In a gas turbine engine the turbine blade has protective flanges closely overlying the rim of the rotor to shield the rotor from the hot power gases and to form a path for cooling air. These flanges are spaced radially inward from the flanges on the blade that define the inner wall of the gas path through the turbine.

A turbine blade having an airfoil section, a platform at the inner end of the airfoil section, a shank extending from the platform from the side opposite to the airfoil section, opposed flanges extending outwardly in substantially parallel relation to the platform at the end of the shank, and a blade root immediately at the end of the shank on the other side of the flanges, said opposed flanges being of such a dimension that when the blade is assembled on the disk, the flanges of adjacent blades will be closely adjacent to one another and closely overlying and in spaced relation to the rim of the disk to form an axial air passage at said rim.
