Abstract: A wing (9) having a base section (11) and a tip section (13) pivotably connected to the base section (11) such that the tip section (13) is pivotable between a deployed position and a stowed position in which the spanwise length of the wing (9) is smaller than in the deployed position. The wing arrangement also has an actuating arrangement (19) including a linear hydraulic actuator (21) coupled between the base section (11) and the tip section (13) such that it is operable to selectively move the tip section (13) between the deployed position and the stowed position, a first and a second hydraulic connection portion (79a, 79b) connected to the linear hydraulic actuator (21) such that they are in fluid communication with different chamber sections (27a, 27b) of a cylinder (25) of the linear hydraulic actuator (21), and a first hydraulic subsystem (81a) and a second hydraulic subsystem (81b).

Abstract: A wing (1) having a fixed wing (3) and a wing tip device (4) rotatable between a flight configuration and a ground configuration, a rotational joint (10) rotatably couples the wing tip device (4) to the fixed wing (3) and a locking mechanism (46) locks the wing tip device (4) in the flight and ground configurations. The locking mechanism (11) includes first and second locking members (51, 52) and first and second receiving members (53, 54), the locking mechanism (11) being configured to lock the wing tip device (4) in one of the flight configuration and ground configuration by receiving the first and second locking members (51, 52) in the first and second receiving members (53, 54) respectively, and to lock the wing tip device (4) in the other of the flight configuration and ground configuration by receiving the first locking member (51) in the second receiving member (54).

Abstract: A latching device for a wing including a support structure (29), a latching bolt (35) having a longitudinal axis (36) and being slidably supported by the support structure (29) such that the latching bolt (35) is movable between a retracted position and an extended position. The latching device (27) includes a first hydraulic actuator (47a) and a first connector assembly (38a) adapted to be connected to a first hydraulic system of an aircraft (1), and at least one second hydraulic actuator (47b) and a second connector assembly (38b) connected to a second hydraulic system. The first hydraulic actuator (47a) and the second hydraulic actuator (47b) are adapted to effect movement of the latching bolt (35) from the extended position into the retracted position independent of the other one of the at least one first hydraulic actuator (47a) and the at least one second hydraulic actuator (47b).

Abstract: A wing (5) having a base section (5) and a tip section (13), the base section (7) having a first end portion (9) and a second end portion (11), the tip section (13) having a third end portion (15) and a fourth end portion (17), wherein the second end portion (11) and the third end portion (15) are coupled so that the tip section (13) is pivotable with respect to the base section (7) about a pivot axis (19, 19?), and an actuating arrangement having an actuator (21) which is coupled to the base section (7) and the tip section (13) and which is operable to effect a pivotal movement of the tip section (13) relative to the base section (7) between a stowed position and a deployed position.

Abstract: 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.
