Abstract: A device is disclosed for preventing gases and/or fluids emanating from a wing box of an aircraft from passing to an aircraft fuselage cell situated underneath it. The device comprises at least one sheet-like material positioned below or above the wing box. The sheet-like material is preferably made of a woven fabric comprising aramid fibers or the like, which fabric in order to ensure the required seal vis-à-vis liquid and/or gaseous substances, in particular vis-à-vis fuels, has been impregnated or soaked with an epichlorohydrin elastomer compound or with some other elastomer, for example a rubber compound or the like.

Abstract: A sealing assembly is provided in an airframe of aircraft. The sealing assembly includes, but is not limited to a resilient and yet stiff enough bellows body that is attachable to the fuselage of the aircraft and is further attachable to a center wing box of the aircraft. The sealing assembly seals off a gap between the fuselage and the center wing box so as to allow maintaining pressure in the fuselage if the fuselage is pressurized. The bellows body is a composite and is designed to sustain exposure to tear and wear and exposure to a high and low temperatures as well as exposure to chemicals used during operation of the aircraft.

Abstract: The invention relates to a device for preventing gases and/or fluids emanating from a wing box 2 of an aircraft from passing to an aircraft fuselage cell situated underneath it. According to the invention the device comprises at least one sheet-like material 13 positioned below or above the wing box 2. The sheet-like material 13 is preferably made of a woven fabric comprising aramid fibers or the like, which fabric in order to ensure the required seal vis-à-vis liquid and/or gaseous substances, in particular vis-à-vis fuels, has been impregnated or soaked with an epichlorohydrin elastomer compound or with some other elastomer, for example a rubber compound or the like. As a result of the design-related slidability of the sheet-like material 13 parallel to the longitudinal axis of the fuselage cell of the aircraft, during installation the possibility of compensating for tolerances in this direction is provided.
