Abstract

Claims (15)

1. A bulkhead panel for a combustor, comprising:

a plurality of bulkhead panel segments formed of a ceramic matrix composite, the plurality of bulkhead panel segments extending radially between an outer combustor panel and an inner combustor panel, wherein each bulkhead panel segment comprises:

an outer flange extending axially from an outer diameter of each bulkhead panel segment and aft from and past an interior surface of each bulkhead panel segment;

an inner flange extending axially from an inner diameter of each bulkhead panel segment and aft from and past the interior surface of each bulkhead panel segment;

an outer spacer located between an exterior surface of the outer flange of each bulkhead panel segment 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; and

an inner spacer located between an exterior surface of the inner flange of each bulkhead panel segment 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.

2. The bulkhead panel of claim 1 , wherein each bulkhead panel segment defines a swirler opening, and wherein the ceramic matrix composite extends continuously and without interruption from the swirler opening to an outer perimeter of each bulkhead panel segment.

3. The bulkhead panel of claim 2 ,

wherein the outer spacer is attached to the outer flange and configured to apply a first biasing force against the outer flange in a radially inward direction; and

wherein the inner spacer is attached to the inner flange and configured to apply a second biasing force against the inner flange in a radially outward direction.

4. The bulkhead panel of claim 3 , wherein the outer flange is coupled to a combustor outer shell and wherein coupling the outer flange of each bulkhead panel segment to the combustor outer shell comprises compressing the outer spacer between an exterior surface of the outer flange and the interior surface of the outer combustor panel coupled to the combustor outer shell.

5. The bulkhead panel of claim 4 , wherein the outer spacer is coupled to the first forward end of the outer combustor panel.

6. The bulkhead panel of claim 3 , wherein the inner flange is coupled to a combustor inner shell and wherein coupling the inner flange of each bulkhead panel segment to the combustor inner shell comprises compressing the inner spacer between an exterior surface of the inner flange and the interior surface of the inner combustor panel coupled to the combustor inner shell.

7. The bulkhead panel of claim 6 , wherein the inner spacer is coupled to the second forward end of the inner combustor panel.

8. The bulkhead panel of claim 2 , wherein each bulkhead panel segment is configured to extend 360° about an engine central longitudinal axis.
