In order to analyze the impact of component performance deviation on the transient performance of a low bypass ratio mixed turbofan engine, the acceleration and deceleration process of the engine are calculated based on a turbofan engine model, combined with the Monte Carlo method and component performance deviation model. The distribution rules of key parameters during engine transient process caused by component performance deviations are obtained, and the key parameters affected during the engine transient process are analyzed. The results show that during acceleration process, the surge margin of compressor should be noticed to prevent the surge due to component deviation, while the risk of over temperature and rich extinction should also be noticed. The conclusions can provide support for the design of engine control laws.
