Abstract:
1. A gas turbine airfoil comprising: a pressure sidewall and a suction sidewall joined along respective leading and trailing edges and extending radially outward from an inner diameter to a outer diameter; a plurality of suction side flow channels extending chordwise within the suction sidewall and having respective heights selected to achieve a desired degree of cooling for the suction sidewall; a plurality of pressure side flow channels extending chordwise within the pressure sidewall and having respective heights selected to achieve a desired degree of cooling for the pressure sidewall; wherein a combined height of the suction side flow channels and the pressure side flow channels is greater than an available height along the trailing edge; and a transition region in each flow channel wherein the height of the channel is reduced to an outlet height so that respective outlets of the flow channels can each be independently disposed in the trailing edge.
