TURBINE ROTOR BLADE AND GAS TURBINE ENGINE

A turbine rotor blade includes a tip portion (46) having a pressure tip wall (62) and a suction tip wall (64), a tip leading edge (68) and a tip trailing edge (70), wherein the pressure tip wall and the suction tip wall define a trailing edge tip thickness. Also included is a squealer cavity (80) at...

More Information
Summary:A turbine rotor blade includes a tip portion (46) having a pressure tip wall (62) and a suction tip wall (64), a tip leading edge (68) and a tip trailing edge (70), wherein the pressure tip wall and the suction tip wall define a trailing edge tip thickness. Also included is a squealer cavity (80) at least partially defined by the pressure tip wall and the suction tip wall, the squealer cavity including a trench (84) extending fully to the tip trailing edge to form an open flow path out of the tip trailing edge. Further included is a suction side wall (50) and a pressure side wall (48) extending from a root portion (44) of the turbine rotor blade to the tip portion, wherein the suction side wall and the pressure side wall define a trailing edge blade thickness, the trailing edge tip thickness being greater than the trailing edge blade thickness.
