A wing () having a base section () and a tip section () pivotably connected to the base section () such that the tip section () is pivotable between a deployed position and a stowed position in which the spanwise length of the wing () is smaller than in the deployed position. The wing arrangement also has an actuating arrangement () including a linear hydraulic actuator () coupled between the base section () and the tip section () such that it is operable to selectively move the tip section () between the deployed position and the stowed position, a first and a second hydraulic connection portion () connected to the linear hydraulic actuator () such that they are in fluid communication with different chamber sections () of a cylinder () of the linear hydraulic actuator (), and a first hydraulic subsystem () and a second hydraulic subsystem ().

Foldable wing and actuator arrangement

A latching device for a wing including a support structure (), a latching bolt () having a longitudinal axis () and being slidably supported by the support structure () such that the latching bolt () is movable between a retracted position and an extended position. The latching device () includes a first hydraulic actuator () and a first connector assembly () adapted to be connected to a first hydraulic system of an aircraft (), and at least one second hydraulic actuator () and a second connector assembly () connected to a second hydraulic system. The first hydraulic actuator () and the second hydraulic actuator () are adapted to effect movement of the latching bolt () from the extended position into the retracted position independent of the other one of the at least one first hydraulic actuator () and the at least one second hydraulic actuator ().

Latching device for a foldable wing arrangement

A wing () having a fixed wing () and a wing tip device () rotatable between a flight configuration and a ground configuration, a rotational joint () rotatably couples the wing tip device () to the fixed wing () and a locking mechanism () locks the wing tip device () in the flight and ground configurations. The locking mechanism () includes first and second locking members () and first and second receiving members (), the locking mechanism () being configured to lock the wing tip device () in one of the flight configuration and ground configuration by receiving the first and second locking members () in the first and second receiving members () respectively, and to lock the wing tip device () in the other of the flight configuration and ground configuration by receiving the first locking member () in the second receiving member ().

Rotational joint for an aircraft folding wing

A wing () having a base section () and a tip section (), the base section () having a first end portion () and a second end portion (), the tip section () having a third end portion () and a fourth end portion (), wherein the second end portion () and the third end portion () are coupled so that the tip section () is pivotable with respect to the base section () about a pivot axis ('), and an actuating arrangement having an actuator () which is coupled to the base section () and the tip section () and which is operable to effect a pivotal movement of the tip section () relative to the base section () between a stowed position and a deployed position.

Foldable wing and actuating arrangement

A system for locking a foldable wing tip on a wing end of an aircraft includes at least one engagement device, at least one locking device comprising a support, a latch element rotatably held in the support and a lock element movably held on the support, a latch drive device coupled with the latch element of the at least one locking device for selectively rotating the latch element at least to an open position, a closed position and a test position, a lock drive device coupled with the lock element of the at least one locking device for selectively varying a distance of the lock element to the latch element between a neutral position and a locking position, wherein the support includes a receiving space extending into an insertion opening designed for receiving the engagement device. The latch element includes a circumferential surface section that selectively covers the insertion opening in an open position and uncovers the insertion opening in a closed position of the latch element. The latch element includes at least one locking recess arranged on a circumferential path of motion for engaging with the lock element in the closed position of the latch element and the locking position of the lock element. The rotatable latch element further includes at least one protrusion on the circumferential path of motion, which acts as a stop for the lock element. The system further includes a signaling device indicating a correct function when the lock element rests on the at least one protrusion.
