Siheyuan: After being robbed of marriage, the traveling frog returns

Hearing Chen Fen's explanation, Liu Weiguo was skeptical, "You...do you really have blueprints?"

"If Uncle Liu doesn't believe it, you can visit our factory now."

"Come on, let's go to your factory now and chat while walking."

It was too late for dinner, so Liu Weiguo took Chen Fen to the Red Star Rolling Mill in a jeep.

On the way, Liu Weiguo looked solemn.

First, they were worried that Chen Fen and the others would cause trouble, and it would be easy to go to jail.

Secondly, I am also a little excited, if what Chen Fen said is true.

Then Huaxia will be able to independently develop its own third-generation aircraft, which is the most advanced third-generation aircraft.

It can raise China's air combat capability and air defense capability to the same level as the Soviet Union and the United States.

With hesitation and excitement, the two finally arrived at the Red Star Steel Rolling Plant.

It was already late at night, and the Red Star Rolling Mill looked the same as usual.

But such an ordinary rolling mill is actually producing the most advanced third-generation rolling mill in the world.

No one would think of who it would be.

When Liu Weiguo and Chen Fen entered the factory area, they found that many workers were still working overtime.

"Now our factory has started to work in three shifts. Each shift works for eight hours, and the machines are shut down 24 hours a day."

Listening to Chen Fen's explanation, Liu Weiguo nodded, "Take me to see the blueprint."

"Uncle Liu, follow me this way."

Chen Fen took Liu Weiguo to his office, and then took out a stack of drawings from a safe and handed them to Liu Weiguo.

Liu Weiguo glanced at it, but of course he couldn't understand it.

However, he could still recognize the graphic of an airplane above.

"This is the blueprint of the third-generation machine you mentioned?"

"Yes." Chen Fen nodded, "The stack below is the blueprint of the F100-PW-100 engine, which is matched with the third-generation engine."

"How did you get these blueprints?"

Chen Fen knew he was going to ask this question, "I got these blueprints from abroad. I have a foreign friend. He...he is...uh...he is the research and development personnel of the third-generation aircraft..."

The reason sounds far-fetched, but such a complete set of information and drawings.

It's hard to believe that Chen Fen did it himself.

Of course Liu Weiguo would not believe this reason, because Chen Fen didn't have any foreign friends at all.

However, the blueprints and the complete set of materials are all here, and it is not easy for him to delve into them.

After all, everyone has their own secrets, so it's fine if Chen Fen doesn't want to tell them.

After asking about the source of the blueprint, Liu Weiguo's face became solemn again, "Are you confident in producing this third-generation machine? You must know that if our country has the production capacity of this third-generation machine, then we will no longer be held back by the West or even the Soviet Union. !"

Now that Huaxia is restrained by Su and the West, it can be said that it is in a dilemma.

It is also difficult to live in the middle of both sides.

It is true only if you have the strength, so Huaxia will make up its mind to engage in nuclear weapons.

With this third-generation machine, China will have more voice in the world!
Facing Liu Weiguo's ardent expectation, Chen Fen nodded, "I have [-]% confidence that it can be done, but this matter must be kept secret, we need to do it in secret."

"No problem, as long as you can figure it out, I will keep it secret for you, and even provide you with all kinds of equipment you need."

"That couldn't be better."

With Liu Weiguo's support, Chen Fen has more confidence in building the third-generation machine.

However, Liu Weiguo also has conditions. "If the third-generation aircraft is really produced, then I will propose that the country convert the Red Star Steel Rolling Plant into a military aircraft factory, but the drawings of the third-generation aircraft will be submitted to the country for national research."

"No problem, I originally wanted to hand it over to the country."

"Okay!" Liu Weiguo patted Chen Fen on the shoulder, "Your family and country are righteous, you don't have to worry about the third-generation aircraft, I will help you with anything!"

"Thank you Uncle Liu!"

Liu Weiguo laughed a few times, he was really happy from the bottom of his heart.

It's not that I'm happy that I can devote myself to the development of the third-generation machine, and how much credit I can get afterwards.

But I am glad that China's national defense strength has increased a lot.

I am glad that Huaxia has mastered this cutting-edge technology, so that Huaxia will no longer be bullied.

That's why he supported Chen Fen so firmly.

And Chen Fen was also very excited, with the support of someone like Liu Weiguo.

The third-generation aircraft, which was originally planned to take a year or two to test flight, may be available this year.

He also looks forward to seeing what kind of shock the world will have when the third-generation aircraft takes off.

No one knows what kind of changes this third-generation aircraft will bring to Huaxia.

……

On this day, Chen Fen was studying the blueprints in his office.

Lao Zhang, a fitter in the factory, suddenly found him.

"Chen Gong, come and take a look, there is a problem with a screw."

"Screw?" Chen Fen was a little puzzled, "What can go wrong with a screw?"

"According to the drawing you gave, the screw should have a thread length of two millimeters and a length of five centimeters, but to make a screw five centimeters long, the thread length must be about three millimeters."

Chen Fen quickly understood what he meant, that is, the technology for grinding threads is not yet mature.

The screws of later generations are generally produced by professional abrasive tools, and the production of such screws is not a problem at all.

However, with the current technology, it is difficult to produce such screws.

After hearing this, Chen Fen stood up and followed Lao Zhang to the workshop.

At this time, a large group of people are gathering together, studying a small screw.

Seeing Chen Fen coming, he didn't have time to say hello to him.

Pull him directly and start studying together.

"Mr. Chen!" Lao Zhang showed embarrassment, "As you can see, it is still very difficult to make this kind of screw with our current technology."

Such a large project of the aircraft is going to be carried out, how can it be difficult to be stumped on a screw?
Chen Fen squatted down, picked up a semi-finished screw and looked at it carefully.

Soon, he discovered the problem.

It is not that the technology is not up to standard, but that there is a problem with the process.

Chen Fen showed the semi-finished screw in front of everyone, "When you made the screw, how many times did you spin it?"

The so-called threading is a process in the manufacture of screws.

The finished product made by heating and rolling the steel billet is cold drawn to the required wire diameter.

It is a key step in manufacturing screws.

"One more time!" Lao Zhang was a little puzzled, "It's always been done like this before!"

"Try to draw silk several times before the temperature drops, and then see?"

When Chen Fen gave a suggestion, everyone was skeptical.

But having a way is better than nothing.

Everyone is also ready to try it to see if it is true what Chen Fen said.

By changing the production process, qualified screws can be produced!
