中文摘要	提出了高超声速飞行器参数化模型,并在此基础上通过快速、高效的工程方法开展了初步的气动力计算。以类HTV-2布局为对象,开展了以升阻比和容积率为设计目标的气动布局优化研究;以类X-37布局为对象,开展了以航程和驻点总加热量为设计目标的弹道优化设计。采用加权求和的方法求解多目标优化问题。研究表明,通过优化可获得设计目标权重取不同值时的优化结果,各优化结果具有明显的不同,具体将哪一个优化结果作为最终的选择,主要依赖于设计者的需求。; Uptodate,multi-objective optimization is widely adopted in the field of hypersonic vehicle configuration design.Generally speaking,aerodynamic characteristics are determined by the vehicle configuration,and the capability of completing the flight missions is determined by the design of flight trajectory. In this paper,the parametric geometrical configurations are proposed,and the aerodynamic characteristics are predicted by the rapid and effective engineering method. The configuration is optimized to satisfy the design goals of maximum lift-to-drag ratio and maximum volume utility ratio simultaneously. And the optimization of flight trajectory design considering the integration of aerodynamics and aerothermodynamics is investigated based on a given configuration example. The detailed research indicates that the optimal configuration and flight trajectory obtained by the optimization can fulfill the requests of the designers,and the results can be used as the feasible schemes in the future work. This research has a very obvious background of engineering application and value of application extension.
