Abstract

"TUBO DE DESCARGA DE HéLICE VARIáVEL DE TURBO-HéLICE". Trata-se de um tubo de descarga de exaustão de turbo-hélice (28) que inclui um conduto da hélice (40) definido entre a nacela da hélice (32) e a carenagem do motor principal (30). O conduto (40) inclui uma saída arqueada (42) na borda traseira (44) da nacela (32) . Uma aba móvel (46) é disposta em uma parte menor do conduto da hélice (40), com uma parte maior restante do conduto da hélice possuindo uma área de fluxo constante. A aba (46) pode ser movida entre posições guardada e disposta para localmente diminuir a área de fluxo dentro do conduto (40) para atenuação de ruído.
