<p>A rotor blade (14) and includes a root (20) and a hollow airfoil (22) having a cavity defined by suction side wall (78), a pressure side wall (36), a leading edge (32), a trailing edge (34), a base (28), and a tip (30). An internal passage configuration (40) is disposed within the cavity. The configuration (40) includes a serpentine passage (78) having at least three radial segments (80) connected to one another, an axially extending passage (52) disposed between the tip (30) and the serpentine passage (78), at least one aperture (85) extending between the last radial segment (80) and the axially extending passage (52), and one or more sink apertures (84) disposed within one of the suction side wall (38) or the pressure side wall (36) of the last radial segment (80) of the serpentine passage (78). At least one conduit (42;44;46) is disposed within the root (22). The conduit (42;44;46) is operable to permit airflow through the root (20) and into the internal passage configuration (40). <IMAGE></p> |
