Three-dimensionality of leading-edge vortices on high aspect ratio plunging wings

Abstract
Experiments that explore leading-edge vortex formation for plunging high-aspect-ratio swept and unswept wings are presented. For the unswept wing, the leading-edge vortex sheds and moves inboard, whereas on the swept wing, it moves outboard, leading to significant differences in the wing root bending moment. Axial velocity distribution through the vortex filament revealed jetlike, wakelike, and uniform axial velocity profiles.
