maximize aerodynamics in design of porous airfoils (2-D wings) to improve wind turbines and air vehicles. Many species of owl are able to hunt without being heard by their prey by suppressing the ...

The team has succeeded - through physical experiments and theoretical modelling - in using the downy canopy of owl feathers as a model to inspire the design of a 3D printed, wing attachment that ...

Many species of owl are able to hunt without being heard by their prey by suppressing the noise of their wings at sound frequencies above 1.6 kilohertz (kHz) -- including the range at which human ...

Now, the team has succeeded - through physical experiments and theoretical modeling - in using the downy canopy of owl feathers as a model to inspire the design of a 3-D printed, wing attachment ...

The serrated edge of owl wings, which help the birds swoop down ... exactly how these could cut noise, and whether these design changes produce universal effects, remained to be seen.

Owl wing design reduces aircraft, wind turbine noise pollution. ScienceDaily . Retrieved June 2, 2025 from www.sciencedaily.com / releases / 2022 / 01 / 220118111351.htm ...

Researchers at the University of Cambridge have reverse-engineered the design of the owl’s silent wings and applied it to wind turbines, allowing them to cut through the air more quietly ...

and whether these design changes produce universal effects, remained to be seen. In the new study, researchers from Xi’an Jiaotong University in China used noise calculation and analysis software to ...
