Aircraft noiselessness will be provided by new wings like owls

In a new study, a team of scientists collected detailed 3D data on owl feathers.

 The results show that in the wings of owlsThere are nanofeathers that work almost like fins: they can control the flow of air near the aerodynamic wall and hold it longer and with greater stability, avoiding turbulence.

Scientists have transferred all data on nanofeathers todigital model and studied their aerodynamic properties under various conditions. The results of the work confirmed that these small protrusions perform a serious aerodynamic function: they control air flow according to its direction and use it with maximum efficiency for flight.

Thanks to this, the birds' flow around the wing with a swept profile is stabilized: this usually happens when the bird soars. 

The team plans to use their knowledge to design aircraft. Their developments will help to use wind energy more efficiently and reduce flight noise.
