Abstract: To obtain the shape parameter effect on the aerodynamic performance of osculating cone(OC) waverider,based on the study of OC waverider characteristics and generation method,the design process was parameterized and orthogonal experiment was introduced to analyze each control parameter effect on the performance of OC waverider.The parameters that greatly influence OC waverider performance were determined,which can be used to determine the optimized design space and optimization strategy appropriately.CFD tool is used to analyze the aerodynamic performance of waverider configuration.Results show that the configuration can offer not only high L/D ratio but also the uniform flow field at the lower surface which can be used in the design of airframe/engine integration.As an example,an air-breathing,OC waverider based hypersonic vehicle was designed to illustrate the rationality of design method.
