Abstract: A wing (3) for an aircraft (1) including a fixed wing (5), a foldable wing tip portion (9) mounted to the fixed wing (5) via a first hinge (11) rotatable about a first hinge axis (13) between an extended position (15) and a folded position (17), and an actuation unit (19) arranged at the fixed wing (5) and coupled to the foldable wing tip portion (9) via a linkage (21) including a first link element (23) and a second link element (25), wherein the first link element (23) is mounted to a rotatable output (27) of the actuation unit (19) and is rotatably coupled to the second link element (25) via a second hinge (29), and wherein the second link element (25) is rotatably coupled to the foldable wing tip portion (9) via a third hinge (31).

Abstract: A latching device for a wing (3) including a base (11) and a tip section (13). There is a first bore (27) extending from the base section (11) and a second bore (27) extending from the tip section (13) wherein the bores are aligned when the tip section is deployed for flight and out of alignment when the tip section (13) is folded. The latching device (29) includes a housing (33) with an interior cavity (35), a spindle (39) in the interior cavity, a nut (47) threaded on the spindle, wherein rotation of the spindle causes; a latching bolt (31) coupled to the nut (47) and being moved as the nut moves along the rotating spindle between retracted and extended positions; a guide (49) to guide the nut (47) along the spindle and of the latching bolt between the retracted position and the extended position, and a latch actuator (41).

Abstract: A wing arrangement for an aircraft is disclosed including a wing having a base section with a first end portion, which is adapted to be secured to the fuselage of an aircraft, and an opposite second end portion, and a tip section with a third end portion and an opposite fourth end portion. The third end portion is pivotably connected to the second end portion such that the tip section (9) is selectively pivotable about a tip section pivot axis between a deployed position and a folded position in which the spanwise length of the wing is smaller than in the deployed position. An actuating system including an actuator and coupled between the base section and the tip section such that the actuator is operable to selectively move the tip section between the deployed position and the folded position. The actuating system includes at least one first component arranged and adapted to move upon operating the actuator.

Abstract: A wing for an aircraft is disclosed having a fixed wing, a foldable wing tip portion mounted to the fixed wing via a first hinge rotatable about a first hinge axis between an extended position and a folded position, and an actuation unit for actuating the foldable wing tip portion for movement about the first hinge axis. A wing having an actuation unit with reduced complexity and weight and that is arranged entirely inside the outer contour of the wing is disclosed in which the actuation unit is arranged at one of the fixed wing and the foldable wing tip portion and is coupled to the other of the fixed wing and the foldable wing tip portion via a linkage. The linkage includes a first link element and a second link element, wherein the first link element is rotatably mounted to the one of the fixed wing and the foldable wing tip portion via a second hinge and is rotatably coupled to the second link element via a third hinge.

Abstract: A wing for an aircraft is disclosed having a fixed wing, and a foldable wing tip portion mounted to the fixed wing via a tip hinge rotatable about a tip hinge axis between an extended position and a folded position. An arresting device is provided that allows to arrest the foldable wing tip portion with respect to the fixed wing in a very precise position and at the same time can be engaged in a simple and quick manner, is achieved in that the wing includes an arresting system including a first hook mounted to the foldable wing tip portion and a second hook mounted to the fixed wing, wherein the first hook and the second hook are configured to be moved relative to one another between an arrested position, where the first and second hooks are engaged and relative movement of the first and second aircraft components is inhibited, and a release position, where the first and second hooks are disengaged and relative movement of the first and second aircraft components is allowed.

Abstract: A wing arrangement for an aircraft is disclosed including a wing having a fixed wing portion and a wing tip portion, wherein a the wing tip portion is pivotably connected to the fixed wing portion such that the wing tip portion is selectively pivotable about a pivot axis relative to the fixed wing portion between a first wing tip portion position and a wing tip portion second position, an actuator having an output element adapted to transfer an actuating torque and/or force to the wing tip portion for actuating the wing tip portion for movement about the pivot axis. The output element is movable between a first actuator position and a second actuator position, a first end stop for preventing movement of the wing tip portion beyond the first wing tip portion position, a detector adapted to detect a position of the output element, and a control unit adapted to control the actuating torque and/or force of the actuator based on the detected position of the output element.

Abstract: A consumable supply item for an imaging device holds an initial or refillable volume of ink. A housing defines an interior having a pair of opposed electrodes. The electrodes have a capacitance that varies in response to an amount of liquid between them. A controller energizes one electrode and receives an output reading from the other. The controller processes the reading on board the housing and supplies it as a digital data stream to the imaging device during use. A memory stores calibration values for an empty and full housing. The controller writes back to the memory present fluid levels obtained from the output reading of the electrode. An enable output allows operation or not of a fluid pump in the imaging device. Materials, construction, modularity, and fluid communication ports are further embodiments, to name a few.
