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 ...

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 ...

In January, we looked at FlexFoil; a variable geometry airfoil system that seamlessly integrates into the trailing edge of the wing. During the year the system has made the leap from the test bench to ...

The first airplane ever flown, the Wright Flyer, used "wing-warping," in which pulleys twisted the trailing edge of the airfoil for roll control. Ironically, NASA is now revisiting that tech in a way ...

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 ...
