Wind Harvester Models 1.0 and 2.0 Prototype

Wind Harvest had never tested a three-bladed configuration. There was concern that the longer distance between each blade in the rotor’s circumference would create a problematic “torque ripple” in the energy output. Model 1.0 used the same blade configuration as the 530G with 12 blades essentially placed 30 degrees apart from each other. This smoothed out the torque but the 24 arms and blade ends created significant drag. Model 2.0 used the same 12 blades but aligned them so that there were only 6 exposed blade ends and 12 arms. The good news was that 2.0 did not produce any significant torque ripple that harmed power quality and was more efficient at producing energy.
