Abstract:
1. A turbine engine component comprising: an airfoil portion having an airfoil mean line, a pressure side, and a suction side; a first region on said pressure side having a first array of cooling microcircuits embedded in a wall forming said pressure side; a second region on said pressure side having a second array of cooling microcircuits embedded in said wall; and said first region being located on a first side of said mean line and said second region being located on a second side of said mean line; a trailing edge internal circuit within said airfoil portion; said first array having a first cooling circuit with a first inlet located on said first side of said mean line, said first inlet receiving cooling fluid from said trailing edge internal circuit; said second array having a second cooling circuit with a second inlet located on said second side of said mean line, said second inlet receiving cooling fluid from said trailing edge internal circuit; and said trailing edge circuit having a plurality of holes for supplying fluid to a passageway having a plurality of openings to cool the trailing edge of the airfoil portion and a plurality of feed holes for supplying fluid to said first and second inlets.
