A vertical-axis wind turbine (VAWT) is a type of wind turbine where the main rotor shaft is set transverse to the wind while the main components are located at the base of the turbine. This arrangement allows the generator and gearbox to be located close to the ground, facilitating service and repair. VAWTs do not need to be pointed into the wind, which removes the need for wind-sensing and orie…
GRTC stated the new Golden Spiral VAWT design conforms to its patented extended spiral leverage arm technology that increases torque. The design is based on Golden Ratio geometry and …
Vertical axis wind turbine performance. The shapes of VAWT blades vary from the scoop shaped blades designed for the low tip speed ratio (TSR) VAWTs to profiled blades of Darrieus type VAWTs with airfoil-like cross sections for high TSR designs. Regarding the arrangement of blades along the axis of rotation they can be straight, …
