A STUDY OF THE OPTIMUM TRANSVERSAL CONTOUR OF A BODY AT HYPERSONIC SPEEDS USING DIRECT METHODS

Abstract

This paper refers to a slender conical body whose length and base area are given and considers the problem of determining the transversal contour which minimizes the overall drag (sum of the pressure drag and the friction drag) under the assumption that the pressure coefficient satisfies Newton's impact law and that he friction coefficient is constant. Direct methods are employed, and the analysis is confined to a body whose cross section is either a regular polygon or is compose of a basic circle external to which are symmetric segments of a logarithmic spiral.
