摘要
An airfoil component having a body having a leading edge and a trailing edge, a ceramic casting insert for making the component and the method for making the component. The component includes an internal cooling passageway and an elongated opening in communication with the internal cooling passageway. The opening is configured with a geometry that provides structural stability during casting and has a cross-section that sufficiently restricts airflow through the opening to provide efficient component operation. The casting insert includes outer edge projections and a web portion corresponding to the geometry of the openings when cast around the insert. The method includes casting the airfoil component around the casting insert and removing the insert to provide the component having the openings.
