Abstract
A turbine nozzle includes a row of vanes in corresponding segmented outer and inner bands. The inner band of each segment includes a retention flange. A nozzle support includes forward and aft flanges defining a retention slot receiving the retention flange. The retention flange includes a radial lug trapped axially in the retention slot, and a tangential lug at an opposite circumferential end disposed on the forward flange. The aft flange includes an outer hinge, and the retention flange further includes an inner hinge for cradle mounting the retention flange in the nozzle support.
Claims20
A turbine nozzle comprising:
- a row of nozzle segments each including a plurality of vanes extending radially between outer and inner bands, and each of said inner bands includes a radially inwardly extending retention flange, and each of said outer bands includes an outer pad facing aft at an aft end thereof for carrying axial loads to an annular supporting casing;
- an annular nozzle support disposed radially inwardly of said nozzle segments and including radially outwardly extending forward and aft flanges spaced apart axially to define an annular retention slot;
- said retention flange including a single radial lug at a first circumferential end trapped axially in said retention slot, and a tangential lug at an opposite second circumferential end disposed on said forward flange for carrying radial loads thereto;
- and
- said aft flange including a chordally straight outer step defining an outer hinge, and said retention flange further including a chordally straight inner step disposed inwardly of said outer hinge defining an inner hinge for cradle mounting said retention flange in said nozzle support.
