초록

A vertical axis wind turbine and vertical axis wind turbine assembly comprising a rotary body and a plurality of blades. A cross section through each blade of the plurality of blades transverse to the rotary axis comprises an inner camber line, an outer camber line, and a chord line. The outer camber line comprises a first portion, a transition portion and a second portion. The second portion is longer, in the lengthwise direction, than a combined length of the first portion and the transition portion. The average second portion thickness is less than ha...
