摘　　要：根据传统机翼气动外形设计的方案,结合CAD与CFD软件,本文提出了一套机翼气动外形设计流程,包括翼型选择、机翼平面参数确定、建立三维机翼外形模型、流场网格划分和典型飞行条件下的气动计算等多个部分。依据该流程,完成了一个满足设计指标的无人机大展弦比机翼外形的设计,充分说明了该机翼气动外形设计流程的技术可行性。A new wing shape design process is proposed based on the traditional wing shape design process and the use of commercial software CAD and CFD.The design process includes airfoil selection,determining the planar parameters of wing shape,designing three-dimensional wing shape model,grid generation and aerodynamic computation in a typical flight condition.A high aspect ratio wing shape of UAV designed based on the new design process meets to all the design requirements.It shows that the new design process is feasible,available and worth considering.
