摘　　要：针对高速飞行器大容积、高升力、低阻力和高升阻比的设计需求,提出高压捕获翼(High pressure zone Capture Wing,HCW)的概念.在高速巡航条件下,合理配置HCW可以充分利用来流压缩产生的高压气体,从而提高飞行器升力;HCW采用与来流平行的薄板装置,其附加阻力较小,可以大幅提高升阻比.采用CFD分析工具,比较不同容积的乘波体构型与HCW组合前后的气动性能.结果表明,在不同容积构型下升阻比均有明显提高,最小提升量可达10%.此外,容积越大,升力和升阻比增加效果越明显.As to the design requirements of large capacity, high lift, low drag and high lift-to-drag ratio for high speed aircrafts, the concept of High pressure zone Capture Wing（HCW） is proposed. Under the high speed cruise conditions, the rational configuration enables the HCW to make full use of the high pressure gas of inflow to improve the aircraft lift ; the HCW is a thin plate device paralleled to the inflow, the additional drag generated by the HCW is small and the lift-to-drag ratio can be improved greatly. As to the waverider configurations with different volume, a CFD analysis tool is used to compare the aerodynamic performance before and after the HCW is combined. The results show that the lift-to-drag ratio is significantly improved for different volume configurations and the minimum improvement rate reaches 10%. In addition, the volume is larger, the lift and the lift-to-drag ratio increase more.
