Zhang Ping's phone.

Tang Fei frowned slightly, and thought in his heart, Zhang Ping took the initiative to call himself two days ago and expressed a happy New Year to himself, and that day happened to be the first day of work after the holiday of Jiuzhou Industrial Group.

Zhang Ping called himself only two days later, there must be something.

So, Tang Fei immediately answered the call. As soon as the phone rang, Zhang Ping's eager voice came from inside, "Mr. Tang, I'm sorry, we have encountered some problems in the trial production of drones." ”

"Oh. Tang Fei listened carefully.

Zhang Ping didn't elaborate, maybe he couldn't say a word on the phone, he just said that the UAV engine encountered processing problems in the process of trial production, and the processing accuracy of some key important parts could not be reached.

He did not elaborate on which parts could not meet the accuracy requirements and what reasons could not meet the accuracy requirements. After briefly saying that the accuracy could not meet the requirements, he also said that he would take the time to come to Shenhai City in the next two days.

The whole set of UAV technology comes from Jiuzhou Industrial Group, which is currently facing the problem of processing accuracy, so he can only go to Tang Fei to seek solutions, such as whether the design requirements can be reduced, or whether the design scheme can be changed, etc.

After answering this call, Tang Fei also thought about it a little.

To be honest, after receiving this call and hearing Zhang Ping say such a situation, Tang Fei felt quite surprised. Originally, I thought that I had provided a complete set of detailed technical information, and the domestic aero engine factory should be able to produce the engine of the UAV relatively smoothly for itself.

Where do you think, there is such a problem.

In fact, Tang Fei overestimated the level of the domestic aviation industry a little. Due to the technological blockade of Western countries and the embargo of advanced processing equipment, there is still a big gap between the level of the domestic aviation industry and that of developed countries. In particular, there is a gap in materials and processing strength.

Whether it is processing strength or material, they are two important factors that affect the level of aero engines. These two aspects are shortcomings, which have lowered the level of the domestic aviation industry as a whole.

This is not to blame Tang Fei, it can only be said that Tang Fei is too confident in the whole set of technical data produced by the system, and ignores the current situation of the domestic aviation industry.

In addition, this is the pinnacle of small and medium-sized turbofan engines, the requirements are very high, whether it is the requirements of materials, or the requirements of processing accuracy, limited by processing equipment, the domestic aero engine enterprises in the trial production process encountered such a problem, normal.

Seeing that Tang Fei was silent for a long time after answering the call, Li Xueyan next to him couldn't help but ask with concern: "Brother Fei, what's wrong?"

Tang Fei came back from his contemplation and said with a smile: "It's okay, it's just a trivial matter, let's go, let's get out of the car." ”

Tang Fei usually doesn't take things home at work, so that these things affect the mood of his family. Like the difficulties encountered in the trial production of drone engines, of course he will not tell Li Xueyan.

Under the leadership of Tang Fei, the three of them got off the train and walked towards Changzhou North Railway Station. Xu Guangming still followed behind quietly, keeping a suitable distance, trying not to affect Tang Fei and Li Xueyan.

Holding his wife's soft and smooth little hand, he walked into Changzhou North Railway Station, and under the arrangement of the station, Tang flew to the platform where the EMU was about to stop.

When they entered the station just now, there were already people waiting for Tang Fei at the station, because they had already been notified that the boss of Jiuzhou Industrial Group would come over in person.

The train arrived on time at 9:52 a.m.

Tang Fei raised his hand and looked at the watch on his wrist, thinking in his heart, this EMU will come over in ten minutes. While waiting for the EMU to come, Tang Fei chatted with his wife while looking at the huge Changzhou North Railway Station.

It is worthy of being a well-known railway station in the country, much more than Qingjiang Railway Station, there are many more people, there are people everywhere, and a lot of trains are stopped, many people are getting on the train, and many people are getting off.

Many of these trains are Shaoshan electric locomotives, and some are DJ4 electric locomotives. Tang Fei knew that with the mass production and manufacturing of DJ4 electric locomotives year by year, Shaoshan electric locomotives would be gradually replaced, and then gradually withdraw from the stage of history.

It's only ten minutes, and the time passes quickly.

Tang Fei looked at the time again and reminded, "Xue Yan, the EMU is coming over soon." ”

Hearing this, Li Xueyan showed strong interest, stretched out her neck and looked around, "Brother Fei, I'm really a little excited, it's the first time I've seen our EMU at the train station." ”

When I was working in the Mars Factory, this EMU was assembled in the assembly workshop of the Hongxing Factory, and Li Xueyan went to see it several times, but it was the first time to see the moving EMU at the railway station.

"It's coming, it's coming!"

Tang Fei's eyes were sharp, and he had already seen the figure of this EMU on the railroad tracks in the distance, slowing down and driving towards here.

"It's really coming!"

Li Xueyan also saw it, and suddenly, she almost cheered, and the joy was almost completely written on her face.

The EMU came, began to enter the Changzhou North Railway Station, and drove towards the platform where Tang Fei was standing, and with its arrival, it soon attracted the attention of many people.

There are so many people here that the EMU has not yet fully entered the station, and some people exclaimed, apparently it was the first time they had seen the JF200A EMU.

"Look, what kind of train is that, it's so beautiful!"

"Really, it's completely different from ordinary trains, and the front of the locomotive is in the shape of a bullet, which is so beautiful. ”

“.…..”

As this EMU pit stops, more and more people notice it. Many people's eyes were attracted to it, and it became the focus of Choshu Railway Station in an instant.

There was even a passenger who was carrying a suitcase and was getting on the train, because he was looking at the EMU in the distance, he accidentally hit the door, causing some passengers around him to laugh good-naturedly.

He himself was not angry, and after laughing, he got on the train again and looked sideways at the EMU. Even after getting on the train, when I entered the train car, I saw the EMU from a distance through the window glass.

The EMU is here and has become the focus of attention.

A lot of people were watching, many people were talking about it, and some people even picked up the camera they carried with them and took a few photos.

"Brother Fei, let's get in the car now. ”

Seeing that the EMU was stopped on the railroad track next to the platform, it was in front of him, and Li Xueyan made such a request with great interest. Tang Fei waved his hand and said, "Let's go, let's get in the car." ”

The EMU arrived, stopped at Changzhou North Railway Station, the doors of two carriages were opened, and some people came down from above, they belonged to the accompanying personnel, and the whole train basically did not have any passengers except for these accompanying personnel, because the EMU had not yet been put into formal operation, and it was only a trial operation stage.

Tang Fei took Li Xueyan to board this EMU and visited the train.

As soon as she came in, Li Xueyan's eyes lit up obviously, and she was amazed by the beauty of the internal design of this EMU, and also admired its cleanliness and tidiness.

"Phineas, it's pretty good. ”

Tang Fei nodded, and took his wife to visit this EMU, and also introduced this EMU to his wife.

Like a few treasures, Tang Fei gushed endlessly, introduced in detail, and a lot of data was also very accurate. Tang Fei didn't know how many times he had read the introduction information of the JF200A EMU, and he remembered a lot of data very clearly.

After listening to Tang Fei's introduction, coupled with the visit of one carriage after another, Li Xueyan's eyes showed admiration, and she almost gave a thumbs up and said, Brother Fei, you are really amazing, you have made such an advanced and excellent bullet train.

In addition to taking his wife to visit the train, Tang Fei also asked the competent technicians of the car to learn about the recent trial operation of the EMU.

Tang Fei was very satisfied with the fact that there were zero failures in the operation of the EMU and that it reflected a very high safety performance.

Tang Fei also learned from the technician in charge that the EMU had set a new record for itself, and on the way to Changzhou North Railway Station, its maximum operating speed reached 300 kilometers.

This is a 200-kilometer EMU, and it is not on a high-speed rail track, it can reach a speed of 300 kilometers per hour, which is really remarkable, much faster than ordinary trains, it is simply a lightning speed.

Tang Fei remembered that in the future, there was a 350-kilometer EMU that ran at a speed of more than 600 kilometers per hour, which was really the speed of an airplane.

At Changzhou North Railway Station, Tang Fei stayed for a long time and knew that he would leave at noon, not only visited the EMU very well, but also learned a lot about the EMU in the trial operation process, the high safety and comfort of the EMU, which made Tang Fei very satisfied.

……

Zhang Ping arrived in Shenhai City.

He took the initiative to call Tang Fei yesterday, saying that he would take the time to come to Shenhai City in the past two days to talk to Tang Fei in detail about some difficulties encountered in the trial production process of the drone.

Tang Fei enthusiastically sent people and cars to the airport to greet him, and now, Zhang Ping has entered Tang Fei's office, and the two are sitting on the sofa talking, and there is still freshly brewed hot tea on the coffee table next to the sofa.

When he came in just now, Zhang Ping praised Tang Fei's big office, and then not long after, he got back to business and began to talk about the problems encountered in the trial production of UAVs, especially the trial production of aero engines.

However, before Zhang Ping had time to elaborate, a phone call interrupted his words, he picked up his mobile phone and answered the call, Tang Fei noticed, Zhang Ping's face gradually changed, and showed an angry look.

……

Today's third watch, the third watch is sent, thank you for your support, good night!
