Abstract: A mechanism for extending and supporting a high-lift device relative to an airfoil has a pair of support ribs coupled to the airfoil. A carrier track is pivotally coupled to the high-lift device and positioned between the pair of support ribs. The carrier track has a slot opening along a lower length thereof. A gear rack is coupled within the slot opening. A pinion gear is positioned between the support ribs and below the carrier track. The pinion gear engages with the gear rack for extending the high-lift device relative to the airfoil. A plurality of rollers is rotateably coupled to the support ribs and in bearing contact with the carrier track. At least one roller is positioned above the carrier track and a second roller is positioned below the carrier track. The second roller is positioned concentrically with the pinion gear.

Abstract: An apparatus for an airplane or other equipment is provided. The apparatus may comprise a multitude of connected arms which are adapted to rotate relative to one another. One end of the apparatus may be connected to a fixed wing, while another end of the apparatus may be connected to a moving slat. The apparatus may be used to deliver conduit from the fixed wing to the moving slat. The conduit may comprise one or more of an electrical de-icing wire, a sensor wire, a control wire, a fiber optic line, and a pneumatic line. Within an internal pathway of the apparatus, the conduit may be freely looped around a curved surface at least one-half turn and fixedly secured to a linear surface. Methods of use and assembly are also provided.

Abstract: The present invention is directed generally toward leading edge flap apparatuses and corresponding methods. One aspect of the invention is directed toward an aircraft system having an airfoil, an actuator driver, and a leading edge device with two flow surfaces and six links. In a further aspect of the invention, the flow surfaces of the leading edge device are at least approximately located in the same position when the actuator driver is in two different positions. Another aspect of the invention is directed toward an aircraft system having an airfoil and a leading edge device movable between at least a retracted position and an extended position along a motion path having two segments. The second flow surface can be positioned generally behind and/or generally above the first flow surface when the first and second flow surfaces are located in the first segment of the motion path.

Abstract: Aircraft and leading edge apparatuses and corresponding methods are disclosed. In one embodiment, an aircraft system includes an airfoil with a leading edge device that is movable among a retracted position, at least one first extended position, and a second extended position. A first actuator can be operatively coupled to the leading edge device to move the flow surface between the retracted and the at least one first extended position. A second actuator can be operatively coupled to the leading edge device to move the flow surface between the at least one first extended position and the second extended position.
