Abstract

VEDAçãO DO DUTO DE ADMISSãO DA FUSELAGEM DE AVIãO, SISTEMA DE AMORTECIMENTO, E, MéTODO PARA FABRICAR UM SISTEMA DE AMORTECIMENTO. Uma vedação do duto de admissão da fuselagem do avião amortece vibração em um elemento de vedação de compressão de uma entrada da caixa do motor. A vedação do duto de admissão inclui uma perna interna que encaixa uma parte estacionária do elemento de vedação de compressão e compreende uma pluralidade de câmaras de pressão para permitir que ar de entrada passe através da perna interna. A vedação do duto de admissão também inclui uma perna externa que encaixa uma parte móvel do elemento de vedação de compressão e compreende urna pluralidade de defletores e uma pluralidade de ligamentos. Os defletores desencaixam da parte móvel do elemento de vedação de compressão em uma pressão limiar, de tal maneira que o ar de entrada desvie da entrada da caixa do motor. Os ligamentos permanecem em contato com a parte móvel do elemento de vedação de compressão, e amortecem vibração da mesma, a uma pressão igual ou acima da pressão limiar.
