Definitions

  • the present invention relates to an aircraft window lightened with low drag, that is to say which, under the effect of the pressurization of the interior volume of the aircraft in flight, does not deform while forming compared to the aircraft body
  • the inner slab keeps the interior volume of the aircraft under a desired pressure. Even if the interior slab (or the peripheral seal with which it is in contact) is commonly provided with a small through hole making it possible to maintain the air space under the pressure of the interior volume of the aircraft in flight under normal conditions , this inner slab is able to maintain this interior volume of the airplane under the desired pressure in flight in the event of rupture of the outer slab, because this hole is sufficiently small; in this case, a hissing sound may occur.
  • PMMA poly (methyl methacrylate)
  • Document US 2015/047275 A1 describes an airplane window composed of a monolithic inner slab of polymer material and of a laminated outer slab of glass separated by an air gap, but not the constructive characteristics of the laminated outer slab.
  • monolithic polymer thick and heavy, could be replaced by a lighter glass laminate, the constituents of which could be selected so that, under flight conditions, the outer surface of the laminate conforms to the curvature of the cabin of the surrounding plane.
  • the invention relates to an airplane window composed of a slab
  • the outer laminated slab consists of two sheets of glass bonded by means of a layer interlayer adhesive, in that the thickness of the outer glass sheet is 0.2-2.6mm, and the thickness of the inner glass sheet is 0.2-2.1mm.
  • the constituents of the outer laminated glass slab, in particular the glass sheets, are selected and dimensioned in order to obtain in particular a bending stiffness of the outer slab such that, under the effect of the pressurization of the interior volume of the aircraft in flight , the curvature of the outer surface of this slab is substantially the same as that of its mounting environment (aircraft cabin), guaranteeing the best aerodynamics of the whole.
  • the terms “interior (s)”, “exterior (s)” refer here to the interior and exterior of the aircraft.
  • the outer surface of the window in contact with the air is made of glass, which is advantageous compared to a material such as poly (methyl methacrylate) (PMMA) or equivalent which, directly abraded by air friction, loses good optical transparency qualities, unlike glass, requiring after a certain number of flight hours to repolish the PMMA.
  • PMMA poly (methyl methacrylate)
  • laminated glass allows the integration of an intermediate adhesive layer with an acoustic damping function, as will be seen in more detail in the embodiments below.
  • SPD Suspended Particle Device -, electrochromic
  • Some of these layers, in particular metallic, can be formed in patterns or patterns with holes without a layer, capable of allowing the passage of GSM, 3G, 4G, 5G and equivalent waves.
  • the structure of the window of the invention also facilitates the integration of antennas
  • the monolithic inner slab is made of a polymer material comprising a poly (methyl methacrylate) (PMMA), a polycarbonate (PC) alone or in mixtures or copolymers of several of them.
  • PMMA poly (methyl methacrylate)
  • PC polycarbonate
  • the thickness of the outer glass sheet is between 1.6 and 2.4 mm, and the thickness of the inner glass sheet is between 0.4 and 1.9 mm.
  • the laminated outer slab comprises glass sheets of chemically reinforced glass, of soda-lime, aluminosilicate or borosilicate nature.
  • the total glass thickness of the laminated outer slab is between 1.5 and 5 mm, preferably between 2 and 4.5 mm.
  • the laminated outer slab comprises at least one intermediate adhesive layer chosen from a polyvinyl butyral (PVB), optionally with an acoustic damping property, a thermoplastic polyurethane (TPU), an ethylene-vinyl acetate copolymer (EVA), or a glass ionomer .
  • PVB polyvinyl butyral
  • TPU thermoplastic polyurethane
  • EVA ethylene-vinyl acetate copolymer
  • glass ionomer glass ionomer
  • the main surface of the laminated outer slab opposite the monolithic inner slab is flat or convex with less curvature than that of the surrounding aircraft structure, so that flight, under the effect of the pressurization of the interior volume of the airplane, said main surface of the laminated outer slab has a curvature substantially identical to that of the structure of the surrounding airplane.
  • the step of shaping / bending the glass sheets constituting the laminate is advantageously dispensed with.
  • the air gap is at the pressure of the interior volume of the aircraft; this is achieved for example, as indicated above, by a small through hole in the monolithic interior slab or its mounting gasket.
  • FIG.1 is a partial schematic sectional view of the aircraft window of the invention in the mounting position; the proportions of the dimensions of the constituents are not exact.
  • the window comprises a monolithic inner slab 1 made of poly (methyl methacrylate) (PMMA) or polycarbonate (PC) with a thickness of between 2.5 and 12 mm, for example of PMMA of 4 mm thick, and a laminated outer glass slab 2 separated by an air gap 3.
  • PMMA poly (methyl methacrylate)
  • PC polycarbonate
  • outer glass sheet 4 / interlayer adhesive 6 / inner glass sheet 5 Several laminated outer slab compositions 2 according to the invention are given below, in the order: outer glass sheet 4 / interlayer adhesive 6 / inner glass sheet 5:
  • the glass used is chemically reinforced, of soda-lime, aluminosilicate or borosilicate nature.
  • PVB polyvinylbutyral
  • - Acoustic PVB acoustic tri-layer polyvinylbutyral, marketed by the Sekisui Company under the registered trademark S-LEC® Sound Acoustic Film, or by the Kuraray Company under the registered trademark Trosifol® Acoustic, in various thicknesses.
  • the monolithic inner slab 1 and the laminated outer slab 2 are identical.
  • window structures in particular those of the laminated outer glass slab 2 mentioned above, make it possible to lighten the window while avoiding excessive protuberance deformation in flight, which is unfavorable from an aerodynamic point of view.
