ABSTRACT:
Turbine nozzle vane cooling difficulties may be avoided in a gas turbine including a rotary compressor (10), (14) having a turbine wheel (10), (16) connected to the same; a nozzle (34) having a plurality of vanes (36) surrounding the turbine wheel (10), (16) for directing products of combustion thereat; and a combustor (28) for burning fuel and providing the products of combustion to the nozzle (34). The vanes (36) have elongated openings (54) in the leading edges (42) thereof, the openings terminating in generally parallel, curved surfaces (62), (64) that merge with the leading edges (42). The openings (54) are in fluid communication with the compressor (10), (14) and, as a consequence, compressed air flowing out of the openings (54) attaches itself to the surfaces (66), (68) of the leading edge (42) of the vanes (36) to provide exit cooling.
