A new sound-suppression study provides fresh insight for airfoil design and noise control for micro-aircraft and fluid machinery. The research focused on the concept of trailing-edge noise by using ...

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 ...

Aeroacoustics, the study of noise generation via unsteady aerodynamic phenomena, occupies a pivotal role in the evolution of modern airfoil design. Contemporary research explores the interplay between ...

Aircraft wings have changed drastically throughout the years, with efficiency now a key factor in designs.

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 ...

The two contending planes featured in "Battle of the X-Planes" make use of radically different wing designs: one uses a triangular-shaped delta wing; the other, traditional wings. Each design has its ...

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 ...
