Enercon has installed two ABB robots in its new paint facilities in Aurich for painting rotor blades. This is the first installation of its kind, able to complete the entire finishing process on large dimension rotor components. Finishing consists of two layers: The first layer is the gel coat. . The ABB robots provides the exact amount of gel coat for the required thickness: Depending on the amount of stress on a particular area, thicknesses may vary between 0.3 mm where loads are light and 0.6 mm along the leading edge or so-called nose (part of blade in first contact with wind) where loads are particularly high. The second layer is an environmentally friendly water-based varnish. Colour schemes ranging from plain grey to diagonal red-white-red-grey stripes are fully automatically coordinated without having to stop the facility in-between. Paint and finishing robots require extremely sophisticated control systems. An even coat can only be obtained with smooth-flowing motions. This is achieved by using seven axis paint robots. The electronic control system not only coordinates the robots seven axes but at the same time monitors all the other technical parameters such as temperature, viscosity, spray pressure and the correct paint dosage, explains Torsten Link, ENERCONs expert for blade finishing. Enercon manufacture the world’s largest turbine blades with rotor diameters of over 125 meters. The paint protects the blades against the weather conditions which they are …

This video shows the use of a genetic algorithm to develop VAWT wind turbine blades. One of the resulting blades is quite different and seems to simulate well. The breeding software was written in Perl, the display software Java, and the CFD software was openfoam. More than 672 CPU hours went into the making of this video.

I purchased a set of windmax Blades to test for one of my projects. Overall they were great looking, performed very well and were cost effective. In this video I take wind measurements and rpm readings from the front of the turbine blades . I had to do some extra balancing to make these blades vibration free, but well worth the time.
