摘　　要：建立精确的民航发动机性能模型有利于高逼真度的飞行仿真。基于Matlab/Simulink平台,依照CCAR-60对发动机的建模要求,分别建立了针对CFM-56发动机的推力、低压/高压转子转速、排气温度等模型。提出推力等级预设法,通过预设6个典型推力等级,更贴合民航飞行的实际情况,在保证动态性能的同时提高了模型的逼真度。最后,运用飞机着陆的真实环境和操纵数据对模型进行了验证,效果良好。The establishment of accurate civil aviation jet engine performance model could greatly improve the fidelity of flight simulator. Based on the Matlab/Simulink platform and the modeling requirements of jet engine in CCAR-60, the engine thrust, low/high pressure rotor speed and exhaust gas temperature model are built individually. The method of Thrust-rating presetting is proposed and by which, six typical thrust-ratings are preset to improve the model fidelity while keeping the real-time perform. In the end, the model is validated with real flight data of approach and landing. The results Show that the model is reliable.
