Classic windmill - Cyclifier
n [HP}= A (wing) x v (wind)^3 / 1250; Assuming a wind with 4 bft (7 m/s), the result is approximately 30 HP. But only 50% of that power can be used for the technical process, because of losses due to friction (15 HP or 11,2kW). Every 6.5 m2 of wing surface generate 1 HP or 0.745kW. The rotation of the horizontal shaft is deflected downwards on ...
