A wing, comprising a structure, an outer skin, and a leading edge device comprising a moveable body with a leading and a trailing edge and a support and actuation mechanism for attaching said moveable body to a structure of a wing and guiding a substantially circular motion of said moveable body, around a hinge line, between a retracted position and at least one deployed position. Said leading edge device further comprises at least one guiding device comprising a track and a follower with a roller. The track follows a substantially circular arc substantially centered on the hinge line. The roller is arranged to be guided by the track and hold down said moveable aerodynamic surface so as to substantially restrict lift-off of its trailing edge from the outer skin of the wing.

1. A wing comprising a wing structure, an outer skin and a leading edge device, said leading edge device comprising: a moveable body having a leading and a trailing edge;an actuation mechanism comprising a plurality of driven arms for attaching said moveable body to said wing structure, each driven arm having a first extremity, a second extremity, and a hinge located near said first extremity for pivotally attaching each driven arm to said wing structure, each driven arm being attached to said moveable body near said second extremity, said hinges of said plurality of driven arms being substantially aligned with one another and together defining a hinge line, said and actuation mechanism driving said moveable body in a substantially circular motion around said hinge line between a retracted position and at least one deployed position; anda support and guiding mechanism comprising a plurality of support arms for attaching said moveable body to said wing structure, each support arm having a hinge for pivotally attaching each support arm to said wing structure, said hinges of said support arms being substantially aligned along said hinge line, and at least one guiding device associated with at least one support arm and which comprises a track and a follower for cooperating with said track, wherein said track and said follower are fixed between said wing structure and said moveable body, said follower being arranged to be guided by said track along a substantially circular arc substantially centered on said hinge line and to hold down said moveable body so as to substantially restrict lift-off of said trailing edge from said outer skin of said wing in said at least one deployed position. 2. A wing according to claim 1, wherein said other one of said track and said follower of said guiding device is fixed to said moveable body closer to said trailing edge than to said leading edge. 3. A wing according to claim 1, wherein at least one support arm is integrally formed with at least part of said moveable body. 4. A wing according to claim 1, wherein at least one support arm is linked to said moveable body with a single point attachment. 5. A wing according to claim 1, wherein at least one support arm is linked to said moveable body with an attachment comprising two eccentrically adjustable pins. 6. A wing according to claim 1, wherein at least one support arm is linked to said moveable body with a three-point attachment, said three-point attachment comprising a linkage providing a first attachment point between said support arm and said linkage and a second attachment point between said linkage and said moveable body, and a third attachment point between said support arm and said moveable body. 7. A wing according to claim 1, wherein said follower of said guiding device is fixed to said moveable body and said track of said guiding device is fixed to said wing structure. 8. A wing according to claim 7, wherein said track of said guiding device is fixed to said wing structure under said outer skin and said follower of the guiding device traverses said outer skin through a cut-out in said outer skin. 9. A wing according to claim 1, wherein said follower comprises a roller having a rotation axis, said roller being mounted on an eccentric bushing, said eccentric bushing providing adjustment for the position of said rotation axis to compensate for play in said guiding device. 10. A wing according to claim 1, wherein said follower comprises a roller having a rotation axis which is pivotable around at least one axis perpendicular to said rotation axis to compensate for angular misalignments in said guiding device. 11. A wing comprising a wing structure, an outer skin and a leading edge device, said leading edge device comprising: a moveable body having a leading and a trailing edge,an actuation mechanism comprising a plurality of first tracks in substantially parallel planes, each first track comprising a substantially circular arc centered on a point along a virtual hinge line, said first tracks being substantially rigidly attached to said moveable body to support and guide said moveable body while in a motion between a retracted position and at least one deployed position with respect to said wing structure, andat least one guiding device located substantially offset between said planes of said first tracks, said at least one guiding device comprising a second track and a follower for cooperating with said second track, wherein said second track and said follower are fixed between said wing structure and said moveable body, said follower being arranged to be guided by said second track in a plane substantially parallel to the planes of the first tracks, said moveable body following a substantially circular motion around said virtual hinge line while in motion between said retracted position and said at least one deployed position. 12. A wing according to claim 11 wherein said follower of said guiding device is fixed to said moveable body and said second track of said guiding device is fixed to said wing structure. 13. A wing according to claim 11, wherein said follower of said guiding device is fixed to said wing structure and said second track of said guiding device is fixed to said movable body. 14. A wing according to claim 2, wherein at least part of said moveable body includes a rib and at least one support arm is integrally formed with said rib. 15. A wing according to claim 4, wherein said single point attachment comprises a spherical bearing. 16. A wing according to claim 1, wherein said follower comprises a roller. 17. A wing according to claim 8, wherein said cut-out in said outer skin is sealed with a spring loaded door seal. 18. A wing according to claim 8, wherein said cut-out in said outer skin is sealed with a sliding curtain seal. 19. A wing according to claim 11, wherein said follower comprises a roller.
