In 2002, after xiao Fei, 25, had just completed his undergraduate and master's studies from the Naval University of Engineering, he came to the university's national defense science and technology laboratory with a doctoral admission letter.
This was a very bold decision in Xiao Fei's life - to give up his promising doctoral status and turn to the laboratory as a "miscellaneous" experimenter.
It was also in this year that Xiao Fei broke the mindset in the laboratory, created a new calculation formula, and conquered the worldwide problem of power electronic excitation technology in one fell swoop, and then developed a converter that made China's ships far ahead of Europe and the United States.
Before that, Xiao Fei was just a lonely and nameless experimenter, who could imagine how powerful this young man really was?
Xiao Fei's childhood
Xiao Fei was born in 1977 into an ordinary family.
From a very young age, Xiao Fei liked some spaceship and battleship toys like other boys, but unlike others, Xiao Fei was more interested in how these toys were dismantled and then assembled.
Xiao Fei's father often bought toy cars for his son, but only half a day, when his parents did not pay attention, the car became a pile of parts in Xiao Fei's hands, but because he could not assemble it himself, Xiao Fei also received a lot of criticism from his parents.
When he grew up a little longer, Xiao Fei was also fascinated by the military channel.
He loved watching soldiers in military uniforms and camouflage uniforms on TV, as well as warships and tanks that could not be named.
It was also from that time that Xiao Fei hid a "military dream" in his heart, "When I grow up, I will also build airplanes, warships, and tanks." ”
Since elementary school, Xiao Fei's grades have always been among the best, although it is an "excellent child" in the eyes of others, But Xiao Fei's parents have always had a headache about Xiao Fei's hobby of tearing down toys.
When he was in junior high school, Xiao Fei read China's first artificial satellite "Dongfanghong I" and read Comrade Qian Xuesen, a strong sense of pride sprang up, and at the same time he was deeply attracted by the knowledge in it.
Xiao Fei couldn't help but think all day long, "How did this satellite fly into the sky?" How is the internal structure structure constructed? What fuel should I use to take off? Will the satellites return to the ground later? ”
A series of questions kept beating out in Xiao Fei's mind, and these questions also strengthened his idea of engaging in military research in the future.
After graduating from high school, Xiao Fei was admitted to Wuhan Naval University of Engineering with excellent academic performance.
Here, Xiao Fei finally realized his military dream for many years, and also began with this university and embarked on a career in military research.
However, Xiao Fei's footsteps and dreams are far more than that.
In Xiao Fei's view, "Only by constantly arming your mind with knowledge can you go further on the road after that, from a person who absorbs knowledge to a person who creates knowledge." ”
In 2002, Xiao Fei completed his undergraduate and master's studies from the Naval University of Engineering, and then was admitted to the university as a doctoral student.
It was originally a bright road that looked smooth and smooth, but the appearance of Academician Ma Weiming at this time directly changed Xiao Fei's next life trajectory.
One give up, one chance
Academician Ma Weiming was a professor at the Naval University of Engineering, and at that time a technical group of the Key Studio of Ship Integrated Power Technology and National Defense Science and Technology led by him was carrying out an important experimental task, but the talent in this area of the laboratory has always been in short supply.
At this time, Academician Ma Weiming needs to recruit an experimenter who assists the laboratory in recording basic data and sorting out data on a daily basis.
In general, this experimenter is in the laboratory to the predecessors as an assistant to do chores, doing some insignificant and tedious work.
For many people, giving up their hard-earned doctoral students to become a lonely experimenter is really overkill and wastes their time and energy.
But Xiao Fei didn't think so in his heart.
You know, this is the laboratory led by Academician Ma Weiming.
At the age of 42, Academician Ma Weiming was promoted to rear admiral and was awarded the "August 1st Medal" on July 28, 2017, and the laboratory where he worked was also a key laboratory in the mainland's national defense science and technology.
In addition to understanding the laboratory background of Academician Ma Weiming and his own excellent professional skills, Xiao Fei made a bold decision in his heart, and he was determined to give up the opportunity to study for a doctorate and become a researcher in Academician Ma Weiming's laboratory.
This seems to many people to be an incredible thing, but Xiao Fei believes that this is an extremely rare scientific research opportunity for him.
It is better to read thousands of books than to travel thousands of miles.
No matter how much knowledge you read in the book, it is better to benefit yourself more in practice.
Academician Ma Weiming's laboratory is overcoming technical difficulties, and after completion, it will upgrade the mainland's naval power system to a new stage.
So that year, Xiao Fei took the admission letter of his doctoral student and took the initiative to find Academician Ma Weiming and explained his intentions.
Soon after, Xiao Fei submitted an application to the laboratory to serve as an experimenter.
This is the first project in Xiao Fei's scientific research career, and it is from here that Xiao Fei is one step closer to his dream.
Due to the high starting point of Academician Ma Weiming in this laboratory, the projects in hand have a certain degree of difficulty.
As a newcomer in the laboratory, Xiao Fei wants to systematically manage the laboratory, and he must be required to have a certain degree of familiarity with these project materials.
In the position of an experimenter, these trivial things are the most basic work in Xiao Fei's hands every day.
In order to obtain the latest data in the laboratory, Xiao Fei worked overtime in the laboratory until two or three o'clock in the morning.
Everyone could see that this new little friend was really desperate, and when the task was tense, Xiao Fei even regarded the laboratory as his home.
However, it is precisely in the long-term process of this trivial and meticulous work that Xiao Fei not only has a comprehensive understanding of the equipment of the laboratory, but also consolidates the basic theory of the system and accumulates a lot of practical knowledge in engineering.
It is the accumulation of this period of time bit by bit, two years later, Xiao Fei not only completed the mission of the laboratory as desired, but also was admitted to Zhejiang University as a doctoral student.
In the laboratory, the vast majority of scientific research topics in which Xiao Fei participates are key technologies that are basic and cutting-edge in the design of national defense.
With this indomitable spirit and tenacity, Xiao Fei immersed himself in research, worked hard to tackle key problems, and successively presided over and participated in more than ten major scientific research projects such as the National Natural Science Foundation of China, the National 973, and the development of major national defense equipment, many of which have now reached the same advanced level in developed countries, enabling the mainland to achieve a qualitative leap in many emerging fields.
At the age of 25, he created his own formula to solve the world's problems
It is said that after Xiao Fei came to the National Key Laboratory of Science and Technology of Ship Integrated Electric Power Technology, the first scientific research project he focused on was a worldwide problem about the "new high-speed induction generator system".
At that time, in the process of researching this project in the laboratory, no substantial progress was made, and the entire laboratory encountered unprecedented problems, and the scientific research progress was very slow.
Xiao Fei, who observed meticulously, quickly discovered the key problem, and during the project's research, the voltage output of the generator used in the experimental process was often unstable, and this difference had a crucial impact on the final data of the experiment.
As the saying goes, if you lose a millimeter, you will fall for a thousand miles.
In the experimental research, at that time, not the slightest mistake was allowed.
So Xiao Fei decided to first overcome the problem of the output voltage of this generator, and if he wanted to succeed in the experiment, he must start from here.
After continuous research, Xiao Fei pioneered that this problem can be solved by using power electronic excitation technology.
However, the application of this technology in China is almost blank, and there is no information on the key technology in China that can be queried.
For this technology, there is no ready-made solution, which not only requires an extremely complex mathematical formula to calculate the relevant technical parameters, but also needs to ensure that this formula and whether this technology can really be applied to the power generation system.
Xiao Fei later found a formula that had been deduced and completed in a foreign academic journal, and Xiao Fei was overjoyed at this time.
However, when Xiao Fei used this formula to carry out experimental calculations, the final data frequently had various problems, and the two results calculated were also mutually restrictive.
In desperation, Xiao Fei had to check and review his experimental data over and over again, and then do some targeted experiments according to the loopholes in the data.
Xiao Fei no longer knew how many times he had failed, but the final data results were still unsatisfactory.
During that time, Xiao Fei couldn't sleep every night.
When I fall asleep, I always ponder what went wrong with my experiment, practicing step by step, and deducing step by step.
His own experimental data is not wrong, but the experimental progress cannot be broken, which has always made Xiao Fei helpless.
Obviously, it is step by step according to the steps of the publicity, why can't you get the results you want?
At this time, Xiao Fei suddenly had a flash of inspiration and had a bold idea.
My experimental steps are correct, the data is also correct, then will the formula of this experiment be wrong?
Thinking of this, Xiao Fei suddenly opened up.
Who says that foreign formulas are necessarily correct?
Who says this formula can't be changed?
As a scientific researcher, job hunting and exploration is the natural duty, scientific researchers should hold the attitude of doubting everything, and then step by step to practice the truth.
Xiao Fei decided not to use the previous calculation formula, but to re-deduce and create one himself.
Looking at the experimental manuscript on the table, Xiao Fei's heart was extremely excited.
After re-examining his experimental data and loopholes, Xiao Fei proposed a new formula and algorithm, which allowed Xiao Fei to overcome a worldwide problem in one fell swoop, and also made a major breakthrough in the field of power electronic excitation technology.
Xiao Fei was only 25 years old that year.
Converter technology has made continental ships ahead of Europe and the United States
At that time, the development of Chinese naval vessels, like power electronic excitation technology, relied on foreign technology.
Because many of the necessary instruments and related equipment are almost monopolized by some large companies in Europe and the United States, not only the price is high, but even the conditions for import are very strict.
Under such conditions, the progress of China's naval ship industry is slow.
Xiao Fei was full of enthusiasm and determined to develop new technologies to change this passive situation of the mainland navy.
Academician Ma Weiming believes that China's naval ships are now relying on foreign wind power generation technology, so we can now rely on the mature base of the domestic electrical field to overcome this difficulty.
That is to say, if the converter system currently used in the ship's high-speed generator can be changed, it will change the current passive situation of the continental navy, and this technology can be applied to the wind power industry or other applications such as aircraft.
The project was led by Xiao Fei and several young people to form a research group.
After nearly two years of difficult research, Xiao Fei and his team members finally successfully designed a 2 MW permanent magnet direct drive wind power converter.
In order to verify the application of the converter in real life, Xiao Fei and the team members went to many places in China to experiment with the performance of the data.
For Xiao Fei, technological innovation is only a small step in scientific research results.
Only by applying technological innovation to engineering practice can we be truly successful.
In order to make the scientific research results bear the fruits of victory, Xiao Fei also led the scientific research team to extend his workplace all the way from the laboratory to the depths of the mountains, and finally to the factory and workshop stationed in a certain place.
In order to meet the technical specifications and test requirements, Xiao Fei seems to be transformed into an all-round "superman".
At this moment, Xiao Fei was not only the director and professor of the research institute, but also a technician in the factory for a while.
During that time in the factory, Xiao Fei spent a lot of time every day in the factory with the technicians to discuss the structural optimization and integration problems under the high power density requirements of the converter.
Xiao Fei also laughed and said, "When it comes to these application problems in real life, we should still ask these workers and masters, they are the front-line workers of production, and only by discussing and researching with them can we know whether there is any problem with our experimental results." It sounds like people call me professor, but in fact, I am just a gray-headed technician in the workshop. ”
Under such conditions, Xiao Fei analyzed the various difficulties and reasons encountered in the production and manufacturing process with the master workers, and at the same time personally started to do the production process and process of the factory.
Xiao Fei often said, "What we do in scientific research is to race against time, to race against opponents, and most importantly, to race against ourselves." In the process of experimentation, it is a process of repeated failure, followed by repeated revision and repeated argumentation. Without this patience and tenacity, even if there is good luck from Heaven, it will not be your turn. ”
After continuous innovation and experimentation, the project on the 2-megawatt permanent magnet direct drive wind power converter studied by Xiao Fei's group was finally successfully developed, breaking the long-term monopoly of the field by foreign countries in one fell swoop.
A project saved 1 billion yuan and won the first class of national merit
Until now, the 2 MW permanent magnet direct drive wind power converter independently developed and produced by the mainland has passed the appraisal in Wuhan, Hubei Province.
After the relevant experiments of the wind power plant, it was concluded that the relevant indicators and performance of the converter were better than similar products abroad.
That is to say, the scientific research results developed by Xiao Fei's group have been completed to replace imported products, and this converter has a large power density, high operating performance, and due to harsh ecological conditions, the converter can still adapt safely.
In addition, the converter can be directly matched with the corresponding wind turbine and provides a high-quality power supply that meets the standards.
This scientific research achievement can not only meet the needs of the mainland's future wind power applications, but also expand to other application fields such as ships and aircraft, because it breaks through the foreign technology blockade, and the strength of the Chinese Navy's ships in the application of this technology is also directly ahead of European and American countries and reaches the world's advanced level.
After Xiao Fei's scientific research achievements were widely used, foreign products of the same type appeared a cliff-like downward trend, which saved about 1 billion yuan of procurement funds for the country that year.
Because of this scientific research achievement, the young Xiao Fei was also highly recognized by the Headquarters of the Chinese People's Liberation Army.
Previously, Xiao Fei also won first-class merit.
In this era of peace, there are not many people who can obtain the honor of "first class merit" in such a peaceful way.
Xiao Fei relied on his excellent strength to let the country get rid of its dependence on imported technology, and he really deserved the honor of "first-class merit".
On November 18, 2019, Xiao Fei won the 2019 He Liang He Li Award.
The original intention of the establishment of the Ho Leung Ho Lee Fund is to reward scientific and technological talents like Xiao Fei who have made outstanding achievements and have major innovations, and Academician Zhang Jinqiu has previously won this award.
Today, Xiao Fei has long been upgraded from an experimenter to the director of a research institute of the Naval University of Engineering and a professor of the National Defense Key Laboratory of Integrated Power Technology of the School of Electrical Engineering.
Professor Xiao Fei, who is conscientious in his career, is also a father in real life.
But because of his busy work, Xiao Fei has very little time to really accompany his wife and children.
On the one hand, it is the responsibility of guarding the family as a husband.
On the one hand, he is guarding the country, which is his responsibility as a Chinese.
In Xiao Fei's heart, full of selflessness and dedication, under the protection of such generations, China has become stronger.
