Abstract
A fluid conduit may be provided comprising a ceramic matrix composite (CMC) cross-over tube and a flange. The CMC cross-over tube may comprise a first end configured to extend into a first combustor liner of a gas turbine engine, and a second end configured to extend into a second combustor liner of a gas turbine engine. The interior of the CMC cross-over tube may define a passageway. The flange may extend outwardly from an outer surface of the CMC cross-over tube. The flange may be configured to engage at least one of the first combustor liner and the second combustor liner.
Claims20
A fluid conduit comprising:
- a ceramic matrix composite (CMC) cross-over tube comprising a first end configured to extend into a first combustor liner of a gas turbine engine and a second end configured to extend into a second combustor liner of the gas turbine engine, wherein an interior of the CMC cross-over tube defines a passageway;
- and
- a flange extending outwardly from an outer surface of the CMC cross-over tube, wherein the flange is configured to engage at least one of the first combustor liner and the second combustor liner.
A combustor system, comprising:
- a combustion chamber comprising a combustor liner;
- a ceramic matrix composite (CMC) cross-over tube having a first end and a second end, the first end extending into the combustion chamber through the combustor liner, wherein an interior of the CMC cross-over tube defines a passageway extending from the first end to the second end;
- and
- a flange extending radially from the CMC cross-over tube between the first end and the second end, wherein the flange is configured to engage the liner.
A method of manufacturing a fluid conduit, comprising:
- providing a porous ceramic preform in a shape of a tube;
- and
- forming the ceramic preform into a ceramic matrix composite (CMC) cross-over tube, the CMC cross-over tube comprising a first end configured to extend into a first combustion chamber and a second end configured to extend into a second combustion chamber, wherein an inner surface of the CMC cross-over tube defines a passageway configured to allow fluid communication between the first combustion chamber and the second combustion chamber.
