WIND TURBINE WITH AIR-BEARING STRUCTURES AND VARYING DIMENSIONS OF BLADES Russian patent published in 2020 - IPC F03D3/04 

FIELD: electricity.

SUBSTANCE: invention relates to wind power engineering. Wind turbine with air-bearing structures and varying dimensions of blades includes flat plates of blade tip, its stabilizing plane and support rings of wind turbine, to which blades are fixed. Flat blade tip plates, stabilizing plane and support rings of wind turbine are equipped with statically indeterminate pneumatic frame structures from air ducts of rectangular or round profile, made of composite materials with necessary internal partitions, providing independent tightness of all pipe sections between partitions of air-bearing pipes and closed volume with excessive gas pressure. Flat tips of blade tip, stabilizing plane and support rings of wind turbine are glued tightly by reinforced film on surface of each of them, forming multiple closed volumes with excess pressure of gas.

EFFECT: invention can be used for obtaining mechanical and electrical energy.
