Title:
WIND/WATER FORCE VANE WHEEL BY REVERSING BLADE
Document Type and Number:
Japanese Patent JP2001227451
Kind Code:
A
Abstract:
To develop a device to be used for power generation by rotating a small-sized or ultra-large-sized vane wheel by efficiently utilizing both of lift and drag generated in the vane wheel by wind force/water flow force/wave force.
The problem is solved by unnecessitating a directional control by the vane wheel in which reversing blades 1 capable of freely rotating by a fixed angle are arranged on a cylindrical surface or a horizontal disc and by efficiently converting not only lift but also drag to be just a negative factor in a propeller-type windmill into rotational force.
