Owls' wings could hold the key to beating wind turbine noise
July 4, 2017


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.

Noise is only 1 complaint.

Sounds like a lot of people have issues with the oscillating pressure of the blades moving through the air.

I seriously doubt that. An owl's wings do not move the same huge masses of air that a windmill does. The only way one of those will ever be silent is if it is offline, as most are 70% of the time.
