6 FAQs about [The feathers of wind power]

Can owl feathers be used in wind turbines?

The key to the puzzle lies in the intricate structure of owls’ feathers – and especially the plumage on the trailing edge of their wings. The researchers have now been able to replicate this structure by producing a prototype surface (patented in 2014) which has potential applications in wind turbines and a wide range of fans.

Can a wind turbine cover a owl's wing structure?

What they found led them to develop a prototype coating that mimics the owl’s wing structure. By covering a wind turbine blade with a material similar to a wedding veil, the team was able to reduce surface noise by up to 30 decibels during initial tests.

Could a silent flight of Owls reduce wind turbine noise?

The silent flight of owls is the inspiration behind a research project that aims to reduce the noise of wind turbine blades without affecting aerodynamics. But how could this benefit wind farm operators, and what’s the next step? The wind power market has grown at a CAGR of 14% between 2010 and 2021 to reach 830 GW by end of 2021.

How does a wind turbine work?

That reduction of noise and turbulence behind the blade allows the turbine to spin slightly faster in wind of the same speed, generating more power. Biome Renewables also turned to whirling maple seeds for inspiration. Spinning blades create suction that pulls air into the middle area where the blades meet.

Can a wind turbine wing reduce noise?

By covering a wind turbine blade with a material similar to a wedding veil, the team was able to reduce surface noise by up to 30 decibels during initial tests. "The structure of an owl’s wing serves to reduce noise by smoothing the passage of air as it passes over the wing, scattering the sound."

Could a new coating make wind turbines quieter?

A newly-designed material, which mimics the wing structure of owls, could help make wind turbines, computer fans and even planes much quieter. Early wind tunnel tests of the coating have shown a substantial reduction in noise without any noticeable effect on aerodynamics.
