After selection, Qin, a CNC milling machine worker in Hafei, the aviation industry, and Cao, a CNC milling machine worker in the Second Academy of Aerospace Science and Technology, were awarded the Grand Craftsman Award respectively. China Eastern Airlines Shanghai Flight Department was awarded the Flying Elite Award; Aviation industry Li Hongguang's airborne airdrop test jump team won the heroic fearless award; Dong Li, chief designer of the Long March 5 rocket series, and Deng Jinghui, chief designer of the Aviation Industry Helicopter Design Institute, won the Technology Pioneer Award; Wang Jinsong, president of Northwestern Polytechnical University, and Chi Jun, commander-in-chief of Beidou-3 satellite, won the Outstanding Leadership Award; China Commercial Aircraft and China Aviation Industry won the Cooperation Award; Chen Yijian, an academician of China Academy of Engineering and a master of aircraft design in China, and Yin Zeyong, an academician of China Academy of Engineering and an aero-engine expert, were awarded the Lifelong Dedication Award. ?
Zhou Guoqiang, spokesperson of Aviation Industry Group: This year, 12 individuals and teams were selected, representing the best people in the aerospace industry in the past two years. Like lifting us? Tian Wen No.1? The Changwu rocket to Mars, such as the large amphibious aircraft AG600, which just made its first flight at sea this year, and the great country heavy weapon Zhi -20, are all within the scope of our award-winning projects and personnel. ?
Aerospace Laurel Award was founded in 2005. It was held once a year before, and it was held every two years from 20 18. It aims to commend units and individuals who have made outstanding achievements in the aerospace field, national science and technology development and national defense construction. ?
After 14 years of development, Laurel Award has become an industry award with high social influence in the aerospace field. Up to now, * * * has obtained 127 teams and individuals. Including Sun Jiadong, a meritorious scientist with two bombs and one satellite, Gu Songfen, an academician of the two academies, Yang Liwei, an astronaut, and Li Zhonghua, a hero of flight test, are all previous winners. ?
Among the laurels awarded in the aerospace field today (18), there is a technological pioneer award, which represents the breakthrough research achievements in the aerospace field in the past two years. One of the winners is Deng Jinghui. He is the chief designer of the Aviation Industry Helicopter Design and Research Institute. As the technical director and team, the fourth-generation helicopter made in China, Zhi -20, was developed.
Deng Jinghui: Zhi -20 is our fourth generation helicopter, which represents the highest level in our country at present. It can soar freely in the whole territory on the land of 9.6 million square kilometers of our motherland because it embodies the crystallization of the painstaking efforts and wisdom of countless aviation people. ?
Although he witnessed its participation in the 70th anniversary military parade and its stunning appearance at the helicopter air show, Deng Jinghui was still very excited when it came to Zhi -20. Since 1986, Deng Jinghui has been rooted in the helicopter industry, and has witnessed China's helicopters reaching the world advanced level in 34 years. ?
In 2008, a major earthquake occurred in Wenchuan. What we saw on the screen at that time were all foreign helicopters. There are no helicopters on the plateau. Therefore, the establishment and development of tactical general helicopter is carried out under this background. ?
If we want to develop a plateau helicopter, we have to face a key technology that China has never conquered-rotor anti-icing. Below 7000m, when the helicopter passes through the low-altitude clouds with high water content, the rotor often freezes and cannot work normally due to the low temperature and high humidity. This is a worldwide problem. At the beginning of research and development, Deng Jinghui and his team also thought about achieving technological breakthroughs through foreign cooperation. ?
The foreign party cooperated to reduce the risk of model development, but it was rejected by the foreign party. Facts have proved once again that the core key technologies must be in your own hands, and you can't buy them with money. At that time, our team was secretly determined to fight for this tone and make the rotor anti-ice. ?
In fact, ten years before the Zhi -20 project was established, Deng Jinghui and his team had already started the preliminary key technology research of rotor anti-icing, and it took a full 20 years to formally develop the model after the project was established. In the past 20 years, he either led the team to study the seemingly boring experimental parameters at the design site, or went to the plateau snow and ran behind the test helicopter in the extremely cold, hot and humid field. ?
Deng Jinghui: We went to the plateau four times and went into the cold four times. We passed the test in the hot and humid environment in the south, which should be said to cover the whole territory of our country. ?
2065438+February 2008, Deng Jinghui and the scientific research team completed the last test flight verification in the snowy plateau with an altitude of more than 5000 meters in the northwest. This is the first time that the Zhi -20 has entered the real harsh environment to verify the anti-icing technology of the rotor, which is extremely risky. ?
In order to obtain valuable data, the flight test team that followed Deng Jinghui for many years rushed into the frozen clouds again and again and successfully completed the scientific research flight test mission. When the helicopter landed smoothly, Deng Jinghui and the development team were overjoyed. From that day on, China became the fourth country in the world to conquer the anti-icing technology of helicopter rotor. Zhi -20 also has full territory and all-weather combat capability. ?
