Claim 10:
11. A gas turbine engine comprising:
a compressor section;
a combustor in fluid communication with the compressor section; and
a turbine section in fluid communication with the combustor,
the turbine section having a turbine airfoil that includes
an airfoil section including an airfoil wall defining a leading end, an arced trailing end, and first and second sides joining the leading end and the arced trailing end, the first and second sides spanning in a longitudinal direction between first and second ends, the airfoil wall circumscribing an internal core cavity, the internal core cavity including an exit region that spans from the first and second ends and that opens through the arced trailing end, the exit region including pedestals arranged in a plurality of longitudinal pedestal rows that extend from the first end to the second end, the pedestals within each of the longitudinal pedestal rows are equidistantly spaced apart, wherein at least one of the longitudinal pedestal rows is straight such that the pedestals are aligned along a straight line and at least one of the longitudinal pedestal rows is arced such that the pedestals are aligned along a continuous arc.
