Appl. No.:

16/191614

Assignee:

General Electric Company - Schenectady NY

International Classification:

F01D 9/04
F01D 5/14

Abstract:

A turbine nozzle having an airfoil that includes a pressure side portion of a nominal airfoil profile substantially in accordance with Cartesian coordinate values of X, Y, and Z of a pressure side as set forth in Table I. The Cartesian coordinate values of X, Y, and Z are non-dimensional values from 0% to 100% convertible to dimensional distances by multiplying the Cartesian coordinate values of X, Y and Z by a height of the airfoil defined along the Z axis. The X and Y values of the pressure side are coordinate values that, when connected by smooth continuing arcs, define pressure side sections of the pressure side portion of the nominal airfoil profile at each Z coordinate value. The pressure side sections may be joined smoothly with one another to form the pressure side portion.

Abstract:

A stationary component of a turbine section of a turbine engine system includes a hollow vane assembly with an interior rib separating a first interior compartment from a second interior compartment. The first and second interior compartments are configured to receive the cooling fluid. The cooling fluid is allowed to communicate between the first and second interior compartments. The stationary component also includes a diaphragm attached to the hollow vane assembly. The diaphragm is configured to receive the cooling fluid from the hollow vane assembly. The diaphragm includes a chamber and a tube extending through the chamber. The tube is configured to isolate the chamber from the cooling fluid while delivering the cooling fluid from the hollow vane assembly to the wheelspace area.
