    Abstract: A coolable airfoil (10) having a plurality of spanwisely extending passages is disclosed. Various construction details are developed to increase the cooling effectiveness of the internal structure and decrease the need for cooling air. In one particular embodiment, a leading edge passage (56) has film cooling air flowing over the passage to shelter the passage from the hot working medium gases. This sheltered cooling air is then mixed with heated cooling air from a tortuous passage (84, 92) flowing through the mid-chord region (68) of the blade. In one embodiment, the coating air is supplied to a chordwisely extending tip passage (74) to cool the airfoil tip region and is mixed in the passage (74).
