| Abstract: | The main purpose of this paper is to study the aerodynamic performance of cone-derived waverider with blunt leading edge in off-design regimes.Waverider was generated by solving three-dimensional viscous flow field.Using the upper base line of waverider as parametric modeling object,waveriders were parametrally designed and optimized.Waveriders were blunted by the improved Tincher method.The CFD was used to analyze the aerodynamic performance of the waverider with design Mach number of 6 and cruise altitude... |
