1. A combustor comprising:
a cylindrical combustion liner having an inlet end, an outlet end, and a central axis, the combustion liner defining a combustion chamber; and
a fuel injector assembly positioned radially outward of the cylindrical combustion liner relative to the central axis, the fuel injector assembly comprising:
an annular body defining:
a hollow interior space;
first and second openings to the interior space, wherein the first and second openings are respectively proximate opposite first and second ends of the annular body, the first end being upstream of the second end;
an upstream flange defining the first opening; and
a chamber defining a fluid manifold;
an annular fuel nozzle defining a cavity therein and positioned in the interior space and spaced from the annular body and the cylindrical combustion liner, the annular fuel nozzle being airfoil shaped in section and comprising a leading edge proximate the first end, a trailing edge proximate the second end of the annular body, and a plurality of fuel injection ports,
wherein said trailing edge comprising a channel defined therein and said plurality of fuel injection ports extend from the cavity to the channel; and
one or more fuel supply struts coupled to the annular fuel nozzle and the annular body,
wherein the one or more fuel supply struts are coupled in fluid communication with the fluid manifold and the annular fuel nozzle.
