Abstract: A latching unit in an aircraft wing having a fixed wing part and a hinged wing tip foldable about a hinge axis, including a first latching actuator driven by a drive unit within the fixed wing part and coupled to a first latching bolt and a second latching actuator coupled to a second latching bolt with both latching bolts configured for locking or unlocking hinge levers extending into the latching unit. The latching actuators include hollow screw shafts having threaded rods extending in opposite directions from adjacent ends of the hollow screw shafts and engaging with threaded elements provided in end portions of the respective latching bolts, and wherein the latching bolts are movable in opposite axial directions into a locking or unlocking position by rotation of the threaded rods. An aircraft wing and aircraft having such wing are disclosed.

Abstract: An actuation and latching system in an aircraft wing having a fixed wing part and a foldable wing tip part, including at least one tip actuation unit providing an interface between the fixed wing part and the foldable wing tip having hinge levers, a latching unit in the fixed wing part and including latching bolts displaceable in opposite directions parallel to the hinge axis and that can engage with the hinge levers extending into the latching unit, a drive unit in the fixed wing part and axially down-stream of the latching unit and having at least a first drive shaft coupled to the latching unit and a second drive shaft passing through the latching unit and coupled to the tip actuation unit, and a controller for the drive unit. A method for extending the foldable wing tip part of an aircraft wing, an aircraft wing and an aircraft are disclosed.

Abstract: An actuation assembly (10) including a control unit (40), a monitoring unit (50), at least one high voltage power supply (32), a low voltage power supply (34) and power bridges (60a, 60b). The low voltage power supply (34) is connected to a source to provide power to the control unit (40) and to the monitoring unit (50), wherein the control unit (40) and the monitoring unit (50) monitor elements of a sub-system including an electric motor, a brake or a sensor. The high voltage power supply (32) is connected to a source to provide power to each of the power bridges (60a, 60b). The power bridges (60a, 60b) are coupled with an electric motor.

Abstract: A binding machine for binding sheets in a stack by the application of glue along one edge of the sheets. The binding machine incorporates a manually operated clamp mechanism to hold the sheets together with sufficient compression to maintain the proper alignment of the sheets for the application of glue to the sheet edge.
