Abstract
A generic aerospace vehicle is constituted of three parts: a forebody, a scramjet, and an afterbody. This paper is concerned with the design of the forebody and the inlet by means of waverider configurations. Hypersonic stream surfaces past a cone with combined transverse and longitudinal curvature are used to design integrated inlets for wavenders. By suitably choosing a second-order even polynomial stream surface, inlet shapes can be controlled. Mass flow rate, wetted surface area, volume, lift, drag, and liftto-drag ratio can be found in closed forms. Effects of various parameters on the shape of the inlet are found and discussed in detail. Thus, an overall aerodynamic design of a hypersonic vehicle can be established in a simple and systematic way. Flight conditions are determined for a wide range of shapes and parameters as well as other related factors depending on the designer's interest.
