The aerodynamic shape of the hypersonic glide vehicle (HGV) has become a research topic nowadays due to its excellent aerodynamic performances. Some limitations need to be reduced when the free-form deformation (FFD) method is applied to parametric modeling and design of an HGV. In this paper. a typical lifting body is considered as an example. https://www.nacrack.com/quick-grab-Chainsaw-File-super-grab/
