Abstract: A rotor blade (14) is provided having a hollow airfoil (72) and a root (20). The hollow airfoil (22) has a cavity (40) and one or more cooling apertures (32,76,90). The root (20) is attached to the airfoil (22), and has a leading edge conduit (42), at least one mid-body conduit (44), and a trailing edge conduit (46). The conduits are operable to permit airflow through the root and into the cavity. Each conduit (42,44,46) has a centerline (58,74,88). The leading edge conduit (42) includes an inlet (48) having a forward side (50), a suction side (52), and a pressure side (56) that diverge from the centerline (58) of the leading edge conduit (42), and an aft side (52). Each of the mid-body conduits (44) includes an inlet (64) having a suction side (66) and a pressure side (68) that diverge from the centerline (74) of the mid-body conduit (44), and an aft side (70) and a forward side (72). The trailing edge conduit (46) includes an inlet (78) having a suction side (84) and a pressure side (86) that diverge from the centerline (88) of the trailing edge conduit (46). The trailing edge conduit inlet (78) further includes a forward side (82) and an aft side (80).
