Title: Experimental Studies on 50.DEG. Delta Wings with Rounded Leading-Edge Vortex Flaps.
Abstract: Low speed wind tunnel measurements were done on a 50° delta wing with rounded leading-edge vortex flaps in order to assess the benefits of the rounded leading-edge vortex flaps. Deflecting the rounded leading-edge vortex flap improves the lift/drag ratio at relatively higher lift coefficients, when compared with the sharp edged vortex flap.
