Yang Liwei: Han nationality, born in June 1965, flew into space with the Shenzhou 5 spacecraft at 9: 00 on October 2003, and landed safely at 6: 23 on June 16, becoming the first person in China.
Xie Guangxuan (1922-)
He used to be the director and vice president of the overall design department of China Academy of Launch Vehicle Technology.
Expert in missile and launch vehicle technology. Engaged in weapons technology in his early years. We have successfully developed the first generation of rocket timers and anti-tank rockets in China, which were called "Xie Guangxuan Bomb" in the 1950s.
After being transferred to the Fifth Hospital of the Ministry of National Defense, 65438-0957 participated in the development and technical leadership of various weapons and launch vehicles.
Chief designer of medium and short range rocket, chief designer of cz-3, chief engineer of Aerospace Department, and consultant of Science and Technology Committee of Aerospace Department. Successfully organized a thermal nuclear test combining missiles with atomic bombs, which played an important role in the application of key technologies such as cryogenic technology. He has won two special prizes of National Science and Technology Progress Award, National Defense Science and Technology Achievement Award 1 special prize, Heliang Heli Fund Science and Technology Progress Award, and won the first class in aerospace 1 time.
1987 was elected as an academician of the international academy of astronautics.
199 1 was elected as an academician of China Academy of Sciences.
1962 In March, when the flight test of DF-2, the first small short-range first-class rocket designed by China, failed, He, as the overall chief designer, effectively completed the relevant work. Firstly, the elastic theory is used to describe the lateral natural elastic vibration of the rocket, and the failure reason is found by analyzing the flight stability equation, thus perfecting the flight theory. Secondly, combined with the development practice, according to the idea of "strengthening the ground test, anything that can pass the ground test or simulation test should not be assessed in the flight test", summing up foreign experience, and according to the requirements of system engineering, the 17 ground test development scheme is compiled, which can only enter the flight test through single and comprehensive tests, effectively guiding the subsequent model development and making important contributions to the success of rocket launch.
1966 In the first half of the year, with the approval of Premier Zhou Enlai, Xie Guangxuan was appointed as the head of the technical coordination group for missile nuclear weapons testing. After in-depth investigation and verification, he took a series of technical safety and reliability measures at the fastest speed, ensuring the success of the1966 65438+1October 26th "two-bomb combination" test with the best quality and reliability.
1974,1/kloc-0 In June, 2008, the first flight experiment of the Long March II secondary rocket failed because of a broken wire. He was assigned to organize the second launch and took five technical improvement measures to correct and remedy the design defects. For example, redundancy technology has improved the reliability of rocket design, and according to the harsh environment of the Cultural Revolution and the current situation of poor product quality, the testing and inspection work has been further strengthened, and dozens of instruments and equipment on the rocket have been replaced in time. Through painstaking and meticulous work, the successful launch of1975165438+1October 26th was ensured. The carrying capacity of China launch vehicle in near-earth orbit reached 1.8 tons, and its reliability was improved, which made China successfully launch a recoverable satellite for the first time.
During his tenure as the overall designer of the Long March III D three-stage rocket, he played a good role in organization, guidance and decision-making, solved a series of key technical problems, and made great contributions to the successful launch of China's first geosynchronous orbit satellite. For example, the longitudinal coupling vibration of the whole missile is effectively suppressed, the amplitude of low-frequency vibration is reduced, and the low-frequency vibration environment is improved, which lays a certain foundation for manned flight design; The organization has overcome the key to the application of cryogenic technology, paved the way for the adoption of liquid hydrogen/liquid oxygen propellant technology, and established dozens of research topics, making China the third country in the world to adopt cryogenic propellant. The first launch of Long March III 1984 1. Although it was only a partial success, it achieved important results. After in-depth analysis, the hazards of low gravity field two-phase flow and high vacuum three-phase flow (gas, liquid and circulation) were clarified, the failure modes were summarized, and three measures were taken to solve the key technologies such as the second start of the engine under the condition of high altitude weightlessness, which made the launch vehicle technology in China reach a new level, thus ensuring the successful re-launch on April 8 after 1984 70 days. In his congratulatory message, the head of NASA believes that only a few countries in the world can achieve the technical capabilities shown in this launch.
