Claim 0:
1. An assembly for a turbine engine with a flowpath, comprising:
a combustor comprising a tubular inner wall, a tubular outer wall, an annular bulkhead, an annular cowl, a combustion chamber and a cowl plenum, the annular bulkhead axially between and separating the combustion chamber and the cowl plenum, the combustion chamber extending radially between the tubular inner wall and the tubular outer wall, the cowl plenum extending radially between opposing inner and outer sides of the annular cowl;
a swirler including a plurality of vanes located at an inlet into the combustion chamber, the plurality of vanes of the swirler arranged fluidly between the cowl plenum and the combustion chamber along the flowpath;
a fuel injection system including a first fuel injector and a second fuel injector;
the fuel injection system configured to provide the first fuel injector with first fuel and provide the second fuel injector with second fuel, the first fuel comprising ammonia, and the second fuel different than the first fuel and comprising hydrogen gas;
the first fuel injector configured to direct the first fuel into the cowl plenum upstream of the plurality of vanes of the swirler for subsequent combustion in the combustion chamber; and
the second fuel injector configured to direct the second fuel into the flowpath at the inlet into the combustion chamber downstream of the plurality of vanes of the swirler for subsequent combustion in the combustion chamber.
