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 ...

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 ...

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 ...

Question: If flaps don’t increase lift, then why is a small amount of flaps used in soft-field takeoffs for some aircraft? Answer: Who said flaps don’t increase lift? Flaps do increase lift. Reference ...

ANN ARBOR (WWJ) --An Ann Arbor company is giving the aviation industry its long-sought, elusive goal of practical seamless control surface technologies. A variable geometry airfoil, called FlexFoil, ...

The Fowler flap was invented around 1920 by one Harlan Davey Fowler, an engineer who was then in the employ of the U.S. Army. An internet search for his name turns up, in addition to various ...

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 ...

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 ...
