Abstract (en)

[origin: WO2017103451A1] A plurality of CMC ring sectors forms a turbine ring. A support structure (3) comprises two annular flanges (32; 36). Each ring sector has an outer face with two tabs (14; 16) held between the annular flanges (32; 36) of the support structure. Each tab comprises a projecting portion (140; 160) facing a flange cooperating with a housing (320; 360) present on the flange, and an opening (15; 17) in which there is accommodated, with a clearance, a holding element (40a; 40b) that has a higher thermal expansion coefficient than the CMC and is secured to the flange. The housing has two portions (360a; 360b) abutting on the projecting portion and inclined relative to the radial direction (DA) and the axial direction (RA).
