摘　　要：引入和定义了必要的风场特征参数和工程化模型 ,建立了计及任意变化风场的无人机运动方程。以某型无人机为例 ,进行了数值仿真计算 ,并给出了切变风场和微下冲气流同无风情况起飞特性仿真时间历程比较曲线 。In this paper, the general motion equation of the unmanned aircraft with consideration of arbitrary variable wind field are outlined and derived, after the necessary characteristics parameters and the engineering models of the variable wind field are introduced and defined. A numerical simulation of unmanned aircraft is completed. The aerodynamic effects of the wind shear and its influence on unmanned aircraft launch process are discussed in detail.
