  • Patent number: 9764845
    Abstract: A module for sealing an interface between compartments of a pressurized cabin of an aircraft. The module comprises a frame, a sheet and a rigid structure. The frame includes an opening surrounded by attachment surfaces. The frame is connected or connectable to a support structure of the aircraft. The sheet is attached to the attachment surfaces of the frame for sealing the at least one opening. The rigid structure is attached to the sheet within the frame without contacting the frame so that a displacement of the rigid structure relative to the frame induces tensile stress in the sheet between the frame and the rigid structure.

  • Publication number: 20110284689
    Abstract: The present invention relates to an aircraft cabin panel for sound reduction in an interior space. The invention in particular also relates to an aircraft comprising an interior lining with sound-absorbing and sound-reducing panels. In order to provide a panel that is optimized in terms of the design space required by it and in terms of its weight, for use in aircraft, which panel provides improved sound reduction and sound absorption characteristics, an aircraft cabin panel for sound reduction in an interior space is provided, which aircraft cabin panel in at least one region comprises a sandwich construction with a core layer, a first covering layer and a second covering layer. The core layer comprises sound absorbing open-pore core material. The first and the second covering layer are connected to the core layer in a planar fashion. The first covering layer is arranged towards the sound waves to be absorbed and the second covering layer is arranged opposite the first covering layer.

  • Publication number: 20110100747
    Abstract: A sandwich element for sound-absorbing inner cladding of means of transport, especially aircraft, comprising a three-dimensionally constructed core disposed between two substantially parallel cover layers is provided. Sound transmission passages are incorporated in the core, and/or in at least one cover layer. At least one sound absorption layer is in the area of a cover layer at least in parts. Passages in the cover layers and core provide good sound absorption and heat insulation. The passages allow transmission of sound. The through channels and the preferably inclined installation of the sandwich element allow foreign bodies to be flushed out by, for example, a cleaning liquid or condensation. Possibly sufficient sound absorption can be achieved without the sound absorption layer. Ventilation of the core prevents the long-term presence of condensation, which could cause corrosion and/or rotting. A fire-retardant layer including metal particles may increase fire protection and electromagnetic insulation.

  • Patent number: 7837007
    Abstract: A sound absorption element for means of transport, in particular for aircraft, comprising at least one sound absorption panel arranged on a base panel with the base panel comprising a multitude of recesses, in particular a hole grid or the like, for the transmission of sound. According to the invention, the sound absorption panels are each framed by a frame, wherein on the at least one frame at least in some sections a transition profile, in particular to prevent fatigue fractures due to stepwise changes of rigidity between the at least one frame and the base panel is arranged. Due to the base panel comprising a multitude of recesses, in particular comprising a hole grid, in connection with the sound absorption panels an air-permeable sound absorption element can be achieved.
