Abstract

Structure de virole comportant une virole en céramique. Elle comprend des blocs en céramique 40 disposés en anneau qui ont, vus en plan, une forme rectangulaire, ont une surface intérieure arquée 42 qui délimite une partie du passage 38 d'écoulement des gaz chauds et sont munis sur leurs côtés amont et aval de surfaces en queue d'aronde 44, 46 obliques par rapport à la face 42, les blocs étant 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 butées fixes. L'invention est applicable, notamment, aux moteurs à turbine à gaz d'avions.
