Patent ID: 8408866

Claim:
A turbine airfoil arrangement, comprising: an airfoil having an inlet and an exit, said inlet configured to receive a cooling gas flow operable to cool at least part of an other airfoil; and a passage disposed in said airfoil and fluidly coupled to said inlet and said exit, said exit being configured to pass a portion of the cooling gas flow to the other airfoil, further comprising: a second airfoil, wherein said second airfoil is the other airfoil; and a second passage disposed in said second airfoil and fluidly coupled to said exit, said second passage being configured to receive the portion of the cooling gas flow and to cool said at least part of said second airfoil using the portion of the cooling gas flow, further comprising: a first seal; a second seal; and a cavity disposed between said first seal and said second seal, said cavity fluidly coupling said exit and said second passage.
