An actuating system for pivoting a wing tip section () about a fixed wing base section (), and including a heating arrangement () positioned and adapted to be operable to heat at least one portion of an actuating arrangement () that pivots the wing tip section such that at least for ambient temperatures below a predetermined temperature the required work to be effected by the actuator () when moving the second coupling part () between the first position and the second position is lower than without heating the at least one portion.

Actuating system for actuating a foldable wing tip portion of a wing for an aircraft

A method for testing an arresting unit () for locking a foldable wing tip portion () to a wing () that includes a fixed wing (), a foldable wing tip portion (), and a folded position, an actuation unit () for actuating movement of the foldable wing tip portion (), and an arresting unit () for locking the foldable wing tip portion (). The method includes: locking the foldable wing tip portion () in the extended position by the arresting unit (), controlling the actuation unit () to move the foldable wing tip portion () in the direction towards the folded position, such that the foldable wing tip portion () urges against the arresting unit () with a predefined test load, detecting deformation of the arresting unit () during or after application of the test load, and comparing the detected deformation to a predefined threshold deformation.

Method for testing operation of an arresting unit for locking a foldable wing tip portion in an extended position

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 () 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.

Wing arrangement for an aircraft

A method to control folding of a wing tip section about a fixed base wing section by a control system that automatically determines whether: (i) a command signal is received to fold the wing tip section, (ii) a first condition indicating signal indicates that the aircraft is on the ground; (iii) the current speed of the aircraft is no greater than a preset maximum speed, and (iv) the aircraft is not at gate in an airport.

Method and a control unit for controlling actuation of a foldable wing tip section of a wing of an aircraft

A method for operating a wing () including a fixed wing (), a foldable wing tip portion () mounted to the fixed wing () pivotally between an extended position and a folded position, an actuation unit () for actuating movement of the foldable wing tip portion (), and an arresting unit () for locking the foldable wing tip portion () in the extended position and/or in the folded position. The method includes controlling the actuation unit () to move the foldable wing tip portion () either to the extended position or to the folded position until the foldable wing tip portion () or the actuation unit () contacts a stop element (), continuing actuation until the actuation unit () reaches a stall condition, detecting the stall condition of the actuation unit (), and locking the arresting unit () upon detection of the stall condition.

Method for operating a wing for an aircraft including a foldable wing tip portion

A method to detect a failure of a sensor or system in an aircraft, wherein the aircraft includes a wing including a fixed wing and a wing tip device pivotably mounted to the fixed wing, a sensor system, and a control unit including a system behavior model which models a target vale of an operation parameter of the wing, wherein the method includes: detecting a value of an operation parameter by the sensor system; comparing the detected value of the operation parameter to a corresponding target value of the operation parameter obtained from the system behavior model, and declaring a sensor failure or a system failure in response to determining a predefined deviation of the detected value from the corresponding target value of the operation parameter, detecting a sensor failure or a system failure.
