Definitions

  • the invention relates to a window frame for installation in the exterior shell of an aircraft and to a method of manufacturing a downholder.
  • window frames made of aluminum which comprise a part which is made by forging, truing and cupping.
  • the component is organized into a total of three regions: an outer flange, an inner flange, and a vertical flange arranged perpendicular to and between these two flanges.
  • the window frames are typically connected with two rows of rivets over the outer flange with the aircraft structure or with the exterior shell of the aircraft.
  • a window element rests on the inner flange, which typically comprises two panes and a sealing arranged therebetween and which is fixed in its position via a downholder, also designated as a retainer, which is connected with the window frame.
  • the window frame may comprise an outer flange, an inner flange, and a vertical flange arranged perpendicular to and between the inner and the outer flanges.
  • the connection of the window frame to the aircraft structure may be realized by the outer flange.
  • a window element abuts against at least one of the inner and outer flanges. The window element is fixed into its position via a downholder connected with the window frame.
  • the downholder comprises or consists of a fiber-reinforced synthetic resin material.
  • a method in which a semifinished part made from web and thermoplastic material is made as a quasi-isotropic sheet material and this is transformed in a deep drawing process in the net shape of the downholder.
  • Fig. 1 shows a window frame in perspective view
  • Fig. 2 shows a detail section through the installation position of a window frame according to Fig. 1 ;
  • Fig. 3 shows a downholder in perspective view.
  • the downholder 10 is made by means of the so-called thermoplastic-deep drawing technology, in which, first, as a primary material, a semifinished part comprising reinforced web and thermoplastic in the form of a thin plate is produced, which next is deep drawn as quasi-isotropic sheet material.
  • the downholder 10 made in this manner which is shown in Fig. 3 in perspective view, has the same contour as a downholder made from aluminum, which also is designated as a retainer, but may have a substantially lower weight, which leads to an entire weight savings of approximately 20 percent compared to common window frames made completely from aluminum.
