Wing for an aircraft

An aircraft wing assembly including:

• a fixed wing,
• a wing tip portion coupled to the fixed wing at a first hinge which rotates about a first hinge axis as the wing tip portion moves between an extended position and a folded position, wherein the first hinge axis extends through an end of the wing tip portion and an end of the fixed wing, 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 having a first end portion attached to the rotatable output of the actuation unit, wherein the rotatable output turns the first end portion and rotates the first link element about an output axis perpendicular to the first link element;
• 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 positon, and
• wherein the first link element and the second link element are within the fixed wing while the wing tip portion is in the extended position, and extend out from the fixed wing while the wing tip portion is in the folded position.
