Qian Xuesen: Why can't the Chinese?2019-04-25 21:30:50 526 ℃
China's aerospace industry has developed from scratch, from weak to strong, from following to running side by side, even leading in some fields. It is moving from a big Aerospace country to a powerful aerospace country. It is inseparable from the wisdom and ability of the working people of China and the solid foundation laid by the older generation of astronauts represented by Qian Xuesen. When Qian Xuesen returned to China in the 1950s, the state was uncertain about whether to launch an aircraft or a missile first. After careful investigation, Qian Xuesen said that, on the basis of current economic and national defense, missile development should be carried out first. And then there was Qian Xuesen's classic answer to General Chen Geng's question: "Why can't the Chinese do that?" Can't the Chinese do what foreigners can do? Chinese are shorter than them? In the early days of the founding of New China, the success of the "two bombs" directly promoted the rapid development of China's space industry, enabling China to stand among the nations of the world, fully demonstrating the important role played by Qian Xuesen as a scientist with strategic vision.
Aerospace is a large-scale scientific and technological system engineering, which requires multi-field and multi-level organic integration and collaboration to form an integrated innovation system. How to organize tens of thousands of people to obtain reliable products with the lowest consumption in the shortest time requires a scientific method of organization and management. For this reason, Qian Xuesen put forward a system engineering management method that has been used in China's aerospace industry since its inception, that is, the mode of one general headquarters and two command lines. Qian Xuesen's contribution has laid a key position as the leader of scientific research and organizational management in the process of the establishment and development of China's aerospace industry.
China's space industry has come to this day, Qian Xuesen has played a supporting role in providing advice and suggestions. He also established profound revolutionary friendship with Premier Zhou Enlai and Marshal Nie Rongzhen.
Remember that during a launch test of Dongfeng missile, technicians found that the missile body was deformed and reported it immediately. Qian Xuesen observed that this is due to improper method of filling liquid fuel, resulting in imbalance of internal and external pressure. He judged from his own experience that the launch would not be affected, but the then commander of the base dared not sign it, so he reported the issue to Marshal Nie Rongzhen. "Strong" Nie Rongzhen answered firmly: "We said that technical problems should be listened to by Qian Xuesen, Qian Xuesen agreed to launch, I agreed to launch. Finally, the missile was launched successfully and the test was successful. In October 1991, Qian Xuesen was awarded the honorary title of "National Outstanding Contribution Scientist" and the medal of "First Class Hero Model". Qian Xuesen admitted that he was not very excited about the award because there had been two exciting moments before: once when he became a glorious Communist Party member; the other time when the Organizational Department of the Central Committee of the Communist Party of China elected five representatives of Lei Feng, Jiao Yulu, Wang Jinxi, Shi Laihe and Qian Xuesen as excellent Communist Party members in the past 40 years of liberation, which is also true. He was very excited because he felt that he was a member of the working people.
For young people in the space field, Qian Xuesen always doubles his love and support. At that time, a young man from the Institute of Mechanics wrote to Qian Xuesen, pointing out that there was a mistake in Qian's physical and mechanical formula, and listing detailed demonstrations. After verification, Qian Xuesen found that he was indeed wrong. He wrote back to the young man and sincerely affirmed his argument. He invited the young man to write an article and recommend it to the Journal of Mechanics for publication. In the course of the vigorous development of China's aerospace industry, Qian Xuesen's moving story is actually a true portrayal of the scientific research predecessors of that generation. Is not the personality charm and immortal spirit reflected in it the fundamental driving force for China's space flight to leap from scratch, from weak to strong?
