In order to develop an aerodynamic design and prediction method that combines the high lift-to-drag ratio of waverider and the high volumetric efficiency of lifting vehicle
research was carried out in three aspects. Based on fusion design concept of lifting vehicle and waverider
a hypersonic waverider design method with large volumetric efficiency and high lift-drag ratio was proposed. Numerical simulation was carried out to obtain the influence of typical design parameters on the aerodynamic performance
such as the volumetric efficiency and lift-drag ratio. Based on the proper orthogonal decomposition method and radial basis function
a rapid prediction model of hypersonic waverider flow field and aerodynamic performance was established and the rapid prediction of flow field was studied. The research showed that compared with ordinary waverider
when the height was 5 and 10 mm
the volume increased by 8.00% and 15.00%; the rapid prediction method based on the proper orthogonal decomposition method can accurately and quickly obtain the flow field of waverider with different design parameters and the prediction error was not higher than 2.00%.
