VERTICAL-AXIS WIND TURBINE AND METHOD FOR THE PRODUCTION THEREOF

摘要

The invention relates to a vertical-axis wind turbine and at least 2 turbine blades, wherein every turbine blade is connected via a supporting arm and a connecting element that can be purely tensile-loaded to the rotatable vertical axis. According to the invention, between the connecting element that can be purely tensile-loaded and the supporting arm a blade is provided that is convex at an angle of attack side defined by the turbine blades and is concave at the other side. The invention also relates to a method for manufacturing a wind turbine.
