Abstract
A turbine nozzle includes: a hollow, airfoil-shaped turbine vane; and an arcuate first band disposed at a first end of the turbine vane, the first band having a flowpath face adjacent the turbine vane, and an opposed back face. The back face includes at least one open pocket, the at least one pocket defined in part by a bottom wall recessed from the back face, opposed ends of the bottom wall merging with the back face. The bottom wall is substantially free of interior corners.

A turbine nozzle comprising:
- (a) a hollow, airfoil-shaped turbine vane;
- (b) an arcuate first band disposed at a first end of the turbine vane, the first band having a flowpath face adjacent the turbine vane, and an opposed back face;
- (c) wherein the back face includes at least one open pocket, the at least one pocket defined in part by a bottom wall recessed from the back face, opposed ends of the bottom wall merging with the back face;
- and
- (d) wherein the bottom wall is substantially free of interior corners.
A turbine assembly for a gas turbine engine, comprising:
- (a) a turbine rotor comprising a disk carrying a plurality of airfoil-shaped turbine blades extending across a primary flowpath;
- and
- (b) a turbine nozzle disposed upstream of the rotor, comprising:
- (i) a plurality of hollow, airfoil-shaped turbine vanes extending across the primary flowpath;
- (ii) an arcuate inner band disposed at an inner end of the turbine vane, the inner band having a flowpath face facing radially outward, and an opposed back face;
- (iii) wherein the back face includes at least one open pocket, the at least one pocket defined in part by a bottom wall recessed from the back face, opposed ends of the bottom wall merging with the back face;
- and
- (iv) wherein the bottom wall is substantially free of interior corners.
