1935, 24-year-old Qian Xuesen published an article "Rocket" before studying in the United States. In the article
, he proposed the idea of three-stage rocket , rocket aircraft and interstellar navigation with the help of rockets from a comparative analysis of factors such as rocket fuel, technology and safety.
, an idea that was almost like a fantasy at the time, has now been realized. Moreover, the several high-performance propellant mentioned in the article at that time were also successfully used on the new generation of launch vehicle in my country.
Scientific research is a process of bold assumptions and careful verification. As the founder of our country's " two bombs and one satellite ", Qian Xuesen's "bold assumptions" have not been more than this time.
1992, when China was still carrying the label of "bicycle kingdom", Qian Xuesen suggested to the country to bypass traditional gasoline and diesel cars, develop new energy vehicles, and directly enter the new era of automobiles! The suggestion of
was puzzled at the time, but now it seems that Mr. Qian is really worthy of being a scientist who has always been at the forefront of the times.
Scientific prediction Electric vehicles development
After the founding of New China , when we developed industry on the basis of poverty and backwardness, the United States and other Western countries have long been ahead of us for many years.
At that time, the main means of transportation for Chinese people was still bicycles. Although there were also cars, the number was very rare, and their production capacity was much behind that of developed regions such as Europe and the United States.
Even if my country independently developed the "Hongqi" sedan, its performance was unstable. Once, during a foreign affairs event, the Hongqi sedan had a use failure.
Although the automobile industry is not comparable to developed countries such as Europe and the United States at that time, no one doubted my country's independent research and development and production capacity. It is also the wish of every Chinese to have an automobile industry that can match Europe and the United States.
Although Qian Xuesen's main focus is not Qian Xuesen's direction, he has also paid attention to this field.
In 1987, when Qian Xuesen visited the Federal Republic of Germany and the United Kingdom, he predicted that by 2020, the number of cars in China would exceed 10 million.
Qian Xuesen has always been scientific and forward-looking. From the amount of automobile usage, he has already keenly foreseeable that future energy use problems and environmental pollution problems will inevitably become an inevitable problem for mankind with the rapid development of industry.
After observation and thinking, and in combination with the fact that foreign countries have begun to study high-efficiency batteries, he wrote a letter directly to suggest:
The automobile industry should skip the automobile diesel stage and directly enter the new energy stage to reduce environmental pollution.
He believes that the foreign automobile industry is already much ahead of us. Under this situation, China should not be catching up with the pace of Europe and the United States step by step, but should organize forces, skip this adjustment, and directly enter the new era of the automobile industry.
After receiving Qian Xuesen's suggestion, the country also attached great importance to it and regarded the "Electric Vehicle Research Plan" project as a national key scientific and technological research plan in the "Eighth Five-Year Plan".
Comrade Zou Jiahua, who was then Vice Premier of the State Council, also wrote a reply to Qian Xuesen, in which he discussed the research issues of new energy vehicles with him.
Like foreign research, we need to study "electric vehicles". Efficient batteries are the key, and Qian Xuesen also put forward his own opinions based on the physical knowledge he has mastered.
Today, although my country's automobile industry is still far from that of Europe, America, Japan and other countries, it is at the world's advanced level in the field of "electric vehicles". This is inseparable from the efforts of scientific researchers and witnessing Qian Xuesen's forward-looking nature in this field.
And domestic cars have an increasingly greater influence in the world.
In June 2022, when Musk, president of " Tesla " electric car, visited Brazil , the vehicle used by the local government to receive was the Tiggo 8, a subsidiary of the domestic Chery sedan.
Qian Xuesen, who predicted the prospects of China's automobiles, naturally made many forward-looking predictions in the fields he is familiar with.
5 Five years of return home, two bombs became
0 Qian Xuesen is a world-renowned expert in aerodynamics. He was born in 1911. After studying in the United States for public expenses in 1935, he entered the famous Massachusetts Institute of Technology to study aviation engineering. After obtaining a master's degree in
, he became a teacher at the famous American astronaut Von Carmen and obtained a double doctorate in aviation and mathematics from California Institute of Technology.
After , as an aerodynamic expert, Qian Xuesen was sent to Germany to learn about rocket technology.
These experiences laid the foundation for him to become a founding hero of our country's "two bombs and one satellite".
But because of Qian Xuesen's achievements in the United States, when he wanted to return to his motherland, Kimbell, then the deputy chief of the US Navy, said: Qian Xuesen can stand up to five divisions by himself.
Jinbeier also suggested that the United States should not leave Qian Xuesen in the United States, then kill him.
In the summer of the second year after the founding of New China, the happy Qian Xuesen brought his luggage, books and notes, preparing to board the ship "President Wilson" to Hong Kong.
However, due to political reasons, Americans do not want to see this first-class rocket expert return to China, so they detain Qian Xuesen in a detention center on Temina Island on immigration.
Later, because of Qian Xuesen's protests and the help of American friends, US Immigration Bureau had to release Qian Xuesen, but he closely monitored his every move.
Later, with the strong mediation of the motherland, Qian Xuesen took his wife and children for two months and finally returned to the motherland.
From the summer of 1950 to the autumn of 1955, Qian Xuesen took a full 10 years to return home.
Even though he encountered many difficulties and obstacles, Qian Xuesen never changed his original intention of serving the country.
After returning to China to sort out his own research, he proposed to the Central Committee of the Communist Party of China and the State Council to establish my country's national defense aviation industry.
According to Qian Xuesen's suggestion, the Central Military Commission quickly established the Aviation Industry Committee and formulated the first five-year scientific plan. Qian Xuesen was also ordered to establish China's first rocket and missile research institute.
After ten years of hard work, in 1966, a medium-range missile carrying atomic bomb took off from the Jiuquan launch site. After the missile was successfully launched, nuclear warhead hit the target accurately.
This successful test marks that my country can independently design and manufacture nuclear missile . This result, thanks to Qian Xuesen's participation, has been completed at least 20 years ahead of schedule.
However, Qian Xuesen's contribution to China is more than that. In addition to strategic weapon , such as the atomic bomb, as an aerodynamic expert, Qian Xuesen is also the founder of my country's aerospace industry.
Just after the first lesson of my country's atomic bomb explosion was successful, Qian Xuesen couldn't wait to suggest to the country that " artificial satellite " would also be included in the national development task.
In 1968, Qian Xuesen was ordered to lead the team to be responsible for the research and development of China's first rocket.
After two years of intense work, on April 24, 1970, China's first artificial satellite " Dongfanghong-1 " successfully entered space and entered a predetermined orbit on the "Long March 1" rocket.
The melodious singing resounded throughout space, and the Chinese once again announced this new technology to the world. The State Council also designated April 24 as China Space Day .
In 2003, when China's first hero to fight in space, Yang Liwei and successfully returned, he also visited Qian Xuesen, the founder of the motherland's aerospace industry.
In addition to its contribution to my country's aerospace and missile industry, as a physics expert, Mr. Qian Xuesen also has his own unique insights in scientific theory.
's prediction of the meta-universe - Ling Realm
Qian Xuesen's mentor Feng Carmen said that Qian Xuesen has both rich imagination and mathematical talent of Chinese people, and this kind of talent is very rare.
When studying at Caltech, Qian Xuesen created the "Money-Carmen" equation, solving the mathematical calculation problem of deforming the fuselage and wings when the aircraft flies at high speed.
At the same time, Qian Xuesen also solved the " thermal barrier " problem in the aviation industry. The solution to this problem is of great significance to the development of rockets and missiles.
The so-called "thermal barrier" is the heat generated by the strong friction between the air on the surface of the fuselage and the air when the aircraft is flying at high speed. When this temperature rises sharply and exceeds the limit temperature of the aircraft surface material, it will destroy the aircraft. After the new discipline of
was released, it immediately attracted the attention of the scientific community. It is no wonder that the United States does not want him to return to China with such a genius.
" Engineering Cybernetics " is another creation of Qian Xuesen, and it is a brand new discipline he created.
The subject is a research completed by Qian Xuesen under the strict surveillance of the United States after he wanted to return to China and was obstructed by the United States.
After the publication of "Engineering Cybernetics", it was translated into Russian , German and other texts.
Before returning to China, Qian Xuesen gave this book to his teacher as a parting gift. Feng Carmen also praised Qian Xuesen as his pride. Although he was Qian Xuesen's leader, Qian Xuesen's academic achievements have surpassed himself.
In addition to engineering theory, Qian Xuesen, who has always been knowledgeable, also has his own advanced insights on the concept of " meta-universe ".
"Metauniverse" is virtual reality. Zuckerberg, founder of Facebook
Facebook (Facebook ), has previously described the "metauniverse" to people: even if they are in two places, they are connected to the Internet through computers, and people will communicate with each other in the same room as if they are in the same room.
In the developed Internet society, this function has been implemented through chat software, but in an era when mobile phones were not popular more than 30 years ago, Qian Xuesen had the idea of "meta-universe".
In the early 1990s, computers were still a tool dedicated to the field of national defense, but after understanding computer and Internet technology, Qian Xuesen, who was already 79 years old, became keenly aware that a new era was coming.
In a letter exchange with friends, Qian Xuesen believed that this virtual "metauniverse" will be another technological revolution after the computer technology revolution in humans.
He also believes that the literal name of "virtual world" has no "Chinese flavor", so he gave this brand new universe a name "spiritual realm".
In addition to "spiritual realm", more than vocabulary of more than 10 professional words such as high supersonic , automatic control, missile, laser light, 20 were also created or translated by Qian Xuesen.
However, Qian Xuesen's creation does not lie in these proprietary terms. In addition to his contribution to national defense technology, his scientific forward-looking nature is even more valuable.
"Spiritual Realm" is a bold prediction based on his scientific understanding. Now this prediction, which seemed a fantasy at that time, has begun to take shape, which also witnesses Qian Laofan's scientific prospects.
Conclusion
Although Mr. Qian has passed away now, as a world-renowned scientist, the wealth he left us is infinite.
The series of innovations in applied mechanics, physical mechanics, , engineering cybernetics and aerospace are still leading generations of astronauts to explore the universe.
He is the well-deserved father of China's space, the father of missiles and the king of rockets . This is also the reason why Yang Liwei, the first Yang Liwei who entered space, went to visit Mr. Qian when he returned successfully.
