Abstract
A swirler comprising an anti-rotation feature is provided. The swirler may be installed on a combustor within a gas turbine engine. The swirler may comprise a generally cylindrical profile. In this regard, the swirler may be configured to provide a generally uniform profile within the combustor. The swirler may comprise a floating collar with an anti-rotation feature. The swirler may also include a collar end plate that defines a slot that at least partially encloses the anti-rotation feature and minimizes rotational movement of the floating collar.
Claims13
A combustor, comprising:
- a fuel injector;
- a combustion chamber configured to receive fuel from the fuel injector;
- and
- a swirler comprising a floating collar comprising an anti-rotation feature and a collar end plate defining a notch;
- wherein the swirler is installable on the fuel injector;
- wherein the swirler is configured to deliver atomized fuel to the combustion chamber;
- wherein the notch is defined as a channel having four sides within the collar end plate;
- and
- wherein the swirler has a cylindrical profile and the anti-rotation feature does not protrude beyond the cylindrical profile of the swirler.
A gas turbine engine, comprising:
- a compressor,
- a turbine configured to drive the compressor;
- and
- a combustor configured to drive the turbine, the combustor comprising:
- an injector;
- a combustion chamber defined by the combustor and configured to receive fuel from the injector;
- and
- a swirler comprising a floating collar comprising an anti-rotation feature and a collar end plate defining a slot, the anti-rotation feature being retained within the slot;
- wherein the swirler is installed on the injector;
- wherein the swirler is configured to conduct and atomize fuel to the combustion chamber;
- wherein the slot is defined as a channel having four sides;
- and
- wherein the swirler has a cylindrical profile and the anti-rotation feature does not protrude beyond the cylindrical profile of the swirler.
A swirler, comprising:
- a housing defining a volume;
- a floating collar contained within the volume defined by the housing, the floating collar comprising an anti-rotation feature;
- and
- a collar end plate operatively coupled to the housing and configured to contain the floating collar within the volume;
- wherein the collar end plate defines a channel that is configured to receive the anti-rotation feature and to limit rotational movement of the floating collar;
- wherein the swirler has a cylindrical profile;
- wherein the channel is defined as a slot having four sides;
- wherein the anti-rotation feature does not protrude beyond the cylindrical profile of the swirler.
