ABSTRACT:
A turbine airfoil usable in a turbine engine and having at least one cooling system. The turbine airfoil may include an interlayer coupled to an outer surface of the outer wall of the airfoil, wherein the interlayer may be formed from a porous material that allows cooling fluids to pass through the interlayer. The floating wall may be coupled to an outer surface of the interlayer, wherein the floating wall may be formed from a plurality of floating wall segments positioned in close proximity to each other but with a film cooling slot positioned between the adjacent wall segments to enable cooling fluids to be exhausted from the elongated hollow airfoil. The cooling system may include an outer wall diffusion chamber positioned in the outer wall and an interlayer diffusion chamber. One or more metering holes may be in communication with the outer wall and interlayer diffusion chambers.
