Abstract

DISPOSITIVO PARA SILENCIAR UM MOTOR DE TURBINA A GáS PARA HELICóPTERO, E, MOTOR DE TURBINA A GáS PARA HELICóPTERO Em um motor de turbina a gás para helicóptero, rebordos (30, 32) definindo uma admissão de ar radial (34) são conectados ao longo de uma abertura (12a) de uma passagem de suprimento de ar de compressor de motor (12). Os rebordos de admissão de ar são pelo menos parcialmente formados por um atenuador de som (40, 42) calculado para atenuar freqüências de som produzidas pela rotação do compressor.
