An innovation waverider design method: Osculating Curved Cone(OCC) method
Usually, waverider is produced by Osculating Cone(OC) method which is based on straight cone. A new method is put forward in present paper named Osculating Curved Cone(OCC) method which is based on general curved cone. The difference between OCC method and OC method is that OCC method using a general curved cone as the osculating flow filed. Detail design procedures of OCC method are introduced in present paper. OCC method uses general curved cone to design waverider, this makes sure mat the compression ability of the OCC waverider can be adjusted to fit the special requirements. The design results of OCC waverider show that OCC waverider has better flow uniformity and higher volumetric efficiency than OC waverider. The OCC waverider has high pressure recovery and lift to drag characteristics. Inviscid aerodynamic characteristics and flow field structures of the designed OCC waverider are simulated using Computational Fluid Dynamic(CFD) software AHL3D. The theoretical design results are compared with the CFD simulation results. The comparison between OCC waverider and OC waverider is also presented
