Parametric Geometry Model for Design Studies of Tailless Supersonic Aircraft

This paper presents an extension of the Kulfan class-shape transformation method for the parameterization of aircraft component geometry. The VT-CST code represents a practical implementation of the class-shape transformation method in an object-oriented C++ code for use within a multidisciplinary design optimization framework for design studies of a tailless supersonic aircraft. Extensions to the class-shape transformation method incorporated into VT-CST include the generation of a blended wing–fuselage, cowls and inlet ramps for embedded engines, automatic handling of centerline continuity, shape normalization and scaling, fuselage area-ruling capabilities, conical cambering, airfoil shape matching, and control surfaces, among others. Examples demonstrating the utility of the method are given.
