ABSTRACT:
A turbine blade for use in an industrial gas turbine engine, the blade having a squealer pocket with a plurality of discrete curved cooling channels to cool the blade tip and to reduce the hot gas flow leakage across the tip. The curved cooling channels include a side wall cooling channel, a tip rail crown cooling channel and an inner tip rail wall cooling channel all discharging cooling air from a cooling supply channel within the airfoil. Both the pressure side and suction side tip rails include this arrangement of cooling channels.
