I tinkered with cars and built a super military industry

Although Mr. Jin looked puzzled.

But the X-ray gun in his hand was still slowly moving between every weld of the tank body.

The X time machine went back and forth more than ten times, and Mr. Jin finally stopped.

Experience told him that the tank body welded by Li Yifan was indeed fine.

But Mr. Jin still couldn't believe it and had been working on tanks for decades.

What are some common problems and vulnerabilities of tanks?

What size screws are in which corner above and what size wrench is needed?

Jin Lao knew it even with his eyes closed.

Especially the welding of tank bodies.

When welding a car body, we only need to check and repair the seams.

Two people. It's normal to take a week.

Li Yifan's welding has never been so smooth this time.

It's better to say it's exaggerated than smooth.

For decades, no one has been able to weld a tank body without checking and repairing the seams.

Including Mr. Jin's own master, everyone has to make checking and mending the seams a top priority.

But Li Yifan only welded once.

Not to mention checking for leaks and fixing them, there is not even the most basic inspection.

It's like taking a test paper and handing it in after you finish it.

Mr. Jin took dozens of X-rays of the tank and studied them on the spot.

Looking through them one by one, I was completely immersed in the X-rays.

Li Yifan saw that Mr. Jin was so serious and didn't bother him.

The engine on the gantry crane was no longer assembled into the tank engine room.

Li Yifan sat down on the spot, and he sat there until noon.

Mr. Jin happened to finish reading the X-ray films at this time.

After watching the X-ray, Mr. Jin became calm.

A kind smile on his face.

Just now he was surprised whether the X-rays were inaccurate.

But after watching all the X-rays, Mr. Jin felt relieved.

If there is something wrong with an X-ray, that would be understandable.

But there were problems with dozens of X-rays, which meant that the problem might be Mr. Jin himself.

Thinking of the upgraded tank Yan Hua drove on the training ground, Mr. Jin took a deep look at Li Yifan.

Sure enough, there are talented people from generation to generation.

To be able to design such a powerful tank, you must have your own ideas in tank manufacturing!

Mr. Jin and Li Yifan went to the cafeteria to have lunch and take a short rest.

Li Yifan then used a gantry crane to lift the V12 engine into the engine compartment of the tank.

Secure the engine feet with screws.

Then connect various wiring harnesses, such as the fuel injector wiring harness, ignition coil wiring harness, and various auxiliary electrical wiring harnesses.

After installing the first engine, Li Yifan then installed the second turbofan engine.

It wasn't until the entire engine room was filled that Li Yifan relaxed a little.

Although the engine compartment of the tank is large, it still seems a lot crowded when two engines are crammed into it.

Especially the second turbofan engine.

The width of this F135-PW-100 turbofan engine is acceptable, only one meter and two meters.

The length of the turbofan engine is unacceptable, at five meters six.

The total length of the tank body designed by Li Yifan is only more than seven meters.

It is absolutely impossible for the tank's engine nacelle alone to accommodate this turbofan engine.

So Li Yifan either tampered with the tank body or the turbofan engine.

But in order to adapt to land mobile units, Li Yifan made modifications to the turbofan engine.

The modification part of the turbofan engine is mainly at its rear end.

When a normal turbofan engine is in operation, the combustion heat of the engine is discharged directly into the atmosphere.

But Li Yifan's upgraded and modified turbofan engine added a sealed heat energy recovery device to its tail.

In the heat energy recovery device, there is an engine output shaft connected to the transmission.

This design not only saves fuel, but also shortens the length of the turbofan engine by nearly half.

After installing the engine, Li Yifan began to tinker with the tracks composed of rubber pads and steel.

After tinkering with the tracks, the fourteen road wheels were installed on the suspension of the tank body.

Finally, install the guide wheels and driving wheels together, hang up the tracks, and install the skirt.

After assembling the transmission system, Li Yifan came to the tank and began to arrange the cockpit.

Li Yifan completed the layout of various instruments in the cockpit.

Install a retractable height steering wheel, accelerator pedal and a series of accessories.

Eight days later, another tank came out.

Compared with the construction time of the first tank, this second tank took nearly half the time.

However, when assembling the tank accessories, Mr. Jin still called several scholars to come over and help.

Otherwise, Li Yifan would not be able to assemble it so quickly even if he was skilled in it.

However, just when Jin was celebrating, the phone rang.

Mr. Jin picked up his cell phone and saw that it was student Wei Yong calling.

Jin Lao swiped his phone and answered the call.

"Hey Xiao Wei!" said Mr. Jin.

"Teacher, you have answered my call. I have already called you three times."

"Teacher, the day after tomorrow is the military division exercise competition."

"There will be South China Military District Two and Military District Three coming."

"The Commander-in-Chief of the South China Military Region will come to watch the event in person."

"Teacher, you have to help the students!"

"Our South China Military Division has always been at the bottom in exercises last year and the year before."

"The boss has already spoken. If we are still at the bottom this year, then everyone will pack up and leave."

"Teacher, you have to help the students! You don't want to see the students reduced to the market!" Wei Yong said on the phone.

Mr. Jin frowned slightly, tinkering with tanks at the manufacturing site every day.

I only noticed the progress of upgrading and refitting the tanks, but not the time.

I didn't expect time to fly by so quickly.

Eight days passed in the blink of an eye.

"Okay, Xiao Wei, I understand. I'll arrange a tow truck for you right away."

"Ship the tank over immediately," Mr. Jin said.

"Teacher, can you arrange for an extra driver?"

"It's more than two thousand kilometers from Jincheng to Haishi."

"And I have a drill the day after tomorrow. Teacher, you have to help the students think of a way."

"Don't let the students disgrace you on the day of the practice competition!" Wei Yong said on the phone.

"Don't involve me if you're embarrassed."

After Jin Lao finished speaking, he hung up the phone with a flick of his finger.

"Classmate Yifan, this tank is now completed. Let's go and give it a try." Mr. Jin said.

"No, the functions and stability are the same as the first one." Li Yifan said calmly.

After hearing what Li Yifan said, Mr. Jin thought for a moment.

Decided to call a tow truck and tow the tank directly to Haicheng South China Military Division.

If I want to test the tank, I'm still a little worried about not being able to make it in time.

In addition, Mr. Jin watched Li Yifan's installation details of the tank in the past few days.

I am [-]% confident that this tank will not need to be tested.

......

Haicheng South China Military Division Office.

Wei Yong heard General Jin hang up the phone.

I had no choice but to put my phone on the table.

Tao Xiaogang saw this and asked:

"What's going on with Old Wei? What did your teacher say?"
