Abstract

Skovlhjul (10) for en hydraulisk francisturbin hvor hvert skovlblad (13) har en utløpskant (16) som er sammenføyd med skovlhjulets ring (11) og består av et bøyd kantparti (110) anordnet nær et festepunkt (13) på denne utløpskant. Derved avgrenses et utvidet parti (130) på bladet (13), nær ringen (11), som reduserer påkjenningene på bladet. Partiet (130) reduserer særlig påkjenningskonsentrasjoner nær området hvor utløpskanten (16) er sammenføyd med ringen (11).
