Abstract

A rotor blade (26) for a gas turbine engine (10) includes an airfoil (34) and a cooling microcircuit (36, 38, 40). The airfoil (34) includes a first side wall (42), a second side wall (44) and a tip endwall (50), where the first side wall (42) and the second side wall (44) extend to and cooperate to form the tip endwall (50), defining a main cavity (62) between the first side wall (42) and the second side wall (44). The cooling microcircuit (36, 38, 40) includes a microcircuit cavity (72), an inlet (74), a side wall outlet (76) and a tip outlet (78). The microcircuit cavity (72) is embedded within the first side wall (72), and the inlet (74) extends from the main cavity (62) to the microcircuit cavity (72). The side wall outlet (76) extends from the microcircuit cavity (72) to an exterior first side surface of the airfoil (42). The tip outlet (78) extends from the microcircuit cavity (72) to an exterior tip surface (52, 54) of the airfoil.
