More Information
Summary:A turbine ring assembly includes both a plurality of ring sectors made of ceramic matrix composite material forming a turbine ring, and also a ring support structure. Each ring sector includes a portion forming an annular base with an inner face defining the inside space of the turbine ring and an outer face from which an attachment portion of the ring sector extends for attaching it to the ring support structure. The ring support structure includes two annular flanges between which the attachment portion of each ring sector is held. Each annular flange of the ring support structure presents at least one sloping portion bearing against the attachment portions of the ring sectors, the sloping portion, when observed in meridian section, forming a non-zero angle relative to the radial direction and relative to the axial direction.
