FIELD: wind power plants, wind-driven pump and compressor plants, windmills, butter churns, etc. SUBSTANCE: turbine has fixed rotor with vertical shaft whose arms carry adjustable blades and movable blade turn limiter. Rotor has device for setting blades to feathered pitch. Rotor arms are reinforced by means of ribs. There are also mechanical or electromagnetic stops for rotor sail-type blades. EFFECT: improved efficiency of wind power utilization and simplified design of turbine that dispenses with high supporting poles and wind-orienting devices; reduced metal input. 3 dwg
