Abstract

A core is provided for fabricating a blade to include an airfoil (220). The airfoil (220) includes pressure and suction surfaces (221, 222), leading and trailing edges (223, 224) extending along the pressure and suction surfaces (221, 222) and a tip shelf (225) with a first sweep configuration (701) and a wall (226, 310). The core includes channel sections configured to form internal channels (702) within the airfoil (220) by casting processes and tip rods extending from respective portions of the channel sections proximate to a tip shelf (225) location. The respective portions of the channel sections have a second sweep configuration (430) corresponding to the first sweep configuration (701). The tip rods are configured to extend through the wall (226, 310) at an angle of about 5-12 degrees inclusive relative to a normal angle of the wall (226, 310) during the casting processes to form through-holes angled at about 5-12 degrees inclusive in the wall (226, 310).
