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 to ...

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 ...

A joint research project carried out by Wärtsilä and City University London has succeeded in identifying the specific design parameters that create the risk of 'singing' propellers. Though rare, ...

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 Risoe DTU ...

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 using ...

French electric marine drive specialist BlueNav is preparing to put a more natural spin in its lineup. The all-new Whale Design propeller features blades that follow the contours of a whale to improve ...
