摘要： 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).

摘要： A wing for an aircraft is disclosed including a main wing and a trailing edge high lift assembly having a flap, and a connection assembly movably connecting the flap to the main wing, such that the flap is movable between a retracted position and at least one extended position, wherein the connection assembly includes a support element that is mounted to the flap and that is movably mounted to the main wing, such that the support element is movable relative to the main wing along a predefined path between a stowed position and a deployed position. The support element is formed as an elongate support beam that extends along a beam longitudinal axis between a front end and a rear end and has an intermediate portion between the front and rear ends.

摘要： To improve reliability and safety of an actuator assembly for a high-lift device, a torque sensing device is provided on a static structural part, which is used to mount the actuator of the actuator assembly to an aircraft interface, such as a rib or an interconnection strut. A controller determines a reaction torque value based on the output signal of the torque sensing device and monitors and controls the actuator based on the reaction torque value and predetermined load thresholds.

摘要： A drive system for driving a movable flow body is disclosed having a drive unit, a shaft, a torque sensing device, a no-back friction unit, and an axial bearing. The drive unit is coupled with the shaft to rotate the shaft, the torque sensing device is coupled with at least one of the drive unit and the shaft to detect a torque transferred from the drive unit into the shaft, the no-back friction unit is arranged between the axial bearing and an axial support means of the shaft, such that an axial load of the shaft is supported by the axial bearing, and the no-back friction unit is configured to substantially not counteract a rotation of the shaft in a first direction of rotation of the shaft and to apply a friction-induced additional torque to the shaft in an opposite second direction of rotation.

摘要： 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).

摘要： 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).

摘要： An aircraft wing including a flap system mounted at a leading or trailing edge of the wing and includes at least two movable flap devices spaced apart in a spanwise direction Y from each other, each movable flap device supported by at least one support station and driven about a hinge axis by at least one drive system. The flap system includes a synchronizing torque element connected to the movable flap devices, wherein the synchronizing torque element is configured to transmit a torque between the movable flap devices to actuate a rotational movement of the movable flap devices, and wherein the synchronizing torque element is positioned between the movable flap devices and around an adjacent system or structural component that is also positioned between the movable flap devices.

摘要： 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.
