Researchers used the characteristics of owl wings to inform airfoil design and significantly reduce trailing-edge noise. The team used noise calculation and analysis software to conduct a series of ...

The serrated edge of owl wings, which help the birds swoop down stealthily on unsuspecting prey, can help inform better designs that cut noise from aeronautical and turbine engines, according to a new ...

Researchers from Harvard and the University of South Carolina have developed a new kind of airfoil, inspired by shark skin, that may improve lift in aircrafts. Mehdi Saadat, an Organismic and ...

Natural laminar flow is a known means of reducing aircraft drag and energy consumption, but its practical implementation is difficult on commercial airliners that cruise at transonic speeds and ...

WASHINGTON, January 18, 2022 -- Trailing-edge noise is the dominant source of sound from aeronautical and turbine engines like those in airplanes, drones, and wind turbines. Suppressing this noise ...
