The present invention is directed to a unique foldable winglet assembly adaptable for use with an aircraft for maximizing the wing span of the aircraft during cruise operation while reducing wing bending moment during extreme flight maneuvers. A foldable winglet is pivotally joined to the aircraft wing and is rotatable during flight between a retracted position and a fully extended position. An actuator is mounted on the aircraft wing and attached to the foldable winglet. When the aircraft reaches cruise operation, the actuator can be manually or automat...
[ Having thus described my invention, what I claim as new and desire to secure by Letters Patent is as follows:] [1.] An improved aircraft including at least one wing, comprising:a foldable winglet located at an outboard end of each wing;a separate hinge assembly joining each wing to a respective one of the foldable winglets, allowing the respective winglet to pivot relative to the wing between a retracted position wherein the winglet extends substantially perpendicularly to an inboard portion of the wing and a fully extended position wherein the respect...
