Chief Designer of 歼 8II Aircraft: Creating a "Competitive Aircraft" belonging to China people.

  Xinhua News Agency, Beijing, May 3rd Title: Creating a "competitive aircraft" belonging to China people: A record of Gu Songfen, academician of the two academies and chief designer of China’s J-8II aircraft.

  Under the background of "poor and white", the first jet trainer in China — — Fight against religion 1; Risking one’s life to fly into the blue sky by fighter plane three times, just to find out the plane design problem; "Ode to the heroic virtue of the world, recite the pure fragrance of the ancestors." With a pure heart for the motherland, he has presented the fruitful results of jet plane design and aerodynamic research in China … …

  Has won numerous honors, but never takes credit. Along the way, Lu Ge made a lifelong determination to let China people own "confident and competitive" aircraft: he is an academician of China Academy of Sciences and China Academy of Engineering, and the chief designer of China’s J-8II aircraft — — Gu Songfen.

  "A blank sheet of paper" made China’s first jet trainer

  Today, 87-year-old Gu Songfen recalls the indissoluble bond he had with the plane.

  In 1940, when the nation was in peril and foreign enemies invaded, 10-year-old Gu Songfen received a "special birthday gift" from his uncle — — A model airplane, "it was very rare at that time", Gu Songfen introduced, and he was out of control and immersed in the world of airplanes.

  During the war, air strikes and bombings even planted a seed in the young Gu Songfen’s heart. He secretly vowed: "We must make a plane belonging to China people!"

  With this seed, Gu Songfen went from youth to high spirits, from the Huangpu River to the snowy north.

  In August 1956, the former Aviation Industry Bureau established the first aircraft design room in New China in Shenyang 112 Factory. In this team of the best aircraft designers in New China, Gu Songfen assumed the position of leader of the pneumatic team.

  In order to solve the problem that the fuselage adopts two-side air intake, Gu Songfen digested, combed and summarized all the information he could collect, and finally formed a set of methods for aerodynamic design and calculation, successfully completed the selection and calculation of airfoil and wing-body combination type, the determination of inlet parameters and the calculation of data needed for overall design.

  Nothing is difficult in the world. Gu Songfen, together with military experts, used the only wind tunnel that had never been used in engineering at that time, groped and experimented, and finally achieved ideal results. According to Gu Songfen’s memory, in the case of extreme shortage of materials, after work during the day, he had to take his colleagues to the hospital to collect waste needles and weld them on copper pipes to form a model … …

  On July 26th, 1958, the first flight of J-J-1 plane was successful in Shenyang. Gu Songfen created the aerodynamic design method belonging to China people in the almost blank new China aircraft design career, and also reached a new peak in the research and practice of applied aerodynamics.

  In order to find problems for the plane, I flew into the blue sky by fighter plane III.

  On July 5, 1969, the J-8 aircraft made its first flight. However, in the subsequent flight test, the plane appeared strong vibration, which made all the participants hang up their hearts.

  In order to solve this problem completely, Gu Songfen made a bold decision: take the J-6 plane to the sky in person and observe the vibration directly behind the test plane!

  According to Lu Mingdong, the test pilot who was flying the plane at that time, "Mr. Gu was nearly half a year old at that time, but regardless of the impact of overload on his body and the potential crash risk, he resolutely took a telescope and camera and observed and photographed the dynamics of the plane at an altitude of 10,000 meters, which made all the comrades present very shocked and moved."

  Li Tian, an expert in aircraft aerodynamics and an academician of China Academy of Sciences who is also a friend of Gu Songfen, also witnessed this "feat" at that time. According to Li Tian’s memory, another teacher of Gu Zong — — Huang Zhiqian, the first chief designer of the J-8 plane, died in an air crash. Gu’s wife, Jiang Zefei, had an agreement with him: she would never fly again. This is not out of distrust of the safety of the plane, but because we can’t bear the pain of losing our loved ones.

  This time, Gu Songfen is not going to board a large civilian plane, but a fighter with higher risk! Therefore, he must hide from his wife and everyone in his family. Gu Songfen himself admitted that he didn’t have time to think so much at that time.

  The work is dedicated to ambition, and the industry is broad and diligent. Thanks to repeated observation and bold attempts, Gu Songfen finally solved the problem of serious airflow diversion with the team, and personally designed the fairing of the rear fuselage of the aircraft to completely eliminate the transonic buffeting of the aircraft.

  Family learning is handed down from generation to generation, and the belief in knowledge will never change.

  Gu Songfen is often asked a similar question: "What are you doing this for?"

  For the name? For profit? Just for this long-term country.

  Gu Songfen, who is now nearly 90 years old, can still clearly remember the words and deeds of his father and other elders, and the loud noise when the invaders dropped bombs on him. Gu Songfen’s belief as a party member and an intellectual was constructed by this stillness, movement and relaxation. In his life coordinates, there are both the "blood" of Chinese culture flowing from Mr. Gu Tinglong, the father who is a cultural master and honorary curator of Shanghai Library, and the "pulse" of the first generation of intellectuals in New China who struggled hard. In Gu Songfen’s research career, the two "bloodlines" complement each other.

  What attitude should intellectuals take to live in the present? Feelings of home and country, and eternal faith in knowledge … … "Respect knowledge and fear knowledge." From Gu Songfen, we can see China’s answer given by an intellectual family that has passed down from generation to generation.

  "Learn technology and use technology; Learn knowledge and use knowledge. " Apply what you have learned and combine knowledge with practice. In Gu Songfen’s eyes, serving the country and strengthening the country is pure and determined.

  "To be able to make new creations, you must read more books." Today, the old academician who is nearly ninety years old is still "the first person to come to the office in the morning"; When you see the cutting-edge research results in foreign academic institutions, you will definitely share them with relevant young designers and step up your study with them.

  A thought still exists, and this ambition is unremitting. Even the most difficult moment, the most dangerous situation and the last day of life will not give up easily. This is Gu Songfen, a pure aviation man and a respectable intellectual.
