She is the only female chief designer and the youngest chief designer of China Long March Rocket. She led the team to constantly refresh the safety index record of manned rockets. Her name is Yi, but she chose a very difficult career, from manned rocket to heavy rocket research and development. Yi, with the responsibility, perseverance and hard work of a * * * party member, has created new breakthroughs in China's space flight again and again.
Only when you know what you know can you stay calm, which is an experience that can be easily gained after numerous tempering at work. In 2006, Dr. Yi became a rocket designer after graduation. In 2009, she undertook the design of Chang 'er F rocket escape system, which is directly related to the life safety of astronauts.
In 20 12, the shenzhou-9 spacecraft was launched, and it was easy to see astronauts board their own rockets for the first time. In order to improve the safety and reliability of rockets, it is easy to master the core technology of rocket safety design in the shortest time. She also innovatively put forward a variety of fault judgment basis and treatment methods in the process of rocket flight, which made the safety of manned rockets break through continuously.
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 easy to lead the research team to carry out detailed research on the design margin of differentiated carrying capacity based on configuration, which provides an 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.
Explore smart rocket technology, adopt mission target classification mode, and improve the mission adaptability of heavy launch vehicles from the design source. A series of significant progress has been made, such as the structural design and manufacture of large-scale arrow bodies.
