Turbine nozzle

A segment of a turbomachine nozzle is tangentially held in position by a pair of lugs extending radially from the outer and inner bands, respectively, at opposite ends of the segment, and resting against the adjacent support structure. In this way, the stress in the vanes and bands is maintained at...

Zusammenfassung:	A segment of a turbomachine nozzle is tangentially held in position by a pair of lugs extending radially from the outer and inner bands, respectively, at opposite ends of the segment, and resting against the adjacent support structure. In this way, the stress in the vanes and bands is maintained at a low level to thereby allow the use of high temperature, relatively low strength materials and reduced cooling measures. The lugs form integral end caps on the vane's one end and the cooling air enters the opposite end thereof.
