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 first and second annular flanges, each ring sector having first and second tabs, the tabs of each ring sector being held between the two annular flanges of the ring support structure. Each of the first and second tabs of the ring sectors has an annular groove. Each of the first and second annular flanges of the ring support structure has an annular projection received respectively in the annular groove of the first tab or in the annular groove of the second tab of each ring sector. A resilient element is interposed between the annular projection of the first flange and the annular grooves of the first tabs, and also between the annular projection of the second flange and the annular grooves of the second tabs.
