Extension of leading-edge or trailing-edge devices as well as flight controls and spoilers will change the stall development. An airfoil’s stall behavior in turbulent flow and at abrupt pitch ...

Owl wing design reduces aircraft, wind turbine noise pollution Serrated edge of owl wings makes them quieter than other birds, can help inform airfoil designs Date: January 18, 2022 Source ...

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 ...

The trailing edge of wind turbine blades can be ... The size of the protype fits a blade airfoil section with a chord of one metre and such a blade section is now being produced and is going ...

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 ...

Chord of an Airfoil An imaginary line drawn through an airfoil from its leading edge to its trailing edge. Mean Aerodynamic Chord (MAC) Average distance from the leading edge to the trailing edge ...

Slotted flaps predominate today. These consist of a separate airfoil-shaped surface that nests in the trailing edge of the wing and deflects either by traveling along tracks or by pivoting on ...
