A hollow cooled airfoil includes an array of radially-spaced apart, longitudinally-extending partitions (122, 222) defining a plurality of cooling channels (124) therebetween. A plurality of aft pins (126, 226) are disposed in at least one of the cooling channels (124). Elongated turbulators (128, 228) are disposed in at least one of the cooling channels (124), and are oriented at an angle to a longitudinal axis of the vane such that an aft end (148, 248A, 248B) of each of the turbulators (128, 228) is closer to an adjacent partition than a forward end (146, 246B) of the turbulator (128, 228). The vane includes an array of radially-spaced apart, longitudinally-extending lands (134) and longitudinally-extending dividers (136) which define plurality of trailing edge slots (138, 238) therebetween. Each of the trailing edge slots (138, 238) has an inlet (140, 240) in fluid communication with a trailing edge cavity (114, 214) and an axially- downstream exit in fluid communication with the vane's trailing edge (150, 250). The dividers have an axial length less than an axial length of the lands. |
