A flexible, controllable trailing edge for wind turbine blades has shown that it can reduce the loads on the turbine and in the end provide cheaper electricity from wind power. The idea dates back ...

”Providing the blade with a movable trailing edge it is possible to control the load on the blade and extend the life time of the wind turbine components. This is similar to the technique used ...

A flexible, controllable trailing edge for wind turbine blades has shown that it can reduce the loads on the turbine and in the end provide cheaper electricity from wind power.

If you’ve ever seen a commercial-scale wind turbine in real life, then you’ll know that they’re huge – a single blade can be as long as 60 meters (197 feet). Researchers from Denmark’s ...

Aeroelastic stability of rotating blade is indicated by Floquet Theory, and the stability indications show good agreement with results of open-loop simulation test for critical flutter speed study. It ...

The wind energy start-up, evoblade, a spin-off of the Institute of Aerospace Technology (IAT) of the University of Applied Sciences Bremen (Germany), has developed a composite retrofittable trailing ...

To mimic this effect on a wind turbine blade, they designed a set ribs, or “finlets” that would sit in front of the blade’s trailing edge and manufactured them with 3-D printing technology.

The combed-teeth structure of Siemens’ new low-noise DinoTail aerodynamic blade add-on mimics an owl wing’s trailing edge fringe. For comparison, an un-combed blade is shown on the left ...

To address these concerns, Sany developed an optimized aerodynamic design for the SY1310A wind turbine blade, featuring a large thickness and blunt trailing edge.

It is also quieter – according to New Scientist, “when air flows from above and below the trailing edge of a turbine blade meet, they create turbulence, which can increase drag and make it noisy.

Chinese wind turbine manufacturer Sany Renewable Energy has unveiled the world’s longest onshore wind turbine blade, a 131-metre behemoth to be used on the company’s 15MW turbines.
