<p>The stage has a vane disk surrounded with a sectorised ring supported by a casing and comprising a circumferential flange radially clamped on an annular rail of the casing by C-shaped cross-section locks (40) that are axially engaged on a casing rail and a flange of the ring. Each lock includes circumferentially directed parallel outer and inner walls (42, 44) that are connected together by a radial wall (46). The walls comprise a radial supporting or bearing unit on the flange and the casing rail, where the bearing unit only extends on a part of a width or angular extent of the lock.</p> |
