1. An integrated combustor nozzle, comprising:
a combustion liner extending radially between an inner liner segment and an outer liner segment, the combustion liner including a forward end portion, an aft end portion, a first side wall, and a second side wall, the aft end portion of the combustion liner defining a turbine nozzle, the combustion liner defining a cavity forward of the turbine nozzle, the cavity extending between the first side wall and the second side wall, wherein a first rib and a second rib extend from one of the first side wall or the second side wall and within the cavity, the first rib and the second rib axially spaced apart such that the cavity is partitioned into a forward cavity portion, a middle cavity portion, and an aft cavity portion, and wherein the first rib and the second rib define one or more openings such that the forward cavity portion, the middle cavity portion, and the aft cavity portion are in fluid communication;
a fuel injector having an inlet disposed within the middle cavity portion, the fuel injector extending through one of the first side wall or the second side wall; and
an impingement cooling apparatus positioned within the aft cavity portion, the impingement cooling apparatus comprising:
a flange;
a plurality of impingement members each extending from a respective opening defined in the flange to a respective closed end, each impingement member including an impingement wall and a solid wall spaced apart from the impingement wall, wherein each impingement member defines a plurality of impingement apertures that direct air to impinge upon one of the first side wall and the second side wall, wherein the inlet of the fuel injector receives post-impingement air from the aft cavity portion; and
stand-offs extending from each impingement member of the plurality of impingement members, the stand-offs spacing apart each impingement member of the plurality of impingement members from surrounding surfaces.
