초록

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...

청구항

[ 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...
