Abstract
A rotor blade () for a turbine of a gas turbine that includes an airfoil (). 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 () may include a tip shroud () at an outboard tip. The rotor blade may have a cooling configuration that includes: elongated cooling channels () for receiving and directing a coolant through the airfoil (); and branching passages () formed through the tip shroud (), each of which elongates between a connection with one of the cooling channels () and an outlet port () formed on a surface of the tip shroud (). The branching passages () may have a canted orientation relative the outboard surface of the tip shroud ().
