Carrying or guiding device for aircraft components
A carrying or guiding device for aircraft components, in particular for landing flaps arranged on an aircraft wing, including a carrier having a substantially U-shaped section with substantially parallel side walls, and a cover plate arranged at the open side. To minimize weight, facilitate manufacture and mounting, and provide sufficient strength, the carrier and the cover plate are made of fiber reinforced plastic, in particular of carbon fiber (CF) reinforced plastic. The connection between the carrier and the cover plate and any possible connecting elements is preferably provided by gluing and, possibly, by additional rivet or screw connections.
1. An aircraft component carrying or guiding device comprising:
a carrier having a substantially U-shaped section with an open side, and substantially parallel side walls, said carrier being made of fiber reinforced plastic and said side walls each having a plurality of openings respectively aligned with corresponding openings in the other side wall;
a cover plate provided substantially at said open side of the carrier; and
a plurality of connecting elements for a connection to other structural elements, said connecting elements being arranged between the side walls of the carrier and in alignment with said aligned side wall openings, said connecting elements also being made of fiber reinforced plastic.
2. The device according to claim 1 , wherein free ends of the side walls are provided with projecting flanges.
3. The device according to claim 1 , wherein stiffening structures are arranged on the side walls of the carrier.
4. The device according to claim 1 , wherein the fiber reinforced plastic is carbon fiber reinforced plastic (CFRP).
5. The device according to claim 1 , wherein the side wall openings are generally circular and said connecting elements are formed by tubular elements having lateral flanges that extend over adjacent edges of said openings.
6. The device according to claim 3 , wherein the stiffening structures and/or connecting elements and/or the cover plate are connected with the carrier by gluing.
7. The device according to claim 6 , wherein additional connectors including rivets or screws are provided in addition to the gluing.
8. The device according to claim 7 , wherein the carrier and/or the stiffening structures and/or the connecting elements and/or the cover plate have holes at the sites of the additional connectors.
9. The device according to claim 5 , wherein the carrier has thickened portions on said edges.
10. The device according to claim 1 , wherein the carrier has thickened portions at sites of connection to other structural elements.
11. The device according to claim 1 , wherein said carrier includes fastening or adapter elements made of metal.
12. The device according to claim 11 , wherein the fastening or adapter elements are connected to the carrier via corresponding counter pieces.
13. The device according to claim 3 , wherein the cover plate and/or said stiffening structures are made of fiber reinforced plastic.
14. The device according to claim 13 , wherein said fiber reinforced plastic is carbon fiber reinforced plastic (CFRP).
15. The device according to claim 1 , wherein the carrier, the connecting elements and the cover plate are made of plastics material according to the resin transfer molding (RTM) method.
16. The device according to claim 15 , wherein the carrier, the connecting elements and the cover plate contain carbon fabric for reinforcement purposes.
17. The device according to claim 16 , wherein nylon is sewn or woven into the carbon fabric.
18. An aircraft component carrying or guiding device comprising:
a carrier made of fiber reinforced plastic having a substantially U-shaped section with an open side, and substantially parallel side walls, free ends of the side walls having projecting flanges and each of said side walls having at least one generally circular opening;
a cover plate provided substantially at said open side of the carrier and configured to be connected to said flanges; and
a plurality of generally tubular connecting elements made of fiber reinforced plastic and extending between the side walls of the carrier so as to be spaced from said flanges, at least one of said tubular connecting elements extending between said side wall openings.
19. The device according to claim 18 , wherein said side walls each have a plurality of openings respectively aligned with corresponding openings in the other side wall, each of said tubular connecting elements extending between a respective pair of aligned openings to provide a hollow passageway open on each side and extending through said U-shaped section.
20. The device according to claim 19 , wherein said tubular elements have lateral flanges that extend over adjacent edges of said openings on outer surfaces of said side walls.
