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.
