Qian Xuesen s celebrity deeds are a few words short

A brief introduction to Qian Xuesen's main deeds is as follows:

Since he was a teenager, Qian Xuesen has loved the motherland and science. Later, he went to the United States to study aerodynamics, and together with his teacher, he proposed the "Carmen Money Formula" and founded engineering cybernetics.

After Qian Xuesen made great achievements in the United States, he wanted to return to China to serve the motherland with his knowledge, but this matter was unfortunately understood by the US federal **, they were afraid that Qian Xuesen would endanger the interests of their country and maliciously detained him. It took a lot of effort for Qian Xuesen to return to the motherland. After returning to the motherland, he used his perseverance to design the first missile for China, the Dongfeng-1.

Qian Xuesen's character achievements

At the beginning of 1956, Qian Xuesen established China's first rocket and missile research institute, the Fifth Research Institute of the Ministry of National Defense, and served as the first president. He presided over the completion of the program "Establishment of Jet and Rocket Technology".

Qian Xuesen participated in the development of short-range missiles, medium- and short-range missiles, and China's first artificial earth satellite, directly led the "two-bomb combination" test of using medium- and short-range missiles to deliver atomic bombs, participated in the formulation of the "two-bomb combination" test of China's short-range missile delivery atomic bomb, participated in the formulation of China's first interstellar aviation development plan, and developed and established engineering cybernetics and systematics.

Under the leadership of Qian Xuesen's efforts, China's first atomic bomb was successfully launched on October 16, 1964, China's first hydrogen bomb was successfully tested on June 17, 1967, and China's first artificial satellite was successfully launched on April 24, 1970.

Qian Xuesen's deeds are summarized as follows:

In 1934, Qian Xuesen graduated from Shanghai Jiaotong University, in order to better serve the motherland, he went to the Massachusetts Institute of Technology in the United States for further study, and in 1936 transferred to the California Institute of Technology to continue his studies. Qian Xuesen studied very hard, and after three years, he received a doctorate and stayed on to teach.

Later, after a lot of hardships, Qian Xuesen finally returned to the embrace of the motherland and made a huge contribution to the research and development of China's "two bombs and one satellite".

Scientific achievements

Qian Xuesen has done pioneering work in many fields of mechanics. He has made many research achievements in aerodynamics, the most prominent of which is to put forward the law of similarity of transonic flow, and together with Carmen, he was the first to put forward the concept of hypersonic flow, which provided a theoretical basis for the aircraft to overcome the thermal barrier and sound barrier in the early stage, and laid an important theoretical foundation for the development of aerodynamics.

The formula used in the design of high subsonic aircraft is the Carmen-Qian Xuesen formula, named after Carmen and Qian Xuesen. In addition, Qian Xuesen and Carmen jointly proposed a new theory of nonlinear instability of spherical and cylindrical shells at the end of the 30s.
