Wind Blade Testing Team
Wind Blade Testing Client Testimonial
We completed static strength testing of a 56-meter (184-foot) wind turbine blade for Gamesa, a global technological leader in the wind industry which is based in Spain. Juan Diego Díaz, the marketing director for Gamesa, said, “North America was a logical place to conduct this important step in our product development, supporting our growing commercial opportunities in that region and globally. We were impressed by the testing quality, safety and attention to detail provided by the UMaine team in successfully testing our blade.” Image is courtesy of Gamesa.
