Insulation package arrangement for insulating the interior of an aircraft fuselage

Abstract

according to an exemplary embodiment, which may be installed near the fuselage structure, is believed protect the cabin region of an aircraft against fire whose flames act on the insulation package from outside the aircraft environment, thus clearly facilitating evacuation of the passangers from the vehicle. The insulation package arrangement may comprise several fuselage insulation packages (19-22) of an elongated form. These packages may adjoin the aircraft fuselage structure in the direction of the longitudinal axis (9) of the aircraft. They may longitudinally adjoin a support surface (31a) of the stringers (31) which are attached to the aircraft fuselage, or longitudinally adjoin an inner area (33a) of a panel of outer skin and are attached to both longitudinal sides of the ribs (32). Furthermore those insulation packages (19-22) may be completely enclosed by a burn-through-proof foil (11) which is arranged in a space enclosed by interior paneling and by the panels of the outer skin. The design of a fuselage insulation package may be implemented with burn-throughproof insulation of a larger cross section and / or a burn-through-proof barrier layer of a smaller cross section which are arranged within the fuselage insulation package either singly or in combination. In this arrangement, the insulation or the barrier layer extends near to or adjacent to an interior wall region of the foil wall. As an alternative only that insulation which on the longitudinal end of the fuselage insulation package continues outward with a flat insulation end section is atteched outside of and adjacent to the foil (11) circumference of the fuselage insulation package (19-22). Said end section of insulation is attached to a rib-attachment region which is arranged below the respective longitudinal sides of a rib (32) and near the stringer (31) by means of burn-through-proof attachment elements (4, 13).

[0001] Cross References to Related Applications [0002] This application claims priority from DE 10 2004 001 049, filed 5 January 2004, and US 60 / 600,106, filed 9 August 2004, both of which are incorporated herein by reference. technical field [0003] The invention relates to an insulation, such as a fire or fire protection, for an aircraft. In particular, the present invention relates to insulation encapsulation for isolating the interior of an aircraft fuselage. Background technique [0004] A conventional isolation system is known, as shown in Fig. 1 , which generally comprises a core material and an isolation material embedded in an isolation package, and also includes an envelope. The core material and insulating material may comprise products of the fiber industry, in particular for which glass fiber material (glass wool) is widely used. This material satisfies the considered thermal and acoustic insulation requirements quite well. In order to install (attach) the...

[0007] Furthermore, traditional isolation attachments are made of non-metallic materials (plastics), which may melt in a fire

Thus, it is always desirable to prolong the fire resistance time of the attachment and keep the insulation in place to prevent the (burning) insulation (insulation package) from falling - such a fall would cause uncontrolled damage inside the aircraft. obstacle
