  • Patent number: 6299109
    Abstract: There is disclosed a spoiler for wings, in particular of planes, which spoiler is unfoldable during the landing and take-off of the plane or the like and retractable during cruising. In order to provide for enhanced aerodynamic conditions during landing and taking off without deteriorating the aerodynamic conditions during cruising, a structural member preferably made of a composite material and, in particular, carbon fiber reinforced plastic is arranged on the trailing edge of the spoiler, viewed in the direction opposite to the flight direction. The structural member, during landing or taking off, in the unfolded state of the spoiler with the landing flaps extended reduces the gap formed between the trailing edge of the spoiler and the surface of the landing flap and, during cruising, with the landing flap pulled in and the spoiler retracted abuts on the surface of the landing flap.

  • Patent number: 5817409
    Abstract: Woven or non-woven fabric, in particular for the manufacture of prepregs especially for the manufacture of structural components in the aviation industry, manufactured of fibers, preferably carbon fibers having an elasticity modulus in excess of 80 000 N/mm.sup.2, preferably of 200 000 N/mm.sup.2 and a specific gravity of preferably 1,5 g/cm.sup.3, and not more than 2,1 g/cm.sup.3, wherein the fibers are composed of mono-filaments, and the fibers and therefore also the fabrics have been pressed flat, preferably calendered. In order to produce a woven or non-woven fabric which is mechanically particularly strong and yet can be manufactured economically, each fiber is composed of at least 2000, preferably 3000 individual mono-filaments (3K=200 tex=200 g/1000 m). The woven or non-woven fabric is preferably used for the manufacture of prepregs and henceforth for lightweight structural components especially for the aviation industry and in particular for overhead luggage compartments.
