Embodiment Construction

[0028] according to figure 1 , viewed in the longitudinal direction, the pressure fuselage of the aircraft consists of a plurality of fuselage sections 1a-1e, which are connected to each other at the borders by closed elliptical annular cross-sections in order to produce a long-shaped pressure fuselage. Between the fuselage section 1f forming the tail area and the adjacent fuselage section 1e, the tail-side pressure bulkhead 2 is fixed by means of a special bulkhead profile 5, said pressure bulkhead enclosing the pressure area inside the aircraft. 3 Separate from the unpressurized tail region, the pressure bulkhead is assigned to the fuselage section 1f. In the pressurized area 3 inside the aircraft there is a passenger cabin as well as a cargo space arranged below the passenger cabin.

[0029] In contrast, figure 2 A pressure nacelle constructed according to the so-called shell division concept is shown schematically. In addition to the traditional fuselage section 1 a fo...

Abstract

A pressure fuselage of an aircraft, which fuselage in longitudinal direction comprises several fuselage sections, wherein at least one rear dome-shaped pressure bulkhead is provided to form an aircraft-internal pressurized region, with a ring-shaped frame element profile being provided for radially outward attachment of said dome-shaped pressure bulkhead to at least one fuselage section, wherein the frame element profile on the side of the dome-shaped pressure bulkhead comprises a U-shaped profile section whose first end-side limb is attached towards the back on the dome-shaped pressure bulkhead by way of connecting means, and whose elongated radially outward extending second limb establishes a connection to the at least one fuselage section in such a manner that it is possible for the connecting means to be installed solely from the aircraft-internal pressurized region.

Description

technical field [0001] The invention relates to a pressure fuselage of an aircraft, which is composed in the longitudinal direction of a plurality of fuselage sections, in which at least one tail-side pressure bulkhead is provided for forming a pressure zone inside the aircraft , for the radially outer fastening of the pressure bulkhead to at least one fuselage section, an annular frame profile is provided. Background technique [0002] The field of application of the invention extends in particular to civil aircraft technology. For the transport of people and cargo, civil aircraft with large-volume fuselages that can be divided in several planes are generally used. Therefore, in addition to the wrap-around fuselage construction, there is also a fuselage construction associated with the so-called shell division concept. The fuselage of the latter aircraft forms a force-bearing structure. Furthermore, in the fuselage shell, longitudinally acting forces and torsional forces...
