I tinkered with cars and built a super military industry

After Li Yifan finished eating, he took a brief rest and then got up to build a tank.

Yan Hua considered that Li Yifan was tired from traveling and asked him to go back and rest early.

But Li Yifan's temper did not allow it.

When he has something to do, Li Yifan likes to rest after finishing his work.

In another experimental building on the South China Campus.

Hua Gang is working with his mentors and students to prepare to rebuild an electromagnetic rail gun.

But consider the time and cost issues.

After some discussion, it was decided not to move to the original gun body.

Just build a new barrel and replace it.

But even such a simple barrel replacement is a time-consuming and labor-intensive chore.

Because the electromagnetic railgun placed in the laboratory is too large.

But in terms of size, it is about 24 cubic meters and the height is about 5 meters.

Replacing such a gun barrel requires a double gantry crane.

In terms of time and cost, it will take about a month at the earliest.

Moreover, one month is enough to install it. If you really want to debug it completely, one month is not enough.

When talking about a month, one instructor asked:

"Academician Hua Gang, the tank research team made a bet with us."

"Say we can build a tank equipped with an electromagnetic rail gun in one month."

"Isn't this a fantasy?"

"If we are just talking about making ordinary tanks, one month would be absolutely no problem."

"But they are going to install an electromagnetic railgun firepower system on this tank."

"According to our understanding of the electromagnetic railgun, the design of the electromagnetic railgun alone took more than a month."

"Not to mention the manufacturing of parts and assembly, you won't even see the electromagnetic railgun in a month!"

After hearing this, Hua Gang smiled casually.

"I didn't force them to bet."

"It's the new guy who is arrogant. I just took this opportunity to beat his arrogance."

"This bet is a small matter."

"I heard from above that there is some unrest outside now."

"Many other countries are misfiring."

"The superiors asked us to work harder, especially in our artillery research and development group."

"Although electromagnetic railguns are not yet popular, other artillery developments must keep up."

"Just in case the higher ups call you."

"We have two things going on right now."

"First, replace the barrel of the electromagnetic railgun."

"Second, it is mainly to speed up the production of some medium and long-range artillery devices."

"Strive to achieve what is required above, and we can produce it at any time."

......

Inside the production workshop of the tank research group.

Li Yifan patched all the seams on the car body.

If you follow the normal steps, the next step is to take an X-ray machine.

Because no matter whether it is repaired by a robotic arm or manually, some defects will definitely be missed.

It is absolutely impossible to recognize it with the naked eye.

The purpose of this is that the tank itself is too heavy, easily weighing thirty tons.

In addition, traditional tanks can reach [-] to [-] kilometers per hour when traveling at high speed.

And there is no road condition to talk about, just encountering mountains and rivers.

In such an extremely harsh environment, if the tank is welded due to weak joints.

Node deformation failures are bound to occur.

So not only must this step be done, but it must also be done very carefully.

It all depends on skilled workers using probes to search every corner of the tank.

Any error of more than 0.05 mm will have to be reworked.

Because an error of more than 0.05 mm will result in the inability to install a patterned weapon system.

But Li Yifan can completely omit this step.

Because his system scan is many times more accurate than the X-ray scan.

Even if there is a slight error, Li Yifan's system can scan it out.

Skip this step, all that needs to be moved now is the transmission and gasoline-electric engine unit.

This step is actually not difficult, because when manufacturing the car body frame.

There are mounting locations for both the engine and transmission.

Compared with the gasoline-electric hybrid transmission, Li Yifan uses a traditional ECVT hybrid transmission device.

This is a torque converter with a locking clutch.

It is an automatic planetary transmission with dual differentials and a hydrostatic steering device.

This hybrid transmission can deliver 1200hp-1500hp.

Suitable for tanks weighing 50T to 60T.

Its biggest features are compact structure and light weight.

The weight without the braking mechanism is only 1850kg.

The overall length, width and height are 1030mm*1560mm*670mm, which is also much smaller than other transmission mechanisms.

Li Yifan used a gantry crane for the automatic transmission and a hanger to fix the hybrid transmission on the tank body.

After this operation, it only took more than half an hour to complete the installation.

As for the technology of gasoline-electric hybrid, it is not the most difficult.

The most difficult thing is the power source of the electromagnetic railgun.

Although there is no turret installed yet, the power supply mechanism of the electromagnetic rail gun is all arranged in the car body.

The reason why the electromagnetic railgun is huge is because its power supply mechanism accounts for a large proportion.

The electromagnetic railgun cannot be circulated now because it is too difficult to store energy.

According to the current most advanced level.

As far as energy storage units are concerned, more than seven military shelters must be arranged.

Each size must be more than 25 cubic meters.

Such a huge power supply configuration can only be used on landing ships.

If you want to put it on a destroyer, it must be reduced.

Otherwise, even the 055-class destroyer cannot accommodate such a set of electromagnetic guns.

However, these problems are relatively simple for Li Yifan.

He just needs to replace the lithium power supply with a power supply made of graphene.

Li Yifan rummaged around the tank workshop and actually found a DVD optical engraving recorder.

And in a pile of materials, graphene was found.

But they were all covered in dust.

Li Yifan couldn't care less, so he directly used a DVD light engraving recorder to cut the graphene.

At this moment, it was one night, and Li Yifan was sleeping in the workshop when he was sleepy.

I woke up and continued to carve.

It stayed like this for three days and three nights.

During this period, Yan Hua asked Li Yifan to go to the dormitory to rest, but Li Yifan refused.

Because once he starts doing something, he only has work in his eyes.

What's more, this is the South China Military Institute, and Li Yifan doesn't like wandering around in an unfamiliar environment.

So I just ate, drank, and slept in the tank production workshop.

After finishing the work in a few times, I went home. I still don’t know what the big villa in my hometown is like.

I really want to go back and take a look.

After another two days, three days and three nights, Li Yifan finally made graphene the electricity storage unit of the capacitor.

After nine days and nine nights of carving, a square-sized battery was finally produced.

The thickness of this power supply is about ten centimeters.

The interior is composed of more than [-] graphene capacitor storage units.

It doesn't look like much, but Li Yifan knows that this thing will be amazing on the day of testing.
