Patent abstract
Embodiments of the present invention relate to a winglet for an end or tip of an aircraft wing. The winglet includes an inner portion that curves upward having a large radius of curvature near the wing, a middle portion having a small radius of curvature forming a bend, and an outer portion having a large radius of curvature extending to a tip of the winglet. The winglet lowers induced drag of the wing and improves aircraft performance especially for wing tip extensions that extend upwards about equal to or slightly more than outwards.
