Abstract
A cooling system for a turbine airfoil of a turbine engine having a trailing edge cooling slot positioned within the generally elongated, hollow airfoil and extending from the trailing edge chordwise into the generally elongated, hollow airfoil toward the leading edge such that a secondary trailing edge is offset upstream from the trailing edge. As such, the trailing edge cooling slot reduces stress formation at the trailing edge of the turbine airfoil.
