    Abstract: A turbine blade airfoil assembly includes a cooling air passage. The cooli ng air passage includes a plurality of impingement openings that are isolated from at least one adjacent impingement opening. The cooling air passage is formed an d cast within a turbine blade assembly through the use of a single core. The single core forms the features required to fabricate the various separate and isolated impingement openings. The isolation and combination of impingement openings provides for the augmentation of convection and film cooling and provide the flexibility to tailor airflow on an airfoil to optimize thermal performance of an airfoil.

    Abstract: A turbine blade airfoil assembly (12) includes a cooling air passage (30). The cooling air passage (30) includes a plurality of impingement openings (32) that are isolated from at least one adjacent impingement opening (32). The cooling air passage (30) is formed and cast within a turbine blade assembly through the use of a single core (44). The single core (44) forms the features required to fabricate the various separate and isolated impingement openings (32). The isolation and combination of impingement openings provides for the augmentation of convection and film cooling and provide the flexibility to tailor airflow on an airfoil to optimize thermal performance of an airfoil.

    Abstract: A cast vane cluster (32) with enhanced cooling contains an inner and an outer platform (34, 36) and at least two airfoils (38) for directing a primary fluid stream axially rearward . A duct (56) is bounded by inner and outer endwall surfaces (40, 44), and adjacent airfoil fluid directing surfaces. One or more cooling holes (62) in the duct are drilled using an electrodischarge machine (EDM) method without a line of sight from the drilling equipment to the cooling hole location. One or more cooling holes (62), located in portions of the duct, may not be visible when viewed from an external location. Additionally, one or more cooling holes (62) may only have an outlet cross sectional ar ea (66) visible when viewed along a longitudinal axis from an external location.
