A Conceptual Design of Next Generation Hypersonic Air-breathing Airplanes with Dual Waveriders Forebody

Abstract

A design methodology employed for a practical preliminary-level integration of next generation hypersonic airplanes is presented in this paper. The key feature of this type of configurations is that the forebody of the vehicle is designed by rotating and assembling two waverider-based-surfaces, which are defined by linear edges. The propulsion system assumes two scramjets with cylindrical combustion chambers. The layout of the configuration presents a Blend-Wing-Body aircraft in order to integrate the airframe and the propulsion units as well as to improve the aerodynamic performance. Nomenclature
