Gamesa 56 Meter Blade Testing

We completed static strength testing of a 56-meter (184-foot) wind turbine blade for Gamesa, a global technological leader in the wind industry, based in Spain. Juan Diego Díaz, 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.
