Embodiment Construction

[0018] The figure shows a detail of a fuselage skin 2 formed from several suitable fuselage sections 1a, 1b for the pressure-resistant fuselage of an aircraft, including an approximately conical tapering tail. According to the invention, the fuselage section 1 a comprises a fuselage shell structure 4 made of fiber composite material and a pressure bulkhead 6 formed integrally with the fuselage shell structure 4 . The approximately spherical pressure bulkhead 6 (spherical pressure cap) is curved and protruded toward the tail of the fuselage, and forms a tail end of a pressure-resistant ventilation area of ​​the aircraft fuselage. The transition zone from the fuselage shell structure 4 to the pressure bulkhead 6 extends continuously without sharp bends that would distort the fiber orientation, and the transition zone is fairly flat in such a way as to avoid Unfavorable right angles. Since the pressure bulkhead 6 is integrally formed with the fuselage section 1a, a weight-optimi...

Abstract

A fuselage section (1a) is disclosed for the pressure fuselage of an aircraft having a fuselage shell structure (4) and at least one pressure bulkhead (6) composed of a composite fibre material, wherein the pressure bulkhead (6) is formed integrally with the fuselage shell structure (4). A fuselage shell (2) having at least one such fuselage section (1a) is also disclosed.

Description

technical field [0001] The invention relates to a fuselage section of a pressure fuselage for an aircraft, comprising a fuselage skin structure and at least one pressure bulkhead made of fiber composite material, and to a fuselage skin for an aircraft , including at least one fuselage section of this type. Background technique [0002] Currently, pressure fuselages for aircraft are generally assembled from fuselage sections and pressure bulkheads forming the ends of pressure-treated flight units. Traditionally, these pressure bulkheads have been produced in different structures and subsequently integrated into the corresponding fuselage sections. Disadvantages of the different constructions are the large number of parts and the high production costs, resulting in a high structural weight. [0003] In order to reduce the number of parts, it is known to have a pressure bulkhead for an aircraft comprising a pressure fuselage. For example, European Patent Application Publicat...
