A folding wing having a wing tip device () rotatable between flight and ground configurations, about an Euler axis of rotation (). The wing tip device () and a fixed wing () are separated along an oblique cut plane () passing through the upper and lower surfaces of the folding wing. A rotational joint () for coupling the wing tip device () to the fixed wing () during rotation between the ground and flight configurations. The rotational joint includes a follower () and a guide (), one which being fixed relative to the wing tip device and the other being fixed relative to the fixed wing. The follower and guide interlock such as by interlocking rings. The follower is received in the guide such that during rotation between the ground and flight configurations the follower moves along the arcuate path defined by the guide.

Rotational joint for an aircraft folding wing

A rotatable locking member for locking an aircraft wing with a movable wing tip device. The rotatable locking member including a U-shaped receiving portion arranged such that in an unlocked position the locking pin may be moved into and out of the U-shaped receiving portion, and in a locked position the locking pin is not able to be moved out of the U-shaped receiving portion, and the rotatable locking member is configured to be moved between the unlocked and locked position by rotational movement around the longitudinal central axis of the locking pin.

Folding wing tip and rotating locking member

An aircraft wing having a wing tip device at the tip thereof is disclosed. The wing tip device is configurable between: a flight configuration for use during flight and a ground configuration for use during ground-based operations to reduce span. In the flight configuration, flight loads may be transferred via a load transfer arrangement from the wing tip device into the fixed wing, but during movement of the wing tip device towards the ground configuration, the load transfer arrangement is disengaged. The wing includes an actuation assembly having a sliding chassis coupled to the wing tip device, via a track and follower arrangement. The track includes a wide portion and a narrow portion.

Actuation assembly with a track and follower for use in moving a wing tip device on an aircraft wing

An aircraft including a winghaving a fixed wingand a swing wing tip devicepivotably mounted about a pivotat the tip of the fixed wing, wherein the swing wing tip deviceis configurable between a flight configuration for use during flight and a ground configuration for use during ground-based operations, where the span of the aircraft wing is reduced. The swing wing tip deviceincludes a receiving portionarranged such that in the ground configuration, portions of the upper wing skin and lower wing skin of the fixed wing which are exposed in the flight configuration are at least partially received within the receiving portionof the swing wing

Swing wing tip

An aircraft wing is disclosed having a wing tip device configurable between a flight configuration for use during flight and a ground configuration for use during ground-based operations to reduce the span. The wing includes an actuator and an actuation assembly having an articulation mechanism having a master bell crank connected to the actuator and a slave link connecting the master bell crank with the wing tip device. The slave link is pivoted, at one end, to the master bell crank about a first pivot, and at the other end, to the wing tip device about a second pivot. The master bell crank being pivotably mounted, at its base, about a third pivot.

Articulation mechanism for forming a lock to hold a wing tip device in a ground configuration

An aircraft wing comprises a fixed wing and a wing tip device at the tip thereof. The wing tip device is configurable between: a flight configuration for use during flight and a ground configuration for use during ground-based operations to reduce the span. The wing comprises an actuation assembly for moving the wing tip device. The actuation assembly is arranged to move the wing tip device in a two-stage movement comprising a first stage in which the wing tip device is translated away from the flight configuration in a linear movement only, and a second, subsequent stage, in which the wing tip device is rotated to the ground configuration.
