Filed:

Nov 22, 2002

Appl. No.:

10/301703

Inventors:

Raymond Allan Wedlake - Greenville SC
David Alan Meier - Simpsonville SC
Devin Martin - Piedmont SC
Marvin Neeley - Mauldin SC

Assignee:

General Electric Company - Schenectady NY

International Classification:

F01D 514

US Classification:

416223A, 416DIG 2

Abstract:

Third stage turbine buckets have airfoil profiles substantially in accordance with Cartesian coordinate values of X, Y and Z set forth Table I wherein X and Y values are in inches and the Z values are non-dimensional values from 0 to 1 convertible to Z distances in inches by multiplying the Z values by the height of the airfoil in inches. The X, Y and Z 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 bucket. The nominal airfoil given by the X, Y and Z distances lies within an envelop of Â0. 160 inches in directions normal to the surface of the airfoil.

General Electric Company - Schenectady NY

International Classification:

F01D 9/04

US Classification:

415191, 415193, 4152101

Abstract:

A turbine nozzle includes airfoil and sidewall surfaces. The airfoil and sidewall surfaces have profiles substantially in accordance with Cartesian coordinate values of X, Y and Z set forth in Tables I–IV for the pressure and suction sides of the airfoil, and the outer and inner sidewall surfaces, respectively. The X, Y and Z values are distances in inches. The X and Y values for the airfoil, when connected by smooth continuing arcs, define airfoil profile sections at each distance Z. The profile sections at the Z distances are joined smoothly with one another to form a complete airfoil shape. The X, Y and Z values of Tables III and IV define the outer and inner sidewall surfaces, respectively, of the gas flowpath.

International Classification:

F01D 514

US Classification:

416223R, 416DIG 2, 415192

Abstract:

The third-stage nozzles have vanes comprising airfoil profiles substantially in accordance with Cartesian coordinate values of X, Y and Z set forth in inches in Table I wherein Z is a perpendicular distance from a plane normal to a radius of the turbine centerline and containing the X and Y values with the Z value commencing at zero in the X, Y plane at the radially innermost aerodynamic section of the airfoil and X and Y are coordinate values defining the airfoil profile at each distance Z. The X, Y and Z values may be scaled as a function of the same constant or number to provide a scaled-up or scaled-down airfoil section for each nozzle vane.
