Turbine blade flies 60 meters through air

According to the wind turbine manufacturer, a lightning strike could have been the reason why the rotor blade broke loose.

The rotor blade of a wind turbine in Nortorf (Steinburg district) broke off on Thursday and flew 60 meters through the air. This was announced by wind turbine manufacturer Amperax on Friday. The blade is one of three rotor blades of a 150 meter high wind turbine with a rotor diameter of 116 meters. It flew over a promenade and landed in a meadow. No one was injured, according to Amperax. 

Four men stood around the broken rotor blade of a wind turbine as it lay on the grass of a meadow.

The cause of the blade failure is still under investigation. 

According to the wind turbine manufacturer, a lightning strike could have been the reason why the rotor blade broke loose. The State Department for Agriculture, Environment and Rural Areas (LLUR) is also looking into the situation according to one spokesman. Three nearly identical systems were stopped on Thursday and would now be reviewed, a spokesman for the company said. However, no deficiencies were found in them.

(editor's note: Since this piece was posted, additional reporting suggests the blade was thrown 75 meters)
