The Osculating Method Of The Dual Waverider Geometry Generation

The near space vehicle of the hypersonic glide-cruise dual waverider is a new type of vehicle for the new ballistic flight of glide-cruise and its aerodynamic layout design is one of the crucial development aspects in the realm of aerospace technology of the 21 st century.Based on summing up others' design experience,this paper presents following researches.Firstly,this paper studies cone derived method and osculating cone method,which are used to design waveriders.In order to verify the design methods,Cart3 d software is used to analyse the design performance and off-design performance about waveriders.Secondly,the basic aspects and design ideas of the hypersonic glide-cruise dual waverider are presented.In fact,glide-cruise dual waverider is a kind of hypersonic vehile which can change waverider surface to ride wave under two different Mach number.On the basic of the parameterized design,this paper establishs the basic design theory of the osculating cone dual waverider and the variable shock angle oculating cone dual waverider,succeeds in achieving these design ideas,and writes sets of shape generation programs.The numerical methods are utilized to verify the proposed design methods of the aerodynamic configuration in the design condition.The last not the least,this paper presents a new way to design glide-cruise dual waverider vehicle and succeeds in designing one hypersonic aerodynamic layout which has waverider wings.Generally speaking,this paper establishs two new design methods to generate glide-cruise dual waverider and a new way to design dual waverider vehicle.The calculation results show that the established design method and the dual waverider vehicle can meet the overall design indicators of the glide-cruise flight.
