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 ...

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 ...

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 ...

Risoe National Laboratory for Sustainable Energy, the Technical University of Denmark The idea dates back to 2003 when researchers from Risø DTU was inspired by the prey's ability to maneuver in ...

ABSTRACT A mathematic rotating blade model is introduced in conjunction with periodic time-varying aerodynamic load, which is described by Beddoes-Leishman dynamic stall model. The consequent ...

Wing flaps are movable surfaces located on the trailing edge of the wings and are typically deployed during specific phases of takeoff and landing. The majority of planes have these, whether jets or ...

NASA’s green aviation project is one step closer to developing technology that could make future airliners quieter and more fuel-efficient with the successful flight test of a wing surface that can ...

Boeing plans to test and develop a trailing-edge variable camber (TEVC) system for the 787, which it says will reduce cruise drag and save the equivalent of 340-450kg (750-1,000lb) in weight. The ...
