Wing

A wing comprising a structure, an outer skin and a leading edge device, wherein said leading edge device comprises:

• a moveable body with a leading and a trailing edge and
• a support and actuation mechanism, comprising a plurality of arms with a first extremity, a second extremity, and a hinge near said first extremity for pivotally attaching the arm to said wing structure, and attached to said moveable body near said second extremity, wherein the hinges of said plurality of arms are substantially aligned along a hinge line, for attaching said moveable body to said wing structure and driving a substantially circular motion of said moveable body, around said hinge line, between a retracted position and at least one deployed position,
• said wing being characterised in that:
• said leading edge device further comprises at least one guiding device, separate from said support and actuation mechanism, and comprising a track and a follower, such as a roller, for cooperating with said track, wherein one of the track and the follower is fixed to said wing structure, whereas the other one of the track and the follower is fixed to said moveable body, and the follower is arranged to be guided by the track along a substantially circular arc substantially centred on said hinge line and hold down said moveable body so as to substantially restrict lift-off of its trailing edge from said outer skin of the wing in at least on positions.
