ABSTRACT:
A cooled vane for a gas turbine engine in which the coolant channels have an arcuate component, convex outwardly towards the surface of the vane to establish centrifugal force in the coolant flowing therethrough and thereby induce a secondary flow to the coolant, promote mixing and reduce the outer boundary layer of the coolant to enhance the heat transfer characteristics to the coolant and thereby more efficiently maintain the vane within acceptable temperature limitations.
