FIELD: hydraulic engineering. ^ SUBSTANCE: invention is designed for converting kinetic energy of water flow of small rivers and tides. Proposed hydraulic turbine has housing and wheel with helical blade provided with flange in form of cylindrical spiral secured on blade for changing outreach of flange. ^ EFFECT: increased transmission of flow to wheel, reduced losses for friction against stationary housing, increased efficiency of turbine. ^ 2 dwg |
