Abstract
A combustor for a gas turbine system includes an additively manufactured (AM) combustor body including a one-piece member. The member includes a combustion liner including a transition portion, and an aft frame at an aft end of the transition portion. The aft frame includes an inner end integral with the combustion liner, an outer end configured to couple to a turbine inlet casing, and a circumferentially extending passage defined partially within the inner end. A plurality of circumferentially spaced ribs extends forward from the inner end of the aft frame on an exterior surface of the transition portion. A flow sleeve is integral with the circumferentially spaced ribs. The AM combustor body includes a plurality of parallel, sintered metal layers. The circumferentially extending passage, the spaced ribs and the flow sleeve promote increased convection and conduction cooling to the aft frame without loss of structural strength.
