Title: BLADE MEMBER FOR WIND POWER GENERATION
Abstract:
A blade member for wind generation is provided which can effectively suppress said blade tip vortex effects in a region in which blade tip vortex effects are great by means of a rectifier plate, and which simplifies the configuration by reducing or omitting the rectifier plate in regions in which blade tip vortex effects are relatively minor. This blade member (60) is provided with a blade main body (70) which extends in the vertical direction along the direction of the rotary shaft, and a rectifier plate (90) which is arranged at the upper end and/or the lower end of the blade body (70). The rectifier plate (90) is arranged so as to project from the blade main body (70) both towards the rotary shaft and away from the rotary shaft, and is configured such that the inwardly arranged part (92), which projects from the blade main body (70) towards the rotary shaft, has a greater maximum width than the outwardly arranged part (94), which projects from the blade main body (70) away from the rotary shaft.
