FIELD: hydraulic power engineering. SUBSTANCE: horizontal rotor is mounted on vertical posts and carries sections built up of rectangular frames with hydrofoil-profile blades mounted for turning in parallel to rotor axis. Rotor is installed for vertical displacement. Frames are made in the form of collar beams with collars fixed on rotor shaft. Blades are mounted on collars for turning through 180 deg. Blade length is greater than external size of collars. Electric generator is coupled to rotor by means of flexible shaft and hydraulic drive. EFFECT: improved design. 2 cl, 4 dwg
