摘要： A rotor blade (14) is provided having a hollow airfoil (22) and a root (20). The hollow airfoil (22) has a cavity defined by a suction side wall (38), 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 includes a first radial passage (48), a second radial passage (50), and a rib (53) disposed between and separating the first radial passage (48) and second radial passage (50). A plurality of crossover apertures (52) are disposed within the rib (53). A portion of the plurality of crossover apertures (52) are oblong having a length (70) extending through the rib (53), and a height (74) and a width (72). The height (74) of each oblong aperture (52) is greater than the width (72). In some embodiments, the oblong crossover apertures (52) are aligned heightwise along the rib (53). The root (20) includes a conduit (42) that is operable to permit airflow through the root (20) and into the first radial passage (48).

摘要： A turbine blade cooling system for a gas turbine engine includes a turbine blade (100) having a trailing edge, a concave side (104), and a convex side (102). The trailing edge defines at least one set of impingement holes (106, 112) each having a central longitudinal axis which is closer to a nearest portion of an edge of the blade at one of the concave (104) and convex (102) sides relative to a nearest portion of an edge of the blade at the other of the concave (104) and convex (102) sides. Alternatively or in addition to the foregoing, the trailing edge can define at least one set of impingement holes (206, 212) each having a central longitudinal axis which is angled in a direction of a flow of cooling medium toward one of the concave (204) and convex (202) sides relative to the other of the concave (204) and convex (202) sides.

摘要： A turbine blade system for a gas turbine engine includes a turbine blade 100,200 having a trailing edge region extending in a lateral direction and in a lengthwise direction from a pressure side surface 110;210 to a trailing edge 112;212. The trailing edge region includes a plurality of riblets 104;204 extending in the lengthwise direction from the pressure side surface 110;210 toward the trailing edge 112;212. The trailing edge region defines a plurality of ejection slots 106;206 each laterally disposed between two of the riblets 104;204. The plurality of riblets 104;204 each define an upper surface 108;208 having at least a portion in the lengthwise direction being curved relative to the pressure side surface 110;210 so as to generally shield the upper surface 108;208 from a high heat load propagating from the pressure side surface 110;210 and to facilitate cooling air flowing from the ejection slots 106;206 to flow over the upper surface 108;208.
