The on-site commander was a bespectacled engineer, and although he didn't throw his helmet into the air like the technicians, he was so excited that his face was red and he couldn't speak very well.

"Academician Sima, I'...... We really ...... Success!" In the corner of his eye, two crystal tears were flashing, "More than 20 years, I have been involved in locomotive design for more than 20 years, and there has never been a moment when I was so excited!"

When it came to the depths of love, he was almost choked.

Sima Lili was as calm as ever, pointed at Lin Feng and said, "Uncle Ma, you should thank him." ”

"Yes, yes! Look at my brain, confused!"

Lin Feng was held tightly by the horse worker, and after saying some words of thanks, he waved his hand again, and twenty or thirty people rushed over, lifting Lin Feng up and throwing it into the sky like a leather ball.

I'll go, Lin Feng really doesn't know what to say, what kind of era is this way of celebrating!

But he can really understand their feelings, so let them throw them around.

After a while, Test 1 slowly returned, and everyone lubricated it like their own children, and even wiped the dust with rags that weren't there.

"To continue digging tunnels, the main plant must reach 500 kilometers. "Then the counterweight is simulated and driven at a speed of more than 2,500 kilometers for 100 hours without any failure before it can be put into operation." Uncle Ma, the maintenance of the train, the inspection plan and the formulation of the rules will be hard for you. ”

"Don't worry, I'll do it all. Ma Gong said confidently, "Not only the test train, the construction of temporary stations in Rongcheng and Fucheng, but we also have to complete it within 10 days, and strive to carry out the first trial run on New Year's Day!"

These things do not belong to the R&D unit, and Sima Lili's next work is to design the shell, doors and windows, seats and various safety facilities for the train.

This is all trivial things, but the pain is that things are complicated, and there are many things that need Lin Feng's assistance, and the two of them made and guided the installation while designing the drawings, and it took a week to make an 8-car super train look a little bit better.

If you want to achieve the most comfortable, more design and effort will be needed, and the minutiae will naturally be picked up and filled.

When all the work was completed, Lin Feng and Sima Lili took a thick stack of materials, and the two began to work on the small table in the workshop to carry out the most comfortable work of Lin Feng in the past month or so, settling accounts.

There is a song that goes like this: In the dead of night, it is time to count money. Don't talk when you count money, don't talk!

Starting from the engine, an 8-car super train needs two engines, one in front and one behind, otherwise it will be pushed and walked when driving in the opposite direction, which is very unsafe, which is 3 billion.

510 kilometers of tunnels were excavated, 13 million per kilometer, and the total price was 6.63 billion.

510 kilometers of track, with an average weight of 102 kg per kilometer, and a total price of 15.606 billion.

Finally, the main frame of the train, wheels and other important accessories, a single carriage consumes 330 kg of supramolecular aggregate materials, and the total price of 8 carriages is 792 million.

A total of 26.028 billion.

Among them, the cost of the track is 22.236 billion, with an average of only 43.6 million per kilometer, and the maximum lighting facilities will be added in the later stage, and the total price will not exceed 50 million per kilometer, which is much cheaper than the normal subway track, and even cheaper than some ground rails.

A total of 3.792 billion was spent on 8 carriages, which is indeed sky-high compared to ordinary trains.

Lin Feng and Sima Lili discussed this problem, if the two 6,000 kilowatt engines are replaced by four 1,500 kilowatt engines, which are installed and matched like the current EMUs, they can fully achieve the expected results.

In addition, the train frame does not require as many supramolecular polymeric materials, so the total cost can be reduced by more than half when mass production.

This is the difference between laboratory research and development and mass production, one is to seek results regardless of cost, and the other is to be careful and pursue the lowest cost.

So about 1.9 billion trains, and it also includes two to three years of electricity, which is tens of millions of expenses saved.

Such a train should be acceptable to the country.

In the end, Lin Feng earned almost 25.5 billion in his pocket, plus his appearance fee of 2 billion, 27.5 billion was in hand.

After the accounts were settled, Sima Lili sorted out all the information and reported it to the Academy of Sciences together, and the matter was over.

Lin Feng also soon received a text message prompting that the 275 cash had arrived.

............

The two of them walked on the open grass of the station, basking in the warm winter sun, Sima Lili narrowed her eyes slightly, and let the sunlight fall on her face.

"I thought it was going to be the New Year, but it was completed ahead of schedule. She habitually put one hand in a deep pocket and one hand in a thick folder.

"Aren't you going to be able to enjoy a long vacation?"

"For us, there are no holidays at all. Sima Lili said, "The end of one work means the beginning of the next work." ”

It's really hard, Lin Feng said in his heart. He doesn't quite understand this way of life, if every minute and second is forgetting to work, where will he enjoy life when he comes, and where will he have the time to fall in love?

Sima Lili seemed reluctant to talk about personal life, and soon shifted the topic to work.

"I received a call from the Academy of Sciences today, asking me to discuss something with you. ”

Lin Feng's heart jumped, knowing that what he was supposed to come was still coming after all.

You don't have to say it to guess what she's trying to say. For such super-engines and batteries, to say that the state does not intend to apply them to the military sphere, then no one will believe it.

It was only a matter of time before supramolecular materials were combined with such engines to create powerful fighting machines.

Sure enough, Sima Lili continued: "We want to buy some more engines of various powers, not for the manufacture of trains, but for other places, I hope you can agree." ”

"Like planes, warships or submarines?" Lin Feng said with a smile, "Actually, why ask me this question, since I took out the engine and sold it, I already expected this result." ”

"You may not understand that making these things is hundreds or thousands of times more complicated than building a train. The number of parts needed is unimaginable. We don't just need your engine and battery, we need your help machining parts. ”

Lin Feng thought about it and felt that there was nothing wrong with it.

Anyway, the current special processing equipment, the maximum production size can only reach 3 meters, shipbuilding is impossible, and building an airplane can be so-so.

In Sima Lili's words, building an airplane is not a simple matter, even if there are engines, materials, and processing equipment, it is not enough, and design concepts are also needed, and it is estimated that it is impossible to complete it in a year and a half.

"I'll give you permission, you can get it yourself," Lin Feng said with a smile, "Anyway, how many materials used will be automatically counted, and then we will check out according to the data on the machine." ”

"Thank you. ”

Lin Feng waved his hand: "Do business, it's too much to say thank you." ”

Under the strict protection of more than a dozen people from Jia Xiaoliang, Lin Feng finally left the station, and he felt that he didn't want to return here for at least a month.

Driving on the bustling street, the shops all over the street are dressed up in joy, looking at the flashing Christmas trees and white-bearded old men, he suddenly remembered that Christmas is here again. 2
