| Commercial software supporting hypersonic waverider modeling is relatively rare,and the support for functions expected by aerospace experts is not perfect,which is mainly listed as:(1)lack of interactive modeling support for ICC curves(Inlet Capture Curve)and FCT curves(Flow Capture Tube)in waverider modeling;(2)isolation of the integrated design process of 2D curves and 3D models;(3)weak real-time interaction support and lack of fine-grained curve modeling capability;(4)prone to discontinuities and irregularities in the flow surface during the design process.Based on the above requirements and limitations,this thesis designs and implements an integrated platform for interactive modeling of waverider,which main features are summarized as follows:(1)supporting an integrated modeling process for both 2D curve design and 3D model generating,acheiving the what you see is what you get effect;(2)supporting real-time interactive modeling of fine-grained 2D curves,and providing a variety of spline curve algorithms for 2D design curve ICC and FCT;(3)proposing the Curvature Radius Equalized Sampling Algorithm(CRESA),which enables the curvature radius interval to be uniformly distributed in the scenario of real-time interactive operation,solving the problem of irregular flow surface in modeling and design;(4)implementing cross-platform multi-layer architecture design,supporting various mainstream operating systems and hardware platforms.The thesis has realized an integrated software platform for interactive modeling of waverider,and obtained computer software copyright.The software has supported the scientific research and production practice of waverider design by experts in the aerospace field.And it is expected to be widely used in the aerospace model department. |
