WTTC opens upsized wind blade test facility
The Wind Technology Testing Center (WTTC, Boston, Mass.) opened its $35 million+ wind blade testing facility on May 18, 2011, the only lab in the U.S. that can test blades up to 90m/295-ft long.

In Europe: Fraunhofer-IWES, NaREC Take Blade testing to 100m/328 ft
Two rotor blade testing facilities in Europe have answered the call for testing capability that will accommodate today’s longer blade designs for offshore wind turbines with newly constructed blade test sites.Fraunhofer-Institut für Windenergie und Energiesystemtechnik (IWES, Bremerhaven, Germany), the first to complete its expanded facility, is now able to test 90m/295-ft blades, up from 70m/230-ft test lengths two years ago.

Upsizing blade test regimes
As composite rotor blade size grows, research groups act to meet the urgent need for physical testing facilities with large-blade capacity.
