Navier-Stokes simulation for cone-derived waverider

The three-dimensional, laminar flowfield associated with conical waveriders, whose cross-plane lower surface is derived from an ellipse, has been analyzed in the present study by numerical simulation of the Navier-Stokes equations. The numerical method uses the flux difference splitting algorithm. Both Euler and viscous solutions have been obtained. Results of zero angle-of-attack and 5-deg angle-of-attack cases, respectively, are presented. The analysis to date has dealt with the forebody only. Surface pressure coefficients are compared with experimental data. Skin friction coefficients are calculated and lift and drag values are estimated. The skin friction, lift, and drag values are compared with previous analytic estimates and they are found to be in reasonably good agreement. The study provides valuable preliminary insight into the feasibility of using waverider configurations for aircraft design.
