Last year, General Secretary Xi Jinping replied to the employees of the "Li Zhiqiang Class" of AECC Liming Engine Assembly Plant, putting forward ardent expectations for the development of aero engines. This year's government work report once again mentioned that "great progress has been made in the development of high-end equipment such as aero engines and gas turbines".
The party and the state attach great importance to the aero engine industry and fully affirm it, which makes Li Jianrong, assistant general manager of China Aero Engine Group and deputy director of the Science and Technology Committee, very encouraged, and at the same time deeply feel a great responsibility. "The aero-engine business has ushered in an unprecedented spring. We must rely on innovation and firmly grasp the key core technologies in our own hands. She said.
Immerse yourself in the development of the model
As a rare female general in the field of aero engines in Continental, Li Jianrong has been at the forefront of aero engine research for nearly 40 years. Winner of the National Science and Technology Progress Special Award, National Defense Science and Technology Progress Special Award, and National 38 Red Flag Bearer...... The honors have witnessed Li Jianrong's responsibility and responsibility, as well as the road of independent research and development and innovation of aero engines.
When asked why he chose this industry, Li Jianrong said with a smile: "At that time, I just thought that the work that can make behemoths fly must be very good!" ”
With a simple yearning for aero engines, Li Jianrong was admitted to Nanjing University of Aeronautics and Astronautics in 1983 and chose to major in aero engines, starting a career journey of more than 40 years. "At that time, many of the masters were college students who graduated in the fifties and sixties of the 20th century, and in the face of technical problems in the development and the development process affected by various factors, they were always indomitable, and strengthened their confidence and determination to develop engines independently, and they paid their youth and sincerity, and this atmosphere, spirit and determination infected me." Li Jianrong said.
Witnessing the Taihang engine from a drawing to the real thing, from static to operation, from test flight to service, Li Jianrong said that this is a kind of luck. "At that time, everyone united, regardless of gains and losses, devoted themselves to the development of the model, the test process night and day troubleshooting, the persistence of extreme high temperature, high cold, and high noise in the field, the holding of breath when monitoring the parameters, the accumulation of technical decisions, all the hardships and the joy of overcoming difficulties and the joy of model development results, everything is worth it. I am very fortunate to be able to participate in this national project at the beginning of my work and to participate in the entire development process of the project. Li Jianrong said.
Since then, Li Jianrong has been responsible for, supervised and participated in the research of many new projects and technologies. The nature of the work has evolved from model development to pre-research to basic research, and the initial dream and love have gradually been integrated into the specific work and into the belief in the realization of independent research and development of aero engines.
In August 2016, the CPC Central Committee and the State Council set up the China Aero Engine Group from the strategic height of enriching the country and strengthening the army, serving to accelerate the pace of independent research and development of aero engines. Li Jianrong served as the first chief researcher of the Institute, mainly responsible for strategic, cutting-edge and basic research tasks of aero engines.
After its establishment, AECC has anchored the development goal of "becoming a leader in aero engine strategic research, an explorer of independent innovation and development, and a leader in the construction of R&D system", deeply implemented the "innovation-driven" development strategy, boldly innovated, forged ahead, continued to nurture and promote breakthroughs in aero engine technology research and the cultivation of innovative talents, and strived to become a source of living water for the original innovation and cutting-edge scientific research achievements of aero engines. In March 2020, he became the president of China Aviation Development Research Institute, and the burden on Li Jianrong's shoulders is heavier.
Always put scientific and technological innovation in the first place
Aero engine is one of the most complex and sophisticated disciplines in human history, with a long development cycle and large investment. In Li Jianrong's view, the aero engine is known as the "crown jewel" of modern industry, and is an important embodiment of a country's science and technology, industry and national defense strength.
"On the one hand, aero engines are technologies that are close to the limits of classical mechanics in engineering applications, and it is extremely difficult to innovate. We should not only focus on technological development and break through bottlenecks and difficulties as soon as possible, but also explore and innovate, break traditional thinking, create innovative power such as new configurations, new concepts and new energy, give full play to the advantages of the new national system to create an innovation platform, and jointly promote the continuous development of new quality productivity. Li Jianrong said.
Since its establishment, AECC has taken innovation-driven as the first of its three major strategies. In recent years, AECC has aimed at the "hard bones" that restrict the development of aero engines to reform and innovate the system, innovate the R&D model, optimize the echelon of professional talents, build a digital collaborative research and development platform, strengthen the research and application of simulation technology, and realize the one-step design of multiple models, the trial production is done right at one time, the test is successful at one time, and the performance is up to standard, and innovation has become a powerful booster for the independent development of aero engines to increase afterburner.
Forty years of perseverance, Li Jianrong has witnessed China's aero engine industry from maintenance, testing and imitation to independent research and development, independent development of several stages, she sighed: "The key core technology is not to come, can not be bought, can not be bought, only by relying on innovation, accelerate the key core technology in their own hands, in order to fundamentally ensure the national economic security and national defense security." ”
Under the influence of Li Jianrong, more and more female researchers have gradually taken up the burden of her training and demonstrated their talents in some important scientific research projects. "Women researchers have played an important role in the development and innovation of aero-engine technology. We have female doctors, female chief teachers, female deans and female academicians, and the meticulousness and tenacity of women reflect their unique value in innovation. Li Jianrong hopes that young scientific research workers can work hard to climb in scientific and technological research positions, sharpen and grow into women in the new era who have ideals, dare to take responsibility, can endure hardships and are willing to struggle, demonstrate their motivation and creativity in the acceleration of scientific and technological research and development, and display their ambitions and achievements on the broad stage.
"Today, we have the ability of independent innovation and development, and will continue to unswervingly focus on national needs, innovation and development, carry out independent innovation research on new energy and new power, simulation technology and other projects, and strive to achieve and complete the mission and task of aero engine development." When it comes to the future, Li Jianrong is full of confidence.
It's a long journey
There is only struggle
Salute to every struggler!
