Abstract
MÁQUINA DE FLUXO DE FLUIDO ESPECIALMENTE UMA TURBINA DE GÁS PENETRADA AXIALMENTE POR UM FLUXO DE GÁS QUENTE. A presente invenção refere-se a uma máquina de fluxo de fluido, especialmente uma turbina de gás, penetrada axialmente por um fluxo de gás quente, o eixo de rotor está circundando por segmentos de proteção de calor ou por placas de base das lâminas de rotor no lado de rotor. Dentro segmentos de proteção de calor e dentro das placas de base câmaras de ar de resfriamento estão providas, as quais comunicam umas com as outras e com uma fonte de ar de resfriamento, cujas câmaras comunicam pelo menos parcialmente com as folgas as quais estendem na direção longitudinal ou na direção periférica do eixo de rotor entre as lâminas de rotor adjacentes ou entre os segmentos de proteção de calor e as placas de base adjacentes das lâminas de rotor. Estas folgas estão fechadas por tiras de vedação de modo que uma entrada de ar de resfriamento no fluxo de gás quente seja somente possível nas extremidades das placas de base das lâminas de rotor que apontam ao contrário da direção de fluxo.
