Military Industry: On the eve of the Anti-Eagle War, unlock the skills of a strong country

I think this thing shouldn't be difficult.

After all, in later generations we can get free shipping for 9 yuan, but now we are just starting from scratch.

After some checking, I found that the main structure of this thing is not much, and there are only a few core keys.

The important thing is something called silicon wafer.

However, in order to obtain high-purity silicon materials, chemical purification methods are usually used to convert industrial silicon into polysilicon.

A diffusion furnace is needed here.

The polysilicon is then made into single crystal silicon rods through a diffusion furnace and cut into thin silicon wafers. The surface of the silicon wafers is then cleaned and polished to remove impurities and damaged layers.

Then, diffusion doping is performed on the surface of the silicon wafer to form a PN junction, which is the key structure for solar cells to achieve photoelectric conversion.

Then carry out operations to improve the efficiency of suction team,

It sounds difficult, but it's just depositing a layer of anti-reflection film on the surface of the silicon wafer, such as silicon nitride or silicon dioxide, which can reduce the reflection of light and improve the efficiency of light absorption.

In this way, it is basically completed.

Once those plates are made, metal electrodes are made on the front and back of the battery. The front electrode usually adopts a fine grid line structure to reduce the light-shielding area; the back electrode covers a larger area to facilitate current collection.

Then there are the battery components, inverters...

Basically, you can learn these things at a glance, but fail as soon as you try.

Zhang Tian smiled bitterly. This thing sounded simple in the information, but it was actually quite difficult.

But since we are planning to do this, we have to do it no matter how difficult it is.

Qin Dongtian was called and given a task.

That is to build a diffusion furnace first. This is the prerequisite for making the silicon wafer structure of the solar panel.

It's not difficult to make, just leave it to him.

You have to take your time with this thing, there is no rush because none of the things listed above exist, you have to get everything done one by one.

Then there's no need to rush.

Zhang Tian plans to complete it within half a year. As long as a sample can be developed within half a year, large-scale production can be carried out.

Will there still be power shortage by then?

Qin Dongtian took the information with a look of disbelief: "Director, is this solar power generation you mentioned true or false? I have only heard of using coal to generate electricity."

“Can light generate electricity?”

Zhang Tian smiled. Qin Dongtian's reaction was within his expectations.

Even if he were the one doing the teaching, he would still not believe it.

"Director Qin, I can't explain this to you right now. Just do as I say."

"You can call on all the people who produce hydroelectric parts. Just follow the information I give you and proceed step by step."

Qin Dongtian looked at Zhang Tian suspiciously, then nodded.

Although he was a little skeptical in his heart, Zhang Tian was the boss.

He just executes it.

Anyway, Zhang Tian never plays by the rules.

Every now and then it's something they haven't seen before.

After Qin Dongtian went out, Zhang Tian shook his head slightly. He still had his own things to do.

His attention is now focused on a piece of heavy equipment within the system.

This is a tank.

This was the prompt the system gave him after he received the reward value for the anti-aircraft gun.

It keeps spinning around on top.

This was a reminder to him that it was time to produce heavy tanks.

Come to think of it, we have all kinds of guns and cannons now.

We are still short of this heavy weapon equipment for assault.

There are several types of tanks, but Zhang Tian himself prefers heavy tanks because their performance is simply incomparable to those of light and medium tanks.

Heavy tanks have powerful firepower configurations and large-caliber main guns that can fire shells with powerful power and penetration, causing huge damage to enemy armored targets, fortifications and defensive facilities.

Especially in this day and age, this kind of heavy equipment is often the most effective in undermining the enemy's combat psychology.

Just think about it, the heavy tanks have thick and solid armor protection, which can basically ignore the attacks of current enemy tanks and anti-tank weapons in this period.

Besides, how many countries have tanks now?

If you count them over and over again, you can count them all with one hand.

However, such powerful firepower and thick armor also require that heavy tanks have a higher weight. In production, both the power system and the suspension system have higher requirements.

The disadvantage is that it is too heavy.

It runs a bit slowly and has relatively poor maneuverability. Its driving speed and turning flexibility may not be as good as medium tanks and light tanks.

However, force can defeat skill.

These are not a problem. As long as we have a tank company made up of steel beasts, what's in front of it?

Just run over it.

If you can't catch up, then fire one shot. If that doesn't work, then fire a few more shots.

In fact, Rabbit also independently developed a heavy tank in the late 1950s and succeeded, but then abandoned it.

The cause was the rabbits of that period, an army of several million people had only a few heavy tanks.

200 vehicles.

They were all Soviet-style "Joseph Stalin" heavy tanks.

When the leaders thought that such a great country only had so few tanks, they became uneasy and issued a design assignment in October 1960 to independently develop heavy tanks.

The tank was code-named 111 and later called wz111.

However, the industrial conditions at that time were indeed not up to par, and many data still could not meet the standards.

Take the 111 vehicle body for example. Due to the limitations at the time, the body was welded and cast from rolled armored steel plates.

Note that they are all welded.

The thickness of the armored steel plates on the front part from top to bottom are 60, 120, and 130 mm respectively. Then the front steel plate of the armored turret is 200 mm thick, the rear is 80 mm thick, and the top deck is 25 mm thick with two hatches.

It is not an exaggeration to say that it was simple, but it was the only way possible under the conditions at the time.

In terms of power, it uses a 12-cylinder 520-horsepower diesel engine, which is said to be a copy of the Soviet V-11 engine and has a high failure rate.

At that time, the first wz-111 heavy tank test sample was produced. It was very fast, but this tank had no turret. Instead, it had a flat cab with the same weight as the turret.

The development of the turret encountered difficulties, mainly because the breech block of the tank's rifled gun was too large, making it difficult to effectively combine the interior of the turret and the fighting compartment into a whole in the proper form.

The root cause is technical limitations.

Then, due to various technical reasons, the requirements for the engine and armored body could not be met, and the heavy tank development project was stopped four years later.

This unfinished tank is still in the museum.

Zhang Tian turned his attention back to the system.

Then it stopped at the main battle tank that could compete with the Eagle Sauce in the future.

Dual 9A tanks.
