Abstract

"ORIFìCIO PARA O ALìVIO DA TENSãO NAS PALHETAS DO ROTOR DE TURBINAS FRANCIS". é descrito um rotor (20) para uma turbina hidráulica tipo Francis (18), no qual cada uma das palhetas (38) apresenta um bordo de saída (44) com dois rasgos de alívio da tensão (46) cortados através da palheta (38) desde o bordo de saída (44) adjacente à coroa (36) e a cinta (40). Cada um dos rasgos (46) apresenta uma abertura (48) contra o bordo de saída (44) e cada um dos rasgos (46) se estende por uma distância predeterminada desde o bordo de saída (44) para dentro da palheta (38).
