Abstract

resumo “aparelho de controle de folga para um motor de turbina a gás e método para controlar folga de turbina em um motor de turbina a gás” trata-se de um aparelho de controle de folga para um motor de turbina a gás (10) que inclui: um invólucro de turbina anular (48) que tem superfícies interna e externa opostas (49, 51); um coletor anular (m) que circunda uma porção do invólucro da turbina (48), sendo que o coletor (m) inclui: uma porta de admissão (74) em comunicação fluida com o coletor (m) e a superfície externa (51) do invólucro da turbina (48), e uma porta de saída (52); e um cano de derivação (84) que tem uma extremidade a montante (86) acoplada à porta de saída (52), uma extremidade a jusante acoplada a uma fossa de baixa pressão e uma válvula (92) disposta entre extremidades a montante e a jusante, sendo que a válvula (92) é seletivamente móvel entre uma primeira posição, que bloqueia o fluxo entre as extremidades a montante e a jusante, e uma segunda posição, que permite o fluxo entre as extremidades a montante e a jusante. um método correspondente para controlar folga de turbina também é fornecido.
