Low Speed Aerodynamic Characteristics of Wings of Aspect Ratios 3 and 4 Equipped with High Lift Systems

Abstract

Low speed wind tunnel data show that wings of aspect ratios 3 and 4 can produce maximum lift coefficients twice that of conventional double-slotted flap configurations by using powered high lift systems. These high lift systems, which utilize either the circulation control or upper surface blowing concepts, were applied to a semispan wing-fuselage model having a supercritical airfoil section.
