ABSTRACT:
The invention comprises sealing structure between a seal plate, a rotor, and a blade, for sealing the root portion of a rotor and blade assembly to provide a sealed chamber adjacent the base of the root into which radially directed passageways in the blade open for transmitting the cooling fluid, delivered to the chamber, through the blade to the tip end thereof to cool the blade. The seal is perfected through a wedging action caused by centrifugal force moving the base or foot of the plate, disposed below the blade root, into sealing engagement with the rotor disk, and an intermediately disposed seal bar extending arcuately just radially outwardly of the radially innermost portion of the root and generally in the vicinity of the innermost loaded root projection with the loaded root providing the axial seal and the sealing bar and seal plate foot providing the radial seals to define a cooling fluid chamber adjacent the base of the root.
