A turbine blade (10) includes forward and aft serpentine cooling circuits (2-4,5-7) terminating in corresponding forward and aft impingement channels (1,8). Each serpentine circuit (2-4,5-7) has two metered inlets (54-60) for distributing primary inlet flow to the first passes (4,5) thereof and supplemental inlet flow to the last passes (2,7) thereof. |
