Africa-Press – South-Sudan. <\/strong><\/span>Researchers have discovered a new material similar in structure to that of an owl’s wings that can potentially reduce the noise generated by wind turbines.<\/p>\n

A new material mimicking the structure of owls’ famously quiet wings could be used to make wind turbines considerably quieter, researchers at Cambridge University and three US institutions found.<\/p>\n

The researchers found that the new material can lower the noise of a wind turbine by as much as 10 decibels (dB) in tests. According to GE Reports, a wind turbine at its source can be as loud as 105 dB, or as much as a gasoline-powered lawnmower. The new material would make a wind turbine with the material slightly louder than a blender.<\/p>\n

The noise reduction also allows for the generation “several additional megawatts worth of electricity” when applied to an entire wind farm, according to the press release.<\/p>\n

“Much of the noise caused by a wing \u2013 whether it\u2019s attached to a bird, a plane or a fan \u2013 originates at the trailing edge where the air passing over the wing surface is turbulent. The structure of an owl\u2019s wing serves to reduce noise by smoothing the passage of air as it passes over the wing \u2013 scattering the sound so their prey can\u2019t hear them coming,” lead researcher Nigel Peake said.<\/p>\n

The researchers used 3D printing to create the structure similar to owl feathers. The new design allows the turbines to spin around much more quietly by “scattering” the sound in the same way an owl’s wing does.<\/p>\n

“While we\u2019ve known this for centuries, what hasn\u2019t been known is how or why owls are able to fly in silence,” Peake added.<\/p>\n

Researchers also aim to conduct the test on an actual wind turbine and eventually test the new material on airplanes.<\/p>\n
