If you’re historically inclined, you may be interested to know that the first swept-wing airplane appeared in 1907. It was built by J. W. Dunne, a gifted Irishman who also had some interesting ideas ...

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 ...

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 ...

Summary and Key Points: The F-16 SFW (Forward-Swept Wing) was an experimental fighter developed by General Dynamics in the 1970s as part of DARPA’s Forward Swept Wing Program. Designed to reduce drag ...

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 ...

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 ...
