WIND-ELECTRIC POWER PLANT TOWER Russian patent published in 1997 - IPC

FIELD: wind-electric power engineering; towers for wind-electric power plants and beacons. SUBSTANCE: tower has top and bottom bases, polyhedral tube enclosing tower interior and provided with ports on each face communicating with tower interior; ports are arranged in helical manner within tower height H counted from top base and determined by equation given in description of invention. Ports are spaced apart on helical line at distance determined from equation given in description of invention. Tower is divided lengthwise into a number of sections whose interiors are intercommunicating; enclosed space is provided in at least one of them communicates with inner space of at least one adjacent section ports through calibrated-resistance channels; ports may be arranged along right- or left-handled helical line. Tower ports are greater in height or equal to their width and may be made round, oval, or rectangular with rounded corners; at least several ports are large enough to pass attending personnel; ports in tower may be closed with screens either throughout entire height or only to cover helical line with one-pitch length measured from top base of tower. EFFECT: improved design, enlarged functional capabilities. 13 cl, 8 dwg
