Yi, female, Tujia, China * * * production party party member. I graduated from National University of Defense Technology, majoring in aerospace engineering in the former Department of Aerospace Technology 1997. I graduated from Tsinghua University in 2006 with a doctor's degree in engineering. I was born in Jianshi County, Enshi Tujia and Miao Autonomous Prefecture, Hubei Province in March 2008. He is currently the chief designer of the First Research Institute of China Aerospace Science and Technology Corporation, a member of the 14th CPPCC and a member of the Standing Committee of the All-China Women's Federation.
Upon graduation, he was easily assigned to China Academy of Launch Vehicle Technology, which is the oldest and largest research, test and production base of missile weapons and launch vehicles in China. From then on, it is easy to become the advantage of the rocket. In the eyes of many people, the research and development of missile rockets are basically dominated by men, and few women are rooted in this big country. However, it is easy to play a stable role in the rocket field and work harder than others to reach the competence standard.
Major achievements
During my work, I won the second prize 1 item for scientific and technological progress of a system, granted 6 patents, accepted 6 patents, and published more than 30 scientific papers in academic journals and conferences at home and abroad. Yi is now the academic and technical leader of the group company and the chief expert of the overall transportation technology of the First Hospital. Enjoy the special government allowance of the State Council, win the China Association for Science and Technology Award for outstanding young people seeking truth from facts, and win the honorary titles of "Capital Spiritual Civilization Construction Award", "Central Enterprise Model Worker" and "National March 8th Red Flag Bearer".
As the deputy chief engineer of heavy-duty launch vehicle, Yi led the scientific research team to tackle key technologies of China's next-generation launch vehicle. The scale and capability of heavy launch vehicles are basically several times that of Long March 5, so it is impossible to give an optimized design scheme by traditional means and applying traditional knowledge.
Therefore, it is convenient to lead the research team to carry out detailed research on the design margin of differentiated carrying capacity based on configuration, and provide important reference for the scientific reservation of carrying capacity; The joint optimization design of overall trajectory, power, load and structure is carried out, and the best time and range of thrust adjustment are given in detail. Through trajectory optimization, the traditional axial load is greatly reduced from the design source, thus optimizing the structural weight of the arrow body and laying a solid foundation for ensuring the carrying capacity and efficiency.
