Qian Xuesen’s central idea of ??Chinese pride

Qian Xuesen was born in Shanghai in 1911 and graduated from Shanghai Jiao Tong University in 1934. In order to better serve the motherland, he was admitted to the Massachusetts Institute of Technology in the United States for further study in 1935. In 1936, he transferred to the California Institute of Technology to continue his studies. He became a disciple of the famous aeronautical scientist von Kármán and studied aeronautical engineering theory. Qian Xuesen studied very hard and obtained his doctorate three years later and stayed at the school to teach. Under the guidance of von Kármán, Qian Xuesen developed a strong interest in rocket technology and made rapid progress in the fields of high-speed aerodynamics and jet propulsion research. Soon, on the recommendation of von Kármán, Qian Xuesen became the youngest tenured professor at Caltech.

In the 15 years from 1935 to 1950, Qian Xuesen made great achievements in academics and enjoyed generous treatment in life, but he always missed his motherland.

When the Korean War broke out in 1950, Qian Xuesen’s wish to return to China to serve his motherland came to nothing. Qian Xuesen was persecuted because he was Chinese. It was not until June 1955 that Qian Xuesen wrote to Comrade Chen Shutong, then vice chairman of the Standing Committee of the National People's Congress, requesting the party and government to help him return to the embrace of the motherland as soon as possible. Premier Zhou took the matter very seriously after learning about it and instructed relevant personnel to handle the matter at the appropriate time. After hard work, on October 18, 1955, Qian Xuesen and his family finally returned to their motherland after 20 years of absence. Soon, he was appointed director of the Institute of Mechanics, Chinese Academy of Sciences.

In order to improve our country’s national defense capabilities and protect our country’s security, on October 8, 1956, our country’s first missile research institution, the Fifth Research Institute of the Ministry of National Defense, was established, and Qian Xuesen was appointed as the first Serve as dean. Under the guidance of Qian Xuesen, after hard work, my country's first domestically produced missile was finally successfully manufactured in October 1960.

Qian Xuesen, a famous scientist. One of the founders of modern mechanics in my country. He has made many pioneering contributions in the fields of aerodynamics, aeronautical engineering, jet propulsion, engineering cybernetics, physical mechanics and other technical sciences. He has made outstanding contributions to the creation and development of my country's rocket, missile and aerospace industries, and is an advocate of theoretical and applied research on systems engineering in my country.

Qian Xuesen’s story before returning to China

When the first five-star red flag was slowly raised in Tiananmen Square in 1949, he was the director of the Supersonics Laboratory of the California Institute of Technology and the "Gu Gen" Qian Xuesen, director of the Han Jet Propulsion Research Center, is deeply happy for the new life of his motherland. He plans to return to China and use his expertise to serve New China. But it was not easy for Chinese scientists in the United States to return home at that time, and Qian Xuesen's expertise was directly related to national defense, so he finally returned to the embrace of his motherland after going through many hardships. His tortuous struggle process showed Qian Xuesen's deep love for the motherland at that time, which was very touching.

In mid-September 1950, Qian Xuesen resigned from his position as director of the California Institute of Technology's Supersonic Laboratory and head of the "Guggenheim Jet Propulsion Research Center" and went through the procedures to return to China. He bought a plane ticket from Canada to Hong Kong and handed his luggage to the moving company for shipment.

However, just two days before he planned to leave Los Angeles, he suddenly received a notice from the U.S. Immigration and Naturalization Service - he was not allowed to return to the country! The Immigration Bureau threatened that if you leave the country without permission, you will be fined or even jailed if you are caught!

A few days later, Qian Xuesen was arrested and taken to the U.S. Immigration and Naturalization Service detention center on the charge of "participating in a political party that advocates the use of force to overthrow the U.S. government."

The luggage Qian Xuesen handed over to the moving company was inspected by U.S. Customs and the FBI, and it was said that telegram codes, weapons blueprints, etc. were "discovered" from it. The Immigration and Naturalization Service wanted to "interrogate" Qian Xuesen, saying that Qian Xuesen was a "member of the American Communist Party." Later, it also said that several of the American classmates Qian Xuesen met when he was studying in the United States were members of the American Communist Party. . The Immigration and Naturalization Service threatened that Qian Xuesen had "violated U.S. immigration laws" and would "deport" Qian Xuesen. Not long after he said this, he quickly changed his words. Because Qian Xuesen was to be "deported", which was exactly what Qian Xuesen wanted! In the detention center, Qian Xuesen was imprisoned like a criminal. Qian Xuesen once recalled: "In the 15 days I was detained, I lost 30 pounds. In the detention center, every night, the secret agents would come in and wake you up every hour, so that you could not get any rest, and mentally Trapped in a state of extreme tension.

”

The Immigration and Naturalization Service’s persecution of Qian Xuesen aroused public outrage in the American scientific community. Many friendly people in the United States came to rescue Qian Xuesen and found him a defense lawyer. They raised 15,000 US dollars as a deposit. Release Qian Xuesen from the detention center.

In June 1955, Qian Xuesen wrote to Comrade Chen Shutong, then vice chairman of the Standing Committee of the National People's Congress, asking the party and government to help him return to the embrace of the motherland as soon as possible. After learning about it, the Prime Minister took the matter very seriously and instructed the relevant personnel to handle the matter at the appropriate time. After hard work, on October 18, 1955, Qian Xuesen's family finally returned to their motherland after an absence of 20 years. Director of the Institute of Mechanics of the Academy of Sciences. He cares about the motherland, loves the motherland, has outstanding merits, is open-minded, has a noble spirit, is clean and indifferent to fame and fortune, is approachable, has high moral standards, is rigorous and conscientious, and leads by example.
