Abstract
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 having two annular flanges, each ring sector having two tabs held respectively between the two annular flanges of the ring support structure. The two annular flanges of the ring support structure exert stress on the tabs of the ring sectors. One of the flanges of the ring support structure is elastically deformable in the axial direction of the turbine ring. The turbine ring assembly further includes a plurality of pegs engaged both in the annular flanges of the ring support structure and in the tabs of the ring sectors facing the annular flanges.
