Feasibility Assessment of Simultaneous Biaxial Test Methodology by Segmentation Approach for a Supersized Wind Turbine Blade Evaluation

This paper outlines an innovative biaxial segment blade test methodology for large wind turbine rotor blades. Today, as a blade size is getting bigger, not only it is hard to find the test facility incorporating blade over 100 m, but also a blade test time and test cost required for certification according to IEC 6140023 are also increased, which could cause the delay of product entrance to wind energy market. The proposed biaxial segment test method mainly aims at improving the efficiency of the fatigue test because fatigue test takes up more than 70
