Abstract
A turbine ring assembly includes 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 tabs. The first tab includes an annular groove in which there is received an annular projection of the first flange. The second tab of each ring sector is connected to the ring support structure by a resilient retention element. The second tab includes an opening in which there is received a portion of a retention element secured to the second annular flange of the ring support structure. The retention element is made of a material having a coefficient of thermal expansion that is greater than the coefficient of thermal expansion of the ceramic matrix composite material of the ring sectors.
