What do shark fins, winglets and turbulators have in common?

By Paul Dvorak This article comes from the Energy Center of the Netherlands
In a challenging experiment, ECN and LM Wind Power have successfully extended blades with an add-on tip extension to test new blade tip designs in the InnoTip research project. With the project now coming to a close, find out how these innovation tip designs could significantly reduce the cost of energy.
‘Shark fins’, ‘winglets’ and ‘turbulators’ all refer to types of tip designs for wind turbine blades—part of an innovative research project called ‘InnoTip.’ The blade tip is the primary source of noise, loads and power output from a wind turbine, so
