Abstract
A turbine ring assembly includes ring sectors made of ceramic matrix composite forming a ring and a ring support structure. Each sector includes an annular base with, in a radial direction, an inside face and an outside face from which extend two attachment tabs held between two radial tabs of the structure. The assembly also includes, for each sector, at least two pins cooperating with one of the attachment tabs and the corresponding radial tab, and at least one pin cooperating with the other attachment tab and the corresponding radial tab. The first radial tab includes a first annular radial portion integral to the structure, and a removable second annular radial portion extending radially toward the center of the ring over a greater portion than said first radial annular portion, the portion extending beyond the first annular radial portion including orifices for receiving one of the pins.
