Problems solved by technology

Since the pressure difference between the pressure chamber and the outside air fluctuates violently every time the flight altitude changes, especially during take-off and landing, the bending moments transmitted to the skin correspondingly cause cyclic variable deformation of the skin, and leading to material fatigue

Embodiment Construction

[0028] In the drawings, unless otherwise indicated, like reference numerals designate identical or functionally identical components.

[0029] figure 1 Internal perspective view of details of the shell for the fuselage. The skin 120 of the shell is reinforced on its inner surface 204 by stringers 124 extending in the longitudinal direction of the aircraft and by conformal strips 308 extending perpendicular thereto along the perimeter of the fuselage.

[0030] The pressure bulkhead 100 , which subdivides the fuselage in an airtight manner along an inner contour 108 into an inner pressure zone 102 and an outer pressure zone 104 , is located in the region of the shown detail. For example, the inner pressure zone 102 is constituted by a pressure chamber 102 including the passenger cabin, the cargo compartment and the cockpit, while the outer pressure zone 104 is a space 104 located eg at the rear of the aircraft, behind the pressure chamber 102 and for accommodating auxiliary tra...

Abstract

The present invention provides a pressure bulkhead for subdivision of an aircraft or spacecraft into an internal-pressure area and an external-pressure area. The pressure bulkhead comprises a pressure plate which has a rim which is shaped corresponding to an internal contour of the aircraft or spacecraft, a supporting device which supports the rim such that it can be tilted on the inner contour, and a seal which seals the rim with the internal contour. A further aspect of the invention provides a method for subdivision of an aircraft or spacecraft into an internal-pressure area and an external-pressure area. First of all, a pressure plate is provided which has a rim which is shaped to correspond to an internal contour of the aircraft or spacecraft. In further steps, the rim is supported such that it can be tilted on the internal contour, and is sealed with the internal contour.

Description

technical field [0001] The invention relates to pressure bulkheads for subdividing aircraft or spacecraft. The invention further relates to a structural component and to an aircraft or spacecraft having a pressure bulkhead of this type, and also to a method for subdividing an aircraft or spacecraft. Background technique [0002] Although applicable to the subdivision of any desired means of transport or container, the invention and the problems underpinning it will be described in detail below with respect to the aft pressure bulkhead of an aircraft. [0003] In aircraft flying at very high altitudes, such as modern commercial aircraft, the passenger cabin, cockpit and cargo compartment are usually designed as airtight compartments in which an air pressure greater than the external pressure can be maintained during flight and Allowing passengers and crew to survive without the need for oxygen masks or similar respirators. In order to isolate this type of pressure compartme...
