Design of wave rider based on shock fitting method

Abstract

Design of wave rider is attracting more and more attention right now and is of special interest for hypersonic applications. The article imports Shock Fitting Methods to calculate the three dimensional hypersonic flow to capture shock wave precisely. The choice of shock generating body is very important, because it affects the shock flow field. It can be single-stage or multiply-stage. In this paper, the double-cone shock generating body is introduced in order to modify lift/drag and the center of pressure of wave rider. According to the restriction of ratio of length to width, the shock surface is cut and then the outer line of wave-riding surface is decided. Relying on engineering application, the leeward surface is designed. The results show that lift/drag of engineering wave rider is relatively higher than ordinary vehicle.
