Independently developed the longest wind turbine blade offline

Recently, a set of 1?5 MW wind turbine blades with a length of 40.25 meters was successfully approved for sale at Sinoma Technology Wind Power Blade Co., Ltd. This is the longest wind power blade independently developed by China and shows that China has the capability of independent development and manufacturing of large megawatt blades.
According to reports, Sinoma Technology Wind Power Blade Co., Ltd. was established in June 2007 by Sinoma Science and Technology Co., Ltd. as the main sponsor. The company has inherited the technology and experience of research and development of composite materials products of Beijing FRP Research and Design Institute for nearly 50 years. It is a high-tech enterprise specializing in the research, design, manufacture, sales, and technical service of wind power blades and their molds.
The set of wind turbine blades that have been offline this time is a well-known blade design company outside the United Nations, which uses its accumulated 37.5-meter blade design experience for many years to design optimization and improvements. This product is specially designed for China's low wind speed wind conditions, adopts the international mainstream vacuum-assisted infusion molding process and more advanced aerodynamic shape design, based on localization, high-performance, reinforced material development and design, with independent intellectual property rights. This product has the advantages of low unit load, large swept area and high power generation efficiency compared to other 1?5 MW grade products.
Through technology research on blade load calculation, advanced airfoil design, and blade industrialization manufacturing technology, the company has broken through common key technologies such as mold manufacturing, large-scale blade industrial manufacturing, and new composite material design and manufacturing, and possesses independent research and development capabilities for large blades. And industrial production of complete sets of technology.
At present, Sinoma Leaf has an annual output of 10 sets of molds and 200 sets of SINOMA40,2 blade production capacity, and 600 pieces of wind power blades can be produced each year. It is understood that the company has signed supply contracts with wind turbine manufacturers such as Sinovel. The wind turbine blades that have been offline have been partially transported to the wind farm in northeast China. In the coming years, the company plans to build a blade production plant in a region with abundant wind energy resources to further expand its production scale. In order to adapt to the development trend of large-scale single-capacity wind power in the world, the company is actively working on the development of 3.0 MW wind turbine blades.
