Abstract

"MéTODOS E DISPOSITIVOS PARA A REFRIGERAçãO LAMINAR DE COMBUSTORES DE MOTORES DE TURBINA A GáS". Um combustor (16) para um motor (10) de turbina a gás, inclui uma câmara de combustão (54) apresentando um eixo central (110) que se estende por dentro desta, um suporte (42) externo, um suporte (46) interno e um conjunto de domo (48). O conjunto de domo inclui uma placa de domo (72) que se estende entre ditos suportes interno e externo, e acopla um suporte interno e externo ao conjunto de domo. A placa de domo inclui pelo menos um lábio (202) da fenda de refrigeração, e pelo menos uma projeção de suporte (206), sendo que a pelo menos uma fenda de refrigeração é radialmente distanciada de dita pelo menos uma projeção de suporte de tal forma que um afastamento (210) é definido entre estes. O afastamento apresenta uma altura (H~ G~) medida entre dito pelo menos um lábio da fenda de refrigeração e a dita pelo menos uma projeção de suporte, dita altura do afastamento sendo substancialmente constante através de dito afastamento.
