| Abstract: |
| The working mechanism of dynamic seal and the leakage failure of sealing system were discussed according to the structure of a missile turbojet engine. The development of the sealing units, fitting tolerance design and simulation bench tests of a special dynamic sealing system used in a missile turbojet engine were completed, and its wear mechanism was clarified. Test results showed that the structure design is correct. |
