Abstract

resumo patente de invenção: "sistema de injeção de fluido de resfriamento externo em um motor de turbina a gás". um sistema de injeção de ar de fluido de resfriamento (40) para uso em um motor de turbina a gás (10) inclui em uma fonte de fluido de resfriamento externa (42), pelo menos um tubo de resfriamento de rotor (46), que é utilizado para injetar o fluido de resfriamento a partir da fonte em uma câmara de rotor (rc), um sistema de tubulação (44) que fornece comunicação por fluido entre a fonte e o(s) tubo(s) de resfriamento de rotor, um sistema assoprador (50) para transportar o fluido de resfriamento através do sistema de tubulação e o(s) tubo(s) de resfriamento de rotor, para dentro da câmara de rotor, e um sistema de válvula (48). o sistema de válvula é fechado durante a operação de motor de carga total para impedir que o fluido de resfriamento proveniente da fonte passe através do sistema de tubulação, e abre durante menos do que a operação de motor de carga total para permitir que o fluido de resfriamento proveniente da fonte passe através do sistema de tubulação.
