Structure de virole comportant une virole en ceramique. Elle comprend des blocs en ceramique 40 disposes en anneau qui ont, vus en plan, une forme rectangulaire, ont une surface interieure arquee 42 qui delimite une partie du passage 38 d'ecoulement des gaz chauds et sont munis sur leurs cotes amont et aval de surfaces en queue d'aronde 44, 46 obliques par rapport a la face 42, les blocs etant maintenus en position par des organes de support annulaires 54, 56 qui appliquent aux blocs une composante de force radiale en les repoussant contre des butees fixes. L'invention est applicable, notamment, aux moteurs a turbine a gaz d'avions.read more

Method for the manufacture of a ceramic turbine ring integral with a metallic annular carrier
TL;DR: In this article, a method of manufacturing a turbine ring rigid with an annular metallic carrier is described, which includes the steps of (a) molding a ceramic member in a predetermined shape, locating the ceramic member produced in step (a), and (b) rotating the mould and moulding under centrifugal action a metallic material around the member, the rotation continuing until the metallic member has solidified.
