Objective To evaluate aircraft calendar life, and to determine the change rule of local parking coefficient with calendar years (C-T curve). Methods Targeting at the typical aircraft structural connector, precorrosion test with accelerated corrosion and fatigue test after precorrosion were conducted under laboratory conditions, and fatigue life in different equivalent corrosion duration was obtained. Then the fatigue test data was statistically analyzed. Results Fatigue test data was statistical processed and C-T curve was fitted. The determination of C-T curve establish the foundation of the aircraft calendar life evaluation. Conclusion The C-T curve can provide a basis for life determination of an aircraft. |
