Professor Tsinghua University talks about immigrating to the United States

19551kloc-0/on October 8th, Qian Xuesen finally set foot on the land of the motherland after 20 days of wandering. A year later, 1956 10 10, the first rocket and missile research institution in new China? The fifth research institute of the Ministry of National Defense? It was formally established, with Qian Xuesen as its president, and officially started China's space industry.

Excellent grades, studying in the United States at public expense, setting up a jet propulsion laboratory.

From 65438 to 0929, Qian Xuesen studied in department of mechanical engineering, national chiao tung university. 1934 After graduation, Qian Xuesen took the exam for students studying in the United States at Geng, Tsinghua University, and successfully became one of 20 students studying in the United States at public expense. At the suggestion of Wang Shichuo, a professor of aerodynamics in Tsinghua University, Qian Xuesen decided to study aerodynamics at MIT.

1September 1935, Qian Xuesen and others 19 overseas students went to the United States by boat, 1936 successfully graduated with a master's degree from Massachusetts Institute of Technology. Later, he went to California Institute of Technology for further study, and studied under the authority of aerodynamics Feng? Professor Carmen. From 1938 to 194 1, Qian Xuesen and his mentor Feng? Carmen published many important papers on aerodynamics, participated in wind tunnel development, invented the famous Qian-Carmen formula in academic circles, and participated in the development of solid rockets at California Institute of Technology.

1943, the US military intelligence department learned that Germany was building a large rocket base, and immediately funded the establishment of the now famous jet propulsion laboratory at California Institute of Technology. Qian Xuesen, one of the founders, officially became the head of the Jet research group. Today, the Jet Propulsion Laboratory has become an important part of NASA, and has been responsible for the research and development of major space exploration projects such as Curiosity Rover and Jupiter probe for many times. In July this year, the United States "Tenacity" rover launched at the same time as China's "Tian Wen No.1" also came from the Jet Propulsion Laboratory.

1944, Qian Xuesen was hired by the U.S. Department of Defense as an air force consultant, and constructed a blueprint for American space research in the next 20 years. Later, he joined the scientific advisory group of the US Department of Defense. 1945, Qian Xuesen and Feng? Carmen went to Germany together and asked German rocket scientists. Among them, Qian Xuesen personally asked questions and recruited Feng, the father of American space flight and the developer of Saturn V, the rocket that landed on the moon. 1949, Qian Xuesen was officially promoted to full professor at MIT and designed the famous? Qian Xuesen's track? .

After being detained for five years, he can finally return to the embrace of his motherland.

From 65438 to 0950, due to various reasons, Qian Xuesen's research work in the United States was banned by the Federal Bureau of Investigation. Unable to continue his research, Qian Xuesen had the idea and willingness to return to China. The United States is aware of the depth of American secrets mastered by Qian Xuesen's research work and is determined not to let Qian Xuesen return to China. The US Department of Justice and Immigration Bureau began to detain Qian Xuesen. With the help of California Institute of Technology, Qian Xuesen was released on bail, but he was still not allowed to leave the United States and could only engage in some simple basic research.

From 65438 to 0955, after years of struggle and many talks between the Chinese and American governments, Qian Xuesen was finally released by the American government. At this time, the United States believes that Qian Xuesen has not been exposed to confidential research in the United States for nearly five years, and the confidential information he had previously mastered is outdated and useless. In September 17 of the same year, Qian Xuesen finally boarded the ship returning to China.

Are China people shorter than foreigners?

Qian Xuesen, who returned to the motherland, devoted himself to the construction of new China before he had too much rest. From June of 1955 to February of 15, Qian Xuesen visited several scientific research institutes, universities and factories in Beijing and Northeast China, and found out the foundation of establishing China aviation industry. When visiting Harbin Institute of Military Engineering, General Chen Geng, the first president of Harbin Military Industry, asked China if he could develop missiles. Qian Xuesen replied without hesitation:

Why not? What foreigners can do, so can we in China. Are China people shorter than foreigners? ?

Since then, with the support of the Premier, Qian Xuesen has started the research and development of missiles and aerospace in the new China. Under the leadership of Qian Xuesen, the first missile of New China, Dongfeng-1 short-range ballistic missile, was successfully launched in 1960. 1970, China's first artificial satellite, Dongfanghong-1, was successfully launched.

On June 365438+1October 3 1 day, 2009, Qian Xuesen died in Beijing at the age of 98.

With Qian Xuesen's return to China, China's aerospace industry and missile industry have developed rapidly. Today, the 65th anniversary of Qian Xuesen's return to China, China's missile and space undertakings are at the forefront of the world. There are Dongfeng series missiles to defend the country, Chang 'e Jade Rabbit to the moon, Beidou navigation all over the world, and various rockets of the Long March family. All this is inseparable from the solid foundation laid by Qian Xuesen when he returned to China that year.
