16th AIAA/DLR/DGLR International Space Planes and Hypersonic Systems and Technologies Conferenc AIAA 2009-7423 Design of a Curved Cone Derived Waverider Forebody He Xuzhao† 1,2 Le Jialing ‡ 1,2 Wu Yingchuan § 1)China Aerodynamic Research and Development Center Mianyang China 621000 2) Northwestern Polytechnic University, Xi’an, China, 710072 Abstract 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 3 2 4 introduced in present paper. OCC method uses general curved cone to design 7 - 9 0 0 waverider, this makes sure that the compression ability of the OCC waverider can be 2 . 6 / 4 1 adjusted to fit the special requirements. The design results of OCC waverider show 5 2 . 0 1 that OCC waverider has better flow uniformity and higher volumetric efficiency than : I O OC waverider. The OCC waverider has hi
