Abstract
Official abstract text for this publication.
An aircraft fuselage includes at least one space arranged in the aircraft fuselage and at least one wall. The wall resists burnthrough for a period of at least four minutes from outside the aircraft fuselage towards the space, wherein the region of the aircraft fuselage underneath the space does not include burnthrough-resistant insulation. The space may be a cargo compartment of the aircraft or a passenger cabin, while the wall may be designed as a cargo compartment floor, passenger cabin floor or wing/fuselage fairing (belly fairing). The design of the aircraft fuselage results in burnthrough resistance that meets the requirements of FAR §25.856 (b) without any additional burnthrough-resistant insulation in the aircraft fuselage.
First claim
Opening claim text (preview).
The invention claimed is: 1. An aircraft fuselage, comprising: at least one space; a floor arranged in the aircraft fuselage; and a fairing of a transition between a wing and the aircraft fuselage; wherein the fairing is configured to prevent flame penetration therethrough for a period of at least four minutes from outside the aircraft fuselage towards the space; and wherein a region of the space of the fuselage immediately above the fairing does not include an insulation configured to prevent flame penetration therethrough for a period of at least four minutes. 2. A wing-fuselage fairing or belly fairing of an aircraft, comprising: a wall configured to prevent flame penetration therethrough into an aircraft fuselage for a period of at least four minutes. 3. The wing-fuselage fairing or belly fairing of claim 2 , wherein the wall is made from carbon fibre materials or glass fibre materials in the form of at least one woven-fabric structures, laminates, or sandwich structures.
