Abstract

Un silenciador de escape de un turbomotor, caracterizado por comprender un dispositivo que absorbe por fortación las energías sonoras de frecuencia superior a 500 Hz, constituido por pantallas perfiladas guarnecidas con materiales porosos o fibrosos, así como un dispositivo atenuando las frecuencias inferiores a 500 Hz, constituido por resonadores asociados, de los cuales cada uno está adaptado a una frecuencia tal, que el conjunto cubra todas las frecuencias inferiores a 500 Hz, estando establecidos dichos resonadores alrededor de una campana, cuyos flancos estan perforados y que prolonga el tubo de escape del turbomotor.
