A hinge sealing element to substantially prevent airflow between an edge of a moveable aero surface structure and an edge of a fixed skin of an aircraft wing in the vicinity of the ribs to which the moveable aero surface structure is pivotally mounted is disclosed. The hinge sealing element comprising a deformable elongate, resiliently flexible strip having an upper face to contact a trailing edge of a fixed skin and one end attachable to a moveable aero surface structure such that said strip extends from an upper surface of said moveable aero surface structure beyond its leading edge and into a space between the edge of the fixed skin and the rib of the aircraft wing to a second, free end. The strip is configured such that it deforms during pivotal movement of the moveable aero surface structure to maintain contact between the upper face of the flexible element and the trailing edge of the fixed skin.

1. An aircraft hinge sealing element comprising a deformable elongate, and resiliently flexible strip, said strip having an upper face to contact a trailing edge of a fixed skin of an aircraft wing and one end attached to a moveable aero surface structure, said surface structure pivotally mounted on a rib of said aircraft wing, said surface structure having a leading edge, wherein said strip extends from an upper surface of said surface structure beyond said leading edge and into a space between the trailing edge of the fixed skin and the rib of the aircraft wing, said strip ending at a second, free end, the strip configured to deform during pivotal movement of the surface structure to maintain contact between the upper face of the flexible strip and the trailing edge of the fixed skin and substantially prevent airflow in said space. 2. A hinge sealing element according to claim 1, formed from plastic. 3. A hinge sealing element according to claim 1, formed from metal. 4. A hinge sealing element according to claim 3, formed from a high chromium heat treated stainless steel. 5. A hinge sealing element according to claim 1, formed from a composite material. 6. An assembly including the hinge sealing element according to claim 1, to substantially prevent airflow between said leading edge of said moveable aero surface structure and said trailing edge of said fixed skin of said aircraft wing in the vicinity of the rib to which the moveable aero surface structure is pivotally mounted. 7. An assembly according to claim 6, wherein the assembly comprises a guide element mountable on an upper surface of said rib to guide sliding movement of the hinge sealing element in said space during pivotal movement of the moveable aero surface structure. 8. An assembly according to claim 7, wherein the guide element comprises a roller mounted for rotation in a supporting structure on the upper surface of said rib, said roller positioned to contact the underside of the hinge sealing element. 9. An assembly according to claim 6, comprising a cap attached to the free end of the hinge sealing element to reduce friction between the sealing element and the fixed wing where the free end of the hinge sealing element contacts the fixed wing during pivotal movement of the moveable aero surface structure. 10. An assembly according to claim 7, wherein the guide element comprises an elongate channel member on the upper surface of the rib, said channel configured to slideably receive the free end of the hinge sealing element. 11. An assembly according to claim 10, wherein the channel member comprises a guide pin positioned so that the sealing element slides into the channel beneath the guide pin. 12. An assembly according to claim 6, wherein the fixed wing includes a secondary sealing element protruding from said trailing edge, said secondary sealing element is biased into contact with an upper surface of the hinge sealing element forming a sliding seal therebetween. 13. A wing for an aircraft including the assembly according to claim 6, including said fixed wing portion and a moveable aero surface structure pivotally mounted to said fixed wing portion. 14. A wing according to claim 13, wherein said moveable aero surface structure is a spoiler. 15. A wing according to claim 13, wherein said moveable aero surface structure is an aileron. 16. A wing according to claim 13, wherein said moveable aero surface structure is a flap hinge fairing.
