Beschreibung
Zusammenfassung:	A turbine ring assembly comprises a plurality of ring sectors (10) made of a ceramic matrix composite material and forming a turbine ring and a ring support structure (3) comprising a first and a second annular flange (32, 36). Each ring sector having a K-shaped cross section with an internal face defining the internal face of the turbine ring and an external face from which extend a first and a second S-shaped tab (14, 16). The internal faces (14b, 16b) of the tabs (14, 16) of each ring sector (10) rest against a portion of holding elements (40, 41, 50, 51) that are secured to the annular flanges (32, 36). The annular flanges (32, 36) comprise, on their face (32a, 36a) facing the tabs (14, 16) of each ring sector (10), a plurality of clamping flanges (61, 71, 81, 91) that are distributed circumferentially on the flanges, the external faces (14a, 16a) of the tabs (14, 16) of each ring sector (10) being in contact with two clamping flanges.
