Abstract
An industrial engine turbine stator vane with a three-pass aft flowing serpentine cooling circuit and turn channels formed outside of the endwalls that connect adjacent legs of the serpentine flow circuit. A ceramic core used to cast the vane includes dual print-outs extending from the turn channel forming pieces that provide a more rigid core structure to prevent core shift or movement during casting. The dual core print-outs form purge air holes for the rim cavity that is then covered with cover plates if purge air holes are not required.
