A method for assembly of a combustor, comprising:
- locating a bulkhead panel over an interior surface of a bulkhead shell;
- locating a swirler through a swirler opening defined by the bulkhead panel and through a shell opening defined by the bulkhead shell;
- coupling a combustor inner shell to an inner flange of the bulkhead panel by compressing an inner spacer between an exterior surface of the inner flange and an interior surface of an inner combustor panel coupled to the combustor inner shell, wherein the inner flange of the bulkhead panel extends axially and aft from an inner diameter of the bulkhead panel;
- coupling a combustor outer shell to an outer flange of the bulkhead panel by compressing an outer spacer between an exterior surface of the outer flange and an interior surface of an outer combustor panel coupled to the combustor outer shell, wherein the outer flange of the bulkhead panel extends axially and aft from an outer diameter of the bulkhead panel;
- and
- coupling a hood to the combustor outer shell and the combustor inner shell.
