Abstract

"SEPARADOR DE PARTìCULAS INERCIAL, SISTEMA DE SUPRIMENTO DE AR PARA UM MOTOR DE TURBINA A GáS, E, MOTOR DE TURBINA A GáS" Um separador de partículas inercial (IPS) para uma boca de sino de admissão que acopla um espaço de pressão de ar de admissão a um compressor em um motor de turbina a gás, no qual o IPS remove partículas de ar dentro de escoamento de ar invertido que passa através de no mínimo uma abertura em boca de sino na boca de sino de admissão para o interior de aberturas de sangria de capuz em um capuz para o compressor, que compreende: no mínimo um defletor que se salienta de cada abertura em boca de sino posicionada para dobrar uma corrente de escoamento de ar invertida através da abertura em boca de sino até um grau que força partículas para fora da corrente de escoamento de ar invertida e para o interior do espaço de pressão de ar de admissão.
