A deployment system for deploying a moveable wing surface (22) from a main wing section (8). The deployment system includes a plurality of swing arm assemblies (24,26) connecting the moveable wing surface (22) to the main wing section (8) and a drive means for deploying and retracting the moveable wing surface (22), wherein at least one of the swing arm assemblies (24,26) includes a swing arm (28) pivotably connected to the main wing (8) and a connector mechanism (34) for connecting the movable wing surface (22) to the swing arm (28). The connector mechanism (34) includes a first joint (36) having at least first and second rotational degrees of freedom and a second joint (40) having at least first and second rotational degrees of freedom and at least first and second translational degrees of freedom, said connector mechanism (34) being arranged to provide, in use, rotation of the moveable wing surface (22) about its longitudinal axis during deployment of the moveable wing surface (22), and allowing relative movement between the moveable wing surface (22) and the main wing section (8) due to thermal expansion and contraction of the movable wing surface (22).

1. A swing arm assembly for displacing an associated moveable wing surface relative to an associated wing section, the associated moveable wing surface having a longitudinal axis, said swing arm assembly comprising:a swing arm member having a first mounting portion supported on the associate wing section, and second and third mounting portions supporting the associated moveable wing surface;a first connector arrangement extending between said first mounting portion and the associate wing section, said first connector arrangement having at least a first rotational degree of freedom;a second connector arrangement extending between said second mounting portion and the associated moveable wing surface, said second connector arrangement having at least first and second rotational degrees of freedom; and,a third connector arrangement extending between said third mounting portion and the associated moveable wing surface, said third connector arrangement having at least first and second rotational degrees of freedom and at least a first translational degree of freedom.2. A swing arm assembly according to claim 1, wherein said second mounting portion is spaced a first distance from said first mounting portion and said third mounting portion is spaced a second distance from said first mounting portion.3. A swing arm assembly according to claim 2, wherein said first distance is greater than said second distance.4. A swing arm assembly according to claim 1, wherein at least one of said first, second and third mounting portions includes first and second spaced-apart tabs.5. A swing arm assembly according to claim 4, wherein at least one of said first, second and third connector arrangements includes a pivot member having an axis and supported between said first and second spaced-apart tabs of said at least one of said first, second and third mounting portions.6. A swing arm assembly according to claim 5, wherein at least one of said first, second and third connector arrangements includes a connecting member supported on said pivot member.7. A swing arm assembly according to claim 6, wherein said connecting member is displaceable along said axis between said first and second spaced-apart tabs.8. A swing arm assembly according to claim 7, wherein said displacement of said connecting member is due to one of sliding movement of said connecting member along said pivot member and sliding movement of said pivot member relative to said first and second spaced-apart tabs.9. A swing arm assembly according to claim 1, wherein said second and third connector arrangements each include a first pivot member, a connecting member supported on said first pivot member, and a second pivot member respectively extending from said connecting member substantially perpendicular to said first pivot member.10. A swing arm assembly according to claim 9, wherein said second pivot member of at least one of said second and third connector arrangements is adapted for lost motion movement.11. A swing arm assembly according to claim 1, wherein said swing arm member has a longitudinally extending centerline and said first translational degree of freedom of said third connector arrangement is in a direction substantially perpendicular to said centerline.12. A swing arm assembly according to claim 1, wherein said third connector arrangement has a second translational degree of freedom.13. A swing arm assembly according to claim 12, wherein said second translational degree of freedom of said third connector arrangement is in a direction substantially parallel to a longitudinal axis of the associated moveable wing surface.14. A swing arm assembly according to claim 13, wherein said third connector arrangement is adapted to provide lost motion movement in alignment with said second translational degree of freedom.15. A swing arm assembly according to claim 1, wherein said first rotational degree of freedom of at least one of said first, second and third connector arrangements is about a pivot axis extending substantially perpendicular to said centerline axis of said swing arm member.16. A swing arm assembly according to claim 1, wherein said second rotational degree of freedom of at least one of said second and third connector arrangements is about an axis that is in substantial alignment with a longitudinal axis of the associated moveable wing surface.17. A deployment system adapted to deploy and retract an associated moveable wing surface respectively to and from an associated wing section, said deployment system comprising:a plurality of swing arm assemblies interconnected between the associated moveable wing surface and the associated wing section, at least one of said plurality of swing arm assemblies including a swing arm and a connector mechanism, said swing arm having a longitudinal axis and being pivotably connected to the associated wing section, said connector mechanism interconnecting the associated moveable wing surface and said swing arm; and,a drive system engaging at least one of said plurality of swing arm assemblies and operable to displace at least one of said plurality of swing arm assemblies to deploy and retract the associated moveable wing surface;said connector mechanism including a first joint and a second joint, said first joint having at least first and second rotational degrees of freedom, said second joint having at least first and second rotation degrees of freedom and at least first and second translational degrees of freedom.18. A deployment system according to claim 17, wherein said first swing arm assembly has a first length and said second swing arm assembly has a second length.19. A deployment system according to claim 18, wherein said first length is greater than said second length.20. A deployment system according to claim 17, wherein said drive system includes a linkage interconnecting at least two of said plurality of swing arm assemblies.
