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.
