WIND-POWER STATION (SAIL) Russian patent published in 1998 - IPC

FIELD: electrical engineering. SUBSTANCE: the station may be assembled of one or several wind propulsors. Each station propulsor is assembled of individual components (sails, rods, halyards) directly on a suspension using four cables forming a power flexible shaft linked with a bearing. This bearing is fastened by means of a clamp on horizontal cable, which is tensioned between two or three high masts. The windmill proper is assembled by introduction of two strong rods between the four cables of the flexible shaft perpendicularly to each other and to the flexible shaft. These two rods clamped on the flexible shaft form a single spider, and another spider is similarly assembled lower, to the sail height. Four sails are suspended between these two spiders (from their arms), four sails since there are only four arms here. But the sails are suspended in such a manner that moment of one of the four sails would act on the flexible shaft the whole time, transmitting its rotation to generator installed below. It is effected due to the fact that the sail vertical edge, which is remote father ahead from the center, serves as if a hinge relative to which the whose sail may have oscillatory motions, and the other vertical edge is lashed on to the carriers. The free ends of these carriers are lashed on to the vertical outer edge of the adjacent sail. The width of the sail and length of its carriers should have a slack but such that maximum efficiency of the working stroke would be attained. At such a taken up slack of the carrier the open sail accomplishes the working stroke, and the tree other sails are making ready for this stroke. EFFECT: enhanced efficiency of windmill, simplified design, reduced expenditures connected with assembly and construction. 3 dwg
