Abstract
A turbine nozzle assembly includes an outer casing having first and second spaced apart support flanges for supporting a nozzle segment including a plurality of nozzle vanes extending between inner and outer bands. The outer band includes first and second spaced apart retention hooks, with the first hook being configured to axially engage the first support flange. And, the second support flange is sized for axially receiving the second hook without tilting of the nozzle segment. An annular retainer radially engages the second support flange and axially abuts the second hook for axially retaining the second hook. And, a clip axially engages the second hook and support flange around the retainer for radially supporting the nozzle segment to the outer casing.
Claims7
A gas turbine engine nozzle assembly comprising:
- an outer casing having first and second radially inwardly extending and axially spaced apart annular support flanges;
- a nozzle segment including a plurality of circumferentially spaced apart nozzle vanes extending radially between inner and outer bands, said outer band including first and second axially spaced apart retention hooks;
- with said first hook being configured to axially engage said first support flange for radially supporting said nozzle segment, and said second support flange including means for axially receiving said second hook without tilting of said nozzle segment;
- an annular retainer radially engaging said second support flange and axially abutting said second hook for axially retaining said second hook;
- and
- an annular C-sectioned clip axially engaging said second hook and support flange around said retainer for radially supporting said nozzle segment.

- a nozzle segment including a plurality of circumferentially spaced apart nozzle vanes extending radially between inner and outer bands, said outer band including first and second axially spaced apart retention hooks;
- with said first hook being configured to axially engage said first support flange for radially supporting said nozzle segment, and said second support flange being sized greater in diameter than said second hook for axially receiving said second hook along said support flange without tilting of said nozzle segment;
- an annular retainer radially engaging said second support flange and axially abutting said second hook for axially retaining said second hook;
- and
- an annular C-sectioned clip axially engaging said second hook and support flange around said retainer for radially supporting said nozzle segment.

- and wherein
- said second hook comprises a radial leg extending outwardly from said outer band, and an integral axial leg spaced above said outer band to define an axial inner slot therebetween;
- and
- said second support flange comprises a flat axial seat for receiving said axial leg;
- a radial slot adjoining said seat for receiving said retainer and abutting said axial leg;
- and an axial outer slot disposed above said radial slot and retainer;
- and
- said clip axially engages said inner and outer slots.
