A turbine or compressor stage for a turbomachine is disclosed. The stage includes a blade wheel surrounded by a sectorized ring carried by a casing. Each ring sector includes a circumferential rim that is clamped radially a casing rail by two clamps of C-shaped section that are engaged on the circumferential end portions of the rim of the ring sector and on the corresponding portions of the casing rail.

Turbine or compressor stage for a turbomachine

A turbojet turbine or compressor stage is disclosed. The stage includes at least one rotor disk mounted inside a sectorized ring supported by a casing and including a circumferential flange radially clamped on an annular rail of the casing by a substantially C-shaped cross-section annular locking device which is axially engaged on the casing rail and on the flange of the ring. A substantially cylindrical heat shielding foil is interposed between the ring and the device. The foil or the device includes at least one extra thickness which respectively bears on the device, or the foil, to radially immobilize this foil.

Turbine or compressor stage for a turbojet

A locking member for a device for fastening ring sectors to an aircraft turbine engine casing is disclosed. The member has first and second clamping branches, which are connected together by curving joining portions, via a connecting branch. The joining portion of center thickness Ehas an inside surface of mean radius Rm, and the joining portion of center thickness Ehas an inside surface of mean radius Rm. Thickness Eis strictly smaller than thickness E, and mean radius Rmis strictly smaller than mean radius Rm

Asymmetrical member for locking ring sectors to a turbine engine casing

A stage of a turbine or compressor for a turbomachine including at least a vane disk surrounded with a sectorized ring supported by a casing and including a circumferential flange radially clamped on a rail of the casing by substantially C-shaped cross-section locks which are axially engaged on the casing rail and the flange of the ring is disclosed. The inner and outer walls of each lock includes radial bearing surfaces on the flange of the ring and the casing rail, respectively. The bearing surfaces only extend on a part of the width of the lock.
