Experimental blade research - Phase 2

The objective is to develop the experimental platform needed to design stronger and more reliable wind turbine blades. This will be achieved by developing new test and measuring methods. A design framework that gives guidance on how to choose the appropriate numerical analyses and structural tests needed to obtain the optimal design at a certain level of reliability will also be developed

Project description

The need for more fast and cost effective wind turbine blade design tools has been addressed by several of the major players in the Danish wind power industry. Thus, to meet the demands from the wind turbine manufactures it is necessary to constantly focus on ways to increase profitability and reliability of wind turbines and to realize these ambitions without compromising time and cost. The main objective of the project is to develop an experimental platform which is needed to demonstrate strength and reliability of future optimized wind turbine blades. This requires improved measuring tools and development of a design framework with best-practice recommendations that gives the designer guidance on how to choose the numerical analyses and structural tests needed to obtain a cost-optimal design at a certain level of reliability. The project is managed by Risø DTU, and have the leading wind turbine (blade) manufactures (Vestas, LM-Windpower), subcontractors (SSP-Technology, Hexcel, Baumer), the commercial test facilities (Blaest), DNV, and DONG, as Danish (based) industrial partners in the project. This ensures the technology and knowledge transfer from the project to the wind industry. The German research institute DLR (Deutsche Luft-und Rumfart) and the Swedish research institute Swerea Sicomp are also participants in the project where they will contribute with their comprehensive experience in design and reliability tests which are used in the airplane industry. This will in particular provide the Danish wind industry with a more reliability-based design framework

Results
The objective of this project was to develop the experimental platform needed to obtain better structural design of wind turbine blades. This is achieved by developing new test and measuring methods. It is also achieved by developing numerical and analytical design tools that model the structural behaviour observed in experiments. A design framework that gives guidance on how to choose the appropriate numerical analyses and structural tests needed to obtain the optimal design at a certain level of reliability is also developed. Three blades have been tested to failure and special focus in the project has been
