WIND MOTOR WITH AIR-CARRYING STRUCTURES Russian patent published in 2007 - IPC F03D3/04 

FIELD: wind-power engineering; wind motors at vertical axis of rotation of wind turbine; generation of mechanical and electrical energy.

SUBSTANCE: novelty of invention consists in use of film materials at different physical-mechanical properties for making the tips and movable planes of each blade of wind turbine, bearing rings and wind guide shields. Said components are made in form of one or several solid hollow hermetic cavities filled with gas mixture at different internal pressure; these cavities are interconnected forming volume of required structure which is covered with external film over boundaries; gaps between external film and cavities formed beforehand are also hermetic and are filled with gas mixture at different internal pressure.

EFFECT: increased utilization factor; reduced usage of materials.
