Abstract

"CONJUNTO DA PORTA DE ENTRADA PARA REDUZIR RUìDO DE UMA UNIDADE DE FORçA AUXILIAR (APU) CONTIDO DENTRO DE UMA AERONAVE". é fornecido um conjunto de porta de entrada e processo para redução de ruído a partir de uma unidade de força auxiliar (APU) contida dentro de um alojamento de aeronave. O conjunto de entrada inclui um duto de entrada, e uma porta. O duto de entrada é configurado, para se estender da unidade de força auxiliar ao alojamento de aeronave, e possui uma parede lateral que define uma passagem de fluxo, pela qual o ruído da APU se propaga. O atuador é disposto, pelo menos parcialmente, dentro do duto de entrada. A porta é acoplada ao atuador. O atuador é ainda configurado para girar seletivamente a porta entre pelo menos uma primeira posição, onde pelo menos uma parte da porta deflete o ruído da APU em uma primeira posição, e uma segunda posição, onde pelo menos uma parte da porta deflete o ruído da APU em uma segunda posição.
