1. A gas turbine engine comprising:
a compressor section and a combustion section in serial flow arrangement along an engine centerline, the combustion section comprising:
a combustor liner;
a dome wall coupled to the combustor liner, and a dome inlet located in the dome wall, wherein the dome wall defines a conic portion forming an obtuse angle with the combustor liner;
a fuel injector fluidly coupled to the dome inlet, wherein the dome wall extends radially between the fuel injector and the combustor liner to define a flat portion, wherein the flat portion and the conic portion meet at a first junction;
a flare cone disposed around the fuel injector, wherein the flare cone meets the conic portion at a second junction and wherein the conic portion extends between the first junction and the second junction;
a combustion chamber fluidly coupled to the fuel injector and defined at least in part by the combustor liner and the dome wall; and
at least one set of dilution openings located in the dome wall and fluidly coupled to the combustion chamber, the at least one set of dilution openings circumferentially arranged about the engine centerline;
wherein the at least one set of dilution openings forms one of a segmented annulus about a circumference of the engine centerline or an annulus about the circumference of the engine centerline.
