Abstract: A analysis method of reliability growth for a certain solid rocket engine is performed.Based on the statistic data of reliability growth, the lowest value of the engine reliability is estimated with Bayes binomial distribution of reliability growth in stages. These results indicate that informations can be fully utilized and many samples can be saved by using this reliability growth method.
