Qian Xuesen, born on December 11, 1911, died in 2009, a world-renowned scientist, aerodynamicist, the founder of China's manned spaceflight, the winner of the Meritorious Service Medal of two bombs and one star, and is known as the "father of China's aerospace" and "the father of China's missiles". There is no doubt that Qian Xuesen is the pride of the Chinese people, and today I will briefly introduce to you this famous meritorious scientist.
Qian Xuesen, a native of Zhejiang Province, was born in Shanghai, and his life experience can be divided into four parts: before going abroad, his years in the United States, his time in detention and his return to China. When Qian Xuesen planned to return to China in 1950, U.S. Navy Vice Admiral Danny Kimble said that Qian Xuesen was worth five divisions no matter where he went, but in fact, for China, Qian Xuesen was far more important than five divisions.
Qian Xuesen entered the High School Affiliated to Peking University at the age of twelve, and five years later he was admitted to the Railway Engineering Department of the School of Mechanical Engineering of the Shanghai School of the Ministry of Railways Jiaotong University, and graduated from the National Jiaotong University in 1934. This is Qian Xuesen's main experience before going abroad, but during this period, the most important thing for Qian Xuesen is to determine his relationship with his sister Jiang Ying.
Qian Xuesen's father Qian Junfu and Jiang Baili are good friends, the Qian family has a Qian Xuesen, and Jiang Baili has five daughters, so Jiang Baili passed the third daughter Jiang Ying to the Qian family, originally a daughter, but I didn't expect to achieve a good marriage, Qian Xuesen and Jiang Ying looked at each other well, and the daughter became a daughter-in-law, after Qian Xuesen studied in the United States, Jiang Ying also went to Berlin, Germany with his father, and the two exchanged letters, and the relationship was not cooled down because of geographical isolation, but became more enthusiastic, and later Jiang Ying went to the United States, has always accompanied Qian Xuesen.
While studying in the United States, Qian Xuesen first studied in the Department of Aeronautics at the Massachusetts Institute of Technology, obtained a master's degree in 1936, and then became the most important student of von Kármán under the tutelage of the famous scientist von Kármen. In the United States, Qian Xuesen is mainly engaged in research in the fields of aerodynamics, solid mechanics, rockets, and missiles, and has achieved considerable results. During this period, Qian Xuesen encountered a very important turning point, that is, he wanted to engage in aviation, and his father Qian Junfu wanted him to engage in aircraft manufacturing, and his father's lack of support made Qian Xuesen very distressed. Later, Qian Xuesen recalled that there were two people who had the greatest influence on him in this life, one was Prime Minister ***, and the other was his father-in-law Jiang Baili.
After Qian Xuesen's academic success, he successively served as a professor at the California Institute of Technology and the Massachusetts Institute of Technology, and married his sister Jiang Ying while serving as a professor at the Massachusetts Institute of Technology in 1947, completing the long-distance love run. By the founding of New China in 1949, before Qian Xuesen planned to return to China in 1950, the life of the two of them was still very good, but in 1950, Qian Xuesen planned to return to China, and was detained by the United States, not only revoked his qualification to participate in classified research, but also directly imprisoned, Qian Xuesen lost his freedom, and he lost nearly 30 pounds in a month. He was detained on the island of Termina for 14 days until Caltech sent 1He was released on $50,000 bail, but release does not mean that he can return home.
During this period, he wrote a letter to his father's old friend Chen Shutong, hoping that the motherland would help him return to China, and the time of writing the letter was 1954, from the moment he wanted to return to China, it had been four years, and at the Geneva Conference of the same year, China and the United States discussed many times and made many concessions in order to allow Qian Xuesen and many other students in the United States to return to China. During the period of detention in the United States, the life of Qian Xuesen and his wife was very difficult, Jiang Ying was originally a beautiful girl, but life made her have to dismiss the maid, take care of all the housework, take care of Qian Xuesen, and return to China in 1955, Qian Xuesen and his wife had a son and a daughter, Qian Xuesen completed the work "Engineering Cybernetics" in this most difficult time.
Still. After returning to China, Qian Xuesen participated in the research work of missiles and aeronautical engineering, how much contribution has been made, there are many lists, so it is not listed, he is known as the "father of Chinese missiles" and "the father of China's aerospace", and is known as the first to go to the first five divisions, but for China, his value exceeds five divisions, this is the evaluation of him, after returning to China, his wife Jiang Ying also served as a technical director in the experimental opera house, and toured in the northwest and other places many times.
