摘　　要：气动技术是高超声速飞行器的重要支撑技术,气动布局的选择与确定是影响飞行器总体方案论证的重要因素。以一类面对称滑翔飞行器为研究对象,采用针对高超声速飞行器的快速工程算法,建立参数化外形的气动数据库,实现由气动布局要素到总体性能指标的映射,并通过数据分析方法,如相关性分析、灵敏度分析等,梳理出影响高超声速滑翔飞行器不同总体性能的关键气动外形几何参数,并进行相关性排序,研究结果可指导高超声速滑翔飞行器的布局设计及优化。Aerodynamic technique is vital to the design of hypersonic vehicle. Aerodynamic configuration is the key factor the overall design of the vehicle. A series of plane-symmetric hypersonic gliding vehicles were investigated in this paper. An aerodynamic database with parametric configuration was established through a high efficient engineering algorithm for hypersonic vehicle. A mapping from parametric configuration to general performance index was achieved. With the use of database analysis method such as correlation analysis and sensitivity analysis,several key geometry parameters of aerodynamic configuration were discovered,which influence the relevant general performance of hypersonic gliding vehicle. The relevance ranking was studied,which can be used to guide the configuration design and optimization of hypersonic gliding vehicle.
