FIELD: wind-power engineering; conversion of air flow energy into mechanical energy fed to electric generator.
SUBSTANCE: proposed vortex-type windmill-electric power unit has tower, air intake, air offtake, and rotary working element connected to electric generator. Tower is positioned in downwind direction; working element is made in the form of parallel cylindrical rotors so that space crossing their axes of revolution is disposed in parallel with inlet section plane of tangential air intake made in the form of two symmetrical ducts turning into helical air ducts; air offtake of tower communicates with inner spaces of both rotors and protrudes outside on rear end of tower to low air pressure zone through air offtake ducts.
EFFECT: enhanced efficiency and simplified design of unit.
