SAIL WING TYPE WINDMILL AND OPERATION METHOD OF SAME

摘要

The sail wing type windmill is provided with a rudder (4) able to constantly facing to the wind direction controlled by a turn table (42) having a twin vaned tail wing (41) and a concave upwardly curved lead rail (43). The vertically shafted windmill has several sail type wing blades (24) each of them can develop or shrink its surface to face or offset the wind direction following the up and down motion of the end roller of the connecting rod (34) along the lead rail (43). The produced rotating torque by individual wing blade (24) is imparted to a centrifugal fly wheel hub (1) from time to time and this non-uniform torque and unstable rotating speed of the windmill is unified and governed stably by the fly wheel effect of a plurality of fly wheels (11) filled with a weighty substance.
