Abstract: A near flow path seal member includes a seal body having a first end portion extending to a second end portion having a dovetail member. The first end portion includes a third end and a fourth end having a surface extending therebetween and facing away from the dovetail member, the surface having a longitudinal axis extending between the third end and the fourth end. A recess formed in the surface has a geometry to receive a seal element assembly having a base extending to at least one seal element. The seal element assembly is selectively installable or removable from the recess.

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).
