MODULAR WIND WHEEL Russian patent published in 2018 - IPC F03D1/02 F03D1/06 F03D7/02 

FIELD: power engineering.

SUBSTANCE: invention relates to a wind wheel. Modular wind wheel contains arc-shaped blades, which are located around the wind wheel axis of rotation, each of which is connected with a fastening element located along the wind wheel axis of rotation. Along the wind wheel axis of rotation front and rear shafts are installed, and the wind wheel is configured to be mounted on a support by means of a fastening assembly and consists of a front and rear modules of the same mass, wherein the front module is made approximated into a cone shape and rigidly fixed onto the front shaft, and the rear module is made approximated into the shape of a truncated cone with a truncated portion diameter equal to the front module base diameter and rigidly fixed onto the rear shaft. Front shaft front end is configured to be mounted in the support mounting assembly, and its rear end is made projecting beyond the base of the front module with the possibility of fastening to the two-rotor generator front drive shaft. Rear shaft front end is made protruding beyond the rear module truncated portion with the attachment to the two-rotor generator rear drive shaft, and its rear end is configured to be mounted in the support mounting assembly, wherein the each module is made with possibility of free rotation about the modular wind wheel longitudinal axis of rotation. Modular wind wheel is made with possibility of free rotation about a vertical axis on which its center of mass is located, wherein the rear module arcuate blades ascending spirals direction is made counter-current with respect to the front module arcuate blades ascending spirals direction, and the number of arcuate blades ascending spirals sets in each module is three, wherein the twisting angle of each spiral is 360°.

EFFECT: invention is aimed at increase in the wind energy use factor.
