Abstract
A turbine nozzle includes outer and inner bands having respective mounting holes therein. A plurality of vanes extends through respective pairs of outer and inner holes in the bands. The vane outer and inner ends are resiliently supported to the bands to allow differential thermal movement therebetween so that the individual vanes float relative to the outer and inner bands to prevent thermal stress failure thereof.
Claims19
A turbine nozzle comprising:
- an outer band including a plurality of circumferentially spaced apart outer mounting holes;
- an inner band spaced from said outer band and including a plurality of circumferentially spaced apart inner mounting holes;
- a plurality of vanes extending through respective pairs of said outer and inner holes, and each vane having outer and inner ends disposed correspondingly thereat, and being shaped for channeling combustion gas thereover;
- and
- means for resiliently supporting said vanes to said outer and inner bands for allowing differential thermal movement between said vanes and said outer and inner bands.
