Tang Fei was a little surprised, the system actually released a new task without warning.

What kind of mission will it be this time?

With a hint of curiosity in his heart, Tang Fei quickly opened his "God-level Industrial Master" system and quickly glanced at the taskbar of the system.

There is indeed a new task, which reads: "Dear host, please help in the development of the Harmony Electric Locomotive of the Red Star Plant, and help them solve the three main technical problems they are facing within three ......"

Mission Level: Grade C.

Reward: 7,500 gold.

Task failure penalty: Permanently disables the system upgrade function.

…….

Tang Fei quickly finished reading this new task, and thought to himself, there is a reason why the system has set the difficulty level of the task at C level, because it is clearly stipulated that the functions of the system cannot be used, especially the research and development function of the system cannot be used for research and development on behalf of the Red Star Factory, and the time limit is 3 months.

No wonder it's a C-level mission!

It's a lot of fun.

In order not to attract Xie Zhenhua's attention, Tang Fei didn't delay much, and after quickly reading this new task, he understood what was going on, and at the same time, there was a certain amount of pressure.

Not being able to use the functions of the system doesn't mean going into battle shirtless. Tang Fei thought in his heart, but for the time being, he didn't know what three main technical problems the Red Star Factory was facing, and he hoped that it would not be too difficult and within the scope of his ability to solve.

Seeing Xie Zhenhua looking at himself hopefully, waiting for his answer. Tang Fei pondered for a moment, and then said with a straight face: "Old Xie, don't worry, as long as I can help, I will definitely go all out." ”

Hearing this, Xie Zhenhua's heart was light, and he suddenly saw hope.

He thought in his heart, since Mr. Tang had already agreed, these technical problems would definitely be solved one after another.

He has confidence in Tang Fei and even more confidence in the technical strength of Jiuzhou Industrial Group.

Tang Fei agreed to help, mainly for two reasons. One is that the task of the system is there and must be done. Otherwise, the system permanently turns off the upgrade function, which is not a joke.

Second, he has an excellent relationship with Xie Zhenhua, and if his friend is in trouble, he must help him.

"Lao Xie, can you tell me about those technical problems, let me have a bottom in my heart. ”

Xie Zhenhua nodded, "Then I'll talk about it briefly, and we'll continue to talk about it in detail tomorrow......

Now I can really only say it simply, because these technical problems involve a lot of technical data, technical parameters, etc., even if Tang Fei wants to solve them, he needs the Red Star Factory to provide these things.

Tang Fei listened carefully, at least he had a general understanding in his heart, so that he had a bottom in his heart.

As the system task was released, there are mainly three relatively large technical problems, namely braking system problems, pressure conversion problems, and cooling system problems.

Tang Fei said in his heart that in history, the harmonious electric locomotive did encounter these technical problems in the development process, and it was very coincidental that he participated in the optimization and improvement design of the harmonious electric locomotive control system, and he knew better.

For electric locomotives, the control system is very important. The Red Star Plant is currently developing a 9600K electric locomotive, with high power and high load, and train braking is a big problem, and it is definitely not possible to copy the braking system of the DJ4 electric locomotive.

It needs to be perfected and improved on the basis of the DJ4 electric locomotive control system, and the design needs to be improved, which brings great technical pressure to the Red Star Factory.

Tang Fei thought in his heart, maybe he could help them solve this problem, and he needed to go to see the design of the Red Star Factory tomorrow.

As for the other two technical issues, although I did not participate in the design back then, after the design was successful, I had studied in depth and was relatively familiar.

After thinking about it for a while, Tang Fei said, "Old Xie, we should be able to solve these problems. ”

Suddenly, Xie Zhenhua was extremely happy, there was no pressure in his heart, and he said with a relaxed face: "Mr. Tang, I knew that you would not let me down, I knew that you could do it." ”

Then, his conversation came up again, drinking and eating with Tang Fei, and at the same time continuing to chat with Tang Fei, the topic was mainly about the harmonious electric locomotive.

He told Tang Fei that the DJ4 electric locomotive will be renamed the Harmony electric locomotive in the future, and it will be a member of the Harmony series of electric locomotives, with the model "HXD1", that is, the Harmony 1 electric locomotive.

The harmonious electric locomotive being developed by the Red Star Factory is the "HXD1B" electric locomotive, which is designed and developed on the basis of the technology of the "HXD1" electric locomotive, and is still an eight-axle locomotive, with an output power of 1200K per axle, a total traction power of 9600K, and a maximum speed of 120 kilometers......

Maybe it was because the pressure in Xie Zhenhua's heart was gone, his interest was very high, and he and Tang Fei drank in Furong Building until late before going back.

That night, Tang Fei slept in his old house, which was still his familiar bedroom, and his parents came back a few days earlier, and they had already cleaned up the room, which was very warm.

Lying on the bed, smelling the fragrance of the quilt, it seems to be back to the time when I just graduated from college, at that time, I slept in this bed every night, and was busy with the affairs of Jiuzhou Industrial Co., Ltd. every day.

The next day.

Tang Fei was going to go to the Red Star Factory, which he had made with Xie Zhenhua last night.

Anyway, there are still two days before the first train of JF160A EMU is delivered, and there is no need to rush to Jiufang EMU, so go to Xie Zhenhua to sit there and have an in-depth understanding of the technical problems they encountered in the development of the "HXD1B" electric locomotive.

It was not far from his home to the Red Star Factory, and it took only ten minutes to walk, Tang Fei didn't even bring Xu Guangming, nor did he drive by himself, but walked to the gate of the Red Star Factory easily.

Looking at the gate of the Red Star Factory, that familiar feeling came to his heart, and Tang Fei felt as if he had returned to a few years ago.

couldn't help but shake his head gently, Tang Fei walked into the factory area of the Red Star Factory, came to the large office building of the Red Star Factory, and walked in.

"Mr. Tang, you're here!"

When Xie Zhenhua's secretary saw Tang Fei, he was immediately extremely enthusiastic, "Mr. Xie is in the office, already waiting for your arrival." ”

Probably hearing his secretary's voice, Xie Zhenhua immediately came out of the office and shook hands with Tang Fei happily, "Brother, you came over so early, hurry, please come inside." ”

He enthusiastically invited Tang Fei into his office, personally made hot tea for Tang Fei, and said hopefully: "Mr. Tang, since you agreed to help us solve the three main technical problems last night, I have slept peacefully for the first time. ”

Tang Fei smiled happily and waved his hand: "Lao Xie, I need to understand your specific design technical information first, well, let's start with the braking system." ”

All this has been prepared for a long time.

Xie Zhenhua immediately took out the design materials of the braking system, unfolded these technical drawings on his large desk, and began to introduce their entire design to Tang Fei in detail.

He used to be engaged in technology, and he also worked in the position of chief engineer of the Red Star Factory for many years, he is a technical expert in this field, and he is very expert in introducing it in detail and depth.

Tang Fei listened carefully and looked at these design drawings carefully.

The braking system design of the HXD1B electric locomotive is derived from the braking system of the HXD1 electric locomotive, but it has been improved and refined to make its performance more advanced, more reliable and longer service life.

But at present, there is trouble, there are great technical problems in the design, for the technicians of the Red Star Factory, the power of the HXD1B electric locomotive is too large, it can pull a mass of tens of thousands of tons, such a large traction capacity, to be safe and reliable braking is a big problem.

After carefully looking at the design of the Red Star Factory, Tang Fei knew that this was basically not much different from the design before his rebirth.

Once the Red Star Factory also encountered problems in the design of the braking system, after repeated verification, again and again tests, it took several years to design successfully, using a brand-new, very scientific and reasonable design, such a design has also applied for international patents, and later was widely used in almost all harmony series of electric locomotives.

Tang Fei just remembers this design vividly, because he worked in the Red Star Factory for 10 years before he was reborn, and happened to participate in the design of the HXD1 electric locomotive braking system.

After reading these drawings, Tang Fei took the pen and paper, combined with the memories in his mind, and began to draw design sketches on the white paper while talking about this unique design.

Xie Zhenhua is worthy of being engaged in technology, Tang Fei didn't make a lot of effort, just drew a sketch, and after talking about this design idea and principle, Xie Zhenhua suddenly opened up.

He said with admiration: "Oh, why didn't we think of this design, brother, you are amazing." ”

After understanding this design, there is no need for Tang Fei to continue to explain in depth and in detail, Xie Zhenhua fully knows how to organize their technicians to design this braking system next.

Then, Tang Fei combined the memory in his mind, took a blank piece of paper, and began to draw a sketch of the principle of the transformer system while explaining his design ideas to Xie Zhenhua.

That's what happened in the office.

One speaks seriously, the other listens carefully.

If there was a third person here, the whole jaw would definitely fall to the ground in surprise. One is the boss of Jiuzhou Industrial Group, the other is the leader of the Red Star Factory, and the two of them are actually like this.

At this moment, Xie Zhenhua is completely like a student who studies with an open mind.

He is also worthy of being a technical background, Tang Fei doesn't have to work hard, often as long as he draws a sketch, after a little talk, Xie Zhenhua will be broken at all.

Time also flew by in this atmosphere, and soon more than an hour passed, and Xie Zhenhua's desk already had several sketches drawn by Tang Fei himself.

Outside the office.

Xie Zhenhua's secretary looked at the time from time to time, his face showed an anxious look, and he was hesitating in his heart, whether to knock on the door and go in to remind Mr. Xie that in ten minutes it would be the office meeting of the Red Star Factory, and it was still an expanded office meeting, not only all the important middle-level officials who attended the meeting had arrived, but many high-level executives were already waiting for Xie Zhenhua to pass.

Do you want to knock on the door to warn you?

After hesitating for several minutes, Xie Zhenhua's secretary walked to the door of the office and raised his hand to knock on the door of the office.

……

Today's third watch, the third watch is sent, good night everyone!
