Rotor blades account for about one quarter of the total cost of a wind energy turbine, a fact which results from the high proportion of manual labour involved. Significant cost reductions can be achieved through changing from small series production to large scale industrial production.
For this reason, the main focus of the joint project “BladeMaker“, with a total of 18 partners and coordinated by the Fraunhofer IWES, is the complete manufacturing chain for rotor blade production.
The project’s target is to reduce production costs by well over 10 per cent and for the long term, to set up a “BladeMaker Demo-Centre” which will be a national and international centre for the research and development of rotor blade production. In order to achieve this ambitious target rotor blade design, materials and manufacturing processes will be taken into consideration. Florian Sayer of the Fraunhofer IWES explains:”In international competition rotor blade producers are under great cost pressures which we will tackle with automation.”
The researchers at the Fraunhofer Institute will first of all analyze all of the work procedures and technologies of rotor blade production and assess automation potentials. Then, any promising automated manufacturing processes will be investigated and simulated. Finally, at the end of the five year project demonstrators will be created for the respective process steps and the “BladeMaker Blade” will be designed, optimized for automated production. “The BladeMaker design provides an insight into what can be achieved in automation,” explains Sayer about the project.
The BladeMaker project will run until the end of September 2017. The project is funded with EUR 8 million by the German Federal Ministry for the Environment, Nature Conservation and Reactor Safety.
Background rotor blade production:
The state of the art in rotor blade production is the so called vacuum infusion process. For this purpose, two moulds or blade halves are reinforced with fibre-glass or carbonfibre matting. This work step is undertaken almost completely manually. Then a vacuum is generated and a resin injected bonds the mats. After hardening, the two halves are pieced together to form one blade and then varnished.

Siemens scientists have developed new kinds of ceramics in which they can embed transformers.
The new development allows power supply transformers to be reduced to one fifth of their current size so that the normally separate switched-mode power supply units of light-emitting diodes can be integrated into the module's heat sink.
The new technology was developed in cooperation with industrial and research partners who ...
Cheaper clean-energy technologies could be made possible thanks to a new discovery.
Led by Raymond Schaak, a professor of chemistry at Penn State University, research team members have found that an important chemical reaction that generates hydrogen from water is effectively triggered -- or catalyzed -- by a nanoparticle composed of nickel and phosphorus, two inexpensive elements that are abundant on Earth. ...

It's not reruns of "The Jetsons", but researchers working at the National Institute of Standards and Technology (NIST) have developed a new microscopy technique that uses a process similar to how an old tube television produces a picture—cathodoluminescence—to image nanoscale features.
Combining the best features of optical and scanning electron microscopy, the fast, versatile, and high-resolution technique allows scientists to view surface and subsurface features potentially as small as 10 nanometers in size.
The new microscopy technique, described in the journal AIP Advances,* uses a beam of electrons to excite a specially ...
