The first large-scale wind power CGI90.5A blade using domestic airfoils was prepared in Wuwei, Gansu and successfully rolled off the production line. This type of blade was jointly developed by Jilin Chongtong Chengfei New Materials Co., Ltd. and Northwestern Polytechnical University. The blade length is 90.5 meters, which is currently the largest wind turbine blade on land. It is expected that the rated power will reach 5 megawatts after installation. The blade adopts the airfoil and cascade aerodynamics of Northwestern Polytechnical University. * * The "NPU-MWA-180 multi-megawatt wind turbine airfoil" developed by the China National Key Laboratory of Aeronautics and Astronautics is the first successful application of my country's independent airfoil on the "90-meter" largest wind turbine blade on land.
Wind power is a renewable and clean energy source. In order to achieve the "double carbon" goal, my country has vigorously developed the wind power industry in recent years and has become a major wind power country with the world's largest total installed capacity. Airfoil is the basic element of wind turbine blades and the basis for wind turbine blade design. The development of high-performance airfoils suitable for large wind turbine blades is of great significance for improving the wind energy capture capability of the blades, reducing weight to save manufacturing and transportation costs, and reducing inertial loads and gust loads. However, my country's wind turbine blade design has long relied on the Netherlands, Sweden, etc. * * Not only do you have to pay high royalties for using new airfoils, but you also face a situation where the core technology is controlled by others.
The NPU-MWA multi-megawatt wind turbine airfoil family was independently developed with funding from relevant programs of the Ministry of Science and Technology. It includes 8 airfoils with relative thicknesses ranging from 18% to 60%. It has excellent characteristics such as high design Reynolds number (9 million), high design lift coefficient (greater than 1.2), high lift-to-drag ratio and low roughness sensitivity. The successful application of this airfoil family is an important milestone in my country's independent wind turbine airfoil research. It is also another landmark achievement for the laboratory to give full play to the characteristics and advantages of airfoil research and achieve industry-university-research cooperation. It will help fundamentally get rid of the passive situation of long-term dependence on foreign airfoils and control of core technologies, and ensure the source innovation and leap-forward development of domestically produced wind turbine blades.
