STAGGERED CROSSOVERS FOR AIRFOILS

摘要

An airfoil includes an airfoil section having an external wall and an internal wall (690). The internal wall (690) defines a first reference plane (663) extending in a spanwise direction and through a thickness of the internal wall (690). A first cavity (682) and a second cavity (684) are separated by the internal wall (690). A plurality of crossover passages (686) within the internal wall (690) connects the first cavity (682) to the second cavity (684). The plurality of crossover passages (686) are arranged such that the passage axis (687) of each of the plurality of cooling passages (686) intersects a surface of the second cavity (684).
