1. A rear fuselage of an aircraft comprising:
a rear pressure bulkhead comprising:
a dome-shaped structure, and
a set of built-in extension components distributed along a periphery of said dome-shaped structure,
wherein the dome-shaped structure comprises a ring-shaped attachment area configured to secure the dome-shaped structure either to a circumferential frame of the aircraft or to another circumferential structure, and
wherein the extension components comprise attachment means configured to secure each extension component to a longitudinal structure of the aircraft,
at least one circumferential frame comprising at least a portion, the portion comprising a first foot, a first web and an angled head, the angled head being configured to accommodate the dome-shaped structure of the rear pressure bulkhead so that the dome-shaped structure rests thereon,
wherein the dome-shaped structure is secured to the angled head via the ring-shaped attachment area, and
a set of longitudinal structures correspondent in number and distribution with the set of built-in extension components of the rear pressure bulkhead,
wherein each of the longitudinal structures comprises a head configured to accommodate an extension component so that said extension component rests thereon,
wherein the extension component is secured to the head via the attachment means.
