DYNAMICS OF VERTICAL AXIS WIND TURBINE

摘要

The present invention includes a vertical axis wind turbine with isolator mechanism for eliminating dynamic instability caused by uneven forces. The isolating mechanism includes of a plurality of rotating isolators/vertical support, plurality of tethering devices, plurality of pair of horizontal members, plurality of pair of clamping devices. The rotating isolators are arranged close proximity to the central fixed shaft of the turbine. The plurality of clamping devices arranged around the rotating isolators and each clamping device attached with vertical blades via a tethering device, and each clamping device attached with each clamping device via horizontal members. Wherein, when the uneven wind force act on the turbine then the isolator mechanism diverts the vibration via itself to tower and thereby dynamic instability is eliminated.
