Abstract
A pressure bulkhead system is presented. The pressure bulkhead system comprises an aft pressure bulkhead having a bulkhead interface surface, skin splice angles positioned adjacent to one another and joined to the aft pressure bulkhead, and a plurality of shims between the flange surface and the bulkhead interface surface of the aft pressure bulkhead. The skin splice angles form a circumferential surface and a flange surface, wherein the circumferential surface has a nominal shape.

A pressure bulkhead system comprising:
- an aft pressure bulkhead having a bulkhead interface surface;
- skin splice angles positioned adjacent to one another and joined to the aft pressure bulkhead, wherein the skin splice angles form a circumferential surface and a flange surface, wherein the circumferential surface has a nominal shape;
- and
- a plurality of shims between the flange surface and the bulkhead interface surface of the aft pressure bulkhead.

A method for assembling a pressure bulkhead system, the method comprising:
- restraining skin splice angles adjacent to one another in a pressure bulkhead assembly support tool such that the skin splice angles form a circumferential surface with a nominal shape;
- scanning a flange surface of a flange formed by the skin splice angles restrained adjacent to one another in the pressure bulkhead assembly support tool to form a flange surface scan;
- aligning an aft pressure bulkhead having a bulkhead interface surface on the pressure bulkhead assembly support tool;
- scanning the bulkhead interface surface of the aft pressure bulkhead to form a bulkhead interface scan;
- determining gaps between the bulkhead interface scan and the flange surface scan;
- and
- joining the aft pressure bulkhead and the flange formed by the skin splice angles while a plurality of shims configured to fill the gaps is positioned between the flange surface and the bulkhead interface surface.
