As soon as he heard this voice, Tang Fei secretly rejoiced in his heart, he had been waiting for this voice to sound for a long time, and he had been looking forward to its appearance, and now it had finally appeared.

Sure enough, as Tang Fei expected, this is the voice of the system reminder of the completion of the task of the drone military.

"Ding, mission completed, please pay attention to the host to check ......"

After hearing such a voice, Tang Fei originally walked towards the outside of the office, stopped abruptly, turned around and sat down on his wide and comfortable boss chair, and immediately opened the system to check the system's taskbar.

Originally, there were two tasks waiting to be completed in the task bar of the system, one of which was the UAV military project, and the other was the main mission of the EMU. The first two steps of this main quest have been completed, and the third step is waiting to be completed.

The status of the drone's military project task is displayed as completed, and the reward has also arrived, in the gold coin column of the system, there were only 500 gold coins, but now it has become 3000 gold coins, just now Tang Fei also heard the sound of the crisp gold coins arriving in the account.

Great, mission accomplished!

There was no one else in the office, only Tang Fei alone, and he didn't have to pay attention to his boss image, Tang Fei was so excited that he waved his fist in the air, and thought happily, Great, this task is complete!

That's really good news, it's already 3,000 gold.

The system upgrade requires 10,000 gold coins, and now it is a big step towards the upgrade, as long as the first EMU gets off the train, this will have enough gold coins for the system upgrade.

Looking at the 3,000 gold coins in the gold coin column of the system, and then looking at the task bar of the system, Tang Fei thought in a good mood, yes, go to the Red Star Factory to take a look at the assembly of the first EMU, and now its assembly has come to an end.

At the same time, thousands of miles away in the capital.

Just now, the military has officially completed the establishment of the UAV project, and on the UAV project approval book, Tang Guoqiang wrote his name on behalf of the military.

On this project approval document, it is also stamped with the bright red seal of the military. Tang Guoqiang himself was also satisfied, looked at the project proposal, and thought in his heart that the UAV was officially approved, which is very beneficial to the future work of the UAV.

The military has established a project, and many resources will be closer to the UAV, and the military will also pay more attention to the trial production of this UAV, and do a better job in escorting this UAV, so as to create a superior production and manufacturing environment for it.

。。。。。。。。。

Tang Fei went to the Red Star Factory.

Concerned about the assembly of the first EMU in his heart, Xu Guangming drove directly to the gate of the assembly workshop of the Red Star Factory, and after getting off, Tang Fei strode into the production site of the assembly workshop, and walked towards the first EMU with familiarity.

What is the most conspicuous thing in the huge assembly workshop? It must be this EMU, like a dazzling star, quietly parked on the standard rails in the assembly workshop.

The bullet-shaped front of the car, with a beautiful streamlined shape and white as the main color, is now basically assembled, but some finishing touches are being carried out, and the whole effect has been fully demonstrated.

This train looks even more beautiful than the original three-dimensional design, and its appearance is even higher, which immediately attracted Tang Fei's attention.

Accompanying Tang Fei, even Xu Guangming, who had always spoken little, couldn't help but say, "Boss, this EMU is really beautiful." ”

He can also be regarded as watching the assembly of this EMU gradually completed, because every time Tang Fei came to the Red Star Factory to check the assembly progress of this EMU, Xu Guangming basically accompanied him. From the beginning of the car body to the present, he didn't know how many times he had accompanied Tang Fei, watching this EMU be assembled little by little, and displayed in front of him little by little.

Tang Fei was very satisfied, and invisibly quickened his pace and walked towards this EMU.

It has a total of eight cars, and the eight cars are parked on the standard rails in the assembly workshop, and the total length of the long train is almost the same as the length of the assembly plant of the Red Star Factory, Tang Fei saw that there were many people at the front of the locomotive, including Xie Zhenhua. So, Tang Fei strode in the direction of the front of the car.

Seeing Tang Fei coming over, Xie Zhenhua seemed to be very happy, and immediately said loudly with joy: "Brother, you are here, just in time, our first train is basically assembled, and only some finishing work will be completed in the next few days." ”

Tang Fei said loudly: "Great, Lao Xie, we have been looking forward to it for so long, this day is coming soon." ”

Whether it's Tang Fei or Xie Zhenhua. Everyone is looking forward to it day and night, hoping that the EMU will complete the vehicle assembly as soon as possible, and get off the train as soon as possible.

Xie Zhenhua was followed by a number of middle and high-level executives of the Red Star Factory, and their eyes were also full of joy, which was enough for everyone to be very happy.

Xie Zhenhua briefly introduced the vehicle assembly of the first EMU to Tang Fei. Why is it a simple introduction? Because Tang Fei has been relatively diligent in the past few days, and he is relatively clear about the whole vehicle situation of the EMU, Xie Zhenhua only needs to make a brief report.

After introducing the current vehicle assembly of this EMU, Xie Zhenhua invited with great interest: "Let's go, let's get on the train and have a look." ”

Tang Fei also had this intention.

So everyone advanced to the driver's cab of the EMU and visited the driver's cab with great interest. Standing in the driver's cab, you can not only feel the breath of modern technology, but also see the situation in front of the front of the car through the large glass in front of the driver's cab, and the vision is very broad.

The driver's cab of an EMU is completely different from the driver's cab of an ordinary electric locomotive, and the two are very different.

Because in the process of EMU operation, the driver's responsibilities and roles are completely different from those of ordinary electric locomotives, and the operation of EMUs no longer mainly depends on the operation of the driver, but through various signals of the operation control system, through which the rapid operation of the EMU is controlled.

After checking in the driver's cab, everyone entered each carriage and began to check the situation in the carriage one by one. It can be seen that the assembly of the EMU is really basically completed, and there is no need to continue the assembly in the carriage. The seats are neat and beautiful, and the floor leather is well designed.

The carriage gives people a warm and comfortable, but also a sense of modern atmosphere, which is the perfect combination of modern technology and arts and crafts design, and is completely in line with people's aesthetic views.

Whether you look at it from the outside or visit it inside, you will find that its appearance is simply outrageous, regardless of the performance, at least it looks very high-end and atmospheric.

Of course, its comprehensive performance, safety performance, etc. are the most advanced in the world, and this is the most outstanding EMU in the world's 200-kilometer class EMU.

Tang Fei stayed in the assembly workshop of the Hongxing Factory for a long time, mainly visited the situation of this EMU, and was extremely satisfied and full of expectations for its off-board.

In the afternoon, Tang Fei mainly stayed in his own office of Jiuzhou Industrial Group.

Brewing a cup of hot tea, sitting on the comfortable and wide boss's chair, I thought to myself, it is estimated that in a few days, the first EMU will be fully assembled, and after testing, it will be about ten days before the train can be disembarked.

Get off the bus!

What a thing to look forward to!

was thinking about getting out of the car, Tang Fei's mobile phone rang, this was Zhang Ping calling from the capital.

As soon as the phone rang, Zhang Ping said with great joy: "Mr. Tang, I want to tell you a good news, the drone military project has been officially completed!"

Although he had already known about this matter in the morning, when he heard the news again, Tang Fei still felt an inexplicable joy in his heart.

Tang Fei said: "Director Zhang, this is really good news, the UAV military project has been approved, which means that it is a project belonging to the military, and it also provides strong support for the future production and manufacturing of UAVs." ”

Zhang Ping said: "The UAV project, the future of the production and manufacturing is of great help, I will come to Qingjiang City in a few days, for you to send a copy of the military project, in addition to looking for you to understand the construction progress of the UAV Dongguan City Manufacturing Factory and the finishing of the UAV body and engine technical data." ”

Zhang Ping simply came to Qingjiang City directly, ready to chat with Tang Fei in person, and by the way, he also brought a copy of the drone military project approval document to Tang Fei, as for the original copy of the military project approval, it was left in the military.

Tang Feidao welcomed: "Director Zhang, welcome to Jiuzhou Industrial Group again, when will you come and tell me, so that people and cars can be arranged to pick you up at the airport." ”

Zhang Ping said happily: "Yes, when I book a ticket, I will call you again, and when I arrive in Qingjiang City, we have to have a good chat and talk." ”

Tang Fei said: "No problem, we can even go to Dongguan City together." ”

……

A domestic aero engine manufacturing plant.

Yi Chunhua is organizing a meeting on the technical seminar on a new turbofan engine that they have undertaken to develop, which is in the process of trial production, but there are many problems.

Now the discussion is about the technical problems of turbine blades, they refer to the turbine blade design technology of foreign advanced engines, the turbine blades of this engine also use hollow turbine blades, each blade is not only hollow, but also has a lot of tiny pores, so that when the turbine blades are working, a layer of air film is formed on the surface of the blade through these pores, which plays a protective role in the blade.

For aero engines, the pre-turbine temperature is an important technical indicator, and the higher the pre-turbine temperature, the more advanced the aero engine, the better the comprehensive performance, and the larger the thrust-to-weight ratio of the engine.

However, the temperature before the turbine is too high, which is a great test for the turbine blades, at such high temperatures, the turbine blades must not only maintain sufficient hardness and strength, but also output huge power, which needs to be fully considered in the design.

The design of turbine blades is often one of the key design technologies of turbofan engines, and Yi Chunhua has obviously not fully mastered the design of the world's advanced turbine blades, and is only based on the blades of foreign advanced engines for reference, lacking sufficient technical information.

That is to say, they draw scoops according to the gourd, and the bad thing to say is that they have copied the turbine blades of advanced foreign engines, and have not mastered the essence of the design, which is not, the problem will come out.

The turbine blades they designed and manufactured have a very short life during the test process, often after a few hours of commissioning, the blades will appear micro-cracks, and the blades can only be scrapped.

When there is such a problem, Yi Chunhua's hair seems to be a lot grayer, similar to the meeting just now, they have held several times, but they still haven't come up with an effective solution.

What should I do?

……..

Today's three watches, the second one is sent!
