【 摘 要 】

In this paper, a fault tree model of certain rocket engine is established according to its structure and working principle. Through qualitative analysis and quantitative calculation, the factors affecting the reliability of a certain type of rocket engine are obtained, and the corresponding improvement measures are put forward to improve the reliability and safety of a certain type of rocket engine.
