The first thing people ask when they see a Thinair turbine is "why does it have only one blade?" The answer to that question is the key to understanding the unique benefits that Thinair's innovative and patented single blade teetering hub design offers. Traditionally, wind turbines are constructed with multiple blades, attached to a fixed hub. The Thinair turbine, by contrast, has a freely teetering hub design that allows the blade's angle to change in response to variations in wind speed. As a result the Thinair makes efficient use of strong and gusty wind; it harnesses gusty wind to generate extra energy. The teetering hub also protects the turbine from damaging stress, allowing the blade to swing into a safe horizontal park position in e...

Windflow Technology Ltd

Windflow Technology Ltd was incorporated in 2000 and is a public company with international shareholders that is currently listed on the New Zealand Exchange's alternative market, the NZAX. It was formed to provide a local manufacturing option and wind power engineering services to the nascent wind industry in New Zealand and Australia. Windflow is focused on global expansion and ongoing design innovation, and represents an opportunity to invest in our energy future.

Business type: manufacturer
Product types: The Windflow 500 is a 500 kW 33 m two bladed horizontal-axis wind turbine. It is the first wind turbine to combine two new technologies, the patented torque limiting gearbox (TLG) system of power control and the pitch regulated two-bladed teetering rotor. The combination of the TLG system and the two bladed rotor design effect major reductions in fatigue loads. The Windflow 500 design results in weight and cost reductions of between 20-50% compared to currently available commercial windmills of similar power rating. The end result combines cost-effectiveness, simplicity and reliability in a world leading design. .
