FIELD: machine engineering.
SUBSTANCE: method of giving movement to the impeller consists in forming the main torque using the reaction of the inflowing fluid when the flow interacts with the main blades 5 arranged by the convex side to the flow and as much as possible changing its radial direction and the additional torque using an outflow liquid with further interaction of the flow with additional blades located concave sides to the flow.
EFFECT: increase in the efficiency of the hydroturbine due to additional energy extraction from the liquid at the outlet of the impeller.
