摘　　要：无人机机翼的气动特性关系到无人机的飞行性能,常规设计采用经验设计并注重风洞试验。本文采用计算流体力学软件对某型无人机机翼的三维外部流场进行模拟,得到了机翼三维气动特性。对数值结果与实验结果进行了比较分析,说明所采用的模型和方法能够正确地模拟机翼外部的复杂流动特征,为机翼的设计和改进奠定了基础。The 3D aerodynamic characteristics, as an important part in the performance of unmanned vehicle is obtained by the numerical simulation of 3D turbulence flow field over an airfoil of unmanned vehicle. The numerical results were compared with the corresponding experiment data, which showed that the conclusion in the paper was reliable.
