LM Wind Power Announces 73.5 m Turbine Blade

Wind Energy

This new blade will be the longest composite blade structure in the world at 73.5 meters creating an impressive swept area with a rotor diameter of 150 meters.

The LM 73.5P wind turbine blades will be installed on Alstom’s 6 MW wind turbines offshore, mainly in European waters, where the giant blades will travel at the speed of more than 320 km/h in order to generate green power equivalent to the yearly requirements of over 6000 European households

Vice President, Product Development at LM Wind Power, Jan Kristiansen is looking forward to being able to present the first prototype blade in Denmark already at the end of this year. “The size of these impressive structures has more than doubled over the past decade alone, and although this has of course demanded the development of new materials, design and technology along the way, the new 73.5 meter blade is built on our progressive accumulation of know-how. This ensures that even though it is more than ten meters longer than our recent world record blade, it is still based on a proven concept.”

The company says it is in discussions with a number of Asian wind turbine manufacturers about making blades longer than 80 m.
