Abstract:
1. A turbine component comprising: an aft cooling circuit that extends between a turbine midsection and a turbine trailing end, the aft cooling circuit including a trailing end section proximate the trailing end, a first interior section proximate the turbine midsection, and a first intermediate section fluidly connected between the trailing end section and the first interior section; and a forward cooling circuit that extends between the turbine midsection and a turbine leading end, the forward cooling circuit including a leading end section proximate the leading end, a second interior section proximate the turbine midsection, and a plurality of second intermediate sections fluidly connected between the leading end section and the second interior section, wherein the leading end section includes a plurality of first coolant discharge openings, the plurality of second intermediate section includes a plurality of second coolant discharge openings, the first intermediate section includes a plurality of third coolant discharge openings, and the trailing end section includes a plurality of fourth coolant discharge openings, wherein a forward-most one of the plurality of second intermediate sections includes the plurality of second coolant discharge openings and the remaining one or ones of the plurality of second intermediate sections are free of any coolant discharge openings.
