In 1941, the Anti-Japanese War broke out and Fuzhou fell. In order to avoid the indiscriminate bombing by the Japanese army, the common people had to stay vigilant at all times to hide in the cave to escape.
During the raids of the enemy forces, the plane flew very low, and the villagers could only hide in the coffin cave.
But the rumbling of the plane scared the child into tears. At that time, a mother was holding a baby in her arms. In order to prevent the baby’s crying from attracting enemies, the mother had to hold it vigorously, causing the child to feed directly. When I was suffocated. This scene of
caught a child named Chen Yijian in his eyes and remembered.
He said, "At that time, I felt that only people had airplanes. How could we not. At that time, I was in middle school and I was young and not very sensible. I just felt powerless, as if there was no way at all. Being humiliated is like being beaten. A kind of feeling, painful to the skin. After I signed up for volunteers, all three of my volunteers were aviation. This kind of stimulation to a person lasts a lifetime and cannot be relieved." Z1z
Later, this child became the father of "Flying Leopard". At the age of 58, China's first fighter-bomber came out.
On June 21, 1930, Chen Yijian was born in Fuzhou City, Fujian Province. His father Chen Zhaoqi had studied in Japan. After returning to China, he taught in the Department of Mechanical Engineering of Fuzhou University. Therefore, when Chen Yijian was young, he always heard his father say that only technology can save China. .
In 1952, after graduating from the School of Aeronautics of Tsinghua University, Chen Yijian was assigned to the Harbin Aircraft Factory, responsible for repairing wounded aircraft on the front line of the Korean War to Resist US Aid Korea and imitating the Soviet Il-28 light bomber.
A few years later, Chen Yijian was transferred to the 60l Institute of the Sixth Institute and began to study the overall design of aircraft, aerodynamics, strength, structure, systems and other professional aircraft design. But it didn’t take long for Chen Yijian to be involved in the catastrophe of the times. He was arranged to clean the pigsty, feed the pigs, and farm the land.
But even so, Chen Yijian is still reluctant to give up his professional knowledge. He always reads the fatigue and fracture theory of airplanes secretly every night, and completed the first airplane fatigue test outline in our country.
Since then, my country has ended the history of aircraft development with reference to foreign general fatigue load spectra.
In 1974, my country’s Paracel Islands were threatened, and my country urgently needed to develop a weapon that could deter the enemy in peacetime and win local wars in wartime.
Three years later, the fighter-bomber "Flying Leopard" was formally established, and Chen Yijian was appointed as the chief designer. The ups and downs of
finally came into use. Chen Yijian was very excited. In order to be able to invest in research as quickly as possible, Chen Yijian took the team to study abroad, but after arriving in Germany, Chen Yijian was stimulated again, because at that time, Germany The company didn't put Chen Yijian in its eyes at all. They didn't allow them to observe all the equipment by themselves, and could only let them "look at it from a distance." Z1z
is not only that, the other party also said: "The cooperation conditions offered at the time were very harsh: the core technology was not given, and the asking price was 2.1 billion. The negotiations ended up unhappy and broke up." Chen Yijian
said with a heartbreak on the way back to China: Without technology, we will explore ourselves, and without precedent, we will create a precedent.
was just when he was ready to do a big fight, because of the adjustment of our national economy, the army construction at this time had to make way for economic construction, and many new equipment research and development plans were forced to terminate.
"Flying Leopard" also had to significantly reduce scientific research funding.
Seeing "Flying Leopard" was about to die, Chen Yijian cried when reporting to his superiors. After
, even though the country stopped the research and development expenses for a year, Chen Yijian still took all the researchers to draw a stack of design drawings, and they made up their minds as soon as they went in: "Just buy paper and pens. If there is money, the design of "Flying Leopard" will not stop." In order to seize every second of development time, all employees of the plant began to work day and night. No one in dual employees took their children, so they brought the children. Sleeping in the office, it is common for children to roll off the shelf.
After 10 years of dormancy, "Flying Leopard" made its public debut at the Zhuhai International Air Show.
This day marks that China's aviation industry has achieved a historic leap from surveying and mapping imitation to self-development.
The total development funding for "Flying Leopard" is only 100 million U.S. dollars, which makes foreign media have been lamented: "Uncomprehensible, unimaginable!"
But what they don’t know is that the 2 billion U.S. dollars saved is the result of Chinese scientists. Intensity laboratories were built on the pigpen, and experiments were done in straw mat sheds.
Although the "Flying Leopard" succeeded in its first flight, Chen Yijian still had a big trouble in his heart, because he knew that the "Flying Leopard" had a fatal problem with vibration.
In 1992, the "Flying Leopard" flew at an altitude of 5,000 meters and at Mach 1.07 during a transonic flight. There was a very severe vibration. When it decelerated, it heard two noises and the rudder flew off.
This put him under tremendous pressure. Chen Yijian judged through the accident that the reason why the rudder was shaken off was because the aircraft “hummed” when it crossed the speed of sound and was affected by shock waves. For this, he used It took more than a month to change the rudder design and eliminate the malfunction.
On October 1, 1999, during the military parade on the 50th anniversary of the founding of the People's Republic of China, an air echelon composed of six "Flying Leopards" flew neatly over Tiananmen Square.
Chen Yijian watched his "child" rush into the blue sky proudly.
In that year, Chen Yijian was 69 years old. He said: "The Flying Leopard was hard-won!"
In November 2020, Chen Yijian won the 14th Aerospace Laurel Award for Lifetime Dedication.
He said: "For more than ten years since winter and spring, the pictures are tens of thousands of rolls, and the temples are like frost. The bitter and sour, and the hand-rolled Pingchuan. The late faint is like a naughty child, serving China and comforting my ancestors."
