Abstract
"MéTODOS E DISPOSITIVOS PARA A REFRIGERAçãO DOS CONJUNTOS DE ROTOR EM MOTORES DE TURBINA A GáS". Um método permite a montagem de um motor de turbina a gás (10). O método compreende prover um conjunto de rotor (62) incluindo um eixo de rotor (26) e um disco de rotor (66) o qual inclui uma coroa (68) radialmente externa, um cubo (70) radialmente interno, e uma alma (72) integral estendendo-se entre estes, sendo que o conjunto de rotor pode girar ao redor de um eixo de rotação (28) que se estende através do eixo do rotor, e acoplar um retentor de disco (82) incluindo pelo menos um tubo de descarga (164) no disco do rotor sendo que o tubo de descarga se estende para fora a partir do retentor do disco para o bombeamento e então a descarga do fluido de refrigeração deste em uma direção a qual é substancialmente perpendicular com relação ao eixo de rotação.
