WR POWER GENERATION PLANT Russian patent published in 2009 - IPC F03D3/02 

FIELD: engines and pumps.

SUBSTANCE: invention relates to power generation, namely, to wind-driven electric plants and can be used as a self-contained power source, in particular, on the roofs of building that feature a sufficient height. Proposed plant comprises electric generator coupled with shaped-blade rotary turbine vertical shaft, the turbine blades being arranged all over the turbine circumference. The said turbine is located inside an immobile device designed to produce wind flow and representing a cylindrical system with guide blades arranged along the plant circumference. The aforesaid device with the turbine represents several interjointed tiers mounted on each other. In each tier, the turbine is furnished with an upper and lower flywheels whereto the blades are attached. The immobile device designed to produce wind flow comprises the upper and lower bases whereto guide blades are attached. The central part of the turbine every tier accommodates a hollow pipe attached to the upper and lower flywheels. Note that turbine OD-to-hollow pipe diameter ratio makes 1.5 ÷ 2.5. The immobile device blades represent, in their cross section, a ring segment, while the turbine blade cross section features a sines curve shape.

EFFECT: higher efficiency, lower vibration and ease of operation.
