| Abstract: |
| Objective To study effect of seal combination on structural seal performance. Method Sealing performance test was carried out to have experimental study from three combinations of the seal form, assembly form and coating form, to find out the influencing factors of structural sealing performance and the optimal combination of screening seals. Results Three forms of structural seals are sealed form: with or without face seal, assembly form interferential assembly, wet assembly, coating forms of partially coated and fully coated. Test of sealing performance of 8 seal combinations under two stress levels were carried out. Under ensuring the sealing process quality, selecting correct sealing combination according to the structure and loading characteristics of the aircraft could effectively improve the structural sealing performance. Conclusion In case of high stress and infrequently disassembled parts of the aircraft, the sealing combination, interferential assembly and partially coated sealing combination should be selected. In the aircraft structure design requiring gap assembly, fit surface seal, wet assembly, and partially coated seal combination is selected for often disassembled seal parts. |
