US Patent 12012198 Pressure bulkhead

A rear pressure bulkhead comprising a dome shaped structure, and a set of built-in extension components (“petals”) homogeneously distributed along the periphery of the dome-shaped structure. This results in the dome-shaped structure being secured to a frame of the aircraft, while the extension components are secured to longitudinal structures of the aircraft. An aircraft rear fuselage is provided including such a rear pressure bulkhead so that the available cabin space, i.e., pressurized space, is extended without enlarging the fuselage.
