FIELD: power engineering.
SUBSTANCE: this turbine comprises water duct 1 connected with top and bottom cases 3 and 6 accommodating impeller 2 with buckets 4 arranged regularly at the disc and made of two identical all-in-one metal sheets to produce the angle smaller than 180 degrees there between and stiffness rib on opposite side. Through hole is made at the centre of every sheet. Turbine impeller 2 shaft 5 is arranged on LH and RH interconnected stator column reinforced concrete supports. Stator sealing walls, inner surfaces of cases 3 and 6 and rings 11 secured at stator columns to cover the disc of impeller 2 form the toroid rectangular section channel.
EFFECT: simple and reliable high output turbine, longer life.
