Abstract:
A rotor blade ( 16 ) for a turbine of a gas turbine that includes an airfoil ( 25 ). The airfoil may have a leading edge, a trailing edge, an outboard tip, and an inboard end where the airfoil attaches to a root configured to couple the turbine blade to a rotor disc. The airfoil ( 25 ) may include a tip shroud ( 55 ) at an outboard tip. The rotor blade may have a cooling configuration that includes: elongated cooling channels ( 33 ) for receiving and directing a coolant through the airfoil ( 25 ); and branching passages ( 75 ) formed through the tip shroud ( 55 ), each of which elongates between a connection with one of the cooling channels ( 33 ) and an outlet port ( 37 ) formed on a surface of the tip shroud ( 55 ). The branching passages ( 75 ) may have a canted orientation relative the outboard surface of the tip shroud ( 55 ).

Claim (Index 10):
The turbine rotor blade according to  claim 5 , wherein a rotation direction comprises a direction of rotation for the rotor blade during expected operation in the turbine;\n wherein a second discharge angle is defined between the discharge direction and a reference line parallel to the rotation direction; wherein the tip shroud comprises a seal rail that projects radially outward from the outboard surface of the tip shroud and extends circumferentially in the rotation direction; wherein the outboard surface of the tip shroud comprises a leading portion that extends forward from the seal rail so to overhang the leading edge of the airfoil, and a trailing portion that extends afterward from the seal rail so to overhang the trailing edge of the airfoil; wherein the outlet ports of multiple ones of the branching passages comprise a position on the leading portion of the outboard surface; and wherein the second discharge angle of the multiple ones of the branching passages having the outlet ports on the leading portion of the outboard surface comprises an angle less than about 45\u00b0 relative to the reference line pointing with the rotation direction.
