Airfoil cooling passageway turn and manufacturing method therefore

摘要

An internally-cooled turbomachine element (140) has an airfoil extending between inboard and outboard ends. A cooling passageway (150) is at least partially within the airfoil and has at least a first turn (162). Means (240) are in the passageway (150) for limiting a turning a loss of the first turn (162). The turbomachine element may result from a reengineering of an existing element configuration lacking such means.
