MAGNUS TYPE WIND POWER GENERATOR
First Claim
1. - A Magnus type wind power generator comprising horizontal rotary shaft that transmits a rotation torque to a power generating mechanism, a required number of rotary columns that are disposed radially from said horizontal rotary shaft, and driving motors that rotatively drive said respective rotary columns about axes thereof, and a required number of flow directing planes are attached to a back of said horizontal rotary shaft in a predetermined position from said horizontal rotary shaft, wherein Magnus lift is generated by interactions among rotations of said respective rotary columns and said flow directing planes;
- and wind power rotates said horizontal rotary shaft to drive said power generating mechanism, wherein said Magnus lift generated by interactions between said rotations of said respective rotary columns and said flow directing planes is increased by generating air flow upon an outer peripheral surface of said rotary columns and said flow directing planes;
therefore increasing a rotation torque of said horizontal rotary shaft which drives said power generation mechanism and increasing power generation efficiency of a wind power generator in a wind speed range from low wind speed to relatively high wind speed;
wherein said air flow directing planes are installed in 135°
with respect to horizon in half-planes or airfoils, respective to said back of said rotary columns;
therefore increasing said Magnus lift and reducing wind noise;
wherein said wind power generator further comprises wind power generator caps comprising diameters larger than of a diameter of said rotary columns and wherein said wind power generator caps are installed in an extreme end of said columns.

Abstract
A Magnus type wind power generator (A) comprising a horizontal rotary shaft (3) for transmitting torque to a power generating mechanism (2), rotary columns (5), flow directing plane (7) installed at main shaft (3), driving motors (15) for rotatively driving the respective rotary columns (5) around the axes thereof, which the relative action between rotation of each rotary column (5) and wind produces Magnus lift, which rotates the horizontal rotary shaft (3) so as to drive the power generating mechanism (2). Firstly, air flow directing plane (7), installed to direct flow to the low pressure area so as to cause another delay and eventually increase the Magnus lift. Secondly, the crossed spiral on the surface of the cylinder (6) provided to generate more air flow in three directions upon the rotary cylinder (5) increases the Magnus force.
