Abstract:
A coolable airfoil for exposure in a hot fluid flow of a machine portion, comprising:said airfoil being configured to be connectable with said machine portion, said airfoil including a peripheral portion surrounding a medial portion, and a chordwise extending pressure side joined with a chordwise extending suction side, wherein said medial portion extends circumferentially from said peripheral portion adjacent said pressure side to said peripheral portion adjacent said suction side;at least a first channel disposed in said peripheral portion of said pressure side and at least a second channel disposed in said peripheral portion of said suction side; anda flow path formed from said machine portion and through said first and second channels in which said flow path is configured to direct a coolant fluid substantially radially outward through said first channel in said peripheral portion of said pressure side and substantially radially inward through said second channel in said peripheral portion of said suction side to cool said airfoil.
