Other AbstractThe aerodynamic characteristics of waverider under equilibrium gas condition have been studied by computational fluid dynamics(CFD) method, and the results have been compared with that under perfect gas condition. The analysis reveals equilibrium gas effects on aerodynamics of waverider are due to the decrease of induced pressure of boundary layer, which is caused by the chemical reaction in the boundary layer. In comparison with the angle of attack, equilibrium gas affects little on lift to drag ratio and pitching moment coefficients of waverider, but it has some effects on the pressure center, and the effects are different from that on the reentry vehicle. The results are valuable for the design of gliders based on waverider.
