MAGNUS-ROTOR WINDMILL-ELECTRIC GENERATING PLANT Russian patent published in 2002 - IPC

FIELD: wind-power engineering. SUBSTANCE: vertical-shaft windmill-electric generating plant depending for its operation on Magnus effect has windwheel mounted on horizontal shaft, radial blades in the form of cylinders, and electric generator; operating mechanisms are made in the form of Savonius rotors mounted on cylinder shafts and rigidly coupled to them. Novelty is new relationship between geometric and kinematic parameters of plants which is as follows: where V_w is wind velocity; D_c and D_S-r is cylinder and Savonius-rotor diameter, respectively; n_wh is windmill speed; R_S-r is distance between shaft axis and point on Savonius rotor corresponding to mean value of VS-rp

with respect to rotor length; VS-rp is flow velocity on radius R_S-r during windwheel rotation. EFFECT: simplified mechanical design and circuit arrangement, enhanced economic efficiency. 1 dwg
