Tang Fei returned to Deep Sea City.

To be honest, when Zhang Ping told Tang Fei that the United States had obtained the introduction of the drone, Tang Fei was a little worried at first, but now he is no longer worried.

The development of the UAV is progressing smoothly, and in a few months, the UAV manufacturing plant will be preliminarily completed, and most of the parts will be trial-produced, and the general assembly of the first UAV can begin at that time.

In addition, the imported parts of several drones in the early stage are all complete, so you don't have to worry about being stuck by the Americans. If the Americans really obstruct the production and manufacturing of their drones in every possible way, such as starting with imported spare parts or imported materials needed for drones, then they will use the "god-level industrial master" system to exchange these things, or simply develop them by the system, and be manufactured by Jiuzhou Industrial Group or handed over to relevant domestic manufacturers for manufacturing.

I didn't have any worries in my heart, and I felt a lot more relaxed.

Tang Fei happily returned to Shenhai City, as for Ding Liang and others, they stayed in the capital for the time being, and began to start the first round of contact with the relevant departments to discuss the EMU order in detail.

The general framework has been negotiated by Tang Fei and Yan Shihua, as long as some details are discussed in detail within this framework, it should not be a big problem.

Tang Fei also fully believed in Ding Liang and handed over everything to them for the rest of the matter, Tang Fei just had to wait for the good news in Shenhai City.

Soon after coming back, Tang Fei received a call from Xie Zhenhua.

Obviously, Xie Zhenhua has been paying close attention to the progress of the situation, and he very much wants to know the specific situation of the matter, so he specially called Tang Fei to inquire.

"Brother, I heard that you have returned from the capital. ”

After receiving Xie Zhenhua's call, Tang Fei knew very well what Xie Zhenhua wanted to ask, and said without concealment: "Yes, I came back from the capital yesterday, Lao Xie, you want to ask about the EMU order." ”

Xie Zhenhua said: "Yes, yes, that's it." ”

He kept saying "yes, yes" and the like, and he wanted to know the details of the matter very much. Not only him, it is estimated that many people in the Red Star Factory want to know the specific situation of this matter.

National procurement of EMUs.

As we all know, the price of a train is not cheap, basically more than 100 million yuan, if it is a 10-car train, 12-car train and the like, such a train EMU will be worth 100 million tens of millions.

If you add a few sleeper cars, the value is even higher, probably close to 200 million. A lot of people think that this should be a big deal.

Xie Zhenhua was very concerned about this matter, and called with hope to ask, with a strong expectation in his tone.

Tang Fei seemed to be able to feel Xie Zhenhua's mood, and said loudly: "Old Xie, you can be happy and happy, Minister Yan and I have negotiated the general framework, and the state will purchase a total of 32 JF200A EMUs from Jiufang EMU, and the total contract value is estimated to be about 5 or 6 billion." ”

OMG!

Xie Zhenhua almost shouted in surprise, he originally thought that it was just a trial purchase of 10 trains and 8 EMUs, but he didn't think that there would be as many as 32 trains.

The total value of the contract is five or six billion!

Xie Zhenhua was completely excited, "Brother, this is really great news, I will hold a special office meeting in a moment to tell you the good news." ”

Tang Fei smiled happily, "Lao Xie, this is just the beginning, the first batch of EMUs purchased by the state, part of which is used for the operation of the newly built Xin'an Express Railway Line, and part of it is used for the passenger operation of the north-south railway artery from Beijing to Changzhou City." ”

It's just the first batch.

That is to say, after the procurement of this batch of EMUs is completed, the state will purchase it according to the actual situation, and the total number of future purchases can be hundreds or even hundreds of columns.

Xie Zhenhua was even more excited.

Tang Fei continued: "Minister Yan also revealed that the country needs 160-kilometer EMUs, mainly for the operation of ordinary railway trunk lines, in addition, the first high-speed railway will start construction immediately, and a large number of 300-kilometer EMUs will be needed in the future. ”

Xie Zhenhua was pleasantly surprised: "Doesn't this mean that the future market for EMUs is very huge." ”

"Of course. Tang Fei affirmed: "We are a large country with a population of more than one billion, a vast territory, and a large number of EMUs are needed, in fact, our Jiuzhou Industrial Group has already started the development of 160 km grade EMUs, and soon after, we will start the trial production of this grade EMUs." ”

What the!

Xie Zhenhua reacted and said loudly: "Brother, the surprise you gave me is one after another, even the 160-kilometer EMU you have already started to develop, it's amazing!"

The two chatted on the phone for at least ten minutes, and finally Xie Zhenhua ended the call unsatisfied, without thinking, he would immediately hold an office meeting of the Red Star Factory to share this series of good news with everyone.

After answering the call, Tang Fei sat on his boss's chair with a smile on his face, thought about it and said, yes, first develop the 160-kilometer EMU through the system.

Just do it.

Tang Fei first took out a pen and paper, and wrote down the relevant parameters and technical requirements of the 160-kilometer EMU with the memory in his mind, and he could use it later.

After writing these things and roughly checking them to be correct, Tang Fei opened his "god-level industrial master" system, entered the R&D interface, and prepared to develop this EMU through the system.

As a reborn person, Tang Fei is clear about the future development of Huaxia's EMU technology, and also clearly knows that several star models at the world's leading level in the future, including 160 kilometers of power centralized EMUs.

This time, Tang Fei is ready to refer to this car and let the system be developed.

According to the distribution of power, there are power dispersed type and power centralized type, each with its own technical advantages, JF200A type EMU is the power dispersion type.

Power dispersion means that the power unit is dispersed and installed in several compartments, controlled by the driver through the computer in the cab. Advantages: the power dispersed installation train starts quickly, the ramp starts easier; disadvantages: the power unit is scattered in each carriage, easy to fail, and once the fault occurs, the maintenance cost is also increased accordingly.

Centralized power means that the power unit is centrally installed at both ends of the train. Advantages: the power unit is concentrated, easy to overhaul when the fault occurs; Disadvantages: due to the centralized installation of the power unit, the power unit has poor control ability over the whole vehicle, and there will be slow start and ramp start difficulty.

Because each has its own advantages and technical advantages, in the world, there are both centralized EMUs and decentralized EMUs.

The 160-kilometer EMU designed and developed this time is a power centralized type, and it is also a short-marshalled EMU, generally 6-car or 8-car train, up to 10-car train.

The advantages of such short marshalling EMUs using power concentration technology are more obvious.

Tang Fei began to input a series of parameters and technical requirements on the R&D interface of the system, and after the input was completed, he checked and found nothing wrong, and Tang Fei started the R&D function of the system.

Consumes a total of 1000 gold.

In just about 1 minute, the development is complete, and the system generates a large volume of documents. Tang Fei skillfully copied the newly generated file package into his computer.

Then, Tang Fei sat in front of his computer and wanted to take a look at the research and development results of the system and see how the things produced by the system were.

It's still the old rule, let's look at the introduction of this EMU first.

After just reading a few pages, Tang Fei's face showed a look of surprise, worthy of the system, the iron law of "produced by the system must be a high-quality product" is vividly reflected this time.

Tang Fei has a very good understanding of the 160-kilometer power centralized EMU developed by Huaxia Future, and his memory of many technical parameters is very clear.

This development is almost a copy of that EMU, but because it is handed over to the system for research and development, the EMU successfully developed by the system is obviously better than that EMU.

On the basis of that EMU, not only the interior decoration, plane layout, and sealing performance of the EMU have been greatly improved and optimized, but its biggest technical highlight is the optimization of the control bus.

With this improved and optimized control bus, the EMU can meet the functions of control and reconnection at both ends, and even the opening and closing of the doors are controlled by the driver's cab.

Although this is a short-train EMU, because it has the function of interconnection and mutual control, two short-train EMUs can be connected together to form a long-train EMU.

For example, two 8-car EMUs are connected together, and a 16-car EMU can be formed, which can greatly improve the passenger carrying capacity during the peak period of passenger flow, such as during the Spring Festival.

The successful development of JF160A power centralized EMU will increase the demand for passenger transport in Huaxia and meet the needs of electrified general-speed railways with a wider area and longer line length in Huaxia and some high-speed railways with a design speed of 200km/h, and the future market prospects are huge.

Tang Fei carefully read the introduction of the 160-kilometer power centralized EMU, and was very satisfied, and has positioned the JF160A EMU.

The market space for such EMUs is very huge, which can not only run on ordinary railways, carry passengers like ordinary passenger cars with the prefix "K" and "T", but also meet the needs of intercity railways.

There is no intercity railway yet, but in a few years, some large urban agglomerations in China will build intercity railways, and a one-hour or two-hour traffic circle will be built, and a lot of such EMUs will be needed.

After reading this introduction information, Tang Fei roughly looked at the design and process technical data of the JF160A EMU, and then copied them into a large-capacity USB flash drive, preparing to hand over this USB flash drive to Ding Liang after he returned from the capital.

The research and development of the 160-kilometer EMU has been completed, should the 300-kilometer EMU be done now?

Tang Fei thought so in his heart.

……

Today's three watches, the second one will be sent.
