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

In the blink of an eye, another three days passed.

Minister Wang had not sent back any news about what had happened that day, so Zhang Tian had no choice but to wait.

Work on the tank engine block finally made progress, which was also a coincidence.

Qin Dongtian simply changed a smaller cutting tool to cut the cylinder body, and unexpectedly it worked just fine.

How do you say this?

A bright future?

Zhang Tian looked at the cylinder, not knowing whether to laugh or cry.

I didn't expect that the data in this system would be wrong. The tool number 4 it suggested was not suitable, but the tool number 5 was just right.

Is this a BUG?

Zhang Tian shook his head.

Let’s not worry about this for now. The most urgent task right now is to build the engine first.

After looking at it, it seems that it is waiting for this cylinder.

In the past few days, the internal parts such as crankshafts and connecting rods have basically been ground out using machine tools.

Those small parts are also being processed intensively now.

A day later, the other parts were almost prepared, and Zhang Tian simply waved his hand.

Start assembling.

The engine is the core power source of the tank, so its importance is self-evident. After having someone clean the assembly area, Zhang Tian carefully checked all the parts that were about to be used.

There can be no mistakes here, the quality and specifications must meet the requirements.

Otherwise, installing it will also be a hidden danger.

Everything was ready, and someone brought all the parts over. Zhang Tian took a deep breath.

Begin by installing the engine's crankshaft.

Qin Dongtian and the others were helping on the side, but now they didn't even dare to breathe.

I was afraid of disturbing Zhang Tian.

This is a fucking engine.

Strictly speaking, this is the first engine produced in China.

Zhang Tian first gently placed the crankshaft into the bearing seat of the cylinder block, used special tools to ensure its installation position was accurate, and carefully adjusted the axial and radial clearances of the crankshaft to achieve the best operating effect.

Then comes the assembly of the connecting rod and piston.

The piston and connecting rod assemblies are all produced by ourselves, so you can use them directly. Apply some engine oil on the piston ring, and then firmly connect the small end of the connecting rod to the piston pin.

Next, carefully place the assembled connecting rod and piston assembly into the cylinder, and observe carefully whether the piston moves smoothly in the cylinder and whether the gap between the piston and the cylinder wall is up to standard.

Since it was my first time assembling it, I would be lying if I said I wasn't nervous. The two steps above took me almost a whole morning.

Don't ask why it took so long.

The question is, I am new to it and have no experience.

"Director, is it done?" Qin Dongtian saw Zhang Tian stopped and hurried over to ask.

He had never seen an engine and thought that was it.

Zhang Tian shook his head, "It's not that easy. This is not even the halfway point."

"Bring me all those valve parts over there."

Qin Dongtian did as he was told happily.

The valve part is a bit simpler. You just need to accurately install the valve spring, valve guide and valve seat ring, and then adjust the valve clearance.

It's fine as long as there is nothing wrong with it, the opening and closing time of the valve is accurate, and it can open the intake and exhaust effects.

Then there are the fuel injectors, fuel lines...

After these key components were installed, Zhang Tian began to install the engine's timing system.

He doesn't use a timing belt, he uses a timing chain.

This is important. It is to ensure the synchronization of movement between the crankshaft, camshaft and valves to maximize the effect of fuel.

By the time I finished all this, it was already afternoon.

At this time, everyone's stomach was growling with hunger.

We stopped and let everyone go to eat.

The rest are just some accessory parts, which is very simple.

There is no need to rush at this moment.

After coming back from dinner, Zhang Tian installed the oil pump, water pump and other accessories in one go.

This way the engine has both lubrication and cooling systems.

I checked it again carefully, trying to avoid having too many extra parts and screws during my first assembly.

In later generations, won’t we often see videos like this?

The engine was installed, but there were a few extra screws.

After confirming that there were no problems, Zhang Tian asked someone to fix the engine. Now he was going to start the first truly autonomous engine in Rabbit's history.

I don’t have time to think about how far ahead I am of others.

Success comes first in making it ring.

Suppressing his nervousness, Zhang Tian pressed the fixed engine start button.

When the engine just started, a low and powerful "boom" sound rang out in the workshop, as if a sleeping beast was awakened.

Qin Dongtian and others were so happy that they all gathered around.

Now that it has sounded, does that count as a success?

Zhang Tian stepped on the accelerator again. As the engine speed gradually increased, the sound of the engine became compact and continuous. The sound was like rapid drum beats, with a brisk rhythm and powerful feeling.

Zhang Tian was delighted.

It seemed that he had succeeded, so he stepped on the accelerator again. He wanted to see what the top speed would be.

Soon, the sound of the engine was like roaring thunder, and the "boom boom boom" sound was deafening, and seemed to be full of violent and unstoppable momentum.

Zhang Tian smiled.

That's what a 1500 hp engine should do.

If this engine is improved further, it may even be used in aerospace applications.

After turning off the engine, the workshop became quiet.

Everyone looked at Zhang Tian.

"Everyone, we succeeded. We got the engine." Zhang Tian announced loudly and excitedly.

The workshop suddenly became noisy again.

"My dear mother..."

……

The focus of the Yangcheng factory now is on tanks. Now that the engine is out, the next step will be the body and supporting facilities.

Zhang Tian divided everyone into several groups, responsible for the various systems on the tank.

He takes the lead in the most difficult aspect of information communication.

When we were busy and having fun, Yang Jiaming came over again.

He brought a large group of people with him when he came.

Not many, maybe over a thousand.

I came here this time to fulfill the agreement I made with Zhang Tian.

Help him cultivate the wasteland in front of the factory.

The account for bullets has also been settled. Last time, Zhang Tianyi’s anti-aircraft gun was used to pay for it.

Zhang Tian took out all the seeds that he had prepared long ago.

Of the three hundred acres of land, two hundred and thirty acres are planted with hybrid rice, and the rest are planted with beans and vegetables.

Hybrid rice has always been something Zhang Tian wanted to promote vigorously.

In his opinion, this is more important than weapons and equipment.

The current rice yield is basically around 500 to 600 kilograms per mu, but Zhang Tian’s hybrid rice is different.

The yield per mu can reach 2,000 kilograms, and it can be planted for two seasons.

It is resistant to diseases, insect pests, floods and droughts, and has high yield. What else is suitable for it to use to survive the disasters in the next three years?

Yang Jiaming chuckled: "Brother, you said I helped you so much, can you reward me something this time?"

Zhang Tian rolled his eyes at him in annoyance when he heard that.

"Brother, we have already agreed on this. You help me farm and I will give you a rifle. What else do you want now? I have a tank in my workshop. Do you want one?"

"Haha, you just know how to brag." Upon hearing that, Yang Jiaming happily ran into the workshop.

He doesn't believe in building tanks or anything like that.

Maybe this kid is working on something new.

Unexpectedly, Yang Jiaming ran out less than two minutes after he went in, and the playful smile on his face turned into a serious expression.

He shouted loudly to the outside: "Company 1, put down your work, take your equipment and surround the arsenal. No outsiders are allowed to approach."

Zhang Tian was stunned for a moment.

What does Yang Jiaming want to do?
