摘　　要：发动机系统建模是飞行模拟器建模的重要组成部分,发动机模型的准确度直接影响了飞行模拟的逼真程度。首先研究了飞行模拟器发动机系统的建模方法,对分排气式双轴涡轮风扇发动机进行了建模,在与真实发动机特性进行比较的基础上对模型进行了修正,在飞行模拟器其他系统配合下进行了调试验证,得到了仿真结果。并对飞行模拟器建模所特有的故障设置和ATG试验的实现方法进行了讨论及仿真验证。Modeling of engine system plays an important part in the modeling process of flight simulators. The accuracy of the engine model affects the fidelity of flight simulation directly. Modeling techniques of flight simulator’s engine system were studied first .The model for dual shaft turbo-fan engine was developed and modified based on the difference between the computer model and the characteristics of the real engine .Debugs were made with the help of other flight simulator sub systems and results were retrieved .Ways to realize the malfunction effects and the ATG test were developed and verified by simulation.
