A numerical comparison between a high aspect ratio curved wing and a traditional swept wing, both designed with similar supercritical aerodynamic profiles (10-Percent-Thick Supercritical Airfoil SC(2)-0410 - NASA Supercritical Airfoil), shows an important reduction (over 5%) of drag coefficient under high subsonic flight conditions (Mach Number = 0.85).
