Traction (mécanique)Index. décimale : 620.11 Matériaux (propriétés, résistance) Résumé : More competitive design is required for wind turbine blades to be lighter, stiffer and more durable. To increase energy generation, the blades should be larger since wind power is squarely proportional to the blade size. However, this dramatically increases the mass, resulting in more severe conditions. Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=17332

Rotor blades up to 128 m in diameter for wind turbines with power ratings up to 2.5-6.15 MW are already available in the market, and are expected to grow more in future thanks to the development of innovative blade designs.

Pales d'éoliennesIndex. décimale : 668.4 Plastiques, vinyles Résumé : New design and material solutions are proposed for larger-scaled wind turbine blades as a highly effective way of reducing the cost of energy. The innovative blade design uses an asymmetrical skin and spar cap, which are proven to be very effective, reducing total materials and costs especially for ultra-large wind turbines blades. The new design tool was developed combining FAST by NREL and customized HyBlade and MMFatigue modules for a multiscale approach. In this article, four design cases are studied to demonstrate the new solution. C-PLY non-crimp fabrics (NCF) from Chomarat are now available in the market to accommodate such unique performance, especially for larger-scaled blades. Note de contenu : - Design studies

Pales d'éoliennesIndex. décimale : 668.4 Plastiques, vinyles Résumé : JEC Composites Magazine discussed with Wolfram Axthelm Bundesverband WindEnergie e.V. (BWE), what is to be expected when the funding period of the German Renewable Energy Act [EEG) runs out in 2020. At this time, fewer and fewer wind energy systems are expected to be resold and reconstructed in other places due to increasing worldwide standards and the higher yields of more modern systems. Therefore, recycling is increasingly becoming an issue. In particular, the environmentally friendly recycling of rotor blades, mainly consistling of composite materials particularly CFRP, is raising issues and is challenging researchers.

Pales d'éoliennesIndex. décimale : 668.4 Plastiques, vinyles Résumé : As they are getting increasingly longer, wind turbine blades need to be stiffer and lighter to avoid cracks from fatigue loading and to help lower foundation construction costs. Current development processes are mainly 2D-based and rely on heterogeneous suites of tools that are not compatible with the quality and stiffness requirements of designing larger blades. Moreover, these tools do not allow to take last-minute engineering changes into account for manufacturing instructions.. In this context, wind turbine manufacturers are looking for innovative development solutions – particularly for blade architecture, design, simulation and manufacturing – that will help them meet these requirements while achieving longer life spans without defects.
