The inventors at Festo have developed an extraordinary technology platform that uses two pairs of horizontally arranged carbon fibre wings instead of rotor blades to generate power. The principle consists of reversing the natural wing-beating principle: birds generate the necessary power to move forwards in the air by flapping their wings.
A stationary system like the DualWingGenerator, on the other hand, can take the kinetic energy from the flow of air. The wings’ lifting movement is converted here into a rotary movement. An integrated electric motor turns this into electricity.
The DualWingGenerator is self-optimising and can adapt itself to different wind conditions. In terms of its efficiency, it is by no means inferior to conventional small wind power stations and features amazing benefits even at low wind speeds: In the range between 4 and 8 m/s, meaning at prevailing wind speeds in Central Europe at ground level, the DualWingGenerator reveals remarkable outputs compared to conventional small wind power stations.
