Abstract

conexão de pá de turbina guia de difusor para um compressor centrífugo. a invenção refere-se a uma montagem que consiste em um difusor (1) e um retificador de fluxo de ar (2) na saída de um compressor centrífugo de um motor à turbina, em que o dito difusor é substancialmente no formato de um disco anular duplo posicionado radialmente e dito retificador é uma parte toroidal dupla, disposto como uma extensão do disco duplo do difusor e curvado tal como para desviar o fluxo de ar na direção a jusante do motor, caracterizada pelo fato de que o dito retificador é fixado ao dito difusor por uma conexão posicionada imediatamente adjacente à superfície de contato das duas partes e é removível com o uso de uma ferramenta padrão, excluindo quaisquer outros meios de suporte.
