On April 24, the ninth "China Aerospace Day" main event kicked off, and the "Aerospace Science Popularization Series Exhibition" was unveiled at the Wuhan International Expo Center on the same day.
It is reported that in order to provide a better experience for the general public, the "China Aerospace Day" series of aerospace science popularization exhibitions will take measures such as "real name, reservation, and current restriction". From the afternoon of April 24, the reservation channel will be opened, and the limit of 5,000 people will be reserved for each half-day. The Aerospace Industry Achievement Exhibition will be open until April 27, and the Science Popularization Exhibition will be open until May 5, both from 9:00 to 17:00.
The birthday weather is "one-click direct", and the citizens seem to be in space

Located in the B6 hall of the popular science exhibition area by the preface hall, space technology, space science, space applications, aerospace public welfare and other five sections, according to the real ratio of 1:1 made of space station core module, space pumpkin and other exhibits as the highlights, at the same time set up a number of interactive experience equipment, supplemented by a large number of models and wonderful pictures, the public shouted: "as if in space".

The reporter walked into the space technology lunar exploration engineering section, and the main parachute of the "Chang'e-5" return capsule and the "Chang'e-5" returner were stunningly "unveiled", and the simulation models of the Chang'e-5 lunar soil samples and the "Yutu" lunar rover model were simultaneously placed in it, revealing the "mystery" of the moon to the public. The corner of the section is also set up with the future lunar exploration VR scene and the virtual reality system of the lunar landing area, where the public can not only "roam on the lunar surface", but also become "lunar soil extractor" and "planting researcher", and enter the lunar scientific research station to complete the "task". "It's amazing, it's like you're really walking on the surface of the moon!" Ms. Zhou, a citizen, sighed after the experience.
Enter the place of birth and the date of birth, and use the Fengyun meteorological satellite "one-click direct" to query the weather of the day. The reporter saw at the scene that many citizens and friends came to watch and inquire. It is reported that the Fengyun meteorological satellite is an important piece of China's space infrastructure. After more than 50 years of development, China has become one of the countries and regions that have both polar-orbital and geostationary orbit meteorological satellites, so that "the sky can be measured".
The "Writing Robot" restores the real scene of the exhibition area
Walking into the aerospace industry achievement exhibition area of Hall B5, the reporter saw that the exhibitors were "equipped with unique skills" and tried their best to show the achievements of the aerospace industry in achieving independent innovation, leapfrog development and international cooperation.
The "Kuaizhou" unveiled in the exhibition area, its "Sanping test and launch mode" does not need to assemble and refuel at the launch site, does not need a huge launch frame and launch site, and the rocket can be launched by pulling the rocket to an open space the size of a basketball court by the launch vehicle.

Take a photo, convert the picture into "dots and straight lines" through algorithms, and then use the "writing robot" to control the program, and the real picture will come to life within ten minutes. According to the relevant staff of the exhibition area, the "writing robot" is actually a three-axis motion system, which is used in the automatic measurement and analysis of electronic product circuit boards, etc., the system can quickly locate fault nodes and realize the "no drawing detection" of circuit boards, and has now entered the aviation product testing stage.
In recent years, Wuhan has listed the aerospace industry as a key strategic emerging industry, seized the development opportunities of the global commercial aerospace industry, and introduced a series of policies and measures to accelerate the construction of the national aerospace industry base.
The exhibition area has a special Hubei booth, and Hubei colleges and universities join hands to go to the sea of stars

A special exhibition area of Hubei aerospace was set up at the exhibition site to show the achievements, latest achievements and development trends of Hubei's participation in the aerospace industry. The reporter noticed that the research results from Wuhan University, Wuhan University of Technology, Wuhan Textile University and other Hubei universities were displayed. "With stunts", they joined forces to go to the "sea of stars".
Walking into the Hubei booth in the aerospace industry achievement exhibition area, a series of satellite models took the lead in entering the reporter's field of vision. The "Qixing-1" micro-nano satellite on display at the booth of Wuhan University is the first remote sensing satellite developed by students in China.
During the flight of the aerospace vehicle, the flame temperature of the engine is extremely high, which causes serious high-temperature ablation of the hot end parts of the engine, which may cause the risk of early damage of the aircraft. According to the person in charge of the exhibition area, Professor Cao of Wuhan University of Technology led his team to develop ultra-high temperature thermal protection coating materials, designed a new coating structure, which has been widely used in aerospace, aviation, gas turbines and other power systems, "Compared with the traditional ceramic coating, the new coating developed by our team has better high-temperature performance, and the average 'life' of the coating has been significantly improved, which can bring longer stable service time to the engine." ”
flew into outer space, and the brightest touch of Chinese red. The Chang'e-5 lunar flag, which was completed by Xu Weilin, academician of the Chinese Academy of Engineering and president of Wuhan Textile University, was simultaneously unveiled at this popular science exhibition by the team of Xu Weilin, who lasted eight years and continued to tackle key problems. It is reported that this is the first time that the mainland has realized the "independent display" of the five-star red flag on the surface of the moon, and it is also the first textile-fabric version of the national flag under harsh environmental conditions without temperature control.
"To explore the vast universe and develop the aerospace industry, we will unremittingly pursue the sea of stars. Chen Wenbo, an associate researcher at Wuhan University of Technology, said.
