Clarion Energy Content Directors 5.1.2018 Share By Editors of Power Engineering The National Renewable Energy Laboratory released a video demonstrating its wind turbine blade testing capabilities. The facility conducts structural research with servo-hydraulic equipment and data acquisition systems to ensure blades live up to the International Electrotechnical Commission 61400-23 standard. The facility can validate blades and other components as small as one meter to more than 50 meters in length. NREL can evaluate structural properties such as shape, mass and inertial and stiffness properties. The facility can measure static strength by applying quasi-static bending movements to validate design parameters, including extreme loads applied by cranes, hydraulic actuators and servo-electric winches. Additionally, the facility conducts fatigue research by applying millions of cycles of fatigue loads either single-axis by direct load application or biaxial loading with flapwise and lead-lag directions simultaneously.
