Abstract

A fuselage section of an aircraft has an inner surface with a non-circular contour. A pressure bulkhead for use in the fuselage section has a non-circular outer edge that is aligned with the non-circular contour of the inner surface of the fuselage section. The pressure bulkhead has a spherically-shaped inner section having radially arranged stiffening units and a non-spherically outer section having additional radially arranged stiffening units; the stiffening units corresponding to each section do no extend into the other section. The pressure bulkhead is attached to the fuselage section. A method of manufacturing a fuselage section having such a pressure bulkhead is also provided.
