Scientists show a bionic approach combining features of a seagull's wing with an engineered flow control accessory, known as a Gurney flap, can greatly improve wind turbine performance. To achieve the ...

Unless they’ve got stake in a big oil company, the most common reasons people have for opposing the installation of wind turbines is the noise pollution and the risk they pose to birds. But a ...

Windmills offer a great way to harness renewable energy, and they’ve been around for almost two centuries – but who says that’s the only way you can catch the wind? Festo, a supplier of automation ...

For some years, the Wind Energy Division at Risø DTU in Denmark has been working to develop a method for controlling the loads on large wind turbine blades using a flexible trailing edge made of an ...

Researchers attached covert feather-inspired flaps to a 3D-printed model airplane wing and mounted it in a wind tunnel to explore the role of covert feathers in bird flight. By precisely measuring how ...

WASHINGTON, March 22, 2022 -- Wind energy relies on efficient wind turbine blades, which act as airfoils, structures akin to an airplane wing. Air flow control accessories similar to those found in ...
