    摘要： An airfoil includes an airfoil working portion and an adjoining endwall. The endwall has a leading edge, a trailing edge, a first mateface, and a second mateface that collectively define a perimeter of the endwall, with the first and second matefaces arranged opposite one another. A forward zone is defined by the endwall that extends to the leading edge. The first and second matefaces are each oriented at an angle alphaII relative to radial in the forward zone. An aft zone is defined by the endwall that extends to the trailing edge. The first and second matefaces are each oriented at an angle alphaII relative to radial in the aft zone. The angles alphaII and alphaII are not equal. A middle zone is defined in between the forward and aft zones, and the first and second matefaces transition between the angles alphaII and alphaI in the middle zone.

    摘要： A vane assembly includes first and second annular metal rings (31,48) configured to accept a compressed gas flow therebetween. The first and second annular rings each include a cutout portion (38). The assembly further includes a ceramic matrix composite vane (30) configured as an airfoil having a blunt rounded nose and a flattened and tapered tail. A first radial end of the vane is rigidly disposed on the first annular ring and a second radial end of the vane is slidably disposed within the cutout portion of the second annular ring such that the vane is encompassed by the first and second annular rings. The vane includes a hollow through opening portion extending radially therethrough. Still further, the assembly includes a metallic elongated member (33) disposed within and extending through the hollow portion of vane and through the cutout portion of the first annular ring.
