The beautiful white chrysanthemum basket brought cordial greetings from Chairman Li Peng. "What is providence? ! "Luan Enjie, deputy director of the Commission of Science, Technology and Industry for National Defense, could not express his regret. On February 5, 2002, the first farewell room of Babaoshan cemetery in Beijing was heartbroken and in tears. More than 20 new and old ministers and 10 generals led a team to attend the farewell ceremony of Professor Yang Weimin from Beihang University.
Like a meteor burning with life, Professor Yang Weimin, the founder and pioneer of the national reliability engineering specialty, the director of the Reliability Engineering Technology Center of the General Armament Department and the Commission of Science, Technology and Industry for National Defense, and the 67-year-old director of the Engineering Systems Engineering Department of Beihang University, left his infinite attachment to the reliability cause of China, strong personality charm and spiritual wealth.
People familiar with Yang Weimin said, "He is exhausted." He doesn't want to spend time to see a doctor, and he is stingy with his rest time. Colleagues say that he is like a tireless "perpetual motion machine". On one occasion, colleagues found him working overtime and staying up late in the office for 8 consecutive nights. Coffee, cigarettes and strong tea refreshed him, and when he was tired, he slept on the sofa in the office.
Yang Chongyi, Yang Weimin's assistant, said emotionally, "Yang Weimin's itinerary is marked in several colors, and sometimes he flies to several places in China every week. We even waited for his connecting flight at the airport with air tickets. He has too many things, too important to stop. "
In June, 20001year, Yang Weimin, who was too weak to support, was diagnosed with pancreatic cancer. During the inspection, Yang Weimin went to work during the day and saw a doctor at night. One night, in order to prepare a summary report on the inspection and exchange of key projects of the General Armament Department, Yang Weimin called Professor Tu Qingci to the hospital and dictated the report while hanging a drip. The two of them studied writing until nearly 1 1 point. A few days after waiting for the final diagnosis, Yang Weimin went to Miyun to chair a meeting. At that time, he could not eat anything.
On July 1 day, 2006, Union Medical College Hospital operated on Yang Weimin. Because of the advanced cancer, it is impossible to remove the tumor and only palliative treatment can be carried out. Yang Weimin knew that his time was running out. He always calls people to the hospital for meetings, turns the ward into an office, and often writes notes to ask for leave to go out for meetings and work. However, the analgesic plaster on his chest increased from 0.25 units in the hospital to 2 units, which became eight times the original.
The head nurse sincerely lamented: "Everyone who is terminally ill is enjoying every day of his life, while Teacher Yang regards every day of his life as his enjoyment."
Resolutely turn to childlike innocence
In 1970s, Yang Weimin, as the chief designer and commander-in-chief of the high-altitude unmanned photographic reconnaissance plane, led thousands of teachers and students to struggle for nearly 10 years. This aircraft filled the gap in China, won the second prize of National Science and Technology Progress Award, and was equipped with the first UAV unit in China. This achievement has been engraved on the bronze aisle of the China Millennium Monument, which has become a portrayal of the endless glorious history of the Chinese nation. In the flight test, Yang Weimin had more than 40 stitches on his face, but he stayed at the scene for more than 40 days. Results The wound was purulent and infected, and the low-grade fever continued, leaving a permanent scar.
In 1980s, Yang Weimin found through extensive investigation that at that time, due to the lack of reliability guarantee, China's military aircraft had a high failure rate, about half of which were "prone to collapse" and had a short service life, which seriously affected the combat effectiveness of the army. He is keenly aware that not only airplanes, but also land, sea and air urgently need to open up virgin land for the application of reliability engineering.
Yang Weimin said: "The needs of the country are our choices." At the age of 45, he resolutely led the UAV development team into the new frontier discipline of reliability engineering, stepped out of the ivory tower, and determined the research route of "engineering-oriented, combining with reality". He constantly reminds everyone that our task is not only theoretical research, but also solving practical engineering problems.
Yang Weimin established a unique engineering system engineering department in Beihang University. Under his leadership, the department has grown from more than 50 teachers and more than 30 undergraduates to hundreds of teaching and research personnel, hundreds of undergraduates, 67 master students and doctoral students, and built the largest reliability engineering research team in China. Up to now, it is still the only base in China that systematically trains reliability engineering talents.
Double reliable public comment
Through 20 years' continuous development and innovation, Professor Yang Weimin pushed the reliability engineering in China from bud to blossom.
Yun Qi is a passenger plane developed by China. Due to the lack of reliability engineering research, manufacturers stipulate that the life of their airborne equipment is only 300 to 500 flight hours. Therefore, the civil aviation department is unwilling to use the "seventh operation" and prefers to spend precious foreign exchange to import foreign aircraft. In the early 1980s, Yang Weimin organized researchers to conduct long-term life tests. After nearly five years' efforts, the first overhaul period of airborne equipment of Yun Qi aircraft has finally been extended to 2,500 to 5,000 flight hours, reaching the level of similar aircraft abroad. The success in fixing and extending the service life of Yun Qi aircraft has improved the position of domestic aircraft in people's minds and made it the largest domestic fleet in China airport. According to statistics, the life extension of airborne equipment alone saved the country more than 200 million yuan during the Seventh Five-Year Plan period!
In the mid-1980s, the reliability engineering application of China's weapons and equipment was still blank. Without the reliability index of the equipment, users could not put forward reliability requirements for the contractor, let alone check and assess. Yang Weimin came forward to pay for the first time to bring together users, contractors and colleagues engaged in reliability engineering research, and held a seminar in Qingdao to introduce foreign research and application, and we discussed the reliability standards of our military weapons and equipment together.
Through continuous efforts, the General Armament Department and the Commission of Science, Technology and Industry for National Defense have successively issued red-headed documents, stipulating that new equipment should have reliability parameters and indicators. Since then, the reliability work has been guaranteed by the system, and from the beginning of design, reliability has been running through. It can be said that Yang Weimin has made great contributions to the formulation of national military standards for reliability parameters and indicators of weapons and equipment in China.
The theory and method of reliability system engineering put forward by Yang Weimin have also been widely used in national defense science, technology and industry. Planes, missiles, rockets, spaceships, satellites, nuclear submarines, tanks ... all these "creatures" carefully cultivated by Yang Weimin have heard his forceful voice and witnessed his diligent exploration.
As the person in charge of several reliability engineering technology centers, he organized the reliability inspection of dozens of key projects of the General Armament Department and the Commission of Science, Technology and Industry for National Defense, which was well received by the national defense system and was praised as a "reliable reliability engineering expert".
In mid-May, 20001year, on the eve of being diagnosed with advanced cancer, the General Armament Department systematically carried out inspections of arms and services, including a high-tech project. The quality inspection team of a certain unit was not fully prepared and lacked reliable experts. When Yang Weimin heard about it, he thought it was suspicious to go through the motions. He roared in the office: "This is an irresponsible attitude towards the country!"
Yang Weimin always speaks loudly and is very excited. Several Beihang backbones present advised him: "Our center has done everything that should be done within the scope of its duties. The poor organization above has nothing to do with us. "
Yang Weimin burst into tears when he saw that everyone was not taking it seriously: "You can't just see your own clique, you should think from the height of national equipment. If their top management is not in place, we are obliged to do the work! "
Yang Weimin immediately reported to the relevant leaders and suggested adjusting the members of the inspection team. Finally, Yang Weimin personally led the team and organized three or four experts to enter the project site.
Help aerospace make contributions.
Yang Weimin's contribution to the space field is equally outstanding. He has always said that "aerospace is a family" and directly participated in and promoted the development of many aerospace models.
Shenzhou spaceship is the first manned spacecraft developed by the space system, which is of great significance. The probability of an accident should be controlled within one in ten million. How to verify such a small probability event? As early as a few years ago, Wang Yongzhi, chief designer of manned space system, discussed this issue with Yang Weimin. Yang Weimin immediately launched the research of "astronaut safety verification technology".
He invited airworthiness experts from China civil aviation, experts from Tsinghua University Institute of Nuclear Energy and reliability engineering experts from aerospace field to form a research group, and drew lessons from a series of experiences of safety accident requirements and control methods for passenger planes and nuclear power plants, and put forward safety verification ideas and analysis, experiments, demonstrations and other verification methods. Wang Yongzhi said with appreciation at the project review meeting: "This project is well done and provides ideas for our work."
After a lot of reliability work in shenzhou spaceship, Yang Weimin proposed "to be foolproof" and introduced the new reliability growth test of Beihang University. At his suggestion, 14 key equipment on Shenzhou-1 was sent to Beihang University for inspection in June, 1998, and it was found that two products, the infrared earth sensor and the liquid floating gyro, failed. After the successful recovery of Shenzhou I, Qi Faren, the chief designer and alumnus of Beihang University, immediately called Yang Weimin from the base and said gratefully, "Lao Yang, the recovery has just been successful! Thanks to your experiment, otherwise, you can't come back on the last day. "
A certain type of missile in China has repeatedly failed in the development process, which has delayed the progress. Yang Weimin was particularly anxious and offered to take part in this work. The director of the Second Artillery Model Office repeatedly expressed his feelings: "When there is a problem, I want to find Lao Yang." Because the missile uses a new engine, the comrades involved in the development lack experience in this field. Yang Weimin has set up several expert groups to guide the work. After his serious illness operation, a list of accident analysis experts was drawn up, and aviation experts were invited to participate in the work one by one.
In 2000, Yang Weimin came to the Fourth Institute of Aerospace for the first time and went deep into several remote ravine factories and research institutes for investigation. Surprised, he greatly appreciated the indomitable spirit of the comrades here under extremely difficult conditions. He saw that the metal shell of the solid rocket engine was a cylinder with a diameter of only 1 m, and a hole of several tens of centimeters was opened. A thin worker went in, dipped in toxic glue, painted the inner wall with glue, and glued the insulation layer by hand. If it is not pasted properly, the engine will burn through when working. "Such conditions and equipment how line? Quality inspection instruments are too backward! " After Yang Weimin returned to Beijing, he immediately reported to the leaders of the Science and Technology Commission and suggested that this problem should be solved as soon as possible.
At work, Yang Weimin is still an excellent "Bole". When developing a certain model in the Second Institute of Aerospace, Yang Weimin found that Chen Shinian, the chief engineer of the model, had great ideas on promoting quality and reliability. He was recommended as an expert when the Science and Technology Commission set up an expert group on quality and reliability. Therefore, Chen Shinian said many times: "Lao Yang found me."
Understand fame and fortune, clear your mind.
Yang Weimin strives for perfection in his work, but he is simple in his life. He often eats a bowl of egg noodles, wears a jacket worth several hundred yuan and rides a worn-out bicycle. He was visited by thieves in Beihang dormitory, but nothing was lost.
In recent years, all kinds of bonuses, evaluation fees and lecture fees he received were nearly 200,000 yuan, all of which were turned over to the department as a young teacher award fund. 1994, the Ministry of Aviation launched the "Aviation Gold Medal". Only two aviation enterprises with 560,000 employees and 654.38+10,000 scientific and technological workers won awards, each with a bonus of 654.38+10,000 yuan, which was not a small sum at that time. Song Jian, director of the State Science and Technology Commission, specially instructed Yang Weimin when awarding the prize: "Don't hand it in", and the department also said that it should follow the instructions of the leaders. But no one can beat Yang Weimin. He said, "The work is done by everyone. Please don't let me be divorced from the masses. "
He once spared a senior engineer twice, a professor twice and seven opportunities to go abroad with an open mind; The computer, camera and other prizes he won were used for collective needs; The project leader and the signature of the paper, he introduced the young people and stood behind himself.
There are certain labor scientific research committees. Yang Weimin doesn't advocate putting it into personal pockets alone, leading everyone to take the road of collective development. In the Ministry, Yang Weimin's allowance is only second-class; The school implements a post allowance and gives him a first-class merit of 50,000 yuan every year, but he said: "My old colleague only gets 30,000, and I only get 30,000." Ask the secretary to give the remaining 20 thousand to the department.
Yang Weimin has many rings of honor, but he always stays away from honor. The comrades of the general branch of the department reported the "May 1 ST" labor medal materials for him when he was on a business trip. After he came back, he had a quarrel with the comrades in the General Branch.
Under the influence of Yang Weimin, this department has formed an atmosphere of striving for fame and gain. Once, Professor Wang Deyan from an enterprise came to Beihang University to dig people and enthusiastically took Professor Wang on an inspection tour. For Professor Wang, the annual salary of this technically simple task is 3 million RMB, but Professor Wang refused. He said, "If you want to get rich and become a millionaire or a multimillionaire, Yang Weimin doesn't have the ability and conditions. He could have made a fortune a long time ago. But Yang Weimin said, what's the use of asking for so much money? What if you enjoy it? The cause of reliability cannot be separated from us! People of our age can understand. "
Mourning day, drizzle like tears; Pedestrians on the road want to die. Zhang, a doctoral student at Beihang University, opened a memorial hall for his beloved teacher online, which was welcomed by teachers and students, and various commemorative articles flocked to him:
"I don't want to be famous and make money all my life, but I hope the country will be rich and strong. It is your integrity and noble personality charm that makes me extremely sad about your departure. "
"The reliability cause you started has built the Great Wall of Steel for the national defense construction of the motherland." ……
Today, Yang Weimin's ashes are scattered inside and outside the Great Wall according to his wishes. The Great Wall, the symbol of the Chinese nation, has sown the sincere love and homesickness of Chinese children for the motherland here. Yang Weimin turned into spring mud here, continuing his lifelong affection for the Great Wall.
Come with a heart and go without a blade of grass. This is Yang Weimin. "The spirit of serving the people will last forever"-teachers and students of Beihang University have mentioned this sentence countless times. Yang Weimin left us not only the reliability cause he started, but also a valuable spiritual wealth.
■ Seeing that someone didn't take quality seriously, he burst into tears and personally led the team into the project site.
■ Song Jian asked him not to pay the bonus, but he insisted on paying 65,438+10,000 yuan to the department to reward young teachers.
He is terminally ill and works harder. The nurse said that it seems that work is his enjoyment.
■ On the Internet, his memorial hall became a famous column, and 6000 people visited and mourned in two months.
★ Delicious food
From 65438 to 0976, Yang Weimin went to the ultra-leftwing and served as the monitor of the cookhouse squad on a farm in the suburbs of Beijing. His cooking and steamed bread are still memorable. Yang Weimin worked out the relationship among temperature, fermentation quantity and fermentation time, drew a table and posted it on the wall for other comrades to compare. Yang Weimin's stomach only allows him to eat light food such as eggs and noodles, and he seldom has time to cook. But when it comes to cooking with colleagues, he is sober-headed: "You can't make seafood so delicious, I'll tell you …" In fact, Yang Weimin is good at dancing, swimming, ball games and playing the violin. If he has time for entertainment and exercise, his life should be colorful.
★ Heroes around you
20065438+020065438+0On the evening of February 2, Yang Weimin, who was in the late stage of pancreatic cancer, called Kang Rui, deputy director of the Department of Engineering Systems Engineering of Beihang University, to learn about the progress of scientific research. After putting the phone down, Kang Rui found that Yang Weimin, who had serious ascites and was maintained by 3 liters of nutrient solution every day, had been talking to himself for more than 40 minutes. The 6-year-old daughter asked him, "Who has been calling for so long?" Kang Rui said, "It's a sick grandfather." The child wondered, "Why are you talking so loudly when you are ill?" Kangrui blurted out, "Because grandpa is a hero."
★ The last sentence in life
On June 29th, 2002, the morning before Professor Yang Weimin's death, Yang Weimin called Wang Junqing, the head nurse of the special needs ward of Union Medical College Hospital. Yang Weimin, slim and panting, said intermittently, "I know I don't have much time. I have lived here for more than half a year, and your role looks like a soldier in the war. These soldiers you brought are excellent, and I thank them. You should take good care of them. "
This is Yang Weimin's way of caring for everyone around him at any time and place. He left the last words of his life to the nurse. After the head nurse came out, she ran to the dispensing room and cried.
