부하-강도 분석을 이용한 격막형 펄스분리장치의 내열강도에 대한 신뢰성 예측 사례연구

A stress-strength analysis is used to assess the reliability of a multi-pulse rocket motor system. Main stress is found to be thermal during explosion and the distribution is obtained by simulation. The strength distribution is derived from the results of actual specimen tests. The failure rate of barrier type pulse separation device is estimated.
