    摘要： A turbine nozzle (18) includes segments (18a) of outer and inner bands (30,32) supporting corresponding vane pairs (28). The bands adjoin each other at corresponding ends (42,44) along splitlines (46), with each band having a forward land (42a, 44a), an opposite aft land (42b, 44b), and a middle land (42c, 44c) extending therebetween. The forward lands have a nominal aft-facing step (48), the aft lands have a nominal forward-facing step (50) and the middle lands are nominally flush.

    摘要： A nozzle vane (18) includes a row of trailing edge apertures (34) and cooperating inboard slots (36) joined in flow communication with a mid-chord cavity (38). An outboard slot (46) is spaced outwardly from a respective last one of the inboard slots, and outboard of a respective last one of the trailing edge apertures. The outboard slot extends behind a braze joint (24) between the vane and a supporting band and is effective for backside cooling thereof.

    摘要： A dovetail assembly (61) including non-parallel relief faces (82) that facilitates reduced pressure face brinelling in turbine engines. The assembly includes a plurality of rotor blades, each including a dovetail (44). Each dovetail includes at least a pair of blade tangs (66, 68, 70, 72) including blade relief faces (82, 84). The dovetail assembly also includes a rotor disk (26) including a plurality of dovetail slots (60), each sized to receive a dovetail. Each dovetail slot is defined by at least one pair of opposing disk tangs (120, 122, 124, 126) including disk relief faces (148, 150). The disk relief faces are non-parallel to the blade relief faces when the dovetail is mounted in the dovetail slot.
