Title:
STRUCTURE THAT UTILIZES HYDRODYNAMIC FORCES
Document Type and Number:
WIPO Patent Application WO/2013/069757
Kind Code:
A1
Abstract:
Provided is a structure that utilizes hydrodynamic forces that is capable of responding to wind velocities and flow velocities in a broad design range by means of a simple structure, without needing any adjustments according to wind orientation and flow orientation, and that uses lift-type blades that do not require a crane ship, even for work ranging from delivery to, installation at, and removal from an installation site, for wind turbines and waterwheels on water. A vertical axis wind turbine (100) is provided with an upper strut (40), which extends vertically and is capable of rotating around a vertical shaft, and blades (60) that receive wind power. The blades (60) are in proximity to or separated from the upper strut (40), and the radius of rotation (r) of the blades (60) is adjusted.
