Industrial Production instead of Rotor Blade Manufactory - Fraunhofer IWES starts new project

15.01.2013
Rotor blades are still made almost completely by hand. In the “BladeMaker“ project, Fraunhofer IWES scientists and industrial and research partners are searching for automation solutions in order to make the manufacture of rotor blades more cost effective, quicker and with a higher quality.

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.

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...

Im Focus: How to inflate a hardened concrete shell with a weight of 80 t

At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).

Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...

Im Focus: Bacterial Pac Man molecule snaps at sugar

Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.

The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...

Im Focus: Repairing defects in fiber-reinforced plastics more efficiently

Fiber-reinforced plastics (FRP) are frequently used in the aeronautic and automobile industry. However, the repair of workpieces made of these composite materials is often less profitable than exchanging the part. In order to increase the lifetime of FRP parts and to make them more eco-efficient, the Laser Zentrum Hannover e.V. (LZH) and the Apodius GmbH want to combine a new measuring device for fiber layer orientation with an innovative laser-based repair process.

Defects in FRP pieces may be production or operation-related. Whether or not repair is cost-effective depends on the geometry of the defective area, the tools...
