Extended bulkhead panel
A combustor may comprise an outer combustor panel and an inner combustor panel radially inward of the outer combustor panel. A bulkhead panel may extend radially between the outer combustor panel and the inner combustor panel. An outer spacer may be located between an outer flange of the bulkhead panel and the outer combustor panel. An inner spacer may be located between an inner flange of the bulkhead panel and the inner combustor panel.
1. A method for assembly of a combustor, comprising:
locating a bulkhead panel over an interior surface of a bulkhead shell, the bulkhead panel extending radially between an outer combustor panel and an inner combustor panel, the bulkhead panel including an outer flange and an inner flange, wherein the outer flange extends axially from an outer diameter of the bulkhead panel and aft from and past an interior surface of the bulkhead panel, and wherein the inner flange extends axially from an inner diameter of the bulkhead panel and aft from and past the interior surface of the bulkhead panel;
locating an outer spacer between an exterior surface of the outer flange of the bulkhead panel and an interior surface of the outer combustor panel, wherein a first forward end of the outer combustor panel is located in a first groove defined by the outer spacer;
locating an inner spacer between an exterior surface of the inner flange of the bulkhead panel and an interior surface of the inner combustor panel, wherein a second forward end of the inner combustor panel is located in a second groove defined by the inner spacer;
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 the inner flange of the bulkhead panel;
coupling a combustor outer shell to the outer flange of the bulkhead panel; and
coupling a hood to the combustor outer shell and the combustor inner shell.
2. The method of claim 1 , wherein coupling the combustor inner shell to the inner flange of the bulkhead panel comprises compressing the inner spacer between the exterior surface of the inner flange and the interior surface of the inner combustor panel coupled to the combustor inner shell.
3. The method of claim 2 , wherein coupling the combustor outer shell to the outer flange of the bulkhead panel comprises compressing the outer spacer between the exterior surface of the outer flange and the interior surface of the outer combustor panel coupled to the combustor outer shell.
4. The method of claim 3 , further comprising:
coupling the inner spacer to the second forward end of the inner combustor panel; and
coupling the outer spacer to the first forward end of the outer combustor panel.
5. The method of claim 3 , wherein the bulkhead panel comprises a plurality of arcuate bulkhead panel segments.
