The innovative design is based on the aerodynamics of a seagulls wing and utilizes advanced automation control technology for continuous optimization based on wind conditions.
Hauppauge, NY (PRWEB) July 15, 2014
Borrowing from one of the most perfect aerodynamic shapes occurring in nature, a seagulls wing, automation leader Festo has developed a prototype of a small, highly efficient wind powered generator that can be easily mounted on buildings and is effective at low wind speeds.
As measured in wind tunnel tests, the Festo DualWingGenerator is 45 percent efficient at relatively low wind speeds of 9 to 18 miles per hour. To put this into perspective, the theoretical upper limit of efficiency for a wind-powered generator is 59 percent, only 14 percentage points above the DualWingGenerator.
The pilot unit measures a mere eight feet across. Wind flowing over the aerodynamic surfaces causes the two pairs of gull-contoured wings, one pair on each side of the unit, to rise and fall on a central column. This vertical up and down movement is transferred to a rotating belt that turns an electric generator. A Festo CPX automation controller and servo motors continually optimize the angle of each pair of wings for highest overall efficiency based on wind speed and direction.
High efficiency and small size give the DualWingGenerator versatility not found with large wind turbines and wind farms. In the future, roof top units may be used similarly to residential and commercial solar panels to generate building power and to feed electricity to the power grid. The units may also be used to conserve energy by pumping water or compressing air at food, pharmaceutical, or chemical processing plants.
Festo is working on further increases to efficiency. Instead of the rigid wing surfaces, Festo is testing adaptive wings through the Fin Ray Effect®, another process borrowed from nature that mimics the flexible shape shifting of a fishs fin as it moves through water. Utilizing the Fin Ray Effect, the wing surface will change shape depending on the angle of wind flow.
The DualWingGenerator is a Festo Bionic Learning Network project an open, multi-organization program that applies designs found in nature to motivate, inspire, and stimulate innovation.
The DualWingGenerator is an inspirational renewable energy demonstration project and a perfect example of what the Bionic Learning Network is all about, said Frank Langro, Director of Marketing and Product Management for Festo. DualWingGenerator concepts will ripple through research and development efforts and potentially make their effects known in hundreds of different ways.

A video, still images, and additional information can be found on online on the Bionic Learning Network webpages.
