Abstract

PURPOSE: To improve the performance of a windmill by separately designing so that the inner and outer surfaces of a blade can be suitable for respective functions in the case of plan view of a Savonius windmill and producing the blade by their compound integration. CONSTITUTION: The blades A, B of a Savonius windmill are separately designed by positioning symmetrically holding a center line therebetween so that the respective length of the straight line part 1L of the outer surface of the blades A, B and the straight line part 2L of their inner surface can be suitable for respective functions. At the time of design, these blades A, B are compounded and integrated by giving an angle 3 between the straight line part 1L of the outer surface of the blades A,B and the straight line part 2L of their inner surface and changing the joining angle of wind directions Wb,Wc and therefore selecting so that the impulse direction applied to the are 3 of the blade B may be most suitable. Thereby, the performance of the windmill can be improved.

FIG. 3 is called a Bach type Savonius,
It is a plane sectional view of a two-blade impulse type wind turbine. Wings (hereinafter referred to as blades) A. B is located symmetrically with respect to the center line as shown in the figure. There is a disc above and below to attach the blade, but C is the lower disc. The wind direction Wa hits the straight part of the blade A (shown by 1.2L), changes its direction to the wind direction Wc, merges with the wind direction Wb, and urges against the curved part 4 of the blade B (hereinafter referred to as R). give. In the case of the two-bladed impulse type wind turbine, the maximum impulse is received when the center line on the drawing is at a right angle (that is, the illustrated position) with respect to the wind directions Wa and Wb. When the wind turbine turns 180 °, the blade A comes to the position of the blade B shown in the figure, and the same impulse is applied. This windmill is made by bending a single plate.

FIG. 2 shows an improved version of the Bach type Savonius. Blade A. In B, a thickness is added to the rounded portion as shown by a diagonal line. Therefore, the straight portion 1.2L of the blade shown in FIG. 3 can be considered separately as the straight portion 1L of the outer surface and the straight portion 2L of the inner surface of the blade. Since 1L is obviously longer than 2L, Wa. The air volume of Wc is 1.2L in Fig. 3.
More than. Therefore, there are many impulses for the R4. As is clear from FIG. 2, the outer surface of the blade fulfills the air collecting function, and the function is enhanced by adding the thickness of the shaded portion.

The thickness is also added between them as indicated by the diagonal lines, and is shown by the corner 3. In the case of FIG. 1, by changing the angle of W3. The merging angle of Wc changes, hence blade B
It is possible to select the direction of the impulse applied to the radius 4 of the above so as to be optimum.
