Summary of Qian Xuesen's patriotic deeds

Among the outstanding contemporary scientists in China, there are three people whose names are Qian Xuesen, Qian Sanqiang and Qian Weichang. They are called "San Qian". They all came back from studying abroad with the heart of serving the motherland. Among them, Qian Xuesen's experience is the most thrilling.

Qian Xuesen spent 20 years in the United States, made outstanding achievements in aviation science, became a famous rocket expert and made contributions to American military science. 1949, he was very excited when he learned that the new China was founded, and decided to go back to China to participate in the construction. However, the United States is hostile to China, fearing that Qian Xuesen's return to China would be detrimental to them, so it tried every means to obstruct it. The deputy secretary of the US Navy also said viciously, "I would rather shoot him than let him leave the United States. He knows too much, and one person can top five divisions! " Therefore, the US falsely accused Qian Xuesen of being a spy in China and arrested him. Although he was later released, he was still under close surveillance.

Qian Xuesen did not give in, lodged a solemn protest with the United States, and his determination to return to China was even greater. He put away three small boxes at home, ready to start at any time. After that, Qian Xuesen, who was detained by the US for five years under the questioning of the China government, finally returned to China by boat at 1955. He came to Tiananmen Square and said excitedly, "I believe I can definitely come back, and now I finally come back!" " "

After returning to China, Qian Xuesen made great contributions to China's missile and space undertakings and was one of the most prestigious scientists.

Qian Xuesen's patriotic story (2);

1947, China scientist Qian Xuesen, who just turned 36, was hired as a tenured professor by MIT. This is a high honor, which indicates Qian Xuesen's generous treatment and great prospects.

Why does the United States value Qian Xuesen so much? Because he is an excellent student of Von Carmen, the top expert in American aviation science, and one of the five members of the Rocket Research Group of California Institute of Technology, the earliest rocket research organization in the United States.

Under the guidance of von Carmen, rocket research has made great progress and contributed to the victory of the anti-fascist war. In those hard days, Qian Xuesen showed outstanding talent. An aviation science formula that occupies an important position in the history of aviation science: the famous "Carmen-Qian formula" was born. This is a formula put forward by von Carmen and made by Qian Xuesen, and it is still widely used in aviation technology research.

However, when Qian Xuesen learned the news of the founding of People's Republic of China (PRC), the scientist who had been thinking about his motherland was suddenly immersed in great joy. Qian Xuesen lived in the United States for more than 10 years, also known as "the first rocket expert in the United States", with money, status and reputation. But he thought: I am from China, and my roots are in China. I can let go of everything in America, but I can't let go of my motherland. I should return to my motherland as soon as possible and contribute all my strength to building a new China! He also told China students: "The motherland has been liberated, and the country urgently needs to build talents. We should quickly apply what we have learned to the construction of the motherland. "

Qian Xuesen's decision to return to China caused panic in the United States. They believe that if Qian Xuesen's expertise is brought back, China's science and technology will advance at a high speed. A leader of the US Navy once said to an American official in charge of leaving the country: "I would rather shoot Qian Xuesen than let him leave the United States!" Qian Xuesen is worth at least five divisions.

Qian Xuesen's plan to return to China was seriously blocked. Official American documents informed him that he was not allowed to leave the United States. It turned out that his luggage had been loaded on the barge and was ready to be transported back to the motherland by water. However, the US Customs insisted that the books and notebooks he wanted to bring back to China contained important secrets and slandered Qian Xuesen as a "spy". In fact, some of these books and notebooks are open textbooks, and some are Qian Xuesen's own academic research records.

A wave of unrest, another wave. A few days later, Qian Xuesen was suddenly arrested, detained in an island detention center and tortured. Every night, the guards come into the room and turn on the light every 10 minutes, which makes him unable to sleep at all. Qian Xuesen's experience aroused the sympathy of colleagues and students of California Institute of Technology who insisted on justice. Under the strong protest of them and other upright people, united states secret service was forced to release him. But the persecution of Qian Xuesen did not stop. They restricted his movements, monitored and checked his letters, telephone calls and so on. Despite all kinds of restrictions, Qian Xuesen did not give in. He kept making solemn demands: resolutely leave the United States and go back to China!

During his efforts to return to China, Qian Xuesen was more concerned with the construction of the motherland. He often learned about the situation of New China from newspapers and periodicals such as Overseas Chinese Daily, and discussed the construction of the motherland with China scientists and overseas students. In order to return to China quickly, he rented a house and signed a short-term contract I have prepared three light boxes at home, ready to fly back to China at any time every day.

Five years have passed. Qian Xuesen's struggle to return to China won the support of people who uphold justice all over the world, and also received great care from the China government. Premier Zhou Enlai personally understood his situation, and instructed the China delegates attending the Sino-US ambassadorial talks to raise the issue of Dr. Qian Xuesen's return to China during the talks.

1In August, 955, the diplomatic struggle finally won, and the US government was forced to allow Qian Xuesen to return to China.

The morning after his arrival in Beijing, Qian Xuesen came to Tiananmen Square with his wife and two children. He said excitedly, "I believe I can definitely return to my motherland. At this moment, I finally came back! "

Qian Xuesen, who broke through many obstacles to return to China, plunged into the study of military science. He devoted himself to studying what he had learned, paid close attention to foreign scientific trends, and constantly introduced new scientific research achievements, making great contributions to the national defense cause of the motherland. Known as the "father of missiles", he was awarded the honorary title of "National Model Worker" by the State Council.

How many people dream of living in America and being hired as tenured professors. But for the sake of the prosperity of the motherland, Qian Xuesen put all this down. Today, when the economic tide hits the society like a scourge, Qian Xuesen's patriotic words and deeds undoubtedly condense the soul of the Chinese nation and show the shocking power of patriotism to people with lofty ideals.

Qian Xuesen's patriotic story (3);

Father-in-law Jiang Baili

Qian Xuesen said before that there are two people who have the greatest influence on him in this life, one is the founding Prime Minister Zhou Enlai and the other is his father-in-law Jiang Baili.

Jiang Baili studied in the Japanese NCO School before, and was known as "the father of modern military science". Some people say that he defeated the Japanese twice before. At the graduation ceremony of the Japanese NCO School, Jiang Baili beat all his classmates with excellent results, including later Japanese famous soldiers, such as Okamura Ningji, Banyuanzheng Shiro and Isoroku Yamamoto.

Jiang Baili was awarded the Cherry Blossom Festival, the highest honor of the Japanese army, by Emperor Hirohito. 1937 In the early days of the Anti-Japanese War, Mr. Jiang Baili's On National Defense first put forward the viewpoint of a lasting war of resistance. After Japan's defeat, many Japanese officers were surprised to find that the Japanese imperial army almost honestly obeyed Jiang Baili's command, marched from east to west, and then was trapped in the battlefield in western Hunan, and finally ended in failure.

Jiang Baili did two influential things for Qian Xuesen, one was marriage, and the other was major selection.

Jiang Baili and Qian Xuesen's father, Qian, are best friends. Before studying in Japan, Jiang Baili married a Japanese woman and gave birth to five daughters. He knew that Qian Xuesen was the only son of the Qian family and was unmarried, so he planned to marry his third daughter, Jiang Ying. Under the arrangement of parents, Qian Xuesen and Jiang Ying soon developed feelings. From 65438 to 0935, Qian Xuesen went to study in the United States, and Jiang Ying also went to study in Europe. Although it is far from Wan Li, we still exchange letters, and our feelings are getting deeper and deeper. It was not until 1947 that Qian Xuesen returned to Shanghai and married Jiang Ying. After the marriage, the husband and wife returned to the United States together and had a good relationship. In the days when they were imprisoned and persecuted by the United States, the two always stood together and supported each other.

Before Qian Xuesen went to study in the United States, his father Qian Jun was very opposed to his son's choice of aviation science major. Qian Jun believes that the foundation of China's aerospace industry is very backward, and the urgent task is to develop good aircraft. However, Qian Xuesen insisted that China's aircraft manufacturing technology lags far behind the West, and only by developing on the basis of aviation theory can it fundamentally catch up with the West. Both father and son insisted on their own views and even had an argument.

Mr. Jiang Baili heard about the fight between Qian and his son, and went to be a peacemaker. He carefully introduced the development of aviation industry in the west to Qian, telling him that aviation industry is an industry combining theory with engineering practice, and engineering practice should follow theory. Without theory, any practice is empty talk. Jiang Baili's words made money suddenly enlightened, and money finally prevented his son from learning aviation theory.

When Qian Xuesen recalled the past, he thanked his father-in-law for his persuasion and Jiang Baili for giving his daughter and a good wife.

Qian Xuesen's patriotic story (4);

Qian Xuesen's life can be described as stormy. He was born in the era of China's domestic troubles and foreign invasion, and he was at the mercy of others. He is the son-in-law of Jiang Baili, a famous Chinese military scientist. In order to save the endangered motherland, Qian Xuesen first went to the United States to study for knowledge, but was forcibly detained by the United States after returning home. After traveling abroad for several years, he finally returned to the embrace of the motherland and devoted himself to the construction of the motherland. He made great contributions to the development of missile and aviation science in China during World War II.

Goodbye, my dear motherland.

China in the late Qing Dynasty was the darkest time for the Chinese nation for 5,000 years. When the powers carved up China, China embarked on a humiliating journey. Personality is the period of Sino-Japanese War and Eight-Nation Alliance, when the Boxer Rebellion broke out. This campaign made those unequal treaties fall on the shoulders of the people of China again, increased the burden on the people of China, and plunged China into a semi-colonial and semi-feudal society.

19110 On June 010, the Revolutionary Party launched an armed uprising in Wuchang, destroying the Qing government, opening the national revolution in China and establishing the first bourgeois republic in Asia. Qian Xuesen was born in Shanghai two months after Wuchang Uprising.

At that time, China was at home and abroad. War raged in China, and the great powers set off a frenzy to carve up China. Domestic warlords scuffled, and the people were miserable. Qian Xuesen spent his childhood in such a background. When Qian Xuesen was young, he realized that China was poor and weak. He is determined to change the status quo of China and embark on a road to fame that belongs to China people.

1September 1923, Qian Xuesen 12 years old. He entered the middle school affiliated to Beijing Normal University and was admitted to department of mechanical engineering of Shanghai Jiaotong University six years later. 1934, Qian Xuesen obtained the qualification of the second publicly-funded international student in Tsinghua University in the United States. 1In August, 935, Qian Xuesen left the turbulent motherland on an American mail boat in Shanghai, looking at the Huangpu River in the distance, and white waves rolled. Qian Xuesen is full of thoughts. He silently said to himself, "Goodbye, my dear motherland, now you are in power. I'm going to the other side of the ocean to learn the most advanced science and technology, so that you can revive in the East as soon as possible! "

In September of the same year, Qian Xuesen went to the United States and successfully entered the Aviation Department of MIT.

Qian Xuesen's patriotic story (5);

It is easier to go abroad than to return home.

1May 20th, 9491May 4th, 949, Professor Ge Tingsui and Professor Cao Richang, leaders of China Association of Scientists Studying in the United States, wrote letters to persuade Qian Xuesen to return to China to participate in the post-war construction of the motherland. On June 65438+1 October1of the same year, the news of the founding of New China reached the other side of the ocean. Qian Xuesen made up his mind and vowed to return to his dream motherland.

1in July, 950, Qian Xuesen prepared to bring 800 kilograms of books and scientific research notes back to China, but was forcibly detained by the US immigration authorities, and all the materials and books were seized. Qian Xuesen participated in many secret scientific research institutions in the United States. Wherever he goes, he is worth five infantry divisions. I would rather kill this guy than let him go back to China! "

The news that Qian Xuesen was forcibly detained in the United States was sent back to China, which shocked the whole country. Many domestic scientists expressed their solidarity with Qian Xuesen and condemned the US government for being too extreme. The New China publicly accused the United States of forcibly detaining Qian Xuesen against its will, which was totally inconsistent with the so-called slogans of human rights, democracy and freedom in the United States.

China has been trying to get Qian Xuesen back to China as soon as possible. At the zhina Peace Restoration Conference, Premier Zhou Enlai said that China could release 1 1 senior American generals captured on the Korean battlefield, and China would first release four American ace pilots as a sign of sincerity. However, the United States insisted on not giving in, claiming that there was no evidence to prove that Qian Xuesen was going back to China.

When the negotiations were exhausted, Chen Shutong, vice chairman of the National People's Congress Standing Committee (NPCSC), suddenly received a letter from Qian Xuesen. The message in the letter is to ask the motherland to help him return to China. It turned out that Qian Xuesen saw Chen Shutong in Tiananmen Square through an American newspaper, and Chen Shutong was his father's good friend, so he decided to write to him. Qian Xuesen first got rid of the surveillance of American spies, and left this letter to Chen Shutong in the interlayer of the letter to his relatives in Belgium.

After receiving the letter, Chen Shutong immediately handed it over to Premier Zhou Enlai. Premier Zhou used this as conclusive evidence that the American authorities detained Qian Xuesen, so the United States had to let Mr. Qian Xuesen return to China in the name of "expelling prisoners." 1955 September 17, Mr. Qian Xuesen finally got what he wanted and took his wife and a pair of young children on the road to return home. On October 8th, 65438/KLOC-0, Mr. Qian Xuesen finally returned to China.

However, Qian Xuesen was extremely disgusted with the US government's sending him back to China in the name of expelling criminals. He insisted that if the United States didn't apologize for it, he would never go to the United States again. Sure enough, in Qian Xuesen's life after returning to China, he never went to the United States again.

Qian Xuesen's patriotic story (6);

Studied in America for many years

1September, 935, Qian Xuesen entered the Massachusetts Institute of Technology, and his academic performance has been among the best. During his internship after graduation, Qian Xuesen fully felt the bitterness of being a weak national. At that time, China was poor and weak for more than 100 years, China people went abroad to study, which was extremely despised by the European and American powers, and China people were discriminated against by Americans.

1936 10, Qian Xuesen entered the California Institute of Technology and became a proud disciple of the Hungarian-American scientist von Carmen. Teachers and students have run into each other in the long-term teaching process and scientific research, leaving a profound friendship. At that time, Mr. von Carmen was a top scientist in the emerging field of aviation science and a professor of dynamics. Feng Carmen, who met Qian Xuesen for the first time, was full of praise for this solemn young man. He asked a lot of questions, but all of them were answered by Qian Xuesen. He reacted quickly. In the following years, Qian Xuesen successively obtained a doctor's degree in mathematics, a master's degree in aviation engineering and a doctor's degree in aviation, and became one of the main members of the rocket research group of Guggenheim Aviation Laboratory.

In the early 1940s, Qian Xuesen and another aviation scientist, Marina, jointly published an important long-range rocket research report, summary and preliminary analysis, which became the theoretical basis for the development of surface-to-surface missiles and sounding rockets in the United States. In addition, Qian Xuesen also participated in the "Al-Haraman Plan" for the development of US nuclear weapons.

From 1945 to 1947, after the end of World War II, civil liberation wars were also won one after another. Mr. Qian Xuesen realized that national liberation and rejuvenation were imminent and decided to return to China to devote himself to the construction of the motherland. However, the journey back to China was indeed unimaginable bumpy and difficult.

1950, the United States disqualified Qian Xuesen from participating in secret research institutions because he was suspected to be party member. Qian Xuesen took this opportunity to return to his long-lost motherland on the grounds of returning home to visit relatives. Just as he was about to leave, he was detained by the American immigration authorities. Fortunately, he was released on bail by his colleagues at 15000 USD. However, since then, the United States has repeatedly prevented him from returning to China, and Qian Xuesen was detained and persecuted by the US authorities for five years.

According to Qian Xuesen's account in his later years, during his five years in the United States, he never forgot to go back to China and prepare luggage every day. Due to the deliberate suppression by the American government, the living conditions at home are very poor and we have to move frequently. Fortunately, his wife, Jiang Ying, is very virtuous and soothes his lonely and helpless heart. His wife, Jiang Ying, decisively fired all the maids in the family and took on all the housework alone.

During these five years, Mr. Qian Xuesen did not give up his plan to return to China. He used to be an associate professor at California College, and after teaching, he did not forget to continue his academic research. 1953 published the article "take off from the orbit of the earth satellite", 1954 "engineering cybernetics" caused a sensation in the industry.

Qian Xuesen's patriotic story (7);

Scientific research madman

Qian Xuesen, who returned to the motherland, began the most glorious course of his life. He can't wait to devote himself to the aviation and national defense construction of the motherland.

/kloc-in the winter of 0/955, Qian Xuesen visited Harbin Institute of Military Engineering under the leadership of General Chen Geng. During the conversation, Qian Xuesen insisted on developing China people's own missiles and rockets. During the period of 1956, Qian Xuesen put forward "Opinions on Establishing China's National Defense Aviation Industry", and elaborated the development and construction planning of China's missile and rocket projects in detail. This opinion immediately received great attention from the CPC Central Committee.

In the same year, Chairman Mao met with Qian Xuesen in Zhongnanhai. Qian Xuesen was deeply impressed by Chairman Mao's kindness, kindness and approachability. With the support of the National Government, Qian Xuesen later established the first fire in China.

The Fifth Research Institute of the Ministry of National Defense, Arrow and Missile Research Institute. Research Therefore, Qian Xuesen worked for many scientific researches.

The best among scholars, in order to let these scholars who have never been exposed to missiles integrate into the construction and development of missiles and rockets as soon as possible, Qian Xuesen first told the college students and professors of 156 about the introduction of missiles, and personally made a study plan for aerodynamics, engines and other related majors.

In the 1960s, Sino-Soviet relations deteriorated rapidly. The Soviet Union withdrew all scientists who assisted China, and at the same time tore up all contracts supporting industrial projects in China. Under such extremely difficult conditions, Qian Xuesen, like many scholars, ate coarse grains and slept in tents. They share joys and sorrows. Although foreign technology was blocked, Qian Xuesen's team was able to overcome many difficulties. Finally, on June 5th, 1960, 165438, China launched its first missile. This time is only 17 days before the Soviet Union withdraws its scientific experts. Marshal Nie Rongzhen was very excited at Jiuquan launch site at that time. He said, "This is a turning point in the history of China's military equipment!" 1964 65438+1October 16, the first atomic bomb developed by China was successfully tested and exploded. Two years later, on June 27th, 10, the test explosion experiment of China's medium-and short-range surface-to-surface missiles carrying nuclear warheads and the practice of China's combination of atomic bombs and missiles were completed, which made China's national defense force reach the top position in the world and shocked the world.

1965, Qian Xuesen suggested to the State Council, China to build an artificial satellite in China. 1970, the successful launch of China's first artificial satellite "Dongfanghong" marks the development of China's space industry to a higher level.

Qian Xuesen is not only the hero of China's aviation technology and missile rocket technology, but also the founder of China's high-end military technology. From 65438 to 0998, Qian Xuesen made a systematic exposition on military science. He said: "Military science is the basic theory of military science and technology, military operational research is the technical theory, and technical application is the engineering theory of military systems."

Qian Xuesen's patriotic story (8):

China people, China heart, Qian Xuesen's patriotism.

Qian Xuesen's life is brilliant. As a patriot, it took him five years to break through layers of resistance and return to China. As a scientist, he has made great contributions to the development of science and technology in China when the new China is poor. Qian Xuesen said that there were three most exciting moments in his life. The first time he learned that the United States would finally let him return to China, the second time he learned that he would join the ranks of proletarian intellectuals such as Jiao and Meng Tai. The third time was on the 10th anniversary of the founding of the People's Republic of China, and he gloriously joined the China Producers' Party.

Numerous scientists have made contributions from the birth to the growth of New China, but Qian Xuesen is the most brilliant, outstanding and influential figure. So, what contribution did Qian Xuesen make in his life?

During the Sino-Japanese War of 1894-1895, Qian Xuesen realized that China's aviation strength was too weak, so he decided to study the theoretical knowledge of aviation technology in the United States. Persecuted by the authorities in the United States, he stayed in the United States for five years and never gave up the opportunity to return to his motherland. He made an immortal contribution to the victory of World War II. He completed the aerodynamic research with von Carmen before, leaving a formula of "Carmen's money approximation". Even von Carmen's tutor said that this disciple's academic knowledge has surpassed himself.

During his tenure as the first president of the Fifth Research Institute of the Ministry of National Defense, he applied his rich knowledge in the fields of power, guidance, aerodynamics, structure, materials, computers, quality control and scientific and technological management to the research and development of missiles, rockets and satellites. He also presided over and successfully completed the "establishment of jet and rocket technology", and he also participated in the development of short-range missiles, medium-and short-range missiles and China's first artificial earth satellite.

Qian Xuesen is recognized as the pioneer of world aviation technology, the founder of important technology and the originator of control engineering. He is a leader in applied mathematics and applied mechanics, and has made creative contributions in aerodynamics, aviation engineering, jet propulsion, engineering cybernetics, physical mechanics and other fields.

Qian Xuesen left immortal academic works, such as Engineering Cybernetics, On System Engineering, Introduction to Interstellar Navigation, etc. These works have successively won the first prize of Natural Science Award of China Academy of Sciences, the special prize of National Science and Technology Progress Award, the Little Rockwell Medal and the title of world-class science and engineering celebrity.

Qian Xuesen has devoted more than 40 years to the scientific and technological development of missiles, aviation and rockets in China, and has the honorary titles of the father of missiles in China, the king of rockets and the father of China Airlines. On June19911KLOC-0/6, the State Council and the Central Military Commission awarded him the honorary title of "National Outstanding Contribution Scientist" and the first-class hero model medal. Subsequently, Qian Xuesen served as honorary chairman of the Chinese Scientists Association. 1September 1999 18, the Central Committee, the State Council and the Central Military Commission awarded him the medal of "Two Bombs and One Satellite".

Qian Xuesen was indifferent to fame and fortune all his life, and he had lofty personality quality. In the years when he struggled for the scientific research experiment of the motherland, he always continued the lofty spirit that a patriotic scholar should have. Qian Xuesen once said, "I am a scientist in China. The science and technology I have learned only serve my motherland, and the purpose of my life is to serve all the people of China. If I want something, the highest reward I want is the satisfaction of the people of the whole country with my work. "

In his later years, Qian Xuesen still always paid attention to national security. He came out of the era of poverty and weakness in China. He had witnessed the situation that the motherland was divided up by foreign powers before, and he never wanted China to have such a situation again. Therefore, in his later years, Qian Xuesen still cared about the construction of national defense science and technology and the modernization of the army.

When Qian Xuesen was hospitalized due to illness, senior cadres of the party and the state visited him in front of the hospital bed. Qian Xuesen clasped the hands of leading comrades of the Central Military Commission and asked them to develop high-end military technology in China. Subsequently, the Propaganda Department of the Central Committee, the Organization Department of the Central Committee, the Literature Research Office of the Central Committee, and1kloc-0/senior departments of the Party and the State jointly organized the selection of 100 hero model figures who have made outstanding contributions to the founding of New China and 100 figures who have touched China since the founding of New China. Qian Xuesen was named as "touching China". This fully reflects Qian Lao's position in the eyes of China people, and it is also the affirmation of all China people for Qian Xuesen's brilliant achievements in his life!

In 2009, People's Republic of China (PRC)'s 60th birthday military parade shocked the world. Qian Xuesen finished his life on June 365438+ 10 of that year at the age of 98. Although people are dead, the hero's soul is always there, and Qian Xuesen's position in the eyes of China people will never waver.
