摘　　要：高空长航时无人机是一种新型的无人飞行器,在战场侦察和高空大气探测等方面有其特殊的用途。根据无人机特点,构造了具有联接翼特征的飞机气动布局;通过总体建模、网格划分、数值计算并应用MATLAB软件编程仿真,分析了无人机升阻特性、纵向静稳定性和横航行静稳定性;计算结果表明此方案满足设计要求,可为大型无人机总体设计提供理论依据和技术支持。High-altitude long-endurance UAV is a new unmanned aerial vehicle. In battlefield reconnais- sance and high-altitude atmospheric sounding and so on has its special uses. According to the characteristic of UAV, joined-wing aerodynamic configuration is constructed. Through modeling, meshing, numerical calculation and Matlab software simulation, vortex lattice method is applied to analyze the UAV lift-drag characteristics, longitudinal static stability and lateral and directional static stability. The calculation resuits fulfill design objectives and which can provide theoretical basis for large-scale UAV conceptual and oreliminarv design.
