FIELD: energy converting facilities. SUBSTANCE: turbine is designed for converting flow energy into shaft rotation mechanical energy. Turbine blades are of special configuration providing reduction of hydraulic resistance and concentration of flow energy. Inner surface of each blade has semi-round curvilinear section and outer surface has streamlined section smoothly getting into water and getting out of water with practically no hydraulic resistance. Flow energy is efficiently concentrated on curvilinear inner surface of each blade in lower part of turbine. EFFECT: increased efficiency. 3 cl, 3 dwg
