FIELD: turbines or turbomachines.
SUBSTANCE: object of the present invention is a turbine ring assembly comprising a plurality of sectors (1) of a composite material ring with a ceramic matrix, forming a turbine ring, and ring support structure (2) comprising two annular flanges (11a; 11b), between which fastening part (9) of each ring sector is retained, wherein each of the annular flanges of the ring support structure has at least two inclined portions (12a; 12b; 13a; 13b) resting on the ring sectors fastening parts, wherein said inclined sections form in the meridian section a non-zero angle relative to the radial direction (R) and the axial direction (A). At least one of flanges of ring support structure is made with possibility of elastic deformation.
EFFECT: reduced intensity of mechanical stresses, which are subjected to sectors of ring from composite material with ceramic matrix (CMC) during operation.
