Wang Ruobing seemed to feel the pressure in Li Tianfeng's heart and said considerately: "Tianfeng, it's okay, don't put too much pressure on yourself."

Li Tianfeng smiled and comforted: "Ruobing, it's okay, only with pressure can you be motivated. This time we must make a fuss. Before the end of the year, our two engines will definitely start mass delivery."

Wang Ruobing gently hugged Li Tianfeng, "Tianfeng, why don't I talk about you privately and ask Uncle San to call AVIC Group."

Li Tianfeng said: "Ruobing, there is no need for the time being. I have confidence in myself. I can withstand this pressure. Believe me, I can do it!"

Wang Ruobing nodded and felt a little relieved.

………

Feeling the pressure in his heart, Li Tianfeng knew that he had to work hard to speed up the development progress, so Li Tianfeng and Wang Ruobing did not stay in the capital again. Li Tianfeng returned to Songzhou and entered the working state on the day he returned to Songzhou.

When returning to Tianfeng Technology Company, Li Tianfeng's first thing was to go to the production and processing site and check the processing of the parts of the turbofan 16.

Most of the parts of the turbofan 16 engine have been fully verified by the process and have basically been finalized. In addition, they have obtained a design certificate, so major changes are not possible in the design, so most parts have begun to enter small-scale production.

A small number of parts that require further process verification are continuing to undergo verification processing. However, for such verification processing, the process will be finalized without two batches of processing.

With the complete design of the "tfws002" engine, all parts of the "tfws002" type engine have also begun to enter the process verification and the test stage of each part.

Fortunately, the "tfws002" type engine and the core engine of the turbofan 16 engine are partly common, the number of redesigned parts has been greatly reduced, and various types of verification work has also been greatly reduced. I believe that the verification stage will not be very long.

At the production and processing site, Li Tianfeng watched it for a long time and looked very seriously. Seeing that everything was basically normal, Li Tianfeng felt a little relieved.

At the same time, Li Tianfeng also went to the new factory, most of which have started construction, and a small number are still undergoing equipment installation and debugging. Judging from the progress, it will be a matter of time before full construction starts.

Each of these new factories has an area of ​​tens of thousands of square meters. One such factory is a large processing workshop, which not only has dozens of technicians, but also has a scale of two or three hundred front-line workers.

Hu Xiao is already formulating a talent recruitment plan again, and will recruit nearly a thousand front-line technical workers again, as well as some technical talents, as well as some high-end technical talents.

The research and development and manufacturing of aircraft engines are technology-intensive and require a large number of technical talents. Although Li Tianfeng has good technical skills, he cannot do it himself. He is more of a role as a navigator and helmsman. The key is to form a strong technical team.

High-end technical talents, the group of postdoctoral and doctoral students introduced last time, performed very well and have begun to take on some more important technical positions. This time, Li Tianfeng instructed Hu Xiao to prepare to recruit a group of postdoctoral and doctoral students again.

After looking around the major workshops, Li Tianfeng finally entered the newly established International Industry and Trade Branch. The company's main business is parts processing, and its customers are mainly some aviation industry enterprises, including some other manufacturing enterprises.

International Industry and Trade Branch, two large factories are arranged side by side. Each factory has an area of ​​more than 10,000 square meters, which is basically the same as other newly built large factories. From the appearance, the style is basically the same, the interior is basically the same, and it is also built at a high standard.

I just entered the International Industry and Trade Branch. It was quite coincidental that I happened to meet Zhang Can. Now Zhang Can is the manager of the International Industry and Trade Branch. He has nearly a thousand people, two or three billion yuan in output value.

Zhang Can said in surprise: "Boss, you are here."

Li Tianfeng said: "Zhang Can, the factory is clean, neat and orderly, and the management is pretty good."

Zhang Can smiled happily and said, "Boss, the current international industry and trade branch has entered normal production, and it is a busy scene."

Li Tianfeng nodded with satisfaction and said, "Zhang Can, let's take me to see your International Industry and Trade Branch."

Under the leadership of Zhang Can, Li Tianfeng looked around the entire International Industry and Trade Branch. Li Tianfeng was quite satisfied. This business is becoming bigger and bigger and stronger. Now that it is divided separately, the space for development will be greater in the future.

When leaving the International Industry and Trade Branch, Li Tianfeng patted Zhang Can on the shoulder and said, "Zhang Can, work hard, work hard, and strive to do something big."

Zhang Can was a little excited. Now Zhang Can is successful in his career and young and promising. Looking back on the past, Zhang Can often be glad to be how wise he was to follow Li Tianfeng. Otherwise, how could he achieve such achievements today? Maybe he would still be a young technician from the e-factory.

...

In the office.

Li Tianfeng spent several days to carefully read the design drawings of the main and important parts of the "tfws003" turbofan engine with a thrust level of 10,000 pounds, and of course, he also looked at the overall design aspect.

In general, Li Tianfeng is quite satisfied, but some places still need to be designed and improved. Li Tianfeng marked and pointed out these places one by one.

Li Tianfeng naturally attaches great importance to this engine. Don’t look at the small thrust of the engine, and the volume and weight are much smaller than the previous two engines, but it is equally advanced and has excellent overall performance.

Picking up the phone, Li Tianfeng called Sun Xiaoping over. In the office, Li Tianfeng pointed out the problems in the design of this engine and the areas that need improvement and improvement.

After talking about this, Li Tianfeng said: "Mr. Sun, according to these requirements, improve and improve again, and then organize everyone to review, three cobblers, one Zhuge Liang, and brainstorm to strive to design this engine better."

Sun Xiaoping said: "Boss, you must, you must review the picture numbers one by one."

Li Tianfeng said: "For some key and key parts, when reviewing designs, please ask me to participate if necessary."

…………

In the intense work, life always passes faster. It’s been a month since Li Tianfeng came back from the capital, and it’s also June and early summer weather. It’s lush and full of vitality.

The same is true for Tianfeng Technology Company, full of vitality. Not only is every new factory fully put into use. Not long ago, thousands of new employees joined the large team of Tianfeng Technology Company, including several postdoctoral fellows and more than twenty doctors.

The turbofan 16 engine has not been completed for a 150-hour long test. It has not been long since the 300-hour long test was completed. Now, the 300-hour long test has been completed.

Li Tianfeng is coming back from the assembly workshop. Just now, Li Tianfeng personally inspected the engine situation after completing the 300-hour long test.

Li Tianfeng looked at it carefully and was very professional. The engine was completed in a 300-hour long test, the engine was decomposed, and the parts were cleaned, which looked very convenient.

Li Tianfeng was very satisfied with the situation of each part and the test run of the engine. Even after 300 hours of long test, there was no problem with the engine, which was very normal.

After watching the turbofan 16 engine that had been tested for 300 hours, Li Tianfeng thought to himself that two turbofan 16 engines might be assembled again.

The turbofan 16 engine, which has been tested for 300 hours, and the two turbofan 16 engines that Li Tianfeng is now considering assembly, are both prototypes.

The so-called prototype is the first batch of engines for testing and test flights made according to design drawings during the development of the new machine.

In the new machine trial production factory, the batches of prototypes are usually named 00 batches or 0 batches. The number of prototypes is determined according to the new machine category and development needs. The number of newly developed aircraft engines is generally 3 to 5 prototypes, some of which are used for ground trial run tests, and some are used for test flight tests.

By making design changes to the shortcomings in the design exposed by the prototype during test and test flight, the design of the new aircraft must meet the original design indicators and requirements.

However, judging from the ground interview situation of the turbofan 16 engine, everything is normal and fully meets the original design indicators and requirements. As for whether the test flight verification also fully meets the design requirements, this requires test flight verification.

After all, there are more situations and various factors in the field test. If the field test test is successfully passed and the engine fully meets the design requirements, you can apply for a production license to conduct the formal production of the engine.

On the contrary, if there is a problem with the engine test flight test, an analysis should be carried out to find out the reasons for the failure, and design changes should be made to the shortcomings of the prototype in the test and test flight to make the new aircraft design meet the original design indicators and requirements.

However, if you really need to make major design changes to the turbofan 16 because of the test flight failure, it will be really troublesome.

To make design changes, some parts have to be redesigned, and these new parts have to be verified and tested. After these work is completed, the new parts are installed on the engine, and the engine has to be verified and tested, etc., which is very troublesome and time-consuming.

In the aviation industry, especially the domestic aviation industry, such things are often found. Because of the continuous and repeated design changes, every newly developed aviation engine in China has to undergo many twists and turns and goes through a long cycle. Often, it takes several years or even more than ten years from the beginning of design to the final development of an engine.

In addition, it may also face the failure of research and development. The senior executives of AVIC Group are well aware of this, so they are not optimistic about Tianfeng Technology and are preparing to cooperate with the Ge side. Wanyifeng Technology's development failed and can also be equipped with Ge engines.

Fortunately, the turbofan 16 series of ground interviews were very smooth, and they only waited for flight tests and verification. If they passed smoothly, there was no need to make design changes. They could immediately perform production licenses, which would greatly shorten the development cycle. Otherwise, it would take a lot of time.

If it is really because the test flight fails, repeated design improvements and a series of tests and verifications will take a lot of time and cannot enter formal production before the end of the year, which means that it will not be delivered to COMAC's engines before the end of the year.

Li Tianfeng thought to himself, it seems that these two prototypes used for test flights must start assembly immediately, and seizing all the time is the king.

Li Tianfeng knew that the warehouse should be enough to assemble the two prototypes again. Considering that the two prototypes were to be assembled immediately, Li Tianfeng went to Sun Kang's office.

It seemed that Sun Kang was working hard. When he saw Li Tianfeng coming in, he immediately put down his pen and stood up, "Tianfeng, why are you free to come here? Is there something wrong?"

There are no outsiders in the office, and Li Tianfeng seems to be more casual, "Brother-in-law, I really have something to ask you for. Check the number of parts of the turbofan 16 engine in our warehouse, and whether it is enough to assemble the two turbofan 16 engines."

Sun Kang said: "Tianfeng, judging by how you are, you have relatively urgent requirements for assembling these two prototypes. I'll call you right away."

After saying that, Sun Kang picked up the phone on his desk and called the warehouse. Sun Kang was in charge of production, and the warehouse was within Sun Kang's jurisdiction.

The phone call was called, and it would take some time for the official results, so the two of them chatted together, waiting for the warehouse reply while chatting.

The response from the warehouse is quite fast, because the warehouse has an advanced computer management system. After checking it on the computer, it is clear that the phone call came in just a few minutes.

"Mr. Sun, if two turbofan 16 prototypes are assembled, the second engine will lack three parts with the figure number. These three parts are the first-stage turbine guide blade missing two pieces, one missing one compressor spacer, and one missing one turbine bolt."

Li Tianfeng thought there should be enough parts to assemble two prototypes, but he didn't expect that the second one still lacks these three parts.

In fact, it is not a big deal for Li Tianfeng. It is normal for Li Tianfeng to have so many parts of the engine, and Li Tianfeng's main energy is on technology.

Sun Kang said: "Tianfeng, these three parts are missing when assembling the second engine. It seems that they can only be put into production immediately and strive to produce it as soon as possible."

Li Tianfeng asked: "Brother-in-law, how long will it take to produce these three parts?"

Sun Kang said: "We have roughly processed semi-finished products for spacer rings and turbine bolts. If they are produced immediately, they will take about five days to complete 24 hours and three shifts. However, the turbine guide blade process is relatively complicated, and it is afraid it will take half a month to produce it."

If you wait for another half a month, Li Tianfeng will definitely not be able to wait!

I can't wait! Li Tianfeng frowned and thought.
