Abstract

MOTOR DE TURBINA A GÁS, MÉTODO PARA PROJETAR UM MOTOR DE TURBINA A GÁS, E, MÓDULO DE TURBINA. E descrito um motor de turbina a gás que é utilizado em combinação com uma redução de engrenagem para reduzir a velocidade de uma ventoinha em relação à velocidade da turbina de baixa pressão. O motor de turbina a gás é projetado de maneira tal que a quantidade de pás na turbina de baixa pressão multiplicada pela velocidade da turbina de baixa pressão resulta em ruído operacional que fica acima de uma faixa sensível ao ouvido humano. São também revelados um método e módulo de turbina.
