Abstract

resumo “turbomáquina, tal como um turborreator ou um turbopropulsor de avião” a presente invenção trata de uma turbomáquina, tal como turborreator ou um turbopropulsor de avião, que compreende um cárter (10) de ventoinha a parede (12) sensivelmente cilíndrica que circunda as pás da ventoinha, e pelo menos dois painéis anulares (18, 20) de isolação acústica montados radialmente no interior da referida parede (12), sendo que um primeiro painel (18) está montado a montante da ventoinha, um segundo painel (20) está situado a jusante do primeiro painel (18) e que porta uma camada interna (42) em material suscetível de ser submetido à abrasão situada diante das extremidades radialmente externas des pás da ventoinha, caracterizada pelo fato que os dois painéis anulares (18, 20) formam um único conjunto estrutural.
