Definitions

  • the invention relates to a floor structure for aircraft according to the preamble of claim 1.
  • the floor structures usually consist of the floor cross members with the seat rail profiles attached to them
  • the floor cross members in the upper deck of the Airbus A380 were built in CFRP and the floor panels in CFRP sandwich structures.
  • this type of construction does not use the specific properties of the fiber composite material; In the first step, it merely represents a material substitute for the metallic solution.
  • Manufacturing effort and assembly is particularly suitable for use in aircraft construction.
  • Fig. 1 schematically shows a cross section through an element according to the invention
  • FIG. 2a schematically shows a longitudinal section of a first exemplary embodiment with integrated cross member elements
  • FIG. 2b schematically shows a longitudinal section of a second exemplary embodiment with integrated transverse and longitudinal support elements
  • FIG. 3 shows a cross section through an element according to the invention and its connection to the aircraft fuselage
  • Fig. 5 is a perspective view of the floor structure according to the invention from above, and
  • FIG. 6 shows a view of the floor structure according to the invention with integrated additional longitudinal support elements from below.
  • Fig. 1 shows schematically a cross-section through a floor element according to the invention, specifically seen transversely to the aircraft fuselage.
  • the base plate 1 is provided with integrated cross members 2. The further details are omitted.
  • 2a schematically shows a longitudinal section of a first exemplary embodiment with integrated transverse support elements 2.
  • FIG. 2b schematically shows a longitudinal section of a second exemplary embodiment with integrated transverse and longitudinal support elements 2 and 3, respectively.
  • the floor therefore consists of a continuous cover plate 1 per section.
  • the integrated cross members 2 for absorbing the bending forces from the floor loads are located directly below this cover plate.
  • the structural characteristics can only be used in Be transverse support substructures 2 or be in transverse and longitudinal support structures 2 and 3, respectively.
  • the floor slab structure 1 is designed in such a way that it absorbs the "upper chord forces" of the cross members 2.
  • the dimensioning thickness of the uppermost skin of the fiber composite structure is thus determined by the compressive forces from bending and not by the compressive forces from the load from point loads, such as shoe heels .
  • FIG 3 the connection to the supporting structure of the aircraft fuselage is shown.
  • the floor cross members are connected to the frames 9 by conventional connecting elements 4 and 5 and by telescopic rods 8.
  • recesses 1 a for the seat rails 6 are provided in the base plate 1.
  • the latter are preferably made of metal, with titanium being preferred for weight reasons. They are expediently laid in the already built-in floor.
  • Inflatable silicone tubes can be used to form the stiffener geometries.
  • FIGS. 4 and 5 additionally show three-dimensional views of the elements already described and, in particular, their juxtaposition to form a floor.
  • FIG. 6 shows a view from below with longitudinal support elements 3 and a cable trough 7.
  • the integrated floor structure represents a fiber composite construction that is optimal in terms of cost and weight, which also saves considerable time when assembling the sections.

Abstract

L'invention concerne une structure de plancher pour aéronefs comprenant des supports de plancher, ainsi que des rails de siège et des panneaux de plancher qui sont disposés sur ces supports de plancher. Selon l'invention, le plancher est constitué d'éléments comprenant une plaque de recouvrement continue (1) dans laquelle les supports de plancher (2, 3) sont intégrés, et les rails de siège (6) encastrés. De plus, lesdits éléments (1, 2, 3) sont configurés pour recevoir des charges de sol ainsi que des charges de flexion transversale et longitudinale. La structure de support intégrée des éléments (1, 2, 3) est produite conformément à une technique de production, à partir d'un matériau composite renforcé par des fibres, au cours d'un cycle de procédé. La structure selon l'invention présente une configuration d'ensemble particulièrement légère, sa constitution composite renforcée par des fibres se prête à la production, ce qui entraîne des avantages financiers élevés, et les frais de montage peuvent en outre être économisés.
