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 ...

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 ...

As the angle of attack is increased on a high-performance airfoil, a small amount of separation occurs near the leading edge. This separation causes the boundary layer to transition from laminar to ...

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 ...

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 ...

Illustration of the airflow along an airfoil that exhibits leading-edge stall behavior. Notice the formation of a “short bubble” at a critical point along the leading edge. When the AOA is increased ...
