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

Li Tianfeng smiled and said with relief: "Ruobing, it's okay, there is pressure to have power, this time we must fight for breath, before the end of the year, our two engines will definitely start to be delivered in batches." ”

Wang Ruobing hugged Li Tianfeng gently, "Tianfeng, why don't I talk to the third uncle about you in private, and ask the third uncle to make a call to the AVIC Group." ”

Li Tianfeng said: "Ruobing, there is no need for the time being, I have confidence in myself, this pressure, I can completely bear it, believe me, I can do it!" ”

Wang Ruobing nodded, feeling 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 anymore, Li Tianfeng returned to Songzhou, and entered the work state on the day he returned to Songzhou.

Back at Tianfeng Technology Company, the first thing Li Tianfeng did was to go to the production and processing site and watch the processing of various parts of the turbofan 16.

Most of the parts of the turbofan 16 engine have been fully verified, the process has basically been finalized, and the design certificate has been obtained, and it is impossible to change the design, so most of the parts have begun to enter small batch production.

A small number of parts that still need further process verification are continuing to be verified, but the process will be finalized without two batches of processing.

With the completion of the comprehensive design work, the parts of the "TFWS002" engine have also begun to enter the process verification and test stage of each part.

Fortunately, the "TFWS002" engine and the turbofan 16 engine core are partially common, and the number of redesigned parts is greatly reduced. The verification work of all kinds has also been greatly reduced, and it is believed that the verification phase will not be very long.

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

Meantime. Li Tianfeng also went to the new plant, most of these new plants have started, and a small number of them are still installing and debugging equipment.

Each of these new factories covers an area of tens of thousands of square meters, and one such plant is a large-scale processing workshop, with dozens of technicians. And the number of front-line workers has also reached two to three hundred.

Hu Xiao has been formulating a talent recruitment plan again, and will recruit nearly 1,000 front-line skilled workers again, as well as some technical talents, as well as some high-end technical talents.

The R&D and manufacturing of aero engines are technology-intensive and require a large number of technical personnel. It is more about playing the role of navigator and helmsman, and the key is to build a strong technical team.

High-end technical talents. The batch of postdocs and doctors introduced last time were very good and had begun to be qualified for some more important technical positions, and this time, Li Tianfeng instructed Hu Xiao to prepare to recruit a group of postdocs and doctors again.

The major workshops took a look. Satisfied, Li Tianfeng finally walked into the newly established international industry and trade branch, the company's main business is the processing of parts, its customers are mainly some aviation industry enterprises, but also some other manufacturing enterprises parts processing.

International Industry and Trade Branch. Two large factories side by side, each plant area is more than 10,000 square meters, and other new large-scale factories are basically the same, from the appearance, the style is basically the same, the interior is basically the same, and it is also a high-standard construction.

Just entered the international industry and trade branch, and it was a coincidence that I happened to meet Zhang Can, who is now the manager of the international industry and trade branch, with nearly 1,000 people under his hands, and an output value of more than 2 or 300 billion.

Zhang Can said in surprise: "Boss, you're here." ”

Li Tianfeng said: "Zhang Can, the inside of the factory is clean, neat and orderly, and the management is not bad." ”

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

Li Tianfeng nodded with satisfaction and said, "Zhang Can, go, take me to see your international industry and trade branch." ”

Li Tianfeng, under the leadership of Zhang Can, looked around the entire international industry and trade branch, Li Tianfeng was more satisfied, this business, is getting bigger and bigger, stronger and stronger, now it is divided separately, and the future development space will be greater.

When leaving the International Industry and Trade Branch, Li Tianfeng gently patted Zhang Can's shoulder and said, "Zhang Can, work hard, work hard, and strive to do a great career." ”

Zhang Can was a little excited in his heart, the current Zhang Can can can be regarded as a successful career, young and promising, recalling the past, Zhang Can often celebrated how wise he was to follow Li Tianfeng, otherwise, where is there such an achievement today, maybe he is still a small technician in Factory E.

……

In the office.

Li Tianfeng spent several days of hard work to carefully read the design drawings of the main and important parts of the turbofan engine with a thrust level of 10,000 pounds of the "TFWS003" type, and of course, also looked at the overall design.

On the whole, Li Tianfeng is quite satisfied, but there are still some places that still have to be improved and perfected, and Li Tianfeng marked and pointed out these places one by one.

For this engine, Li Tianfeng naturally attaches great importance to it, don't look at the small thrust of this engine, the volume and weight are also much smaller than the previous two engines, but the same advanced, comprehensive performance is also very good.

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

After talking about this, Li Tianfeng said: "Mr. Sun, in accordance with these requirements, improve and perfect again, and then organize everyone to review, three stinkers, top one Zhuge Liang, brainstorming, and strive to design this engine more excellent." ”

Sun Xiaoping said: "Boss, definitely, must be reviewed one by one." ”

Li Tianfeng said: "For some key and key parts, when the design review, if necessary, I will also participate. ”

…………

In the midst of intense work. The days always pass relatively quickly, seeing that Li Tianfeng has been back from the capital for a month, and the time has also entered June, the weather in early summer is lush everywhere and full of vitality.

The same is true for Tianfeng Technology. Full of vitality, not only each new plant is fully put into use, but also a talent recruitment not long ago, and thousands of new employees have joined the team of Tianfeng Technology Company, including several postdoctoral fellows and more than 20 doctors.

The turbofan 16 engine, after completing 150 hours of sustained testing, did not take long to enter the 300-hour long test, and now. The 300-hour long test has also been completed.

Li Tianfeng is returning from the assembly workshop. Just now in the assembly workshop, Li Tianfeng personally looked at the engine situation after completing the 300-hour long test.

Li Tianfeng looked more carefully, and was also very professional, the engine was completed in 300 hours, the engine was decomposed, and the parts were cleaned cleanly, which looked very convenient.

The condition of each part, the test run of the engine. Li Tianfeng was very satisfied, even after 300 hours of long trials. There was no problem with the engine, it was very normal.

After looking at this turbofan 16 engine that has been tested for 300 hours, Li Tianfeng thought in his heart that maybe he would have to assemble two turbofan 16 engines again.

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

The so-called prototype. It is the first batch of engines for test and flight test built according to the design drawings during the development of the new aircraft.

In the prototype factory, the batch of the prototype is usually named batch 00 or batch 0. The number of prototypes is determined according to the type of new machine and the development needs. The number of prototypes of newly developed aero engines is generally 3~5 units, some of which are used for ground test test and some for flight test.

Design changes were made to the deficiencies in the design of the prototype that were exposed during tests and flight tests. Make the design of the new machine meet the original design indicators and requirements.

However, judging from the ground test of the turbofan 16 engine, it is normal and fully meets the original design indicators and requirements, and as for whether the test flight verification is also fully in line with the design requirements, this needs to be tested for flight verification.

After all, the field flight test, facing more conditions and various factors, if the field flight test is also smooth, the engine fully meets the design requirements, then you can also apply for a production license, the formal production of the engine.

On the contrary, if there is a problem in the flight test of the engine, it is necessary to analyze and find out the reasons for the failure, and make design changes to the deficiencies in the design exposed in the test and flight test of the prototype, so that the design of the new aircraft can meet the original design indicators and requirements.

However, if it is really necessary to re-design the turbofan 16 because of the failure of the test flight, it will be really troublesome.

To make design changes, some parts have to be redesigned, and these new parts have to carry out a series of verification and tests, and after these work is completed, the new parts are installed on the engine, and the engine has to carry out a series of verification tests and test flights, etc., which is very troublesome and time-consuming.

In the aviation industry, especially in the domestic aviation industry, such things are often there, because of the continuous, repeated design changes, so each new domestic aero engine, to carry out a lot of twists and turns, but also to go through a long cycle, often an engine from the beginning of the design to the final development of success, often after several years, or even more than ten years.

In addition, it may also face development failure, and the senior management of AVIC Group is well aware of this, so they are not optimistic about Tianfeng Technology Company and are ready to cooperate with GE, in case the development failure of Tianfeng Technology Company, it can also be equipped with GE engines.

Fortunately, the turbofan 16 series of ground test vehicles are very smooth, only to be tested and verified again, if it is also smooth, then there is no need to make design changes, and the production license can be carried out immediately, which will greatly shorten the development cycle, otherwise, it will consume a lot of time.

If it is really because the test flight is unqualified, it will take a lot of time to carry out repeated design improvements and a series of tests and verifications, and it will not be able to enter formal production before the end of the year, which means that it will not be possible to deliver the COMAC engine before the end of the year.

Li Tianfeng thought in his heart, it seems that these two prototypes used for test flights have to start assembling immediately, and it is the king to hurry up and seize the time.

Li Tianfeng knew that the total number of parts in the warehouse should be enough to assemble the two prototypes again, and considering that the two prototypes would be assembled immediately, Li Tianfeng went to Sun Kang's office.

It seemed that Sun Kang was immersed in office, and when he saw Li Tianfeng coming in, he immediately put down his pen and stood up, "Tianfeng, why do you have time to come here, there is something?" ”

There were no outsiders in the office, Li Tianfeng seemed more casual, "Brother-in-law, I really have something to do with you, check the number of parts of the turbofan 16 engine in our warehouse, whether it is enough to assemble the number of parts of the two turbofan 16 engines." ”

Sun Kang said: "Tianfeng, seeing you like this, you are still in a hurry to assemble these two prototypes in terms of progress, so I will call immediately." ”

After speaking, Sun Kang picked up the phone on the desk and made a call to the warehouse. Sun Kang is in charge of production, and the warehouse is within Sun Kang's jurisdiction.

The call went out, and the official result would definitely take a little time, so the two chatted together, chatting while waiting for a reply from the warehouse.

The reply from the warehouse is also relatively fast, because the warehouse has an advanced computer management system, and the computer is clear, and the phone call comes in just a few minutes.

"Mr. Sun, if you assemble two turbofan 16 prototypes, the second engine assembly will be missing three parts with drawing numbers, these three parts are the first stage turbine guide blade is missing two, the compressor spacer ring is missing one, and the turbine bolt is missing."

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

In fact, Li Tianfeng can't be blamed, there are so many parts of the engine, and Li Tianfeng's main energy is on technology, and it is normal for there to be a small deviation.

Sun Kang said: "Tianfeng, the assembly of the second engine lacks these three parts, and it seems that it can only be put into production immediately, and strive to produce it as much as possible." ”

Li Tianfeng asked, "Brother-in-law, how long will it take for these three parts to be manufactured?" ”

Sun Kang said: "We have semi-finished products that have been rough-processed for spacers and turbine bolts, and if they are produced immediately, they will work in three shifts 24 hours a day, about five days, but the turbine guide blade process is more complicated, and it will take half a month to produce it." ”

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

I can't wait! Li Tianfeng thought with a frown.

………

Today's two watches, the second one is sent! (To be continued......)
