China's aerodynamic research ranks first in the world

Researcher working in a wind tunnel

From conventional wind tunnels to special wind tunnels, from wind tunnel testing to a single approach to the integration of the three approaches, from providing experimental data to leading innovation in model development... After more than 40 years of hard work, China Aerodynamics Research and Development Center has become a world leader in scientific research capabilities. Go ahead. Recently, the reporter saw in the center's new research and experimental zone that dozens of modern wind tunnels are dotted with more than 100 state-level key scientific research projects. Dozens of key aerodynamic problems have made historic breakthroughs.

The wind tunnel is called "cradle of aerospace vehicle" and it is considered as an important strategic resource by all countries in the world. In May 2010, the China Aerodynamic Research and Development Center initiated the construction of a new research and experimental zone. According to the director of the center, Qi Xiangxin, a variety of new types of aircraft have achieved model flight tests for the first time in the new scientific research and experimentation area, and millions of data have been classified and stored. The center has now fully implemented wind tunnel tests, numerical calculations and model flights.

“Note to each post, the following preparations will be made to start the spraying.” “Understand, spray begins.” The reporter saw the scene of the icing test of a large aircraft tail fin in the first icing wind tunnel test site in China. Senior engineer Liu Zhengchong told the reporter that the freezing wind tunnel is the key to the study of the high altitude flight icing, defense, and deicing technologies. This frozen wind tunnel has completely independent intellectual property rights and various technical indicators have reached the world's advanced level.

Following the icing wind tunnel, a new type of wind tunnel was built at the center: a new type of wind tunnel provides advanced ground test methods for China’s manned spaceflight and deep space exploration; the first large-scale aeroacoustic wind tunnel is an aircraft. The test and evaluation of aerodynamic noise from ground vehicles provides important technical support; a hypersonic low density wind tunnel lays a solid foundation for the development of rare gas dynamics and other disciplines in China.

Since the "Twelfth Five-Year Plan," the center has completed more than 1,500 aerodynamic test tasks for a series of key projects such as manned space flight and the moon exploration project, and has obtained a batch of innovative research results with world-leading levels, providing development for new types of aerospace vehicles. Reliable pneumatic data has played an irreplaceable role in the design and evaluation of aerodynamic and aeroacoustic performance of domestic products such as large aircrafts, wind turbines, and EMUs.
