F03D3/0472 - 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 orientable with respect to the rotor

Sub-classes:

F03D3/0481 » {and only with concentrating action, i.e. only increasing the airflow speed into the rotor } 29
F03D3/049 » {with augmenting action, i.e. the shield means intercepting an area greater than the effective rotor area} 14
