The Axowind vertical axis wind turbine was designed developed in Sydney, Australia by mechanical and aeronautical engineers.
It’s unique shape is based on aerodynamic and structural principles to maximise power and minimise noise.
Vertical axis wind turbines are inherently low noise. Noise is generated by tip speed. The large blade area at maximum diameter generates high torque at a lower speed than conventional horizontal axis wind turbines.
A problem with many vertical axis wind turbines is that they are very inefficient compared to horizontal axis designs. The Axowind design is highly optimised with minimal structural drag and an efficient blade design.
