Abstract

ABSORVEDOR ACúSTICO PARA MECANISMO DE PROPULSãO DE AVIãO. A presente invenção refere-se a um absorvedor acústico, que é apropriado especialmente para mecanismos de propulsão de aviões, possui uma estrutura tridimensional alveolar (11), que, ao ser empregada em um mecanismo de propulsão, absorve ruido do mecanismo de propulsão. A estrutura (11) apresenta uma série de alvéolos dobráveis (8), que são forma- dos por dobradura de um semimanufabricado plano.
