Abstract: In this paper, according to the characteristics of the development of rocket motors and based on the development of some solid rocket motor, several structure reliability assessments commonly used at present in the reliability evaluation of mechanical products at home and abroad are adopted. With a large number of computations and by comparison, a more effective evaluation method is presented.
