Spline-based waverider configuration optimization method

The waverider is a kind of hypersonic aircraft component in hot research.A spline-based aerodynamic configuration design method is introduced to build the waverider.And an optimal design based on the aerodynamic performance is also be studied under the given conditions and constraints using the previous technique.In this research,2 design cases generating from a conical fluid and a blunt body fluid respectively are demonstrated.In order to validate the accuracy of the design results,the CFD based numerical simulation is performed.It can be concluded that the spline-based aerodynamic configuration design method is quite feasible and the output of it can be used to the manufacture of the waverider model.
