Abstract

isolamento de uma borda circunferencial de um cárter externo de turbomáquina de um setor de anel correspondente a invenção refere-se a um estágio de turbina de uma turbomáquina, compreendendo uma roda de rotor montada no interior de um anel setorizado portado por um cárter externo (4), o cárter externo (4) comportando pelo menos uma borda circunferencial (22) alojada nesta cavidade para fixação da extremidade a jusante (13) do setor de anel (6), caracterizado pelo fota de que a parede de fundo (16) da cavidade anular do setor de anel (6) permanece afastada radialmente da borda circunferencial (22) do cárter externo (4), de modo a dispor um espaço termicamente isolante entre as duas e comporta meios de posicionamento radial (24) sobre esta borda circunferencial (22).
