Abstract
A compressor stator includes an axial centerline axis and has a unitary annular outer case and a plurality of circumferentially spaced outer hooks extending radially inwardly therefrom. A circumferentially segmented inner case is disposed radially inwardly within the outer case and includes a plurality of arcuate inner case segments, each including an arcuate shroud and at least one inner hook extending radially outwardly therefrom, with respective ones of the outer and inner hooks being axially slidably joined to each other for radially supporting an inner surface of the shroud at a common radius.
Claims15
A compressor stator having an axial centerline axis comprising:
- a unitary annular outer case disposed coaxially with said centerline axis and having a plurality of circumferentially spaced outer hooks extending radially inwardly therefrom and axially parallel to said centerline axis;
- a circumferentially segmented inner case disposed radially inwardly of said outer case and coaxially with said centerline axis, and having a plurality of circumferentially abutting, arcuate inner case segments, each of said inner case segments including an arcuate shroud having outer and inner surfaces, and at least one inner hook extending radially outwardly from said shroud outer surface and axially parallel to said centerline axis;
- and
- said outer and inner hooks being complementary in shape, with respective ones of said outer and inner hooks being axially slidably joined to each other for radially supporting said shroud inner surfaces at a common radius.
