The Gamesa blade was the largest tested to date in the UMaine Offshore Wind Laboratory. During the testing, the blade was subjected to loads in four directions to prove the structure met international strength standards.

“We are honored to have served one of the world’s leading wind turbine manufacturers,” said Habib Dagher, director of the UMaine Composites Center. “This is the biggest structure we have tested to date, extending nearly 80 percent of the length of our blade test lab.”

The University of Maine’s facility, which opened in 2011, can provide testing and material characterization services for each stage of blade development. 

Safe testing

 “Our engineers, technicians and students did a great job designing, building and operating the equipment needed to safely rotate and test the 56 m blade,” said John Arimond,  business development executive with the UMaine Composites Center.
