The longest wind turbine blade in the world is developed by Danish LM Wind Power and has a length og almost 90 meters. It is so solid that it can withstand the weight on ten full-grown elephants without breaking, and has a maximum speed by the blade tip of 300 km/h.
LM Wind Power and Adwen have partnered to take a large step forward towards lowering the cost of energy in offshore, putting their respective technology expertise together to present the longest blade in the world.
The huge component of 88.4 meters has been specifically designed for Adwen’s AD 8-180 wind turbine model, with 8MW nominal capacity and 180 meters rotor diameter. The first of these huge blades has just been manufactured at LM Wind Power’s factory in Lunderskov (Denmark) and will be transported to a facility in Aalborg in the following days, where it will commence rigorous testing in the framework of Adwen’s extensive product validation plan.

The engineering teams of both companies have been working together for months to design and integrate a blade that represents an important step forward in the race to lower the Levelized Cost of Energy (LCoE). With the largest rotor in the industry (180 meters), the AD 8-180 has the highest annual energy production (AEP) of all wind turbines.
The 88.4 meters length of the blades is the best compromise between swept area, energy production, and the weight as well as the loads transferred to the wind turbine. This combination provides the optimum balance of plant costs and contributes to one of the most competitive LCoE in the industry. In addition, the blade design has been conceived with scalability in mind to enable the further development of Adwen’s 8 MW platform.

-The LM 88.4 P blade is an extraordinary example of industrialised innovation at record breaking scale. It is based on innovation building blocks, rooted in 35 years of real life experience, in the design, technology and manufacturing of ultra-long, reliable blades. This blade is a strong proof point of the shared ambition of Adwen and LM Wind Power to bring forward best in class and proven rotor solutions for offshore application, increasing Annual Energy output through efficient and reliable technology, says LM Wind Power’s CEO, Marc de Jong.
