Parametric Geometry Model for Multidisciplinary Design Optimization of Tailless Supersonic Aircraft

This paper presents an extension of the Kulfan Class Shape Transformation (CST) method for the parameterization of aircraft component geometry. The VT-CST code represents a practical implementation of the CST method in an object oriented C++ framework for use within a Multidisciplinary Design Optimization of a tailless supersonic aircraft. Extensions to the method 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, and control surfaces, among others. Examples demonstrating the utility of the method are given.
