| 摘 要： | 在传统的旋翼、尾桨、机身的气动力模型基础上,引入了缩比直升机的舵机、航向控制系统模型,建立了适合缩比直升机飞行控制系统设计的非线性飞行动力学数学模型。深入探讨了稳定杆对缩比直升机飞行动力学的影响,并进行了仿真计算,结果表明所建立的数学模型能反映缩比直升机的飞行动力学特点,适合其飞行控制系统设计。

| Abstract: | In this paper,the flight dynamics model of a scaled helicopter was developed for its flight control system synthesis.The aerodynamics models of the rotor,fuselage and tail rotor were established firstly,and then servos and its yaw control system model were developed.Stabilizer bar was an important component for scaled helicopter operation;its effect on the model was researched in this paper.The result shows that the flight dynamics model is suited for scaled helicopter control system design. |
