<P>PROBLEM TO BE SOLVED: To provide a windmill for wind power generation of low noise, easy maintenance and inspection, high efficiency, simple structure, and low cost. <P>SOLUTION: In this windmill F for wind power generation, a rotary blade A is formed of a wind receiving gutter 1, a main blade 2, and a subsidiary blade 3, and it is coupled to a vertical rotary shaft 5 of the windmill by means of blade support shafts 4. Three of the rotary blades A are combined to be driven as wind force is added. Out of force added to the main blades 2 and the subsidiary blades 3 placed in flow of wind, lifting force that is perpendicular to the flow and resistance force added in parallel to the wind receiving gutters 1 placed in the flow are both utilized. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
