Pressure fuselage of an aircraft with dome-shaped pressure bulkhead

1. 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.

2. The pressure fuselage of claim 1 , further comprising a plurality of tension struts arranged so as to be spaced apart from each other along the circumference of the dome-shaped pressure bulkhead, which tension struts by first ends thereof are attached to the dome-shaped pressure bulkhead and to the ring-shaped frame by way of the at least one fastener.

3. The pressure fuselage of claim 2 , wherein each of the plurality of tension struts is configured as a metal strip of adequate tensile strength, said metal strip comprising on first end regions thereof at least one opening for receiving the at least one fastener.

4. The pressure fuselage of claim 1 , wherein the cross-piece of the ring-shaped frame interconnects the fuselage sections.

5. The pressure fuselage of claim 1 , further comprising rivets for attachment of the at least one fuselage section to the cross-piece of the ring-shaped frame.

6. The pressure fuselage of claim 1 , wherein the fuselage in a pressurized region comprises longitudinally divided first and second shell halves.

7. The pressure fuselage of claim 6 , wherein the ring-shaped frame is configured in first and second parts, wherein each frame part forms a ring segment of 180°.

8. The pressure fuselage of claim 1 , wherein the ring-shaped frame is configured as a single part, thus forming a full ring of 360°.

9. The pressure fuselage of claim 1 , wherein the ring-shaped frame comprises a milled part made from light metal.

10. The pressure fuselage of claim 1 , further comprising a plurality of longitudinally extending stringers forming a static node by way of first and second stringer coupling components arranged on forward and rear sides of the ring-shaped frame, respectively.

11. The pressure fuselage of claim 10 , further comprising a gap sealing tape applied on the inside on the outer shell of the adjacent fuselage section, wherein the cross-piece of the ring-shaped frame is applied in a gap-bridging manner, and wherein the end regions of the first and second stringer coupling components are applied inside and outside the pressurized region, respectively.
