F03D3/0481 - 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 and only with concentrating action, i.e. only increasing the airflow speed into the rotor
