    摘要: First stage stator vanes for a turbine comprised airfoil profile substantially in accordance with Cartesian coordinate values of X, Y and Z set forth in inches in Table I, which define a plurality of radially spaced profile sections forming the nominal profile. The Z coordinate values for each profile section are radial distances from the turbine axis to a portion of the surface of revolution about the axis containing the profile section. The X and Y values for each profile section are coordinate values which, when connected by smooth continuing arcs define the airfoil profile section along the surface of revolution portion. The radially spaced profile sections are joined smoothly with one another to form the nominal airfoil profile.

    摘要: Nozzle segments are secured to a retention ring against circumferential rotation by anti-rotation pins extending generally axially between the outer bands of the nozzle segments and the retention ring. Retention plate segments overlie the ends of the pins, preventing axial removal thereof. To remove a selected nozzle segment, inner diameter retention plate segments and selected retention plate segments are removed, the latter exposing the ends of the pins for axial withdrawal. Upon removal of a predetermined number of pins, the nozzle segments adjacent the selected segment are displaced away from the latter segment to open a gap between the selected segment and adjacent segments whereby the selected segment can be removed in an axial direction.

    摘要: A turbine nozzle includes, in an exemplary embodiment, an outer band portion, an inner band portion at least one nozzle vane extending between the inner band portion and the outer band portion, and at least one cooling channel extending axially at least partially through at least one of the outer band portion and the inner band portion. The at least one nozzle vane, the inner band portion, and the outer band portion define a flowpath for flowing hot gases of combustion. Each cooling channel includes at least one inlet with each inlet isolated from the flowing hot gases of combustion.

    摘要: A system and method for analyzing a baseline geometry and, optionally, a modified geometry. The method can include generating a numerical representation of a baseline geometry having baseline elements identified with first identifiers or element identifiers, and then assigning second identifiers or analyzer identifiers to the elements. Thermal characteristics of the geometry are analyzed with reference to the second or analyzer identifiers. The results of the thermal analysis can be provided as an input for a structural analysis of the baseline geometry. At least one of the elements of the geometry can then be altered in a manner that at least partially automatically adjusts the surrounding geometry, and the same first identifier or element identifier is associated with the altered element as was associated with the baseline, unaltered element. The altered geometry can be analyzed with respect to a third identifier (or another analyzer identifier) and a correspondence between the identifiers, the baseline element, and the altered element can be established and maintained. Accordingly, the boundary conditions and/or the mesh applied to the baseline geometry can be automatically applied to the altered geometry by referring to the first or element identifiers. Therefore, the time and effort required to analyze the altered geometry can be reduced when compared to the effort typically required by conventional methods.

    摘要: The first stage nozzles have airfoil profiles substantially in accordance with Cartesian coordinate values of X, Y and Z set forth Table I. The X and Y values are in inches and the Z value is in inches along the nozzle stacking axis coincident with a turbine radius. The X and Y distances may be scalable as a function of the same constant or number to provide a scaled up or scaled down airfoil section for the nozzle. The nominal airfoil given by the X, Y and Z distances lies within an envelope of ±0.160 inches.
