Turbine ring incorporating elements of a ceramic composition divided into sectors
TLDR
In this paper, a turbine ring comprises an annular support in two parts and a ring of ceramic sectors for sealing purposes, which are interconnected by an axial groove and a sliding male part.Abstract:
A turbine ring comprises an annular support in two parts and a ring of ceramic sectors for sealing purposes. The two parts of the support are interconnected by an axial groove and a sliding male part. Each part comprises an axial annular groove in which is engaged a respective axial edge portion of each sector. The cooperating internal radial faces respectively of the edge portion and of the groove are circumferential, while the radially outer radial face of each sector comprises at least one flat zone. The corresponding face of each groove may be polygonal.read more

Turbine ring for a turbine machine
TL;DR: In this paper, the hollow metal ring 5 is protected internally by an annular heat screen, formed by segments made of ceramic 6, each of which is elastically fastened to the ring 5 by a screw 11 which passes through the ring and the segment 6 and whose head 11 t transmits to the segment six, which presses it against the ring.
