Liu Daxiang (1937-)

Aviation dynamics, academician of the Chinese Academy of Engineering.

Liu Daxing's name is quite loud in the Chinese aviation industry. This is not only because he is the first academician of the Chinese aviation power industry, but also not only because he is the main technical person in charge of the first high -altitude simulation testing table in Asia, and has won the National Science and Technology Progress Award. In the front line of scientific research, hidden in the depths of Qingshan for thirty years, accompanied by the party and dedicated to the country, and the hard work of fighting for the hard work with the same way, making outstanding contributions to my country's aviation power industry.

Opportunity

Liu Dacheng was born on October 14, 1937 in Qinggong Temple Village, Township, Luokou -cho, Qitong County, Hunan Province. Qidong County was named after the east of Qishan in Qidong County. It was a place of Yangyue in ancient times. It was Chu during the spring and autumn. The painter's Guan Wei Fei and so on were bred here.

Although the Liu family had a good family, Liu Da was young when he was young. At that time, the lack of electricity, Liu Daxiang spent most of the late habits under the candle and steam lamp. It was not until his school of junior high school in Liu's private admiration in the county, and the school began to have electric lights.

This made the teenager Liu Dasheng deeply realize that without electricity, it could not develop. Therefore, Liu Daxing in middle school was very interested in electrical. He wanted to apply for the Department of Electrical Engineering of Tsinghua University, and was determined to engage in power generation in the future and contribute to the country's electrification.

Unexpectedly, an accidental opportunity changed Liu Daxing's life.

When he graduated from the third year of high school, the Beijing Academy of Aviation (now Beijing University of Aeronautics and Aerospace, hereinafter referred to as Beihang), as a national defense college, went directly to the grass -roots high school to select outstanding graduates.

After taking the complete national unified enrollment examination, after strict political trial, Liu Daxiang and five other students were guaranteed to enter Beihanghang.

In September 1955, when Liu Dacheng entered the gate of Beihang, he saw the wake -up target- "Welcome, the future red aviation engineer!" At that moment, it seemed that there was a heat flow to the whole body. Learn to be a good professional and serve the motherland.

Shortly after entering Beihang, Liu Dacheng was assigned to the aviation engine design, and since then he has been puzzled with the aviation engine. In his own words, "as a member of the Communist Youth League, there was no problem with what professional you wanted to choose at that time, and everything obeyed the organization arrangement." When filling in the form, he did not hesitate to write the words "obedience to allocation".

Liu Daxiang and aviation, especially aviation engines, can be described as "getting married first, then love". Over time, this love is becoming deeper and obsessed. For more than 60 years, no matter when and where, he did not leave the aircraft engine, and he had worked hard for this.

Do not enter the organ on the line

In 1960, Liu Daxiang was given a master's degree in a master's degree after graduating from the undergraduate.

In February 1962, due to physical reasons, Liu Dasing's application for closing in advance, losing a rare vice Dr. Graduate learning opportunity.

At that time, Beihang reported his archives to the National Defense Science and Technology Commission to determine the separate allocation.

One day in March, a comrade wearing a lieutenant school of the National Defense Science and Technology Commission interviewed Liu Dacheng, saying that after review, he agreed to accept him to work in the National Defense Science and Technology Commission. "Your office is on the fourth floor, you can see Beihai Park standing in front of the window."

After talking, the other party sought Liu Daxing's opinion. Liu Daxiang stated that he obeyed the distribution and arrangement of the organization, but still hoped to go to the front line of scientific research to do technical work.

After about 10 days, Liu Daxiang received a notice and arranged for him to work in the Sixth Research Institute of the Ministry of National Defense (now China Aviation Research Institute, hereinafter referred to as the Sixth Academy).

According to the requirements, Liu Dazheng reported to Tianjin Army Grain City, where the Sixth Academy was located. After staying there for 3 days there, the leader of a cadre department asked Liu Daxing to talk, saying that the Sixth Academy had just established a large number of scientific and technological management talents, hoping that he could stay in the hospital agency, and said go. Liu Dazheng stated that he still insisted on to the grassroots level and the front line of scientific research and production.

With the consent of the leadership, Liu Daxiang finally chose the second house in Shenyang. The second is a turbine jet engine. Liu Daxu's stamping engine is majored in the air jet engine.

During the college, he had been in an internship at the 410 factory. He knew that Shenyang was cold in winter, had more coarse grains, and had difficult conditions, but his majors were more opposite. In his opinion, only to Shenyang can learn better.

In March 1962, Liu Daxiang rushed to the second institution of Shenyang Sixth Academy (now China Airlines Shenyang Engine Institute, code 606) to report, and began a journey of struggle for his power.

There, Liu Daxiang met Wu Daguan, a well -known aviation engine expert and then the second technical deputy director of the technical technology. After that, the two also had more than 50 years of friends and made great contributions to my country's aviation engine industry.

In 1962, Liu Da rang in Shenyang.

Young man Liu Dacheng.

Say goodbye to the city and live in the ravine deep

624 is the second hometown of Liu Dacheng, which is located under the Wushan Wushan Mountain in Songhualing, the southwest of our country. From the age of 33 to 63, Liu Dazhen's most precious and beautiful years spent in this remote ravine.

In the thirty years of the fascinating ravine, Liu Daxiang used his own words and deeds to interpret the spirit of hard work and selfless dedication.

At that time, the New China quietly deployed the "heavy weapon of the country" -the aviation engine high -altitude simulation test desk (hereinafter referred to as a high -altitude platform), and opened the journey of dreaming of "China Heart" for Chinese aircraft.

In October 1970, in order to meet the needs of the development and preparation of my country's aviation industry, the Third Machinery Department established 11 House of Sixth Academy in Jiangyou, Sichuan (that is, the current 624 institutes, the current Chinese gas turbine research institute). Research Base.

With the approval of the Air Force Command, the superior decided to relocate all personnel of the seventh research room of the 606 to 624 people to 624 people to support the construction of the national junior third line.

At this time, Liu Daxiang was the father of three children. He went to the ravine of the mountains and mountains in northwest of Sichuan. The lover will face the distress of losing his professionalism.

Many people were hesitant, but Liu Daxiang still adhered to a sentence he often said, "Everything obeys the party's arrangement" and relocated his family.

When I first arrived in the Songhualing of the mountains and rivers, everyone was a little fresh, and they said and laughed. After a long time, the freshness disappeared, leaving only inexplicable loneliness.

In Liu Daxing's memory, because there are high mountains around, the sky here is darkened earlier than Shenyang. In the evening, people who are accustomed to living in the city are inevitably low: I feel like a lid with a hole in the sky, buckling myself in the mountains, in the middle Only a little bit of heaven, quite a sense of "frog at the bottom of the well".

However, Liu Dacheng couldn't tolerate himself, only fighting for the night, and he pierced into the work ...

At that time, the scientific and technological personnel transported electric poles when participating in 624 construction.

The high -altitude cabin arrived at 624 scenes.

In April 1974, Liu Daxiang was appointed Deputy Director of Room (High -altitude Taiwan Research Office), in charge of the debugging and engine testing of high -altitude platforms.

The high -altitude platform is designed by 624, so Room Eleven is a large room -the equipment design room of the entire high -altitude platform, but also the engine test room of the high -altitude platform and the ground platform, with as many as 128 people.

The team is built, how can it be technology? At that time, many people hadn't seen the "long" of the high -altitude platform and how to do it?

In early 1980, my country introduced the more advanced Spey MK202 turbofan engine production technology from the United Kingdom. After completing the ground test in China, it must be sent to the UK for the assessment test of high -altitude platforms. The assessment test is of great significance.

Before going to the United Kingdom to participate in the test test of the high -altitude platform of the Pesbei engine, Wu Daguan, the deputy head of the team, asked Liu Dacheng to talk to the leader of Liu Daxiang as the leader of the high -altitude platform assessment test team, and said, "This assessment test, your technicians of your 624 Institute of 624 It is necessary to do a good job of the Sibei engine assessment test, but also learn the test methods and experience from the United Kingdom. After returning to my country, we must build and debug our own high -altitude platform. "

During the assessment test of the high -altitude platform of the Sibei engine, the British only agreed to Liu Dacu to participate in the test, but did not provide any details and materials of the design, simulation technology, test methods and data processing technology of high -altitude platforms. Watch in the high -altitude cabin. As a result, Liu Daxiang organized all members of the assessment team to use all opportunities to see more and ask more during the day, ask British experts, come back to exchange discussions, take notes, and draw the main equipment.

After half a year of hard work, the assessment test was successful, and Liu Dazheng and his party also had a more comprehensive understanding and mastery of the equipment, systems, debugging and test methods of the British high -altitude platform. After returning from the British "scripture", Liu Daxiang organized everyone to write nearly 1 million words of overseas technical summary materials and reports.

In April 1980, the participants who participated in the high -altitude platform of the British engine (the second in the front row was Liu Daxiang and the third from the right was Wu Daguan).

"Do not make China's own‘ gas table ’,

Never leave the gap "

In September 1980, when Liu Dasing rushed their fists, they were going to use advanced technologies and experiences and experiences that the high -altitude description of the Spee engine learned in the UK for the construction of my country's high -altitude platform, but they encountered a great adjustment of the national economy in 1981. The second phase of the project is listed as a "slow construction project" -the funding reduction, the evacuation of the equipment installation team, the scientific research talents fly southeast, and the backbone of the skills is to do business. The original 128 people only left more than 60 people. Dark ...

Faced with the sudden "head", Liu Daxing, the director of the high -altitude platform test research office, bears tremendous ideological pressure and burden, confused, difficult to sleep, and thought hard.

He felt that he must first stabilize people's hearts. For this reason, he held a full -room mobilization conference many times, explaining the significance of the high -altitude platform over and over again. Be sure to stay to the end. "I have dedicated it to the high -altitude platform in my life, and I don't have the" Gas Table "in China. I will never leave the ditch and die in Songhualing and buried it in Guanwu Mountain." Seeing Liu Dacheng so firm, a group of backbones also have one after another. The expression of willingness to stay and continue to work, which gave him great support and encouragement.

The backbone talents are stable, how to get the next step? The huge and complicated high -altitude Taiwan can't wait for 5 years. If that's it, 5 years later, the high -altitude platform will become a pile of "waste copper and iron".

In order to find the method of cracking, the anxious Liu Dacheng began to go deep into the grass -roots survey and visited the backbone of the technical technical.

After the harmonious benefits, Liu Daxiang decided to take three measures: First, organize the "installation of the end of the assault team" -the borrowing several old technicians from the motorized office, plus the original workers and technicians, and then invited some local migrant workers to work hard. And he himself is both a cadre and a worker, working with everyone to work together to complete the installation and harvesting of equipment and systems; the second is to draft the proposal of "Restoration of the SB101 High -Aichi -Taiwan Key Project as soon as possible". This proposal has taken off the "stop and slow construction" hats later, and resumed a certain promotion role in the construction of key projects in 1984; the third is to actively apply for funding and conduct "high -altitude simulation test technology research" and "high -altitude platform one a one -one platform one. "Research on the Overall Performance Corporation of Period Engineering" laid a good technical foundation for the first phase of the high -altitude platform.

At that time, under extremely difficult conditions, all the staff of the high -altitude Taiwan carried forward the 624 spirit of "self -reliance, hard work, unity and cooperation, and selfless dedication", while installing, ending, debugging, and research, it was the same to "stop building". The three years have become a three -year research and debugging of the Heat, and the advanced technology they learned in the UK has been applied to the high -altitude platform in China.

In 1985, the SB101 high -altitude platform was successfully debugged by turbojet 7 engines, and the following year, the "Strange Stroscopy 13A II engine Import Stream Farm Farm Deficiency Simulation Exam" was completed the following year.

This not only contributes to the setting of the J -8I aircraft developed by my country, but also enables the first phase of the high -altitude Taiwan to be put into use 8 years in advance, and it has won valuable time for the construction of the second phase of the high -altitude platform. The confidence and determination of higher -level leaders and employees in the construction of high -altitude platforms.

Since the national approval of the national approval of the high -altitude platform construction project, through the unity and cooperation of nearly a hundred enterprises and institutions across the country, and the joint efforts of tens of thousands of builders, after the hardships of the 30 spring and autumn, the ideal pursuit and wisdom of the two generations have been condensed. A large number of outstanding people who have farewell to the big cities represented by Liu Daxiang, the farewell ravine, and selflessly dedicated to the country, finally passed the national acceptance in October 1995 and officially put into use. In 1996, the project was rated as "Top Ten Science and Technology Achievements in the Nineteenth Five -Year Plan", and in 1997, he won the National Science and Technology Progress Award and other prizes.

As an outstanding scientist trained in New China, Liu Dacheng achieved outstanding achievements and made important contributions to the country. In addition to the party's leadership and team, he was also inseparable from his personal solid scientific and technological ability and excellent ideological quality.

The colleagues who have worked with him for many years commented on him: the theoretical foundation is solid, closely linked to the actual situation; studying hard and studying, the logical thinking is clear;

In 2002, the Russian Academy of Sciences awarded a doctorate degree in honor of Liu Dacheng (academician of Favelsky, the Russian Academy of Sciences). The pictures are provided by the author

Lao Niu knows that the mission is heavy

After entering his old age, Liu Daxiang was very concerned about my country's aviation emergency rescue, and he was in danger.

As a common means of response to natural disasters and emergencies, aviation rescue has become the main rescue force of the emergency rescue system in many countries in the world today. At present, developed countries such as the United States, Canada, Russia, Japan, Germany, and Britain have set up a national aviation rescue center, forming a relatively complete aviation emergency rescue system.

my country's territory is vast, natural disasters are frequent, and emergency rescue has been uncomfortable with national conditions, socio -economic development, and the expectations of the people.

On May 12, 2008, a major earthquake occurred in the Wenchuan area of ​​Sichuan. Liu Daxing, who took Sichuan as the second hometown, was keenly discovered the problems exposed during the rescue process of aviation rescue: there were not enough ground equipment, there were too few navigation airports; Too complete, the aviation rescue system is not established; lack of professional, high -level aviation emergency rescue teams, etc.

On December 15th, at the ninth and seventh executive council held by the China Aviation Society, experts conducted a warm discussion on how to establish the "China Aviation Emergency Rescue System" after the Wenchuan earthquake in Sichuan, and believed that the establishment of national aviation emergency emergency emergency emergencyly The rescue system, enhancement of disaster resistance and emergency service levels are urgent.

On February 25, 2009, the Chinese Aviation Society organized a "high -level forum for aviation disaster rescue system construction". Liu Dacheng suggested that after the meeting, the drafting team wrote a research report based on this and submitted it to the central leader by the academician signature.

In early April of the same year, 27 academicians such as Gu Huan Fen, Shi Changxu, Zhuang Fenggan, Liu Daxiang, and Zhong Qunpeng were signed together to present the "Consultation Suggestions" to the central leaders.

The proposal first is to recommend the "General Plan for the Construction of the National Aviation Emergency Rescue System" and establish two special projects: "Aviation Emergency Rescue Equipment Development" and "Aviation Emergency Rescue Guarantee Conditions"; ", Organize the pilot work gradually.

It is very exciting that the Party Central Committee and the State Council attach great importance to the construction of the national aviation emergency rescue system. On the second day of the report, five central leaders comrades made important instructions to this.

On April 20, 2013, a magnitude 7.0 earthquake occurred in Lushan County, Sichuan. It is not enough to rely on the accumulation of experience in the place for a while, and it is not enough to rely on temporary and rescue forces in local areas. In the end, there is only one road to go, that is, to establish a complete national emergency rescue system, which is a major issue involving every people's vital interests.

On May 14, 2021, the Office of the State Council's Earthquake Relief Headquarters, Emergency Management Department, and the Sichuan Provincial People's Government jointly held the "Emergency Mission · 2021" earthquake relief exercise in Ya'an City, Sichuan Province.

In the meantime, Liu Daxiang said: Under the construction of a people -oriented harmonious society, the construction of an aviation emergency rescue system with "military -civilian integration and combination of disasters". When disaster occurs, aviation emergency rescue can reduce disaster losses. Through government funding, special insurance and society Donation and other measures allow the affected parties to enjoy "free" aviation assistance and experience "the party and the government are around me."

On October 13, 2021, in the interview with the collection engineering team, Liu Daxiang explained the issue of construction and development of the aviation emergency rescue system: "If the rescue system is established, the people benefit. After a catastrophic accident, as long as he calls for help, in half an hour, in the mountain area for up to one hour, our helicopter and medical staff will rush to the scene for treatment, and then use the plane to send him to the hospital ... "

Since 2008, Liu Daxiang has actively called for the establishment of a national aviation emergency rescue service system. It is recommended to open the low -altitude airspace, develop navigation industries, open non -traditional new aviation engine research, etc., and has successively received important instructions from the central leadership and strong support from ministries and commissions.

In March 2018, according to the reform plan of the State Council, the National Emergency Management Department was established to prevent resolving heavy security risks, improve the public safety system, and integrate and optimize emergency forces and resources. In December 2021, the State Council issued the "Fourteenth Five -Year Plan" National Emergency System Plan.

In recent years, Liu Daxiang, who entered the year of the puppet, still "fly" in the north and south of the motherland. As long as the conference, exhibition, and forums about the development of the aviation industry, he must squeeze out time to participate, and take the opportunity to vigorously promote the development of aviation emergency rescue and the development of the navigation industry. And the "heart disease" of the cure aircraft.

"Dedication of aerial power and determining the motherland to work hard." This is the belief that Liu Dacheng has been pursuing for more than 60 years.

Now he still shoulders responsibility and mission, running around and providing suggestions. "I am a cow. The old cow knows the mission and does not have to whip. In order to let the domestic aircraft install a strong‘ Chinese heart ’, I hope my life is endless and struggle.”
