Abstract
A turbine stage for a turbine engine includes a bladed wheel rotatable inside a sectorized ring of composite material carried by a casing. Each ring sector has a downstream circumferential rim held to bear radially against an annular tab that is engaged radially in an annular groove of the downstream circumferential rim of the ring with axial clearance, when cold, that is designed to be reduced to zero in operation when hot, and to enable the annular tab of the casing to be clamped axially in leaktight manner in the annular groove of the ring sector.

A turbine stage for a turbine engine, the stage comprising:
- a bladed wheel rotatable inside a sectorized ring made of composite material and carried by a casing, each ring sector having a downstream circumferential rim held to bear radially against an annular tab of the casing by a C-section fastener,
- wherein the annular tab of the casing is engaged radially in an annular groove in the downstream circumferential rim of the ring with axial clearance, when cold, that is designed to be reduced to zero in operation, when hot, and to enable leaktight axial clamping of the annular tab of the casing in the annular groove of the ring sector.
