| Abstract: | During the development of the rocket engine, the new engine is coming from the fault analysis and the removal of its predecessors. In this paper, the concept of equivalent test data is presented. Then, using the Bayesian method, with a few field test examples, the reliability of new products are evaluated. With the result of the stage reliability evaluation, the reliability growth of the system can be evaluated. A sample is given to illustrate the method. |

| Keywords: | Bayes method ML-II(Maximum Likehood-II) equivalent test data reliability growth |
