Title:
WIND TUNNEL ROTATING VANE
Document Type and Number:
WIPO Patent Application WO/2014/057810
Kind Code:
A1
Abstract:
[Problem] To provide a wind tunnel rotating vane having a novel configuration that is a complete change from conventional configurations, which have reached a limit in terms of rotational efficiency and electrical generation efficiency. [Solution] When the axis-proximal portion (16) of the wind-receiving surface (14) of a given blade (12) of a wind tunnel rotating vane (10) that receives wind and rotates within a wind tunnel (20) has rotated to a position perpendicular to the wind blowing through the wind tunnel (20), the wind blowing in the wind tunnel (20) passes through ventilation holes (1) and strikes the wind-receiving surface (14) of another blade (12) farther downstream in the wind tunnel (20). Thus, after the wind-receiving surface (14) of this other blade (12) has received the strongest wind, at the point when the rotation of this blade has gradually weakened, the blade again receives the wind that has passed through the ventilation holes (1), which imparts a stronger rotational force, so that the rotational force can be increased even at that position.
