Title:
BLADE STRUCTURE AND POWER GENERATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2015/034096
Kind Code:
A1
Abstract:
This blade structure (2) includes: a plurality of blades (22) that receive a flow force, which is the force of a fluid; a support member that supports the blades (22) and can rotate around a rotation shaft extending in a direction perpendicular to the flow force; and a blade rotating mechanism that freely rotates the blades (22) around the rotation shaft by an amount corresponding to a prescribed rotation angle (TZ). Thus, the flow force can be used to incline the blades in the flow force direction so as to disrupt the symmetry of the blades, and the drag generated at the blades can be increased. Therefore, it is possible to increase the torque of the blade structure (2).
