摘　　要：倾转旋翼无人机飞行力学模型是设计飞行控制律和分析飞行特性的基础。从一款在研的新构型倾转旋翼无人机工程实际出发,建立该无人机非线性飞行力学模型;分析新构型倾转旋翼机相比常规倾转旋翼机的特点和优势,建立直升机模式、倾转过渡模式和固定翼模式下各部件飞行力学模型;并针对直升机模式,对不同飞行速度进行配平及稳定性分析。结果表明:该构型倾转旋翼无人机直升机模式横航向模态具有很好的稳定性,直升机模式悬停状态横纵向模态基本没有耦合。The flight mechanical model of tilt-rotor UAV is the basis of designing flight control rate and analyzing flight characteristics.Based on the engineering reality,the nonlinear flight mechanics model of a new configuration tilt-rotor UAV is set up.Features and advantages of the new type rotor-craft are analyzed compared with the traditional tilt-rotor.The flight dynamics models of helicopter mode,conversion mode and airplane mode are developed.Based on the flight mechanics model,taking helicopter mode for example,trim and stability are analyzed for different flight speed.The calculate results show that,this configuration tilting rotor has good lateral and directional stability in helicopter mode.The lateral and longitudinal coupling of helicopter hover mode is nearly little.
