摘要
Abstract
A geometric class function/shape function transformation technique is introduced, and it meets requirements of dimension and shape driven parametric geometry modeling of aircraft. The modeling method can give a brief representation of various shapes or configurations with fewer variables compared with traditional CAD and modeling method based on conic curves. Variation of dimensions or class function/shape function variables can get a family of parametric surfaces, and more shapes or configurations are obtained conveniently. The lifting-body and waverider configurations demonstrate that the method is simple, effective and versatile, and can be used in external shape optimization of conceptual design.关键词
