Guo Yonghuai is a famous aerodynamicist and applied mathematician in China. China played two founding fathers.
1933, Guo Yonghuai entered the physics department of Peking University. 1938 studied aviation engineering at national southwest associated university. 1939 was admitted to the University of Toronto, Canada. Half a year later, He, Qian Weichang, obtained the master's degree in applied mathematics with excellent results and excellent papers. 194/kloc-0 went to California institute of technology to study the aerodynamic problem "discontinuity of transonic flow" in may. From 65438 to 0945, he obtained his doctorate with this important research achievement.
1946 Guo Yonghuai went to Cornell University and founded the Institute of Aeronautics with Professor Sears. Many achievements have been made in frontier fields such as viscous fluid mechanics and hypersonic aerodynamics.
Guo Yonghuai returned to China from 65438 to 0956, and successively served as deputy director of the Institute of Mechanics of Chinese Academy of Sciences, adjunct professor of Tsinghua University, director of the Department of Chemical Physics of China University of Science and Technology, vice president of the Institute of Nuclear Weapons of the Second Machinery Department, and deputy head of the preparatory group of the Aerodynamic Research Institute of the Commission of Science, Technology and Industry for National Defense.
1960 Guo Yonghuai participated in China's nuclear weapons research, and served as the vice president of the No.9 Hospital of the Second Machinery Department. 196 1 served as the chairman of the off-site test Committee of the first atomic bomb explosion physical test. A lot of research work has been done on weaponization and serialization of nuclear bombs. It has made great contributions to the structural design of hydrogen bombs and the related tests of flight trajectory aerodynamics.
1968 12.5, Guo Yonghuai returned to Beijing after attending preparations for the launch of China's first thermonuclear missile. His civil aviation flight crashed and was killed. 12 18, the Ministry of Internal Affairs of the People's Republic of China awarded him the title of martyr. 1999, the Central Committee and the State Council posthumously awarded him the "Two Bombs and One Satellite Meritorious Medal".
Mr. Guo is mainly engaged in theoretical and analytical work abroad. He is very strict with himself, and the topics he chooses are all international issues. He took the bull by the horns, persisted in the analysis to the end and reached an important conclusion. These jobs have made him famous in foreign academic circles. Because of this, people often regard him as a pure theorist. To my surprise, he also attached great importance to new technology and experimental work, which brought new technology and experimental means to the newly established Institute of Mechanics of Chinese Academy of Sciences. This includes at least the shock tube technology and plasma dynamics, which appeared soon in the world at that time. Later, I learned that before preparing to return to China, Mr. Guo specially inspected the new technologies and new fields that he thought China needed for scientific development.
Strictly speaking, Mr. Qian and Mr. Guo are both "theorists" who use applied mathematics as their main tools. Theorists mentioned here refer to those who are mainly engaged in theoretical research, but at the same time have a deep understanding of the actual background of their own theoretical research, a clear understanding of the reality and possible application of theoretical research, and a full understanding of the mutual cooperation of experimental research in theoretical research. Therefore, the two gentlemen have extraordinary broad horizons and long-term strategic thinking. Teacher Guo once asked me face to face whether the person leading a research institute should have theoretical opinions (a good scientist who focuses on experiments can also have high theoretical opinions) or someone else. My answer is the former. He was satisfied then. I think this is because if scientific research lacks high-level theoretical guidance, theoretical research or experimental research, it will lose its direction and fall to the point of following others, making it difficult to innovate.

1955, Qian Xuesen sent two letters inviting Guo Yonghuai to return home. Guo Yonghuai resolutely gave up the superior conditions and treatment abroad and returned to the motherland with his wife Li Pei on 1956 1 1. "As an ordinary science and technology worker in New China, I only hope that my motherland will become stronger one day earlier and will no longer be bullied." Guo Yonghuai said.
1960 in July, the Soviet government informed the government of China that it decided to withdraw all experts from China's nuclear industry system, and then stopped supplying all technical equipment and materials. China decided to develop its own nuclear weapons, and Guo Yonghuai served as the vice president of the Ninth Academy. At that time, the primary task of the Ninth Hospital was to quickly master the structural principle and carry out theoretical exploration and development without drawings and data.
1963, he and his research team moved to the newly-built base in Qinghai. Under the initiative and guidance of Guo Yonghuai, China's first scientific plan on explosive mechanics was quickly formulated, which made mechanics embark on the road of combining with nuclear weapons testing. At the same time, Guo Yonghuai is also responsible for guiding the research on underwater explosion mechanics and water tunnel mechanics of anti-submarine nuclear weapons. In the use of detonation mode of nuclear devices, he proposed "strive for high and low preparation, and take advanced implosion mode as the main research direction". In order to establish the structural design of nuclear weapon device, Guo Yonghuai put forward the method of "two ways go hand in hand, and finally choose the best", and determined the best scheme for the first explosion, which played a decisive role in solving some key problems. This scheme is not only used for the development and explosion of the first bomb, but also for the development and explosion of the whole first generation nuclear weapons.
Guo Yonghuai rushed to the scene early in the morning every day to understand the progress of assembly work and the results of system joint test. Once problems were found, they were studied and dealt with in time. In the days when we are about to enter the formal experimental stage, Guo Yonghuai will be busy for more than ten hours every day, sometimes staying up all night, eating on the floor while sitting and studying. 19641June 16, China's first device explosion test was a complete success196610/October 27th, China's first surface-to-surface missile with a nuclear warhead exploded successfully,197. When the flashing fireball and mushroom-shaped smoke cloud Ran Ran rose, all the testers were boiling, except Guo Yonghuai, who collapsed at the test site, and the staff around him put him on the iron bed in the temporary tent. Guo Yonghuai is too tired.
1963, the expedition team moved to Qinghai base at an altitude of more than 3,000 meters. The climate here is changeable, the winter wind is chilly, sand and stones are often flying, the lowest temperature is MINUS 40 degrees Celsius, and cotton-padded clothes are worn for nine months in a year. He and many colleagues have altitude sickness. In order to study the new situation in time, Guo Yonghuai frequently travels between Beijing and the base. Someone advised him to run less, and he completely ignored his work.
1In September, 965, the development of China's first artificial satellite was started again, and Guo Yonghuai was appointed to participate in the organization and leadership of the development of "Dongfanghong" satellite and recoverable satellite. 196865438+In early February, he found an important data in Qinghai base, and was anxious to go back to Beijing for research, so he took a night flight. He rushed to Lanzhou from Qinghai base and listened carefully to the report of the research group during the transition flight in Lanzhou. In the early morning of February 5, 65438, the plane flew to Beijing Airport. When it was about 400 meters from the ground, it suddenly lost its balance, deviated from the runway, plunged into the cornfield and ignited a fireball. When people searched for Guo Yonghuai from the wreckage, they were surprised to find his body hugging the guards. After the charred two bodies were separated, a briefcase containing top secret documents fell out of the middle, but it was intact. He used his body to protect the information that was extremely important for China's scientific research.
On the 22nd day after Guo Yonghuai's death, China successfully conducted its first thermonuclear missile test. Less than two years after his death,1April 24, 970, China's first artificial satellite was successfully launched. 196865438+On February 25th, People's Republic of China (PRC) and the Ministry of Internal Affairs of the People's Republic of China awarded Guo Yonghuai the title of martyr. 1999 was posthumously awarded the "two bombs and one satellite" medal. He was the only scientist who was posthumously awarded the "two bombs and one satellite" medal and was a martyr.

1909 On April 4th, Guo Yonghuai was born in guo jia cun, Xitan, Rongcheng County. 1929 entered Nankai university preparatory course. 193 1 in July, he was promoted to the physics department of Nankai University. 1933 ~ 1935 studied in the physics department of Peking University. After the outbreak of War of Resistance against Japanese Aggression, he transferred to Kunming and The National SouthWest Associated University for work-study programs. The national disaster has strengthened Guo Yonghuai's belief in saving the country through science. He believes that to make the country strong, we must first develop military science and technology and aviation. To this end, he gave up his long-cherished wish to specialize in optics and changed to aviation engineering.
From September 65438 to September 0940, Guo Yonghuai went to the University of Toronto and studied under Professor J.L. Singh. His master's thesis was completed in just over half a year. His excellent works were praised by his tutor. 194 1 in may, Guo Yonghuai came to the aviation department of California institute of technology to study the discontinuous solution of transonic flow under the guidance of the famous mechanic von Carmen, and obtained his doctorate with excellent results. During this period, China people who worked and studied in the Aviation Department of California Institute of Technology included Qian Xuesen, Lin Jiaqiao and Qian Weichang.
From 65438 to 0946, Guo Yonghuai was employed by Cornell University. The following year 10 was the golden age of his scientific research, and he made in-depth research on transonic theory and viscous flow, which made important contributions to the breakthrough of sound barrier for mankind. At the same time, he developed the deformation parameters and deformation coordinate method of Poincare and Lighthill. Therefore, Qian Xuesen named this method PLK method in 1956. Guo Yonghuai is famous for his achievements in transonic and applied mathematics. /kloc-0 was promoted to tenured professor of Cornell University in July, 955.
Guo Yonghuai crossed the ocean with the hope of saving the country through science. When he was hired by Cornell University, he said to the school: "I came to your school temporarily and will leave at an appropriate time in the future"; Fill in "No" in the form of whether to apply for access to confidential information; Ignore all letters asking him to apply for American citizenship. He seldom participated in social activities, but on the eve of the founding of New China, he joined the Cornell Branch of the China Association of Scientists Studying in the United States and often had a heated discussion with you about the future of the motherland.
1956 165438+10, Guo Yonghuai resolutely gave up superior material conditions and returned to the motherland after16.
After returning home, Guo Yonghuai focused on organizing and leading domestic mechanical and national defense research. He has been a member of the Department of Mathematical and Physical Chemistry of China Academy of Sciences, deputy director of the Institute of Mechanics, head teacher of the engineering mechanics research class jointly organized by the Institute of Mechanics and Tsinghua University, vice president of the Ninth Institute of Mechanical Engineering, and head of the Department of Chemical Physics of China University of Science and Technology. Participate in formulating the development plan of mechanics discipline in China, and advocate the research of emerging mechanics disciplines. He has made great contributions to China's national defense industry and participated in many major projects and projects. He also participated in organizing and leading the design of artificial satellites and the development of surface-to-air missiles of China Academy of Sciences.
He has always been serious about his studies. From 65438 to 0957, with the approval of the State Council, the Ministry of Higher Education cooperated with China Academy of Sciences to set up a research class on engineering mechanics in Tsinghua University, which was held for three times with more than 300 students. They became the first batch of mechanical research and teaching backbones in China. Guo Yonghuai and Qian Weichang organized and led leadership seminars. Guo Yonghuai was also the head teacher of 1958 and 1959, and personally taught the introduction to fluid mechanics. Zhang (the first student of Tsinghua University Engineering Mechanics Research Class, academician of Chinese Academy of Sciences) recalled: "Mr. Guo Yonghuai, who is polite, is very serious about mechanical work. He even paid attention to whether supersonic speed was translated into supersonic speed or supersonic speed, and why Euler's name was translated into Euler. He advocated reading classic works, saying that this era of Pelant was a bumper harvest period of fluid mechanics. Pelant himself is a great authority with profound knowledge and experience, and his writing is comprehensive and profound. He should learn from his Introduction to Fluid Mechanics. "
