<p>A turbine blade (10) includes an integral airfoil (18), platform (20), shank (22), and dovetail (24), with a pair of holes (36,38) in tandem extending through the platform and shank in series flow communication with an airflow channel (28) inside the shank. Cooling air discharged through the tandem holes effects multiple, convection, impingement, and film cooling using the same air. <IMAGE> <IMAGE></p> |
