Abstract

A vertical axis wind turbine with variable thickness blade is disclosed. The wind turbine may include a blade including a skin having a first skin section and a second skin section. A first skin section thickness may be greater than a second skin section thickness. The blade may further include a bracketed structural member disposed on the first skin section. The bracketed structural member may include one or more L-shaped brackets. The wind turbine may further include a nut bar, which may be a flat nut bar. The bracketed structural member may be configured to hold the nut bar between the L-shaped brackets. The wind turbine may further include an arm connecting bracket that may be configured to attach the arm to the blade via the nut bar. The wind turbine may further include a transition fairing that may attach to the blade via the nut bar.
