Abstract

"BOCAL DE EXAUSTãO DE MISTURADOR DUPLEX" Um bocal de exaustão de motor de turbo-ventilação (30, 32) inclui misturadores externo e interno cooperantes (36, 38) . O misturador externo (36) inclui lóbulos externos alternativos (36a) e calhas externas (36b) . O misturador interno (38) inclui lóbulos internos alternativos (38a) e calhas internas (38b) . As extremidades frontais dos misturadores externo e interno (36, 38) ficam espaçadas entre si no sentido radial, e extremidades longitudinais dos misturadores são ligadas entre si de modo a definir uma saída (40) do bocal para a descarga de um fluxo de exaustão.
