高压捕获翼双翼构型宽速域气动性能研究

Research on Aerodynamic Performance of High-Pressure Capturing Wing with Bi-Wing Configuration in Wide-Speed Range

宽域高超飞行器气动布局设计已是研究热点之一。高压捕获翼新型气动布局可同时满足高容积率、高升力和高升阻比,此布局前期研究主要针对高超声速状态。基于该背景,以宽域高超飞行器为主要目标,依据高压捕获翼基本设计原理,发展了一种新型双翼构型。对该构型的宽速域气动特性研究结果表明,在亚声速条件下添加捕获翼可使飞行器升力系数提高约16.6%,在跨声速区域捕获翼可抑制飞行器气动焦点跳变,飞行器在全速域范围内均为纵向静稳定。

The aerodynamic configuration design of wide-range hypersonic vehicle has become one of the research hotspots.The new aerodynamic configuration of high-pressure capturing wing(HCW)can meet the requirements of high volume ra-tio,high lift and high lift-to-drag ratio at the same time.The preliminary research of this configuration is mainly aimed at the hypersonic state.Based on this background,this paper took the wide-range hypersonic vehicle as the main target and developed a new bi-wing configuration according to the basic design principle of HCW.The research results show that the lift coefficient of the vehicle can be increased by about 16.6%when the capturing wing is added in the subsonic range.Furthermore,the capturing wing can suppress the jump of the aerodynamic focus of the vehicle in the transonic range,and the vehicle is statically stable in the wide-speed range.
