WINDWHEEL HUNTING DAMPER Russian patent published in 2006 - IPC F03D7/04 

FIELD: wind power engineering.

SUBSTANCE: invention relates to devices designed for damping hunting of head with windwheel relative to tower of wind plant of horizontal-axial type. Invention is aimed at providing required orientation to wind and preset minimum hunting speed of windwheel. Windwheel hunting damper contains at least one hydraulic shock absorber and device converting rotary motions of windwheel nacelle into reciprocating motion of piston of hydraulic shock absorber. One end of hydraulic shock absorber is fastened on tower, and other end interacts with converting device.
