Aircraft fuselage

Abstract

The fuselage is conceived in such a way as to prevent the spread of flames produced by a source of fire and acting on the fuselage from outside the aircraft environment. The fuselage concept takes into account materials or material combinations that will scarcely allow protection of the cabin area of an aircraft (upon emergency landing) to be violated by flames spreading from outside the aircraft environment, which may facilitate an evacuation of passengers from the aircraft. An aircraft fuselage, whose fuselage structure , in addition to other structural elements that are components of the mechanic al strength bracing of the fuselage and help absorb its forces, encompasses an exterior skin (2) consisting of various respective materials, which are designed to be resistant to shear, and incorporated as a bearing element int o the mechanical strength bracing (6,7,8) to absorb and transfer the forces an d torques acting thereupon. The exterior skin (2) is fabricated from a burn- through resistant semi-finished material consisting of a non-metallic materi al or a fireproof metallic material, wherein the semi-finished material can be molded through further processing. Also, the exterior skin may be realized b y a semi-finished material combining a non-metallic material and a metallic material, wherein the produced exterior skin product is a hybrid material th at can be molded and joined through further processing.

Background technique [0004] Aluminum structures have been used very successfully in aircraft construction in the past. Without looking further into this fact, any expert and probably even a layman interested in aircraft construction knows that the conventional structural design of an airframe includes an outer fuselage skin made solely of aluminum or an aluminum alloy. The prior art provides relevant examples. [0005] Some accidents, the causes of which, unfortunately, have been found to be caused by kerosene leaks from aircraft performing emergency landings. Accordingly, there may be a need to improve the fire performance of aircraft. [0006] When a fire occurs during an emergency landin...

Problems solved by technology

This proposal, in addition to only providing insufficient fire protection for the isolated enclosure and the interior areas of the fuselage, due to the fact that in the event of a fire the flames of the fire pass right from the outside of the aircraft through the damaged outer skin and reach them a short time later Internal partitions, i.e. (only) fire-resistant and not fire-resistant membranes that also pass through prolonged exposure to fire, the original piece-by-piece arrangement of only fire-resistant membranes will not ensure adequate protection against the interior areas of the fuselage fire protection level
