Title:
VARIABLE DIAMETER AND ANGLE VERTICAL AXIS TURBINE
Document Type and Number:
WIPO Patent Application WO/2013/008200
Kind Code:
A4
Abstract:
A wind turbine, particularly vertical axis, whose diameter is extensible and retractable, either from the length of the arms or the angle of the blades, or both, has advantages in operating in low wind speed regimes and surviving in high wind speed, regimes. The current application describes how to construct such a turbine, particularly the control mechanisms and the optimal aerodynamic configurations of the blades.
