Turbine ring assembly

A turbine ring assembly comprising:

• a plurality of ring sectors forming a turbine ring, each ring sector being made of ceramic-matrix composite material and having, along a section plane defined by an axial direction and a radial direction of the turbine ring, a portion forming an annular base with, in the radial direction of the turbine ring, an inner face defining the inner face of the turbine ring and an outer face from which a first attachment tab and a second attachment tab protrude;
• a ring support structure, the ring support structure being made of metal and including a central shroud from which a first radial clamp and a second radial clamp protrude between which the first attachment tab and the second attachment tab of each ring sector are maintained;
• a first annular flange;
• and
• a second annular flange disposed upstream of the first annular flange with respect to a direction of an air flow intended to pass through the turbine ring assembly,
• wherein the first and second annular flanges each respectively have a first free radial end and a second radial end opposite to the first free radial end, the first free radial end of the first flange bearing axially against the first attachment tab, the first free radial end of the second annular flange being distant from the first free radial end of the first annular flange in the axial direction,
• wherein the second radial ends of the first annular flange and second annular flange are removably fastened to the first radial clamp of the central shroud of the ring support structure such that the second radial end of the first annular flange is sandwiched between the first radial clamp of the central shroud of the ring support structure and the second radial end of the second annular flange,
• wherein the first annular flange and the second annular flange are shrink-fitted to the ring support structure, the second radial end of the second annular flange abutting an inner surface of the central shroud of the ring support structure in the radial direction, and a portion of the first annular flange abutting the ring support structure in the radial direction, and
• wherein one of the second radial end of the first annular flange and the second radial end of the second annular flange presents a contact abutment protruding in the axial direction and abutting axially the other of the second radial end of the first annular flange and the second radial end of the second annular flange.
