BLADE FOR IMPELLER WHEEL FOR WIND TURBINE DEVICE, AND IMPELLER WHEEL FOR WIND TURBINE DEVICE

WIPO Patent Application WO/2012/150691

A1

Two or more blades (30) are provided to an impeller wheel (3) for a wind turbine device (1) in such a manner that the blades (3) are disposed about the rotating shaft (2) so that the blades (3) rotate in a given rotation direction about the rotating shaft (2) when subjected to a wind force acting in the direction of the axis of the rotating shaft (2). Each of the blades (30) is provided with: a blade body (30T) extending outward radially relative to the rotating shaft (2); and a blade tip (30S) extending from the outer side of the blade body (30T) and shaped in such a manner that the blade tip (30S) is bent in the direction opposite the specific rotation direction. As a result of the configuration, the blades provided to the impeller wheel for a wind turbine device generate reduced noise during rotation, improve the rotational performance, and, in addition to such improvements in functions, are excellent in design.
