DURABLE TURBINE VANE

摘要

A durable nozzle vane includes a leading edge(50) where hot combustion gas impinges on the vane, a pressure side (52) extending from the leading edge to a trailing edge (58) and a suction side (54) extending from the leading edge to the trailing edge, a blunt region (74) along the suction side between the leading edge and a high curvature region (72), the blunt region having small curvature in the length between the leading edge and the high curvature region allowing for at least two rows of cooling apertures (66).
