Pressure fuselage of an aircraft with dome-shaped pressure bulkhead

A pressure fuselage of an aircraft, comprising:

• a forward fuselage section and a rear fuselage section, said fuselage sections arranged along a longitudinal direction of the fuselage,
• a rear dome-shaped pressure bulkhead for forming an internally pressurized region in the aircraft forward of the dome-shaped pressure bulkhead, and
• a ring-shaped frame for attachment of the outer circumference of said dome-shaped pressure bulkhead to at least one of the fuselage sections;
• wherein the ring-shaped frame has a cross-section comprising a first limb, a second limb, a base, and a cross-piece;
• wherein said first limb extends in a primarily radial direction relative to the center of the ring-shaped frame from a proximal end to a distal end;
• wherein said second limb extends in a primarily radial direction relative to the center of the ring-shaped frame from a proximal end to a distal end, wherein the distal end of the second limb is farther from the center of the ring-shaped element than the distal end of the first limb;
• wherein said base extends in a primarily longitudinal direction relative to the fuselage, and extends from the proximal end of the first limb to the proximal end of the second limb;
• wherein the cross-piece extends in a longitudinal direction relative to the fuselage from a forward end to a rear end, and is connected to the distal end of the second limb at a location between said forward end and aft end;
• wherein the first limb is configured to be attached to the dome-shaped pressure bulkhead by at least one fastener, in such a manner that it is possible for the at least one fastener to be installed solely from the internally pressurized region of the aircraft;
• and
• wherein at least one of said fuselage sections is attached to the cross-piece of the ring-shaped frame.
