On the morning of November 3, the 2020 National Science and technology award conference was grandly held in the Great Hall of the people in Beijing. Academician Gu Shufen of AVIC and Academician Wang Dazhong of Tsinghua University won the national highest science and technology award. (reporter Chen Fang, Hu Zhe, Wang Linlin) < / P > < p > Gu Songfen, winner of the national highest science and Technology Award: he has devoted himself to aviation for the country < / P > < p > ZHENG Weiwei / CCTV news < / P > < p > Gu Songfen, winner of the national highest science and Technology Award in 2020, academician of the Chinese Academy of Sciences and academician of the Chinese Academy of engineering, has been engaged in aviation for 70 years. He is a prestigious aircraft design master in New China, He led the design of J-8 and J-8 II series of high-altitude and high-speed fighters, which has made outstanding contributions to the development of China's aviation industry < p > Gu shengfen's fate with the plane began in his youth. In 1935, Gu shengfen, 5, moved to Beijing with her parents. In 1937, the July 7th incident broke out, and he was deeply impressed by the bombing of Japanese planes at that time < p > Gu Songfen, winner of the national highest science and Technology Award in 2020: Japanese planes lined up neatly to the west, followed by the bomb. So this is very impressive. If there is no aviation, you will have to be bullied in the future < p > the bombing of Japanese planes made Gu Songfen's heart burn the dream of saving the country by aviation. In 1951, Gu shengfen graduated from Shanghai Jiaotong University majoring in aviation engineering. At that time, the aviation industry of new China started hard from scratch. Since then, he has been holding his breath and determined to design Chinese people's own aircraft < p > Gu shengfen, winner of the national highest science and Technology Award in 2020: Although the Soviet Union gave us aircraft, they are almost eliminated. If so, if people hold your key, you can't move forward. We can only rely on ourselves to develop new and good aircraft < p > in 1956, the first aircraft design office of new China was established in Shenyang. The first task of the aircraft design office was to independently design a jet trainer - Jian jiao-1. Gu shuofen is responsible for pneumatic layout design, but he knows nothing about this new field < p > Gu shengfen, winner of the national highest science and Technology Award in 2020: the first level, the aircraft must be air intake on both sides. We haven't learned how to design the air inlet of jet aircraft in school, and they don't know very well < p > j-jiao-1 aircraft should adopt air intake on both sides. At that time, they were most worried about the air inlets on both sides. If the scheme of air inlet on both sides is adopted, there may be air inlet on one side and air outlet on one side, which is bound to cause engine surge. In order to verify this phenomenon, Gu shengfen and his colleagues spent their brains < p > Gu shengfen, winner of the national highest science and Technology Award in 2020: the factory run hospital has a lot of needles every day. Collect that thing, then hinge the needle and weld it on the copper pipe, so that I have a device to measure the air flow < p > the first generation of Chinese aviation people tried their best to design their own aircraft with a belief and their own indigenous methods. On July 26, 1958, the first flight of Jian jiao-1 aircraft was successful, which was the beginning of China's aviation industry from aircraft repair and imitation to self-designed jet aircraft, marking that China's aviation research jumped to a new level < p > Gu shengfen, winner of the national highest science and Technology Award in 2020: on the first day of test flight, everyone was nervous and happy, and when taking off, everyone was worried; When they waited, everyone was elated and threw up the pilots < p > as the founder of Chinese aircraft aerodynamic design, after the completion of J-1, Gu shengfen received a new challenge. He and his team need to design a fighter comparable to the world's most advanced level, which is J-8 < p > Gu shengfen, winner of the national highest science and Technology Award in 2020: at that time, the United States and the Soviet Union had supersonic aircraft, even bombers, so there must be new aircraft, which was better in speed and altitude < p > high flying, long flying time and strong firepower have become the targets of J-8 development. While everyone was struggling, an accident happened. Huang Zhiqian, the then chief designer of J-8, died in a plane crash while performing a mission abroad. In the face of danger, Gu shengfen and his colleagues took over the burden of the chief designer < p > in those special years, Gu shengfen and his colleagues overcame countless pressures and difficulties. On July 5, 1969, the J-8 made its first successful flight. It is the first high-altitude and high-speed fighter designed by China. It has become an important milestone in the development history of China's aviation industry < p > although the first flight of J-8 was successful, there were several buffeting problems caused by air flow separation in transonic and subsequent supersonic flight tests. In the words of pilots, it was like a broken bus driving on an uneven road < p > Gu shengfen, winner of the national highest science and Technology Award in 2020: where is the air separation in the rear fuselage? I think of a way, only stick a wool top, a packet of red thread, cut it into such long sections, and stick it on the whole vertical tail and rear fuselage with adhesive tape < p > in order to observe the vibration of wool sliver, Gu shengfen, who had never received flight training and was over 50 years old, made a bold decision: go to heaven by jianjiao-6 aircraft and directly follow the test aircraft to observe the flow. The risks are self-evident: the two aircraft must maintain close constant speed flight, with a distance of about 10 meters or even closer. If they are careless, the consequences will be unimaginable < p > Gu shengfen, winner of the national highest science and Technology Award in 2020: (pilot) Comrade Lu Mingdong said a word that I have never forgotten. He said that the problem of life and death has long been solved for us. We solved this problem when we were pilots, and we also didn't keep our own affairs in mind < p > Zhao Xia, chief model designer of Shenyang Institute of aviation industry: in her 50s, when a fighter makes a circle around a corner, four g (gravitational acceleration) is normal. Not everyone can be a pilot. But Mr. Gu didn't care so much at that time, and then sat down three times. In fact, it was a great challenge to his body. He really took his life to do this business there < p > after three celestial observations, Gu found the crux of the problem and successfully solved the chattering problem of J-8 in transonic and supersonic flight through later technical R & D and improvement. At the end of 1979, the J-8 was finalized successfully. For more than 30 years since then, J-8 series aircraft have become the main fighter in China's territorial air defense operations, effectively safeguarding China's airspace security < p > national top science and technology in 2020 ?
