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 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.
