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

Date:
    July 4, 2017

Summary:
    Inspiration from owls' wings could allow aircraft and wind turbines to become quieter, suggests a new study. Researchers 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 point towards potential mechanisms for noise suppression in wind turbines, aircraft, multi-rotor drones and other machines.

Bigass difference in the velocities owls flap their wings and the rotational speed of a gas turbine. I seriously doubt a certain base level of noise can ever be overcome.

The subject is wind turbines and aircraft wings, not jet engines.

Allowing wind turbines to kill more birds.  Winning!

Birds? They can start killing mice and voles now, too.
