Testing of the world’s longest wind turbine blade
The world’s longest rotor blade was manufactured by LM Wind Power in Denmark. Planning the test of the 290 ft (88.4 m) long rotor blade began in 2015. Tests are now underway together with BLAEST (the Blade Test Centre) in Aalborg, Denmark.
The LM 88.4 P test blade arrived at BLAEST on 1st July, 2016, after being transported from LM Wind Power’s Pilot Plant in Lunderskov. Four weeks later, the static test was successfully completed.
The LM 88.4 P demonstrated that it can withstand extremely high winds. In the months ahead, a fatigue test, involving shaking the blade up and down several million times, will establish if they have the durability and longevity to survive 25 years of offshore operation.
Throughout the rest of this year, two LM 88.4 P blades will be tested simultaneously: one at LM Wind Power’s Lunderskov Test Centre, and one at the BLAEST test facility. The parallel testing program will provide results over a 7-month duration – to ensure that the blade fulfils its design requirements in half the time normally required for testing.
