Abstract

An airfoil section (66) has an airfoil wall (68) that defines a leading end (68a), a trailing end (68b), and first and second sides (68c, 68d) that join the leading end (68a) and the trailing end (68b). The airfoil wall (68) circumscribes an internal core cavity (70). A skincore passage (74) is embedded in the first side (68c) of the airfoil wall (68) between inner and outer portions (76, 78) of the first side (68c) of airfoil wall (68). The skincore passage (74) defines a passage forward edge (74a) and a passage aft edge (74b). The first side (68c) of the airfoil wall (68) has a portion (86) that tapers in thickness at the passage aft edge (74b). A cooling passage (80) is embedded in the second side (68d) of the airfoil wall (68) between inner and outer portions (82, 84) of the second side (68d) of airfoil wall (68). The inner portion (82) of the second side (68d) of the airfoil wall (68) includes a protrusion (88) located across the internal core cavity (70) from the portion (86) of the first side (68c) that tapers in thickness.
