ROTARY WIND TURBINE Russian patent published in 2019 - IPC F03D3/00 F03D3/04 

FIELD: power engineering.

SUBSTANCE: invention relates to wind power engineering. Rotor windmill consists of shaft 1 installed horizontally, working elements of which are fixed on it working blades 2, structurally representing a combination of rotor 3. Shaft 1 is located in bearings 4 fixed in bearing housings 5, which are fixed on posts 6 of support frame 7. Between supports 6 and working blades 2 on each side of rotor 3 on shaft 1 there are additionally installed bearings 8 in bearing housings 9, as well as guide plates 10 with holes for passage of shaft 1, to which bearing housings 9 and beams 11, made in the form of metal rods, which along their length are larger than radius 12 of working blades 2 rotation surface, are fixed. Between beams 11 located on both sides of rotor 3 on the length exceeding radius 12, guide 13 airflow is fixed inclinedly to working blades 2 and to form the adjustable airflow guide 14 with possibility of its rotation around horizontal shaft 1 and fixation in required position with the help of retainers 15 fixed on posts 6 of support frame 7. At one end of shaft 1 there is elastic coupling 16, which allows connecting to it the corresponding end of the horizontal rotor shaft of another similar rotor windmill. At the other end of shaft 1 there is drive pulley 17 connected by means of belt transmission 18 to pulley 19 of working mechanism 20.

EFFECT: invention is aimed at providing maximum use of surface air energy.
