Abstract
Embodiments of the present disclosure include a curved planar wingtip for a straight wing and a curved planar wingtip for a swept wing of an aircraft. The curved planar wingtips include a member that extends from the end of the wing in a direction aft of the wing trailing edge while remaining substantially planar with the wing. The curved planar wingtips curve continuously from leading and trailing edges of the wing to form a tip located aft of the wing. Other embodiments of the curved planar wingtip are configured for a horizontal or vertical tail. Yet another embodiment includes a curved wingtip that extends aft of a trailing edge of the wing by a distance greater than the curved wingtip extends above a top surface of the wing.
