摘　　要：以某型直升机飞行模拟器为背景,阐述了如何建立直升机旋翼系统的仿真数学模型。运用旋翼的空气动力学理论,分析了其中的技术要点,有针对性地讨论并设计了一种旋翼系统仿真模型的建模方法,其中根据直升机模拟器飞行动力学仿真的需要对旋翼系统模型进行了适当简化,降低了模型的复杂性。仿真结果表明该模型能够较逼真地模拟直升机的动态特性,实际应用效果验证了所述理论及方法的有效性。The simulation mathematics model of helicopter rotor was given based on a type helicopter simulator as the background. According to the theory of the rotor aerodynamics, the related technical key points were analyzed; and then a modeling method for rotor simulation model was discussed and designed pointedly. According to the needs of flight dynamics simulation for helicopter simulator, the mathematics model of rotor was simplified properly to depress its complexity. The simulation result shows that the model can simulate dynamic characteristic of helicopter realistically. The validity of the presented theory and method was validated by the application effect.
