An aircraft is provided with a wing assembly mounted in a slipstream of a source of propulsion of the aircraft. The aircraft includes a body having a longitudinal axis, a wing assembly carried by the body and including a moveable portion moveable relative to the body and a wing carried by the moveable portion. A first actuator is coupled to the moveable portion to move it relative to the body in a direction generally parallel to the axis of the body. A second actuator is coupled to the wing to move the wing relative to the moveable portion and between first and second positions. The second actuator at least selectively permits uninhibited pivoted movement of the wing relative to the body in response to aerodynamic forces acting on the wing so that the wing may pivot to a position wherein the forces acting on the wing are balanced.

We claim: 1. An aircraft having a wing assembly mounted in a slipstream of a source of propulsion of the aircraft, comprising: a body having a longitudinal axis; a wing assembly carried by the body and including a moveable portion moveable relative to the body and a wing carried by said moveable portion; a first actuator coupled to said moveable portion to move said moveable portion relative to the body in a direction generally parallel to said longitudinal axis; and a second actuator coupled to the wing to move the wing relative to said moveable portion and between first and second positions, and wherein said second actuator at least selectively permits uninhibited pivoted movement of the wing relative to the body in response to aerodynamic forces acting on the wing so that the wing may pivot to a position wherein the forces acting on the wing are balanced. 2. The wing assembly of claim 1 further comprising a third actuator operable to at least selectively control the pivoted movement of the wing. 3. The wing assembly of claim 2 wherein said first, second and third actuators are operable independently from one another. 4. The wing assembly of claim 1 wherein the first actuator drives the moveable portion fore and aft relative to the body. 5. The wing assembly of claim 1 wherein the first actuator pivots the moveable portion relative to the body. 6. The wing assembly of claim 1 wherein the second actuator drives the wing fore and aft between first and second positions relative to the body. 7. The wing assembly of claim 6 wherein the second actuator is operable to move the wing in any pivoted orientation of the wing relative to the second actuator. 8. The wing assembly of claim 6 wherein the second actuator permits pivoted movement of the wing relative to the second actuator so that the wing can pivot to a position wherein the forces acting on the wing are balanced in any position of the wing between or in its first and second positions. 9. The wing assembly of claim 1 wherein the moveable portion includes a wing spar that carries the wing, and a carriage disposed between the wing spar and the body to permit movement of the wing spar relative to the body. 10. The wing assembly of claim 1 wherein the first actuator is coupled to the moveable portion by a first carriage that permits linear movement of the moveable portion relative to the body. 11. The wing assembly of claim 10 wherein the first carriage includes a rack with teeth and a driven gear coupled to the first actuator and having teeth engageable with the teeth of the rack to move the rack relative to the first actuator. 12. The wing assembly of claim 10 wherein the first carriage includes a linear bearing having a first rail carried by the body and a second rail carried by the moveable portion and slideably coupled to the first rail to permit sliding movement of the moveable portion relative to the body. 13. The wing assembly of claim 1 wherein the second actuator is coupled to the wing by a second carriage. 14. The wing assembly of claim 13 wherein the second carriage includes a rack with teeth and a driven gear coupled to the second actuator and having teeth engageable with the teeth of the rack to move the rack relative to the second actuator. 15. The wing assembly of claim 13 wherein the second carriage includes a linear bearing having a first rail carried by the wing and a second rail carried by the moveable portion and slideably coupled to the first rail to permit sliding movement of the wing relative to the moveable portion. 16. The wing assembly of claim 14 which also includes a third actuator coupled to the rack to control pivoted movement of the wing. 17. The wing assembly of claim 1 wherein the first actuator is coupled to the moveable portion by a first carriage carried by said body to permit movement of the moveable portion relative to said body in a generally parallel direction to said longitudinal axis, and the second actuator is coupled to the wing by a second carriage attached to the wing and carried by the first carriage for conjoint movement therewith in response to movement of the first carriage, the second carriage being arranged for translation relative to the first carriage to allow the wing to move between fore and aft positions relative to the first carriage, and the second carriage is carried for pivoted movement relative to the first carriage to allow the wing to pivot relative to the first carriage. 18. A wing assembly for an aircraft, comprising: a wing having opposite wing tips; a first carriage attached to each of the wing tips; and a pair of second carriages arranged to carry the first carriages for conjoint linear movement of the wing with the second carriages in response to linear movement of the second carriages, the first carriages being arranged for translation relative to the second carriages to allow the wing to move between fore and aft positions relative to the second carriages, the first carriages being arranged for pivotal movement relative to the second carriages to allow the wing portion to pivot relative to the second carriages. 19. A wing assembly for an aircraft, comprising: a wing assembly including a wing spar and a wing carried by the wing spar for movement with and relative to the wing spar; a first actuator coupled to the wing spar to pivot the wing spar relative to the aircraft; a second actuator coupled to the wing to move the wing relative to the wing spar while permitting the wing to pivot relative to the second actuator and the wing spar. 20. The wing assembly of claim 19 wherein the second actuator includes a motor, a gear driven by the motor, and a rack driven by the gear and connected to the wing so that the wing moves with the rack and relative to the second actuator. 21. The wing assembly of claim 19 which also includes a pivot control feature that is coupled to the wing to at least selectively control the pivoted movement of the wing relative to the wing spar. 22. The wing assembly of claim 21 wherein the pivot control feature includes a third actuator that is connected to the rack to selectively pivot the wing. 23. The wing assembly of claim 21 wherein the pivot control feature is operable to limit or prevent pivoted movement of the wing relative to the wing spar.
