Embodiment Construction

[0016] Depending on the configuration of the bulkhead, the pressure bulkhead of an aircraft, such as the aft pressure bulkhead, has certain requirements imposed on the structure. For example, dome-shaped diaphragms have load distribution benefits and lower structural weight than diaphragms of a flatter configuration. On the other hand, the flatter configuration of the plenum bulkhead generally requires a heavier construction and more complex support system, but allows aircraft systems to pass through the bulkhead structure more easily. The apparatus and methods described herein advantageously take advantage of the benefits of these various separator configurations.

[0017] refer to figure 1 , the aircraft 10 includes an empennage section 12 positioned in a rear end or side 14 of the aircraft 10 . A pressure bulkhead 16 is located within the aircraft 10 to provide sealed separation of the rear or unpressurized side 14 of the aircraft 10 from the forward or pressurized side 1...

Abstract

The invention relates to a pressurized bulkhead. A pressure bulkhead for an aircraft includes a wall assembly. The wall assembly includes a first wall section which extends in a direction nonparallel to a length of the aircraft. The wall assembly further includes a second wall section secured to the first wall section wherein the second wall section includes a curved shape. The curved shape includes a convex portion which extends further along the length of the aircraft in a direction toward the aft end of the aircraft than the first wall section. A method for assembling a pressure bulkhead is also provided.

Description

technical field [0001] The present invention relates to pressure bulkheads for aircraft, and more particularly to pressure bulkheads with structural support. Background technique [0002] The pressure bulkhead of an aircraft, in particular the aft pressure bulkhead, is usually dome-shaped. The domed shape has the ability to distribute the loads imposed on the domed structure into membrane loads effective to the fuselage structure. However, a disadvantage of this domed or hemispherical partition is that it is difficult to route the system through the partition if the partition has a curved shape. Sending the system through a dome-shaped bulkhead involves added design complexity due to the additional structure required to provide a flat surface for system attachment. Flatter bulkheads provide easier interfaces for aircraft systems such as electrical, hydraulic and fuel systems, as well as other systems within the aircraft. Moreover, due to the longitudinally extending natur...
