Abstract

Airfoils (400) and core assemblies for such airfoils are described. The airfoils (400) include a leading edge cavity (410) defined, in part, by a leading edge interior rib (422) and a trailing edge cavity (412) defined, in part, by a trailing edge interior rib (434). A plurality of pressure side cavities (416a-d) are defined by pressure side skin cavity walls (426) with at least one pressure side skin cavity wall (426) not extending to the suction side wall (408). A plurality of suction side cavities (418a-d) are defined by suction side skin cavity walls (428) with at least one suction side skin cavity wall (428) not extending to the pressure side wall (406). A main body cavity (414) extends between the leading edge interior rib (422) and the trailing edge interior rib (434) and the plurality of side cavities (416a-d, 418a-d) are arranged in a staggered pattern to define the bounds of the main body cavity (414).
