A wing for an aircraft comprising:
- a fixed wing,
- a foldable wing tip portion mounted to the fixed wing via a first hinge rotatable about a first hinge axis between an extended position and a folded position, and
- an actuation unit configured to actuate the foldable wing tip portion to move about the first hinge axis,
- wherein the actuation unit is arranged at one of the fixed wing and the foldable wing tip portion, and is coupled to the other of the fixed wing and the foldable wing tip portion via a linkage including a first link element and a second link element,
- the first link element is mounted to a rotatable output of the actuation unit and is rotatably coupled to the second link element via a second hinge, and
- the second link element is rotatably coupled to the other of the fixed wing and the foldable wing tip portion via a third hinge.
An aircraft wing assembly including:
- a fixed wing,
- a wing tip portion coupled to the fixed wing by a first hinge which rotates about a first hinge axis as the wing tip portion moves between an extended position and a folded position, and
- an actuation unit mounted within the fixed wing and configured to move the foldable wing tip portion about the first hinge axis, wherein the actuation unit includes a rotatable output;
- a first link element attached to and turned by the rotatable output of the actuation unit;
- and
- a second link element having a first end section coupled to and moved by the first link element and a second end coupled to a location on the wing tip portion offset from the first hinge axis,
- wherein rotation of the rotatable output turns the first link element and moves to second link element to move the wing tip portion between the extended position and the folded position.
