英文摘要The High-pressure Capturing Wing aerodynamic configuration (abbreviated as HCW) can enhance the aircraft's lift and lift-to-drag ratio through the effective utilization of favourable aerodynamic interference between the fuselage and the capturing wing (abbreviated as CW). Consequently, the fuselage shape significantly influences not only the aerodynamic characteristics of the fuselage but also those of the CW. In this study, based on the concept of a fuselage of revolution combined with CW, the effects of different fuselage profile shapes-specifically, conical profile, 3/4-power profile, and Karman profile-on the aerodynamic characteristics of the HCW configuration are systematically investigated using a numerical simulation technique. The results indicate that while the 3/4-power and Karman configurations differ from the conical configuration by employing non-uniform compression, which increases the fuselage volumes by 18.5 % and 48.1 %, respectively, they achieve drag reductions of 6.7 % and 1.1 % under the design condition at Ma = 6. Moreover, due to the influence of different fuselage profiles on the flow characteristics, the peak pressure on the lower surface of the CW is reduced for both the 3/4-power and Karman configurations, while the area of the high-pressure zones is increased. Overall, compared to the conical configuration, the 3/4-power configuration exhibits a slight decrease in lift, whereas the Karman configuration demonstrates a significant increase in lift. Both configurations achieve an increase in the lift-to-drag ratio. Additionally, an analysis of the effects of different Mach numbers (Ma = 7, Ma = 8) that as the Mach number increases, the lift becomes more sensitive for both the 3/4-power and Karman configurations. However, compared to the conical configuration, both configurations keep exhibiting a decrease in overall drag and an increase in the lift-to-drag ratio. Furthermore, under different Mach number conditions, the centers of pressure for both configurations shift rearward.
