WINDWHEEL Russian patent published in 2013 - IPC F03D1/02 F03D7/02 

FIELD: power industry.

SUBSTANCE: wind wheel includes a base with bearings, a horizontal shaft, blades, rotors having magnetic contact to stators installed on the base, and reduction gears. Rotors are connected to inlet shafts of reduction gears, on the outlet shafts of which additional blades are installed, which have the possibility of being rotated relative to the main axis. Profiles of the main and additional blades have the possibility of being superimposed on each other at rotation of additional blades. At strengthening of wind, voltage is supplied to stators, which leads to rotation of rotors, outlet shafts of reduction gears and rotation of additional blades accordingly.

EFFECT: windwheel design provides the possibility of changing the number of blades depending on wind speed, improvement of reliability due to absence of a rotating current terminal, provision of noncontact.
