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 ...

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 trailing edge of wind turbine blades can be manufactured in an elastic material that makes it possible to control the shape of the trailing edge. This will reduce the considerably dynamic loads ...

Aircraft morphing, especially in the case of the variable camber airfoil, has potential from the viewpoints of both fundamental aerodynamics and flight application. In the field of aerodynamics, the ...

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 ...

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 ...
