Abstract: |
The research status of pulse separation device (PSD) in pulse solid rocket motor and it’s materials were reviewed in this paper. Introduced the design forms and materials of rigid PSD and soft PSD. The advantages and disadvantages of ceramic material one-way broken mode, jet rod mode, metal piece mode, resin soft mode, and rubber soft mode were explained. Analyzed the pressure capability and opening performance of various PSDs. Finally, some opinions on the future development trend of PSD and its materials were presented. |
