Turbine ring assembly with resilient retention when cold

A turbine ring assembly comprising a plurality of ring sectors made of ceramic matrix composite material forming a turbine ring and a ring support structure having first and second annular flanges, each ring sector having an annular base forming portion having an inner face defining the inside face of the turbine ring and an outer face from which there extend first and second tabs, the tabs of each ring sector being retained between the first and second annular flanges of the ring support structure;

• wherein the first tab of each ring sector includes an annular groove in its face facing the first annular flange of the ring support structure, the first annular flange of the ring support structure including an annular projection on its face facing the first tab of each ring sector, the annular projection of the first annular flange being received in the annular groove of the first tab of each ring sector, clearance being present when cold between the annular projection and the annular groove;
• wherein at least the second tab of each ring sector is connected to the ring support structure by at least one first resilient retention element;
• and
• wherein the second tab of each ring sector includes at least one opening in which there is received a portion of a second retention element secured to the second annular flange of the ring support structure, clearance being present when cold between the opening in the second tab and the portion of the second retention element present in said opening, said second retention element being made of a material having a coefficient of thermal expansion that is greater than a coefficient of thermal expansion of the ceramic matrix composite material of the ring sectors.
