The shape of the helix was inspired by nature (Bionics) and resembles the human DNA structure. The spiral structure of the helix design ensures that even during turbulence, the wind can have an effect on every part of the surface area. The action is based both on aerodynamic lift as well as resistance induced tunneling.Ī vertical axis turbine (VAWT: Vertical Axis Wind Turbine) functions regardless of the wind direction. The blades are arranged offset from one another, so that a part of the wind is diverted from the right and left openings to the scooped sides of the blades and can therefore act on the reverse side of one of the concave blades. Ultra-lightweight rotor made from modern high-performance composites, consisting of two horizontal lens discs, attached to a vertical rotor axis, between which two or more semicircular curved blades are vertically mounted. The wind turbine Wind of Change with its characteristic helical shape has an increase in output of more than 28 percent in complex 3D aerospace engineering flow analysis tests, when compared with conventional vertical resistance runners.

The new wind turbine follows the classic Savonius idea, but has a new innovative rotor geometry, which thanks to an intelligent flow design, avoids pressure differences, outages and turbulence.

Innovative Technology – Tried and Tested!Įxtensive wind tunnel tests and numerical flow calculations were used to develop and optimize an ultra-lightweight slow speed vertical small wind turbine system, using the highest possible levels of efficiency and based on the Savonius rotor.įor months, we developed, calculated and optimized this innovative rotor form which enables a higher yield of the oncoming wind.
