초록 ▼

A turbine nozzle support assembly includes nozzle segments each having an inner band with an integral retention flange extending radially inwardly therefrom. A plurality of retention tabs extend radially inwardly and are spaced axially aft of the retention flange to define a capture slot therebetween. A nozzle support includes a radially outwardly extending upper flange having a plurality of support pins extending axially, forwardly therefrom and disposed in complementary retention apertures in the retention flanges of the nozzle segments. A retention key is disposed in the capture slot axially between the upper flange and the retention tabs for axially retaining the nozzle segments on the nozzle support.

A turbine nozzle support assembly comprising: a plurality of circumferentially adjoining nozzle segments each nozzle segment including a vane fixedly joined to radially outer and inner arcuate bands, said vane having an axially forward, upstream edge and an axially aft, downstream edge over which combustion gases are flowable, said inner band having an integral retention flange extending radially inwardly from an axially intermediate portion of said inner band, and a plurality of integral, circumferentially spaced apart retention tabs extending radially inwardly and spaced axially aft from said retention flange to define a capture slot therebetween; an annular nozzle support supporting said plurality of nozzle segments, said nozzle support having at a distal end thereof a radially outwardly extending upper flange disposed axially between said retention flanges and said retention tabs and including a plurality of circumferentially spaced apart support pine facing axially forwardly and disposed in complementary retention apertures in said retention flanges for radially and circumferentially retaining said nozzle segments on said nozzle support; each of said pins having axially forward and aft, opposite ends, with said pin aft ends being fixedly joined to said upper flange and spaced axially forwardly from said retention tabs; said capture slot being sized to allow each of said nozzle segments to be installed radially inwardly over said upper flange and said pins without obstruction therefrom, and without obstruction of said retention tabs with said upper flange until said retention aperture is aligned with a respective one of said pins; and a beltless retention key disposed in said capture slot axially between said upper flange and said retention tabs, and having a diameter to position said entire retention key radially in line with said retention tabs, for axially retaining said nozzle segments on said nozzle support to prevent axially forward movement of said retention flange off said pin.
