| Abstract: | 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 f... |
