The largest size of the first land on the land!Western workers have great contributions!

Recently, the first large -scale wind power CGI90.5A blades with domestic wing type were prepared in Wuwei, Gansu, and successfully went offline. This type of blades are developed by Jilin to focus on Chengfei New Materials Co., Ltd. and Northwestern Polytechnical University. The length of the leaves is 90.5 meters. It is currently the largest and magnitude of the wind machine blades on land. Essence This blade uses the "NPU-MWA-180 MW-1-MW-Ghent Wicker Wing type" developed by the wing type of Northwestern Polytechnical University and the national key laboratory of the leaf grid air dynamics. The first successful application of the largest number of wind machine blades.

Wind power is a renewable clean energy. In order to achieve the "double carbon" goal, my country has developed the wind power industry in recent years, which has become a large air power country and the world's number one in the world. The wing type is the basic element of the blade of the wind machine, and is the basis of the design of the blade of the wind machine. The development of high -performance wing type suitable for large wind machine leaves is of great significance for improving the ability of the blade wind to capture, reducing weight to saving manufacturing and transportation costs, reducing inertial loads, and gust -load. However, the design of wind machine blades in my country has long relying on the wing types of the Netherlands, Sweden and other countries, not only to pay high usage fees, but also facing the situation where core technologies are subject to people.

The National Key Laboratory of Western Wing Big Wings and Leaf Cursery Air Dynamics has cooperated with Jilin New Materials Co., Ltd. in 2021 to give full play to the advantages of aviation wing -type air power design technology A number of key technical difficulties such as accurate predictions, multi -target global optimization, refined wind tunnel tests such as accurate prediction, multi -target global optimization, and refined wind tunnel are faced.

Teachers and students of key laboratories and Jilin to focus on leaders and technicians to conduct exchanges and discussions of wind -wing -type and blade design

Professor Han Zhonghua, the director of the laboratory, introduced that "NPU-MWA Dorova-grade windpower wings" is independently developed with the support of the relevant plan of the Ministry of Science and Technology. It includes 8 wing types from 18%to 60%of the relative thickness. Design excellent characteristics such as Renault number (9 million), high design lift coefficient (greater than 1.2), high lift ratio, and low roughness sensitivity. The successful application of this wings -type family is an important milestone in my country's independent wind -wing -type research. It is also the characteristic and advantage of the laboratory to give full play to the characteristics and advantages of wing -type research, and to achieve another iconic result of production -university -research cooperation. Get rid of the passive situation of long -term dependence on foreign wings and core technologies to ensure the source innovation and leapfrog development of domestic wind power blades.

Jilin's importance of Chengfei is an executive director of the China Renewable Energy Industry Association, and high -tech enterprises in Jilin Province. There are five major manufacturing bases in Jilin Da'an, Chongqing Luo, Inner Mongolia, Xilinhot, Gansu, and Jiangsu. The models of land and sea wind wheels have an annual output of nearly 2,000 sets of wind wheel blades. They are the mainstream supporting enterprises of domestic wind wheel leaves.

Next, the two sides will further strengthen cooperation in the improvement of the Muwa -grade windpower wing -type improvement, blade gas/structural coupling analysis and design, break through the core key technologies, and break the design of foreign wind -wing -type and large blades in foreign countries. Blocking. The national key laboratory of wings and grid air dynamics will also continuously improve the wing -type spectrum system, develop new wing types for large and small wind machine blades to help my country achieve the "double carbon" goal.
