A set of conceptual sketch for th e near-space high supersonic (Ma=3.5) unmanned aerial vehicle (UAV) is deri ved from the idea of integration of aerodynamic configuration and propulsion system . An accurate and straight-forward parametric geometry modeling for the near-s pa ce high supersonic UAV is essential to rapidly implement and evaluate th e conceptual design. A geometry parameterization method for accurate description of the UAV configuration is proposed by use of shape function/class function tr ansformation, Lagrange interpolation polynomial and B-spline curve. Based on th e geometry parameterization, a code written in visual basic (VB) language is deve loped through the creation of macros from the CATIA application, which is used t o implement the automatic generation of the 3-D geometry model of UAV. Thre e configurations of the high supersonic UAVs, including double swept wing, single swept wing and quasi-rhombus wing, are used to validate the method. The results show that ａｃｃｕｒａｔｅ 3-D geometry models for all the UAV configurations can be rapidly and automatically created by the VB code.
