Abstract: The present disclosure generally relates to integrated core-shell investment casting molds that provide tongue or groove structures corresponding, respectively, to groove or tongue structures in the surface of the turbine blade or stator vane, including in locations that are otherwise inaccessible. The groove and tongue structures also provide a pathway to restrict cooling flow between turbine blades to the flowpath.
