At present, the major state-owned enterprises under the jurisdiction of the Commission of Science, Technology and Industry for National Defense are basically not engaged in formalism in order to meet the inspection of leaders.

No one knows when Director Yang will suddenly appear in micro-suits, and no one is willing to touch this mold.

The leading cadres of the major factories and research units below all know that Director Yang is the same, and they only need to do their work well, which is the greatest respect and respect for Director Yang.

The pragmatic and rigorous work style of saying less and doing more has become the mainstream atmosphere in the circle of national defense heavy industry enterprises.

Although the iron rice bowl has been smashed, as long as you are dedicated and love your job, and work conscientiously and responsibly, your salary and benefits have more than doubled compared with before. As long as you have real talent and real learning, this iron rice bowl may become a golden rice bowl.

The separation of responsibilities between government and enterprises enables enterprises to fully release their potential and vitality in the process of operation and management.

Mechanism, a management system that can ensure the benign operation of state-owned enterprises, is what Yang Weiping attaches the most importance to.

He no longer engages in the kind of micro-service private visits that go to the following business units without doing anything. As long as he appears, there must be some business management, or technical innovation that needs to be implemented.

Regarding Director Yang's sudden arrival, Wang Chun had long been surprised.

Even if Director Yang does not come, Wang Chun is ready to draft a report and report to the Commission of Science, Technology and Industry for National Defense on the development process of the WS8 Kunlun engine.

Director Yang, who was wearing a Type 81 field trench coat, looked like a demobilized soldier who had retired from the field army and demobilized, but not like a senior member of the government and the opposition who was in charge of the development of China's national defense science, technology and industry, and the State Planning Commission.

He just smiled and nodded to Wang Chun to say hello, and then walked around the test platform carefully and carefully, while walking slowly, observing every part of the WS8 high-ducted turbofan engine on the test bench that had been running non-stop for more than 425 hours and 37 minutes, and occasionally stopping to listen carefully to the sound inside the engine.

The turbofans of large, medium and small thrust required by the fighters of the Huaxia Air Force have basically been solved at present. However, the high-thrust and high-ducted turbofans supporting the strategic air force and domestic civil aviation large passenger aircraft are still being verified.

Based on four WS8 Kunlun engines, the Yun-10 has been improved on the basis of the original design, using new aviation materials such as aluminum-lithium alloy, titanium alloy, and carbon fiber composite materials. It replaces the original conventional hard aluminum alloy.

Appropriate improvements were made to both the aerodynamic layout and the fuselage structure, and wind tunnel experiments were carried out. It borrows from the C5 and Boeing 747 in the United States and the Airbus A310 in Europe, combined with the thrust and thrust-to-weight ratio of WS8. The design has been re-optimized.

The extensive use of mainframe computers and personal computers has significantly improved the efficiency of the parallel engineering management mode, and accelerated the pace of improvement and development of Yun-10.

With the deep technical reserves of Lao Yunshi, he laid the foundation. The R&D progress of Xinyun 10 is naturally how fast and good it is. At present, it has entered the stage of production preparation. Mainly carry out process review, according to the new process, new standards, new technology test research, the preparation of various processes, management documents 39,931. Drawing of mold lines, fabrication patterns, tooling design and fabrication. Including the trial production of engine nacelles and engine hangings, etc.

"Director Yang, if nothing else, our WS8 can be finalized!" Wang Chun came to Yang Weiping's side and shouted loudly.

Accompanied by the roar of the engine "boom boom". Yang Weiping also said loudly: "You can consider conducting a small batch trial production first. There is still half a month to complete the production preparation work at the large aircraft factory, and the modification of the four-engine bombardment also needs to have ready-made engines. If the WS8 can't come out in time, the progress of the Yun-10 and the four-shot H-6 will definitely be affected. ”

"The molds and materials of the various parts manufacturing plants have been prepared for a long time, just waiting for the production plan to be officially issued. Wang Chun invited Yang Weiping to the computer room with a very good sound insulation effect, and personally made tea for Yang Weiping. While saying, "This order has to be made by you, Director Yang." ”

Yang Weiping stood in front of the color display screen and stared at the data and curves carefully for a while, and soon his eyes were sour by the scanning line that shook from time to time, he turned his eyes away from the display screen, pointed to the color display and said: "This thing has to be changed quickly, Changhong Electronic Picture Tube Factory has developed the color display of the plane right angle." The image is much more stable and clear than this old color display. I'll make a plan right away and give priority to all research institutes and laboratories first. ”

"That's a waste of the state's money!" Wang Chunzheng said: "In fact, if you get used to it, you don't have to worry about it, this kind of color display is much stronger than the previous black and white display." ”

"Of course, you have to save where you should save, but you can't save a penny where you should spend money. Yang Weiping rubbed his sore eyes, and said with a shameful face: "It's still that my work is not in place and meticulous, and this color display should be replaced as soon as possible." If you get used to this kind of display for a long time, your eyes will go wrong. ”

"Director Yang, our current working environment is superior enough. Seeing this, Wang Chun hurriedly comforted: "When I didn't have anything before, I didn't have to work all the way, but now it's air conditioning and anti-static carpets, and our computer room is more advanced than a hotel." ”

"In the past, our country was too poor, but now that the conditions are better, of course we have to improve. Yang Weiping said very seriously: "Improving the environment is not for enjoyment, but so that our scientific research workers can concentrate on their work without being distracted by various unfavorable environmental factors." This is a necessary measure to improve work efficiency. ”

Wang Chun said with emotion: "If we fail to produce results, we will really be ashamed." ”

"The No. 1 leader clearly put forward the principle that science and technology are the first vital force, and of course we must take this primary productive force as a top priority. Yang Weiping said: "Science and technology and education are the foundation of a country's development. If we fail to formulate corresponding policies and measures, and put them into practice, then we are no different from the past when we only knew that slogans were not pragmatic. ”

"China's scientific research work has such a pragmatic and wise leadership as Director Yang, which is really a blessing for us scientific and technological workers, a blessing for the country, and a blessing for the nation!" Wang Chun praised from the bottom of his heart.

"Hehe, I'm not as great as Elder Wang said. Yang Weiping smiled indifferently: "I am also a scientific research worker, no, some people in the southeast coastal provinces have already said that I am working for personal welfare!"

Wang Chunhuai couldn't help but scold angrily: "Do such people still want to use the same methods of the past four people and gangs to smear and attack Director Yang? They are simply pipe dreams! Don't say that if Wang Chun doesn't agree, all the scientific research workers in the whole country won't agree!"

"Don't talk about these uninteresting topics. Yang Weiping smiled disappreciatively: "Elder Wang, after WS8 Kunlun is finalized, do you have any other plans for the future?"

"Of course there is!" Wang Chun replied without hesitation: "The research plan for advanced turbine engine gas generators and the joint turbine advanced gas generator research plan are only the first step in the long march of thousands of miles.

After the technical maturity of WS6H1 core engine, we divided the original staff into three groups, Group A is specially responsible for the development of small turbine advanced gas generators for engines with an air flow of less than 2.27 kg per second, Group B is for the development of medium turbine advanced gas generators for turboshaft engines with an air flow of 4.53 kg per second, and Group C is for the development of large turbine advanced gas generators for axial flow and centrifugal blade machines with an air flow range of 6.8~13.6 kg per second.

At present, each of the three groups has developed a gas generator. Each includes a compressor, combustion chamber, turbine, shaft, bearing, power turbine and its accessories. The main focus is on component and gas generator performance, taking into account the durability and longevity of the engine, as well as reliability, maintenance and production processes and costs.

In addition, in addition to these three groups, a special assembly engineering team has been set up to combine the different gas generators developed by groups A, B and C with other advanced high and low pressure components to form a technical verification engine, and evaluate the technology of new core engines and high and low pressure components in a real engine environment. Focus on evaluating the durability of the structure.

Since the start of the experiments, we have continuously improved and modified the different verification machines. Strictly follow the guiding principles that advanced military engines must have high performance, high thrust-to-weight ratio, high reliability, long life, low fuel consumption, low signal characteristics, and low life-cycle costs. At present, through improvement and modification, the boost ratio of the engine 3-stage fan has reached about 4.0, the total boost ratio has reached 30~40, the turbine inlet temperature has been increased to 1850 degrees, and the thrust-to-weight ratio has reached 8.7~10.0. ”

"Well, very good!" Yang Weiping nodded with satisfaction: "Elder Wang, you are not satisfied with the success of WS6H1, but continue to make persistent efforts, and divide the specific work in the core machine plan in detail, which is very good, and I feel very gratified!"

As you just said, China's engine industry, compared with the advanced and perfect engine technology and industrial chain of industrially developed countries in Europe and the United States, is just a small step in the long march. There is still a long and arduous journey ahead of us.

The four major experimental work of component verification, rotor verification, full-Taiwan engine verification and durability verification must be carried out in a scientific and rigorous manner, and not a single screw nail will be missed!

"Please rest assured, Director Yang, we promise to keep your instructions in mind at all times!" Wang Chun nodded solemnly. (To be continued.) )
