Abstract

um conjunto de anel de turbina compreende setores de anel (10) de material compósito com matriz cerâmica formando um anel de turbina (1) e uma estrutura de suporte de anel (3) comportando um primeiro e um segundo flanges anulares (32, 36) cada setor de anel tendo uma primeira e uma segunda abas (14, 16) mantidas entre os dois flanges anulares (32, 36) da estrutura de suporte de anel (3). um primeiro e um segundo elementos de retenção (40, 41) presos ao primeiro flange anular (32) sendo alojados em primeira e segunda aberturas (142, 143) da primeira aba (14) enquanto que um primeiro e um segundo elementos de retenção presos ao segundo flange anular (36) são alojados em uma primeira e uma segunda aberturas da segunda aba (16). uma folga radial está presente a frio entre as aberturas e a parte dos elementos de retenção presentes nas ditas aberturas. o primeiro e o segundo flanges anulares (32, 34) compreendem sobre sua face voltadas para a primeira e segunda abas (14, 16) uma pluralidade de porções de apoio (34, 38) repartidas de maneira circunferencial sobre os flanges, a extremidade (141. 161) das primeira e segunda abas (14, 16) de cada setor de anel estando a frio em batente radial com duas porções de apoio.
