Bends, Twists, and Flat Edges Change the Game for Wind Energy

Wind turbine blades naturally bend when pushed by strong winds, but high gusts that bow blades excessively and wind turbulence that flexes blades back and forth reduce their life span. Bend-twist-coupled blades twist as they bend. As wind forces the blade to flex, twisting changes the blade''s angle of attack (the angle at which the blade

How to use eologix-Ping sensor systems for your wind turbine

With the eologix-Ping sensor systems you can keep an eye on the condition and operation of your turbine. Our sensors enable spot measurements directly on the rotor blade surface as well as acoustic measurements inside the rotor blade or on the tower of the turbine. They can also be used for any wind turbine, anywhere and in any life cycle.
