    摘要: Hybrid turbine airfoil components (30,100) containing a ceramic material, in which detailed features of the components (30,100) are formed of materials other than ceramic materials. The components (30,100) include a first component (44,102) formed of a ceramic-based material and a second component (46,104) formed of a metallic material. The first component (44,102) comprises an airfoil portion (38,102) and a nub (48,106), and the second component (46,104) is separately formed and attached to the first component (44,102) by casting the metallic material around the nub (48,106) of the first component (44,102). The second component (46,104) includes a platform portion (36,104) between the airfoil portion (38,102) and the nub (48,106) of the first component (44,102) and a dovetail portion (32,106) on the nub (48,106) of the first component (44,102). Each of the platform and dovetail portions (36,104;32,106) has at least one off-axis geometric feature (34,36,42,104) that results in the second component (46,104) having a more complex geometry than the first component (44,102).

    摘要: A ceramic shroud assembly (99) includes a tip shroud (88) having an outer platform (86) supporting at least one seal tooth (91), a shroud cap (96) less brittle than the outer platform (86) and including a shroud cap base (98) on the outer platform (86), and clockwise and counter-clockwise facing clockwise and counter-clockwise contact surfaces (152, 153) located at clockwise and counter-clockwise distal ends (124, 126) respectively of the base. A rotor (34) assembly may include a circumferential row (38) of turbine blades (70) made of a ceramic material and extending radially outwardly from a disk (73) of a turbine rotor (34). The turbine blades (70) include airfoils (72) having the airfoil tip shrouds (88) and the shroud caps (96) at blade tips (77). The clockwise and counter-clockwise contact surfaces (152, 153) of circumferentially adjacent ones (71) of the shroud caps (96) contact each other. The shroud (88) and the platform (86) may be made of a ceramic or ceramic matrix composite material and the shroud cap (96) may be made of a metallic material.

    摘要: A turbine blade and a method of fabricating the same. The method for fabricating a turbine blade includes casting at least one turbine blade that includes a blade tip shroud (112) and at least one seal tooth (114) coupled to the blade tip shroud, and removing at least a portion (116) of the turbine blade such that a radially outer surface (118) of the blade tip shroud has at least two substantially flat surfaces. Preferably, the blade tip shroud (112) has a substantially V-shaped cross-sectional profile (120).

    摘要: A method enables a gas turbine engine blade (42) to be manufactured to include an airfoil, a platform (52), a shank (54), and a dovetail (56). The platform extends between the airfoil and the shank, the shank extends between the dovetail and the platform, and the dovetail includes at least one tang (84,86) for securing the blade within the engine. The method comprises defining a cooling cavity (102) in the blade that extends through the airfoil, the platform, the shank, and the dovetail, such that a portion of the cavity defined within the dovetail includes a root passage portion having a first width (D R ), and a transition portion (122) extending between the root passage and the portion (114) of the cavity defined within the shank, and wherein the portion of the cavity defined within the shank has a second width (D S ) that is larger than the root passage first width + portion of the inner surface of the cooling cavity (102) is coated with a layer of an oxidation resistant environmental coating.
