Abstract:
A turbine ring assembly includes ring sectors forming a turbine ring, and a ring support structure having two annular flanges, each ring sector having a portion forming an annular base with an inner face defining the inside face of the turbine ring and an outer face from which there project at least two tabs, the tabs being retained between the two annular flanges. Each tab of the ring sectors includes a projecting portion on its face situated facing one of the two annular flanges, this projecting portion co-operating with a housing present in the annular flange. Each tab of the ring sectors includes an opening in which there is received a portion of a retention element secured to the annular flange situated facing the tab. The retention element is made of a material having a thermal expansion coefficient that is greater than that of the material of the ring sectors.

Claim (Index 1):
A turbine ring assembly comprising a plurality of ring sectors ( 10 ) made of ceramic matrix composite material forming a turbine ring, and a ring support structure having two annular flanges, each ring sector having a portion forming an annular base with an inner face defining the inside face of the turbine ring and an outer face from which there project at least two tabs, the tabs of each ring sector being retained between the two annular flanges of the ring support structure, wherein each tab of the ring sectors includes a projecting portion on its face situated facing one of the two annular flanges, said projecting portion co-operating with a housing present in the annular flange, and wherein each tab of the ring sectors includes at least one opening in which there is received a portion of a retention element secured to the annular flange situated facing said tab, clearance being present between the opening of said tab and the portion of the retention element present in said opening, said retention element being 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, and wherein the housing in the annular flange presents at least first and second sloping portions bearing against the projecting portion co-operating with said housing, said first and second sloping portions, when observed in meridian section each forming a non-zero angle relative to the radial direction and relative to the axial direction.
