Abstract: |
In order to achieve effective seal of abnormal cavity whose sealing section contains acute angle, based on sealing test of ramjet engine inlet, different sealing sections of cavity, such as rectangular, trilateral and trapezoidal shapes were experimented and researched. An effective, stable and easly-operated sealing structure for above section was summarized. |
