Not long ago, President Xi wrote back to the members of the "Luo Yang Youth Commando" of Shen Fei, China Aviation Industry Group, encouraging them to study and implement the spirit of the 20 th Party Congress and make positive contributions to building an aviation power — —
"You take Comrade Luo Yang as an example, take root in the development of aviation equipment, and work hard together in urgent and dangerous tasks. This spirit of unity and struggle is very valuable."
Luo Yang, "Model of Aviation Industry". On November 25, 2012, at the age of 51, he fell on the triumphant way of the J -15 carrier aircraft successfully taking off and landing the carrier Liaoning ship. The heavy weapon of the country is cast by life. As the commander-in-chief of the domestic J -15 carrier-based aircraft development site, Luo Yang used his life to practice the clank oath of China aviation people to serve the country.
Today, it has been 10 years since Luo Yang, the "model of aviation industry", died.
Although Luo Yang has gone, the "air dream" is still flying. In June 2013, China Aviation Industry Shen Fei established the first batch of "Luo Yang Youth Commando", with an average age of only 30. In the past 10 years, Shen Fei "Luo Yang Youth Commando" has participated in more than 40,000 young people and solved more than 1,000 production technical problems.
President Xi’s reply not only inspired 12 members of the first batch of "Luo Yang Youth Commando" who wrote letters, but also inspired thousands of aviation youths and aviation people. Today, let’s walk close to four members of the first batch of "Luo Yang Youth Commando" and listen to their stories about the struggle of a new generation of airmen in the past 10 years.
Li Xiaodan, a first-class technical expert in aviation industry and senior engineer in charge of Shen Fei.
Faith carves youth.
Laser flashes in the air, materials are accumulated layer by layer according to the preset pattern, and metal parts with complex shapes are "carved" into shape.
Here, it is Shen Fei Technology Research Institute of China Aviation Industry Corporation. Li Xiaodan, a senior engineer in charge, is using the latest 3D printing equipment to produce parts for fighter planes.
Ten years ago, Li Xiaodan, who graduated from Northeastern University with a doctor’s degree, joined the aviation industry in Shen Fei. Here, she got to know Luo Yang, who is trying her best to solve the problem of carrier-based aircraft arresting hook.
"Mr. Luo took the technicians to scrutinize the details one by one and constantly adjusted the main direction and development mode. I only had a few contacts with him, but I can’t forget his tenacity. " Li Xiaodan recalled.
In 2013, with the increasing demand for high weight loss, long service life and low cost of new fighters, Shen Fei Company began to challenge the metal additive manufacturing technology which is extremely difficult to innovate. Take the initiative to fight, Li Xiaodan accepted this arduous task.
Additive manufacturing technology is known as 3D printing. Whether it is brand-new materials, unfamiliar technology or high-tech technology, it is a "blank" in the domestic aviation field. Li Xiaodan and his teammates must break through the technical bottleneck and get through the production line as soon as possible.
After accepting the task, Li Xiaodan led a 7-member team also from "Luo Yang Youth Commando", and at the same time carried out factory renovation and equipment debugging, working overtime until late at night every day. Sometimes, when Li Xiaodan walks out of the factory, he sees the morning light.
"At that time, we only had one belief, that is, to seize time." Li Xiaodan said. Finally, she and her team members completed the whole process trial production of typical process samples in only 28 days.
Winning the first battle doesn’t mean they have a breathing space. It is a long and arduous process from "producing" to "using".
In eight months, Li Xiaodan led the team to tackle key problems. In order to prove that the materials, processes and parts are qualified, they analyzed and verified all the performance data. In the end, the 800-page test report carried their painstaking efforts for 8 months, holding up the first additive manufacturing part and flying into the blue sky.
10 years, with a flick of a finger. From conception to application, from start to maturity, Li Xiaodan, as a witness, participant and leader, has experienced every step of the development of additive manufacturing technology — —
In 2016, a certain type of aircraft successfully made its first flight with dozens of additive manufacturing parts, marking that the technology has entered the stage of engineering application. At present, China has applied this technology to aircraft manufacturing on a large scale, and its technical level is in the leading position in the world.
"Faith is not a kind of learning, but a kind of behavior. It only makes sense when it is practiced. " After 10 years of searching, Li Xiaodan always remembered the spirit of Luo Yang. Only by daring to overcome difficulties can we move forward on the road of aviation technology innovation.
Sun Zhiqiang, a special skill expert in aviation industry and an assembler in Shen Fei.
Constant ingenuity and endless skill
Close your eyes and thread a wire with a diameter of 0.2 mm, which is equivalent to the thickness of three hairs, through the eye of a needle, which is almost the same. It only takes Sun Zhiqiang a few seconds.
As an assembler, Sun Zhiqiang has been practicing this skill every day for more than ten years.
Sun Zhiqiang’s main job is to complete the assembly, debugging and maintenance of fighter parts. The work in reality is far more complicated than "threading a needle with a wire". Fighter is a highly integrated precision system, and the operating space can only accommodate workers’ hands, and some circuit parts can’t even be seen directly.
In order to find an efficient operation method, Sun Zhiqiang began to exercise the flexibility and coordination of his hands intentionally, which is also called hand feeling. With this feeling, he is more familiar with the shape of the parts and more comfortable to operate, which greatly improves the assembly speed.
Sun Zhiqiang’s work notebook is full of various fault information. Colleagues joked that he knew the "temper" of the plane. He responded seriously: "There is no room for any mistakes in our work, and we can’t take it lightly at any time."
"Holding the state property in one hand and the life of a comrade-in-arms in the other." This slogan, which can be seen everywhere in the workshop, is also a motto deeply rooted in Sun Zhiqiang’s heart. As a member of "Luo Yang Youth Commando", he deeply felt the importance of his mission as an aviation man from his role model Luo Yang.
Damping part is a unique long rod part of carrier aircraft. Its installation, debugging and measurement are time-consuming and labor-intensive, which once became a difficulty in assembly work.
Sun Zhiqiang led the team through many field investigations and brainstorming, and finally developed two kinds of new equipment, which not only reduced the number of operators, but also improved the accuracy and work efficiency.
Looking through Sun Zhiqiang’s resume: after four years of employment, he obtained the qualification of electrician and assembler technician, and became the only compound talent who won the company’s "one specialty and many talents" for two consecutive years; After seven years’ employment, he obtained two senior technician qualifications; After 11 years on the job, he became a special skill expert in the aviation industry; After 12 years of employment, he won the National May 1st Labor Medal and was commended as a model worker in the aviation industry … …
Constant ingenuity, endless skills. From Sun Zhiqiang’s footprints, we can see the appearance of a great craftsman in the new era.
"Yes ‘ Hard bone ’ It is necessary to chew, and if there is difficulty, it is necessary to go. This is not only the charge of a Communist party member, but also the first batch of us ‘ Luo Yang Youth Commando ’ The team members are rooted in the heart. " Sun Zhiqiang said.
Liu Yanmei, special technical expert in aviation industry and chief metallurgist of Shen Fei.
Run faster towards your dreams.
Calm expression, gentle smile.
At first sight, it was difficult to associate Liu Yanmei with the word welding.
Now 42-year-old Liu Yanmei, the chief metallurgist of Shenyang Aircraft Corporation, shoulders the dual responsibilities of technology and management, and often runs around the office and various factories.
Dr Liu Yanmei graduated from Harbin Institute of Technology. Just arrived in Shen Fei, she volunteered to become a welder in the manufacturing engineering department.
In people’s usual thinking, there should be two straight lines between welding and female doctor. But Liu Yanmei has no time to pay attention to other people’s ideas. Starting from a welding technician, she has clearly written it into her career plan.
Liu Yanmei knew that in the future, aircraft components will tend to be large-scale and integrated, and aircraft production will start with parts. In order to connect the "skeleton", welding technology is indispensable.
"Only by keeping your feet on the ground can you look up at the stars." Liu Yanmei regrets.
Going deep into the welding production line with sparks flying, Liu Yanmei never complained about the hardships, but had more whimsy. In sincere consultation and discussion again and again, she turned the worker master in the workshop into her mentor.
The experience of "fighting" in the front line made Liu Yanmei combine theory with production practice more and more closely. She assisted professional leaders and carried out a number of research projects: realizing the popularization and application of a certain welding technology, solving the deformation problem of a certain welding part, and effectively improving the production quality of large-scale wall parts … … Gradually, people around you began to look at this "welding" female doctor with approval.
Only six years after joining the company, Liu Yanmei became the chief engineer of welding and additive technology in Shen Fei. Her responsibilities and pressures are constantly superimposed with the change of her identity. Make professional development plans, train professional talents, and ensure the smooth completion of production tasks … … She is leading an increasingly large team and speeding towards the future.
In the past 10 years, Liu Yanmei often felt that where the flag of "Luo Yang Youth Commando" fluttered, there was always a vigorous force that guided them to the distance.
In 2016, one day after work, Liu Yanmei, who had just served as the professional chief engineer, received the first-line news of production: a large component had abnormal detection. If the problem cannot be solved in time, it will affect the subsequent production process and even delay the time for troops to pick up.
Liu Yanmei immediately returned to his unit and set up a "Commando Team" on the spot to analyze the causes of the problems and work out solutions together with technicians, workers’ masters and inspectors. After continuous fighting day and night, they successfully ensured the qualified delivery of products. In Liu Yanmei’s view, perhaps it was the commando team flag that brought all people’s hearts together.
"Luo Yang once said that the common dream of aviation people is to make China’s aviation industry keep pace with the world in the competitive arena. This is all we have ‘ Youth Commando ’ The direction that the team members are working hard for. " In order to realize this dream, Liu Yanmei is still running at an accelerated pace.
Wang Gang, Chief Skill Expert of Aviation Industry and Milling Machine Worker of Shen Fei
A journey of a thousand miles begins with a nanometer.
"If you have any technical problems, just look for us." This resounding promise comes from Shen Fei’s first innovation studio — — Wanggang model worker innovation studio.
This is a studio led by workers.
Wang Gang Model Worker Innovation Studio was developed from "Wang Gangban", which brought together more than 80 skilled elites of different jobs in 10 factories of the company, and ensured everyone to continuously improve their innovation ability through membership system and elimination system.
It was Wang Gang, a 43-year-old "ace milling worker" of Shen Fei Group Company who created all this.
National Model Worker, Winner of Chinese Skill Award and Winner of National Patent … … This is a glorious label on Wang Gang. Regarding the accuracy of milling operation, the relevant national standards are between 0.008mm and 0.01 mm. With personal efforts, Wang Gang improved the accuracy to 0.005 mm..
"Believe in the power of innovation." This is the secret of Wang Gang’s success. In order to study the theoretical knowledge of milling workers, he bought a lot of relevant materials and plunged himself into the sea of books.
After studying, Wang Gang improved a series of traditional processing methods and greatly improved the production efficiency. Winning the honor, Wang Gang didn’t keep the technology for himself. He not only put all the materials he bought in the activity room for everyone to borrow, but also passed on the technology to everyone without reservation through lectures and exchanges.
"Wang Gangban" was established, becoming the first team named after employees in Shenyang Aircraft Corporation. Later, Wang Gang’s model worker innovation studio became Shen Fei’s first innovation studio.
Once, Wang Gang’s model worker innovation studio received an urgent task to process a set of high-end manufacturing technology product components. Wang Gang organized a discussion among studio members for the first time.
Modeling, programming and machining … … After receiving the task, the twin brothers Lan Tian and Lan Hai boldly improved the machining method, and greatly improved the machining accuracy and surface quality of the parts by relying on the unique technology of machining thin-walled parts.
Then, Li Xiaodan, an expert in additive manufacturing, finished the processing of the composite base, Sun Ming, a leading talent in CNC car specialty, made key auxiliary parts, and Fang Wenmo, a locksmith, carried out precision polishing & HELIP; … Under the traction of the studio, a number of professional jobs in Shen Fei cooperated with each other to overcome the original arduous level.
"President Xi mentioned in his reply ‘ Think in one place, and make efforts in one place ’ . I am particularly touched by this. " On the occasion of the 10th anniversary of Luo Yang’s sacrifice, Wang Gang was filled with emotion when he saw President Xi’s reply. —
"At a small scale, a team and a studio should focus on tackling key problems. At a large scale, Shen Fei and even the entire aviation industry should work together to forge ahead. Only ‘ Joint operations ’ In order to unite the strong synergy of aviation serving the country and aviation power. " (Liu Min)
