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.
Claims12
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 wherein the CMC cross-over tube is longitudinally positioned about a longitudinal axis;
- and
- a flange extending radially away from the longitudinal axis and outwardly from an outer surface of the CMC cross-over tube, wherein the flange comprises:
- a first surface configured to engage the first combustor liner;
- a second surface configured to engage the second combustor liner;
- a radially outer edge relative to the longitudinal axis;
- and
- a plurality of channels comprising:
- a first channel arranged on the first surface and configured to facilitate fluid flow of fluid between the first surface and the first combustor liner from the radially outer edge to the outer surface of the CMC cross-over tube;
- a second channel arranged on the second surface and configured to facilitate fluid flow of fluid between the flange and the second combustor liner from the radially outer edge to the outer surface of the CMC cross-over tube.
A combustor system, comprising:
- a first combustion chamber comprising a first combustor liner;
- a second combustion chamber comprising a second combustor liner;
- a ceramic matrix composite (CMC) cross-over tube having a first end and a second end, the first end extending into the first combustion chamber through the first combustor liner, the second end extending into the second combustion chamber through the second combustor liner, wherein an interior of the CMC cross-over tube defines a passageway extending from the first end to the second end, and wherein the CMC cross-over tube is longitudinally positioned about a longitudinal axis;
- and
- a flange extending radially from the CMC cross-over tube between the first end and the second end, wherein the flange comprises:
- a first surface configured to engage the first combustor liner;
- a second surface configured to engage the second combustor liner;
- a radially outer edge relative to the longitudinal axis;
- and
- a plurality of channels comprising:
- a first channel arranged on the first surface and configured to facilitate fluid flow of fluid between the first surface and the first combustor liner from the radially outer edge to the outer surface of the CMC cross-over tube;
- and
- a second channel arranged on the second surface and configured to facilitate fluid flow of fluid between the second surface and the second combustor liner from the radially outer edge to the outer surface of the CMC cross-over tube.
