TURBINE ENGINE TURBINE ASSEMBLY

SAFRAN AIRCRAFT ENGINES, ...

1. A turbine assembly for a turbine engine, the turbine assembly comprising:a rotor disk having a plurality of blades made of ceramic matrix composite material;
a stationary nozzle made of ceramic matrix composite material arranged downstream from the rotor disk and comprising a plurality of nozzle vanes, each nozzle vane having an outer platform at an outer end, the outer platforms of the nozzle vanes together forming a nozzle ring around the nozzle vanes;
a turbine ring made as a single piece of ceramic matrix composite material having an inside face facing the outer ends of the blades of the rotor disk, the turbine ring being fastened to the nozzle ring in such a manner that the turbine ring and the nozzle ring together define an annular wall corresponding to the outer wall of a gas flow passage through the turbine; and
a casing comprising an outer casing and a support structure including a plurality of cylindrical rings, the casing made of material presenting a coefficient of thermal expansion that is strictly greater than the coefficient of thermal expansion of the ceramic matrix composite material forming the blades of the rotor disk, the stationary nozzle, and the turbine ring, the casing extending around the nozzle ring and the turbine ring, at least one of the nozzle ring and the turbine ring being connected to the outer casing and one of the cylindrical rings of the casing via at least one sliding connection having a degree of freedom to move radially such that the casing is movable relative to said at least one of the nozzle ring and the turbine ring solely in a radial direction that is perpendicular to a longitudinal axis of the turbine assembly without stressing said at least one of the nozzle ring and the turbine ring to which the casing is connected,
wherein the turbine ring connects at an upstream end of the turbine assembly to the outer casing and said one of the cylindrical rings via said at least one sliding connection.
