Abstract (en)
[origin: WO2011073570A1] The invention relates to a turbine stage for a turbine engine, including an impeller rotating inside a sectorised ring (54) made of a composite material supported by a housing (14), each ring sector including a downstream circumferential edge (52) held radially resting on an annular tab (56) which is radially inserted in an annular groove (50) of the downstream circumferential edge (52) of the ring (54) having axial play when cold, defined to be cancelled out when hot during operation and to allow sealed axial clamping of the annular tab (56) of the housing (14) in the annular groove (50) of the ring sector.
