Abstract
Patente de Invenção:"ROTOR PARA UMA MáQUINA DE FLUXO HIDRáULICO DO TIPO FRANCIS". A invenção se refere a um rotor para uma máquina de fluxo hidráulico do tipo francis especialmente para uma turbina hidráulica com um cubo do rotor (1.1), uma coroa do rotor (1.2) e uma série de pás (1.3); cada pá (1.3) apresenta um canto de entrada (1.3.1) e um canto de saída (1.3.2); o canto de saída (1.3.2) de cada pá (1.3) é curvado num ponto (C), nas imediações do cubo do rotor (1.1) de tal maneira que a continuação do desenvolvimento (1.3.3) do canto de saída (1.3.2) se encontra com o cubo do rotor (1.1) num ponto (B), que está situado fluxo abaixo em relação a um ponto de incidência (A), que resultaria sem a curvatura do canto de saída (1.3.2).
