宽速域高压捕获翼气动构型及其跨声速气动特性
A novel wide-speed-range configuration based on high-pressure capturing wing concept and its transonic aerodynamic characteristics
摘要
Abstract
In recent decades,wide-speed-range aircraft with hypersonic cruise capability have garnered significant at-tention and emerged as a prominent research focus worldwide.However,a wider flight velocity range poses signifi-cant challenges to aerodynamic configuration design.To effectively overcome the trade-off between lift-to-drag ratio and volumetric efficiency,we propose a novel aerodynamic configuration with high volumetric capacity based on the high-pressure capturing wing concept.Numerical simulations demonstrate that this configuration achieves a maximum lift-to-drag ratio of 5.89 at Mach number 6.0,representing an improvement of over 18%compared to a reference con-figuration without the high-pressure capturing wing.Furthermore,numerical simulations and analyses were conducted focusing on two typical transonic conditions at Mach number 0.8 and 1.2.The results demonstrate that compared to the reference configuration,the new high-pressure capturing wing configuration exhibits increased lift and drag coeffi-cients to varying degrees under both transonic conditions.Although this comes with some degradation in lift-to-drag ra-tio,the shift of the aerodynamic center is significantly reduced across the wide speed range.Specifically,the relative shift of the aerodynamic center is reduced by 11.1%in the transonic regime and by 49.9%across the transonic-to-hypersonic regime.Further analysis reveals that this reduction in aerodynamic center shift is primarily attributed to the coupling effects between the additional wing surface and the fuselage.关键词
