A vortex dissipator for the tip of an airfoil or hydrofoil lifting surface is formed as a fixed plate secured to the tip and aligned with the free stream direction. The plate extends forward from the trailing edge of the tip and outward from the suction side of the lifting surface and is configured so that the resultant of the velocity of the free stream flow and the rotational velocity of the vortex produces a stall angle of attack relative to the plate and dissipates much of the strength of the vortex. |
