Abstract

câmara de pressão de entrada, e, motor de turbina a gás uma câmara de pressão de entrada para acoplar fluxo de ar de uma entrada de fluxo de ar radical para uma entrada de fluxo de ar axial para um compressor inclui uma chicana perfurada de entrada que inclui uma chicana geralmente cilíndrica que circunscreve a entrada do compressor e uma pluralidade de aberturas, cada abertura perfurando a chicana para passar o fluxo de ar da entrada de fluxo de ar radial para a entrada do compressor e uma pluralidade de palhetas de estagnação, cada palheta de estagnação contendo uma palheta geralmente em forma de arco que se estende próxima a chicana perfurada de entrada para estabelecer uma aproximação do fluxo estagnado em volta de toda a chicana perfurada de entrada para reduzir a distorção do fluxo de ar entre a entrada de fluxo de ar radial e a entrada do compressor axial.
