Optimization Design of High Lift to Drag Ratio Waverider Vehicle Based on Viscosity Simulation

Abstract

Based on the shock-fitting method, the optimization design of waverider is studied by introducing the influence of height. The numerical simulation results show that the blunted leading edge and the upper surface modification do not increase too much resistance, the viscous lift-to-drag ratio is still greater than 4.0, which opens a new way for the practical application of waverider vehicle.
