| Abstract: | A kind of anti-aircraft missile solid rocket motor with high length-diameter ratio was taken as the ob- ject of study, all kinds of load on the grain during the process of the missile rotary launching out of the con- tainer was analyzed in detail. By computing the stress-strain field of the grain, the danger part of the grain was found, and the cause of the combust chamber high pressure explosion was analyzed. |
