AERODYNAMIC FORCES OF ELLIPTIC-CONE DERIVED WAVERIDERS AT HYPERSONIC VELOCITIES

The aerodynamic data for two kinds of elliptic-cone derived waveriders are presented and analyzed for a wide range of Mach numbers and angle s of attack. The basic shapes of the waveriders are obtained by means of hypersonic small-disturbance theory. Various off-design performance s of the waveriders as well as on-design performances are obtained and fully discussed. These aerodynamic data are informative for the desig n of hypersonic airplanes which are being investigated as future plane s. Also from the entropy distributions across the shock layers for ell iptic-cones and waveriders, the vortical layer is analyzed and discuss ed.
