<p>PURPOSE:To increase output under the constant revolution speed condition by increasing the pressure receiving area without increasing the blade wheel diameter of a wind mill. CONSTITUTION:A short cylindrical accelerating vane 15 is installed on a wind mill body 11 through a supporting plate 14 so as to be positioned in front (upstream side of wind) of a blade wheel 13. The wind is boasting-collected by the accelerating vane 15, and introduced into the blade wheel 13 having the smaller aperture (d) than the wind collecting diameter (D) of the accelerating vane 15.</p> |
