F03D3/0463 - CPC Classification

Classification description:

Wind motors with rotation axis substantially perpendicular to the air flow entering the rotor  having stationary wind-guiding means, e.g. with shrouds or channels having shield means on one side of the rotor fixed with respect to rotor, orientable together with augmenting action, i.e. the shield means intercepting an area greater than the effective rotor area
