Zhou Ding was holding the revised planning and design drawing of the Chengnan base in his hand, and when he heard the words, he immediately unfolded it on the table, and the planning and design of the Chengnan base was suddenly displayed in front of Zhang Haiping.

The design plan of the size of drawing zero is very large, and it is unfolded in front of Zhang Haiping, and the planning and design of the entire Chengnan base is displayed in front of Zhang Haiping's eyes.

This is not an aero-engine manufacturing base!

This is?

Zhang Haiping looked at this huge design plan, first hesitated, and then, a huge surprise!

Because, Zhang Haiping saw the airport on the design and planning drawing, the two runways of the airport are very conspicuous, in addition, the large factories in the factory area are much larger than the general plants, especially the largest plant, which should be the aircraft assembly plant.

This is the design plan of the aircraft manufacturing base!

Zhang Haiping quickly reacted, and his mood became excited again, and he said loudly: "Mr. Li, are you going to enter the aircraft manufacturing industry in the future?" ”

Li Tianfeng nodded and said, "I have such a plan." ”

Zhang Haiping said in surprise: "Mr. Li, that's great, our domestic aviation industry, our military, all need enterprises like you, I believe that in a few years, Tianfeng Technology Company in the field of aircraft manufacturing, will be as good as you in the field of aero engines." ”

Li Tianfeng said: "Minister Zhang, I have won the award." ”

Zhang Haiping was a burst of joy, a burst of excitement, an idea immediately came to Zhang Haiping's mind, Zhang Haiping said: "Mr. Li, our current UAV project, I have a headache, now it's okay, you will enter the field of aircraft manufacturing in the future, the UAV project has a way out." In case we don't succeed, you can take over the baton and continue the development of this project. ”

Sure enough, as Zhang Haiping said, with the death of the military's drone project, the project was handed over to Tianfeng Technology Company. Tianfeng Technology Company entered the field of aircraft manufacturing, and the first product was a drone, a very good drone, of course, this is a later thing.

Zhang Haiping in Tianfeng Technology Co., Ltd., can be said to have gained a lot, surprises, not only saw the design technical outline of the turbofan 25 engine, the design of the turbofan 25. Very excellent, very advanced, gave Zhang Haiping a huge surprise.

In addition, Zhang Haiping was even more surprised and excited to learn that Tianfeng Technology Company would enter the field of aircraft manufacturing, and even Zhang Haiping could imagine that Tianfeng Technology Company would be in the future. We will definitely be able to develop and build a very good aircraft.

Zhang Haiping happily returned to the capital and took it with him. In addition to the great surprises and gains, there was also a technical outline of the design of the turbofan 25 engine.

When he returned to the capital, Zhang Haiping immediately reported to the main leaders of the military, and when he heard such a report, the military leaders were overjoyed and instructed Zhang Haiping. Personally follow the design and development of the turbofan 25 engine.

The head of the military stated that the turbofan 25 project, one of the most important projects of the military at present, is strongly supported by the military, and the green light is given all the way.

There is support from above. In addition, it is the research and development and manufacturing of such an advanced engine, Zhang Haiping is full of enthusiasm and enthusiasm, and soon organized a group of experts to review the design and technical outline of the turbofan 25 engine.

The judging meeting was held in a low-key and grand manner in Beijing.

It is said that it is low-key, because it is confidential, and no media is required to participate, and there are very few people who know about this matter, and it is controlled within a small range, and it is said that it is grand, because not only are there many big military leaders participating in the review meeting, but there are also more experts who participate in the review meeting.

Dozens of experts, experts in various aspects of the domestic aero engine field, at the review meeting, this turbofan 25 design technical outline was displayed in front of everyone, and many old experts were excited.

One of them, a white-haired, retired veteran expert from a domestic aero engine research institute, said tremblingly: "I didn't think that we would have such an advanced engine in China!" ”

Another expert wearing reading glasses also said excitedly: "Yes, in our lifetime, we can actually see such an advanced engine, we are satisfied, and we are content to enter the loess!" ”

At the review meeting, everyone spoke highly of this engine, and unanimously passed the review, which was basically not a review meeting, more like a praise meeting, and even an old expert had to hurriedly take out the medicine he carried with him because of excessive excitement, and hurriedly ate two tablets.

At the end of the review meeting, a senior expert even excitedly shook Zhang Haiping's hand and said excitedly: "Minister Zhang, we must spare no effort to promote this engine, with such an advanced aero engine, we can also raise our eyebrows!" ”

Zhang Haiping said again and again: "Certainly, definitely, our military must vigorously support the research and development of the turbofan 25 project, and we will successfully develop and manufacture this engine." ”

The review meeting was successfully introduced, and Tianfeng Technology Company also received an official notice from the military that the turbofan 25 engine can enter the design stage.

In addition, in addition to the official notice from the military, a huge amount of research funds also entered the account of Tianfeng Technology Company a few days later, and the scientific research funds amounted to billions of dollars, which made Li Tianfeng a surprise, which shows the importance and support of the military for this project.

At the beginning of December, the turbofan 21 engine basically completed the comprehensive design and began to enter the trial production and process verification stage of parts, which was about a month earlier than Li Tianfeng originally expected.

Immediately after, the design of the turbofan 25 engine began to start, and immediately entered the comprehensive design stage, thousands of designers of Tianfeng Technology Company, after completing the design of the turbofan 21 engine, immediately began to enter the design of the turbofan 25 engine.

The design and development of the turbofan 25 engine was carried out by Sun Xiaoping, Sun Xiaoping was the chief designer of the turbofan 25 engine, and Qiu Wenan was the deputy chief designer.

The turbofan 25 engine is the same as the turbofan 21 engine, and the core part adopts the second-generation core machine technology of Tianfeng Technology Company, but the design of the core machine is changed to a certain extent, and the design of the core machine part basically adopts the enlarged size design.

The turbofan 25 engine has a maximum thrust of about 36,000 pounds, which is basically three times the thrust of the turbofan 21 engine, and the size of the core part of the turbofan 25 engine is larger than that of the turbofan 21 engine.

For example, the turbo of the turbofan 25 engine is significantly larger than that of the turbofan 21 engine, but the structure and shape are basically similar.

The combustion chamber part and the compressor part are basically the same, and the design and structure of the two are basically similar, but the size of the parts of the turbofan 25 engine is significantly larger.

Of course, the fan part is different, because the turbofan 21 engine is a large channel than the turbofan engine, although the compressor, combustion chamber, and turbine part are relatively small in size, but the fan part is indeed large, much larger than the fan of the turbofan 25 engine.

The turbofan 25 engine is a turbofan engine with a small channel ratio, and the maximum diameter of the fan is only 8 or 900 millimeters, while the fan diameter of the turbofan 21 engine is more than 1.3 meters.

Thousands of designers in the aero engine R&D center, under the leadership of Sun Xiaoping, carried out the comprehensive design of the turbofan 25 engine, and Zeng Qinghai took the process technology department as the leader and the process technicians of the subordinate workshops as the main force, and began the comprehensive compilation of the processing process regulations for each part of the turbofan 21 engine.

Tianfeng Technology Company has a lot of designers, process technicians are also a lot, Zeng Qinghai will turbofan 21 engine parts classification, assigned to the subordinate workshops, began the preparation of process regulations, important and key parts of the process regulations, arranged senior process technicians, or process masters are personally responsible.

Among the designers, there are design experts, process technicians and process experts, which is the internal assessment of Tianfeng Technology Company, process experts, the level is above the professor-level senior engineer, the entire Tianfeng Technology Company, so far, can win the title of process experts can only be worthy of more than ten people.

In addition to more than 20,000 front-line manufacturing workers, there are about 7 or 8,000 designers, process technicians, and all kinds of technical personnel.

With strong technical force, Li Tianfeng dared to start the R&D and manufacturing of turbofan 21 engine and turbofan 25 engine at the same time, both of which were carried out in an orderly manner and progressed smoothly.

Sun Xiaoping is responsible for the design work, Zeng Qinghai is responsible for the process and technical work, and Li Tianfeng should be the busiest, taking both into account, not only to guide the design of the turbofan 25 engine, but also to guide the preparation of the processing technology specifications of the parts of the turbofan 21 engine.

However, hard work is hard work, Li Tianfeng is full of energy, and the sense of accomplishment in his heart is also full.

In addition, several deputies under Li Tianfeng are also very effective, Sun Kang is in charge of manufacturing, Xu Lilong is responsible for the daily management of the company, Zhang Can is responsible for the Qingshi manufacturing base, and Zhou Yiding is responsible for the construction of the Chengnan base.

Although it is a little hard, it is also happy and full of rewards.

At the end of December, it is the time of the year's inventory and harvest, and the financial department of Tianfeng Technology Company is the same, and several financial executives are taking stock of this year's financial work.

One of the financial directors is taking several of his subordinates to make statistics on this year's sales collection, and it can be seen from everyone's excited look that this year's sales collection must be good.

Tianfeng Technology's sales orders this year have signed 100 billions of yuan, almost approaching the 200 billion mark.

So many orders have been signed, there are a lot of engines delivered every month, and there are a lot of monthly sales collections, and the personnel of the finance department have to collect statistics every month.

It is the end of the month again, and it is the end of December, and the financial staff of Tianfeng Technology Company, as usual, are carrying out the collection statistics.

"My God, head, you see, this can't be a mistake by a colleague in the marketing department, why are there so many return tickets in December, you look at these bills, it's unbelievable!"
