Abstract

A turbine airfoil 150, 176, 200 includes a body 210 having an airfoil wall, and a coolant chamber 216 within the body 210. A plurality of cooling passages 204 are within the airfoil wall, each cooling passage 204 includes: a first portion 218 extending from a first point 220 on an exterior surface 222 of the airfoil wall to the coolant chamber 216, and a second portion 230 extending from a second point 232 on the exterior surface 222 of the airfoil wall distal from the first point 220 to intersect a mid-portion 234 of the first portion 218. A cap element 250 closes the first portion 218 at the first point 220 but leaving the second portion 230 open. Each cooling passage 204 has a single inlet 252 in fluid communication with the coolant chamber 216 and a single outlet 254 at the second point 232 of the second portion 230.
