Flexible trailing edge flap for blades to make wind power cheaper

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 2003 when researchers from Risø DTU was inspired by the prey's ability to maneuver in turbulent air currents, while they at the same time remained at a stable point in the air. Now a three-year project co-funded by EUDP (the Danish Programme for Energy Technology Development and Demonstration), with three industry partners, is launched and is to develop the promising technology forward to a robust and durable trailing edge which can be tested on a full-scale blade.
