Study of a Vertical Axis Wind Turbine Using Mechanism of Bird Wings : Part 7 Experimental Study of the Three Sheet-Wing Vertical Long Model
Details
Many birds increase by flapping the wing and the whole wing is flexibly moved this time. This movement produces a difference in the air resistance. The air is grasped enough, when the wing is moved in the downward direction. The air is released from the clearance of the wing, when the wing is moved upward. It is considered to apply this mechanism to the bird type wing of the wind turbine. In the paper, the Three Sheet-Wing Vertical Long Model is investigated experimentally. The effect of the vertical long type and the importance of the catching boards and the outer wings are clarified.
