【Abstract】 The waverider shape to be used as a forebody on a airframe/engine integrated hypersonic vehicle is generated by a hypersonic flow round a wedge cone body.The lower surface of the waverider is created by trailing the stream line surface from the inlet plane until it intersects to the conic shock.Being an basic research,the design technique of airframe/engine integration bas been concerned.The surface pressure experiment has been done in a hypersonic wind tunnel.The results of experiment and computation show that the ratio of lift to drag( L/D =3 5)is good and the pre compressive ability of the foredody can satisfy the requirement of the inlet,So the configuration presented has a good future for scramjet engine vehicle.更多还原
