ROTOR WIND ELECTRIC ASSEMBLY Russian patent published in 2008 - IPC F03D11/00 

FIELD: engines and pumps.

SUBSTANCE: invention refers to improvement of rotor wind electric assemblies /WEA/. Equipped with blades and electro generator, the WEA has blades the shape of which is created by a cross of two parabolas Y₁=K₁X^1/2; Y₂=2R₀+K₂X^1/2, where K₁≥1; K₂=/0,4÷0,8/K₁,_{or with one parabola Y1=K1X^1/2, K1≥1; at that the blades are equipped with valves in form of apertures; the apertures are covered with plugs which are held in place with flat springs attached to a rod; the rod is controlled with a centrifugal pendulum which controls power by partial opening or complete opening of apertures at a strong wind; at that ends of the blades are mechanically tied into a ring. The top of the blade is equipped with receptors of lightning protection via rotation axis and a cable connected to ground. Usage of the centrifugal pendulum facilitates control of power and provides protection of WEA. Receptors on the ends of blades connected via rotation axis and a cable to ground provide lightning protection of WEA. A ring form tie of the blades ends reduces noise produced by WEA.}

EFFECT: increased efficiency of a wind electrical assembly and efficiency of wind usage with simplification of the design.
