Abstract

"ESTRUTURAS DE ESPIRAL E LâMINAS DE TURBINA". Os aperfeiçoamentos são feitos no espiral de turbina e nas lâminas de turbina. A estrutura de espiral para as turbinas radiais é caracterizada pelo espiral acima possuindo uma razão de largura de espiral entre a largura na direção radial (<30>R) e a largura na direção de rotação (B) variando de <30>R/B = 0,3 a 0,7. é adicionalmente caracterizado pela configuração na qual as lâminas de turbina possuem áreas recortadas nos cantos de lâmina por uma quantia prescrita, que são fornecidas na borda de entrada no lado de proteção e no lado de cubo onde o gás operacional flui.
