ASSEMBLED STRUCTURE OF TURBINE RING CONTAINING MULTIPLE RING SEGMENTS MADE OF COMPOSITE MATERIAL WITH CERAMIC MATRIX Russian patent published in 2019 - IPC F01D25/24 

FIELD: machine building.

SUBSTANCE: invention relates to a turbine ring assembly comprising an annular bearing structure and a plurality of annular segments (1) made of composite material with a ceramic matrix, wherein each annular segment (1) has a section forming annular base (2) with inner surface (3) defining inner surface of turbine ring, and outer surface (3a), from which wall (5) extends, forming inner cavity (6), in which retaining part (10) made of metal material is arranged, wherein retaining part (10) is connected to annular bearing structure and comprises main part (11), from which on each side in inner cavity (6) elastically deformable retaining elements (12) pass, wherein said retaining elements (12) thrust against wall (5), and retaining part (10) exerts pressure on annular segment (1) along radial (R) and axial (A) directions.

EFFECT: invention allows improving characteristics of gas turbine engines due to reduction of cooling flow, as well as reducing mechanical stresses to which annular segments are exposed during turbine operation.
