| description | An airfoil for a gas turbine engine comprises an airfoil body having a first core cavity (1102) within the airfoil body and a second core cavity (1104) located within the airfoil body and adjacent the first core cavity, wherein the second core cavity is defined by a first cavity wall (1112), a second cavity wall (1114), a first exterior wall (1116), and a second exterior wall (1118), wherein the first cavity wall is located between the second core cavity. The first cavity wall includes a first surface (1124) angled toward the first exterior wall and a second surface (1126) angled toward the second exterior wall and at least one first cavity impingement hole (1120, 1122) is formed within the first surface. A funneling feature (1150, 1152) extends the second core cavity along the first exterior wall to funnel the first impingement flow along the first exterior wall, a core structure for manufacturing an airfoil for a gas turbine enginecomprises a first core cavity core and a second core cavity core to form first and second core cavities, at least one first cavity impingement stem extending between the first core cavity core and the second core cavity core to form a first cavity impingement hole, and a funnel feature extension extending from the second core cavity core in an aftward direction to form a funneling feature in a formed airfoil. |
