Abstract

"RODA E MáQUINA HIDRáULICA DE TIPO FRANCIS". Esta roda de tipo Francis compreende uma coroa, uma cinta, e pás (2) que se estendem entre a coroa e esta cinta. O ângulo (<225>~ 24~) entre a velocidade linear (U, D~ 224~) de uma pá (2) e a linha mediana (25,<30>~ 224~) desta pá (2) ao nível de sua extremidade de fuga (22) tem, na proximidade do ponto de fixação (224) da pá (2) sobre a cinta, um valor compreendido entre 20 e 25<198>. Isto permite obter um rendimento satisfatório da máquina, enquanto que sua potência equivalente sob uma carga elevada pode ser aumentada.
