Abstract

CONJUNTO DE ANEL DE TURBINA O conjunto de anel de turbina compreende uma pluralidadede setores de anel (10) em uma única peça de material compósito de matriz cerâmica e uma estrutura de suporte de anel, cada setor de anel tendo uma primeira parte (12) formando base anular com uma face interna definindo a face interna do anel da turbina e uma face externa a partir da qual se estendem duas partes formandoflanges (14, 16), cujas extremidades são encaixadas nos alojamentos da estrutura de suporte de anel. Os setores de anel (10) são de seção sensivelmente em forma de pi e as extremidades (14a, 16a) dos flanges (14, 16) são mantidas sem jogo radial pela estrutura de suporte de anel. Preferivelmente, os flanges (14, 16) têm, em seção meridiana, um comprimento livre pelo menos igual a 3 vezes sua largura média.
