Abstract
An aft frame assembly for a gas turbine transition piece includes a main body having an upstream facing surface and a downstream facing surface. A plurality of feed hole inlets are located on the upstream facing surface. The feed hole inlets are coupled to a plurality of cooling channels that pass through the main body towards the downstream facing surface. A plurality of plenums are located in or near the downstream facing surface, and each cooling channel is connected to and terminates in one of the plenums. The cooling channels are inputs to the plenums. A plurality of microchannel cooling slots are formed in or near the downstream facing surface, and each microchannel cooling slot is connected to one of the plenums. The microchannel cooling slots are outputs of the plenums. Two or more cooling channels and two or more microchannel cooling slots are connected to one of the plenums.
