en.Wedoany.com Reported - Dimension News, July 22 – CSSC's self-developed 150-meter-class ultra-long flexible smart blade has passed the full-scale static test in Lianyungang, Jiangsu Province. The ultra-long blade adopts a blunt trailing edge airfoil and a dual carbon pultruded girder design, solving the aeroelastic coupling challenge of flexible blades and verifying the structural reliability of the ultra-long blade under severe loads.

As offshore wind turbines enter the era of high power, large-scale ultra-long blades face the technical bottleneck of deep coupling among aerodynamics, structure, and loads. CSSC has shifted its design approach from "independent interaction between the turbine and components" to "strongly coupled integrated penetration design of the turbine and components." The blade has achieved progress in integrated molding of thick carbon fiber girders and modular segmented manufacturing processes, and the integrated intelligent online monitoring system can enhance the turbine's adaptability in complex marine environments.

The ultra-long blade will subsequently undergo fatigue testing, and upon passing, it will be paired with the H305-25MW offshore wind turbine. This turbine was rolled off the production line in December 2025, and under an average annual wind speed of 10 m/s, it can generate over 100 million kWh of electricity per year, reducing project costs by more than 5%. The successful validation of this ultra-long blade provides equipment support for the development of deep-sea offshore wind power.
