Owls' wings could hold the key to beating wind turbine noise

20:00 EDT 2 Jul 2017 | AAAS

(IOP Publishing) A new study has revealed how inspiration from owls' wings could allow aircraft and wind turbines to become quieter. Researchers from Japan and China studied the serrations in the leading edge of owls' wings, gaining new insight into how they work to make the birds' flight silent. Their results, published today in the journal Bioinspiration and Biomimetics, point towards potential mechanisms for noise suppression in wind turbines, aircraft, multi-rotor drones and other machines.
