The turbine has a blade (10) mounted in rotation around an axis in a casing comprising a metallic ring (16) fixed around a turbine rotor. An internal cylindrical surface of the casing is covered with a layer (18) of abradable material. A peripheral shroud (26) is slidably mounted at apex of the blade and partially housed and guided in an annular groove (30) of the ring (16). |
