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

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.
