摘要： A turbine includes a turbine wheel having a plurality of buckets, each of the buckets including a bucket airfoil, a bucket dovetail to connect the bucket to a turbine wheel and a shank shape to connect the airfoil to the bucket dovetail, the shank having an uncoated nominal profile including a concave, pressure side, substantially in accordance with Cartesian values of X, Y and Z′ set forth in Table I wherein the Z′ values are non-dimensional values in a range from 0 to 1 convertible to Z distances in inches by multiplying the Z′ values by shank height in inches, and a convex, suction side, substantially in accordance with Cartesian values of X, Y and Z′ set forth in Table II wherein the Z′ values are non-dimensional values in a range from 0 to 1 convertible to Z distances in inches by multiplying the Z′ values by the shank height in inches. The X and Y are distances in inches which, when connected by smooth continuing arcs, define a shank profile section at each distance Z, the profile sections being joined smoothly with one another to form a complete shank shape.

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.
摘要翻译：喷嘴段通过在喷嘴段的外带和保持环之间大致轴向延伸的防旋转销固定到保持环以防止圆周旋转。保持板段覆盖销的端部，防止其轴向移除。为了去除所选择的喷嘴段，去除内径保持板段和选定的保持板段，后者将引脚的端部暴露以用于轴向退出。在移除预定数量的销之后，与所选择的段相邻的喷嘴段从后段移开，以打开选定段和相邻段之间的间隙，从而可以沿轴向移除所选段。

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.
