Gas turbine combustor dome with integrated flare swirler

A swirler assembly for a gas turbine engine, the swirler assembly defining a swirler assembly centerline therethrough, a longitudinal direction along the swirler assembly centerline, a radial direction extending outward from the swirler assembly centerline, and a circumferential direction about the swirler assembly centerline, the swirler assembly comprising:

• a swirler having a primary swirler and a secondary swirler, the secondary swirler being disposed longitudinally downstream of the primary swirler along the swirler assembly centerline;
• a flare connected to a downstream end of the secondary swirler, the flare including (i) a flare axial wall extending circumferentially about the swirler assembly centerline and extending in the longitudinal direction, the flare axial wall having a flare axial wall outer surface, and (ii) a flare conical wall connected at a downstream end of the flare axial wall and extending circumferentially about the swirler assembly centerline, and extending radially outward and longitudinally downstream from the downstream end of the flare axial wall, the flare conical wall having a flare conical wall outer surface, wherein the flare axial wall outer surface and the flare conical wall outer surface define a flare outer surface;
• and
• a dome disposed radially outward of the flare, the dome including (i) a dome axial wall extending circumferentially about the swirler assembly centerline and extending in the longitudinal direction, the dome axial wall having a dome axial wall inner surface, (ii) a dome conical wall connected at a downstream end of the dome axial wall and extending circumferentially about the swirler assembly centerline, and extending radially outward and longitudinally downstream from the downstream end of the dome axial wall, and (iii) a dome radial wall extending radially outward from a downstream end of the dome conical wall, the dome conical wall having a dome conical wall inner surface, wherein the dome axial wall inner surface and the dome conical wall inner surface define a dome inner surface,
• wherein a flare oxidizer flow passage is defined by the flare outer surface and the dome inner surface, and
• wherein the flare oxidizer flow passage includes a swirl inducing member therewithin that induces a swirled flow of an oxidizer passing through the flare oxidizer flow passage into a combustion chamber.
