Abstract
A turbine ring assembly includes a ring support structure and a plurality of ring sectors made of CMC material and forming a turbine ring, each ring sector including an annular base with respective end portions having edges that are held facing an edge of the end portion of the annular base of a sector that is adjacent in the turbine ring. The assembly includes resilient holder devices for holding the ring sectors in position on the ring support structure, and each resilient holder device includes a spring element present beside the outside face of the ring support structure.
Claims6
A turbine ring assembly comprising a ring support structure and a plurality of ring sectors made of ceramic matrix composite material making up a turbine ring, each of the plurality of ring sectors comprising an annular base with, in a radial direction of the turbine ring, an inside face defining the inside face of the turbine ring and an outside face facing the inside face of the ring support structure, each said annular base including at each circumferential end a circumferential edge that is held facing a circumferential edge of the circumferential end of the annular base of an adjacent one of the plurality of ring sectors in the turbine ring, wherein the assembly comprises resilient holder devices, each of the resilient holder devices exerting a force on the circumferential ends of two adjacent ring sectors of the plurality of ring sectors, holding said two adjacent ring sectors of the plurality of ring sectors in position, and wherein each of the resilient holder devices comprises a spring element present beside the outside face of the ring support structure,
- wherein the turbine ring assembly comprises a plurality of gaskets, each of the plurality of gaskets extending axially over the circumferential ends of two adjacent ring sectors of the plurality of ring sectors at the facing edges of said ends, the resilient holder devices exerting force that holds each of the plurality of gaskets in contact with the circumferential ends of two adjacent ring sectors of the plurality of ring sectors, wherein the inside face of each of the plurality of ring sectors is coated with an abradable material layer.
