Abstract
A turbine nozzle includes inner and outer bands having respective air inlets. A plurality of hollow vanes are integrally joined to the bands in flow communication with the inlets. Each vane includes first and second cooling channels extending between the bands which are separated by an inclined septum which converges the two channels away from the corresponding inlets for reducing pressure drop as the cooling air is discharged.
Claims25
A turbine nozzle comprising:
- an inner band having a first inlet for receiving cooling air;
- an outer band having a second inlet for receiving cooling air;
- a plurality of vanes extending integrally between said bands, and each vane having opposite pressure and suction sides extending between leading and trailing edges and between said bands;
- a first cooling channel extending through each of said vanes between said bands in flow communication with said first inlet;
- a second cooling channel extending through each of said vanes between said bands in flow communication with said second inlet;
- and
- a septum integrally formed in each of said vanes between said inner and outer bands to separate said first and second channels, and being inclined between said bands for converging said first channel away from said first inlet, and converging said second channel away from said second inlet.

A turbine nozzle comprising:
- inner and outer bands having respective first and second air inlets;
- a plurality of hollow vanes joined integrally to said bands in flow communication with said air inlets;
- and
- first, second, and third cooling channels extending through each of said vanes, and separated in turn by a septum and a bridge integrally formed between said inner and outer bands, and said septum being inclined therebetween for separately converging said first and second channels oppositely to each other, with said first channel converging away from said first inlet, and said second channel converging away from said second inlet.
