Siheyuan: Heavy Industry Revitalizes the Country

The convoy arrived at Institute 402 in the west of the city. Fang Xiang didn't take the morning's incident to heart at all.

When Xiao Cheng asked him what happened and what to do next.

Fang wanted to just say it simply and lightly.

"Don't let him out anymore."

Just this one sentence completely destroyed the hope of a good joke coming out.

Yes, Fang Xiang’s words now can determine the fate of many people.

Bang Geng is definitely among them.

After arriving at Institute 402, this institute, which is more than kilometers away from the urban area, looks like an ordinary engine research institute from the outside.

But in fact, he is the famous Northern Vehicle Research Institute.

After the founding of the People's Republic of China, a series of armored vehicles of the military, including amphibious tanks, infantry fighting vehicles, main battle tanks, explosion-proof vehicles, roadblock vehicles, etc., were almost all developed here.

Before becoming the designer of J-112 at Factory 10, Fang Xiang also stayed here for a few years.

Of course, at that time he was mostly traveling between Henan Province and here.

So of course I am very familiar with this place.

After entering the test site, we soon saw the familiar test car running on the site.

“Most of the data have exceeded or are close to the original design indicators.

But now, the only things left to develop are the engine, the aiming system and the gun barrel.

Junior Brother Fang, you are not familiar with the aiming system and the gun barrel, so let’s leave it aside.

But you have to do something about the engine."

Qin Jun took out a cigarette from his pocket and handed one to Fang Xiang.

Fang Xiang already knew what Qin Jun was talking about.

Not only now, but also for a considerable period of time in the future, these three items are the shortcomings of domestically-made tanks.

The first technological breakthrough was in gun barrel technology. There is nothing much to say about this, as long as the money, basic science, materials and technology are in place.

You can climb up the technology tree by spending money on experiments.

Then the breakthrough was in the engine, and everyone may know the 99A.

At the beginning, the Type 99's engine power was less than 1000 horsepower, then it reached 1200 horsepower, and finally, it even broke through to 1500 horsepower.

But the gun aiming system was the only thing that was stuck and causing great discomfort.

It was also thanks to the good relations with foreign countries in recent years, including after the Soviet Union went bankrupt and split, we obtained drawings and production lines from several countries.

Only then did we make up for this last shortcoming.

There is no way. There are too many debts owed in history, and many things cannot be made up in a short period of time.

What’s more regrettable is that even though the 99A became the world’s top tank, it missed the era.

Yes, then it became the era of drones, and everyone knows that.

Fang Xiang naturally knew it, but he couldn't say it!

He can't just say, oh, forget it, these are all things that will be eliminated, let's play with drones instead.

The reason why drones were developed and flourished in later generations.

This is due to the integration of batteries and circuits.

Batteries are actually easy to deal with. Since the invention and popularization of lithium batteries, the world's battery technology has basically not been innovated for decades.

It seems to be exaggerated, but in fact, it is still the same, and there is no obvious difference in battery capacity.

Not to mention circuit integration, which is still on the road to miniaturization.

As long as science and technology has not made a breakthrough to the nano level, circuit integration and other technologies will not be able to keep up.

Apart from anything else, remote control and reception alone is a very difficult problem to solve.

In later generations, a receiver as big as a fingernail and a remote control the size of a handle made it possible to operate a drone comfortably.

In this era, it is definitely black technology.

Including the electric car that Fang Xiang had always dreamed of, it had never been put into action because of the chip technology and circuit integration that were lagging behind.

"Let me see the engine drawings first."

Fang Xiang finished his cigarette before reluctantly taking his eyes away from the sample car.

"Let's go back to the office."

Qin Jun also threw the cigarette butt to the ground, stepped on it and put it out, then turned around and led the way.

Fang Xiang, his secretary and several students followed him.

This was the first time Fang Xiang brought students out. Xiao Cheng was okay, as he had been following Fang Xiang around for years and had already seen or heard about him.

On the contrary, it was the students who came to the confidential unit for the first time and saw the most advanced research and development projects in the country.

Each one more excited than the other.

The four of them gathered together and chatted excitedly.

Fang Xiang, Qin Jun and others were not surprised by the performance of the graduate students.

When they first took over the project and pushed forward, there was a lot of excitement.

These students were recommended to Fang Xiang, and the screening behind them had to go through countless times.

Naturally, I am not worried about them.

However, when it comes to the most core things, the drawings, Fang wants to know that their confidentiality level is not enough.

He turned around and told Xiao Cheng to take them around to observe and learn.

I went to an office alone with Qin Jun.

“The basis of the blueprint was drawn by you.

After you went to Factory 132, we made some small-scale changes and adjustments.

You all know the specific reasons, so I won’t go into details.

Now the engine data in all aspects are not ideal, maybe it is related to the adjustments made.

However, due to technical and material strength issues, it cannot be verified.

I really had no choice but to invite you back."

Qin Jun took out the key from his pocket, opened the safe, rummaged around inside for a while, then pulled out a few drawings and placed them in front of Fang Xiang.

"So many changes?"

In fact, Fang Xiang knew nothing about diesel engines. At least he was a complete novice when it came to tank engines.

But don't forget that he had seen the drawings of Mercedes-Benz, Scania and Weichai before.

Yes, it was thanks to his roommate who loved playing Euro Truck Simulator.

So when Institute 402 invited him to participate in the research and development of Project 74, Fang Xiang initially refused with great trepidation.

But he really couldn't stand Qin Jun's repeated pulling, so he decided to come over and take a look at the situation first.

But after I got there, I realized that it was not a big deal. After I looked at it, I compared it with the diesel engine in my memory, and I was really amused.

How big is the truck's engine?

At most, it’s only half a cubic meter.

But how big is the tank's engine?

The starting point is one and a half cubic meters!

Can't I just zoom in?

You don't say it, you really don't say it, Fang Xiang took out the enlarged diesel engine and made a sample.

It directly shocked all the big names in the domestic diesel engine field.

It even alarmed the Sixth Ministry of Machine Building, which was the Ministry of Shipbuilding Industry at that time.

All the engines that are considered weak points on tanks are not a problem when placed on ships.

Soon, the Sixth Ministry of Machine Building improved the engines based on this batch and directly equipped a large number of patrol boats with new engines.

Of course, destroyers are definitely not a possibility, that is another concept.

Later, the Sixth Ministry of Machine Building repeatedly invited Fang Xiang to participate in the design of destroyer engines, but Fang Xiang refused to go no matter what.

You know, at the destroyer level, the horsepower is often in the tens of thousands.

For those who have higher aspirations, the starting horsepower is 100,000.

Fang Xiang has never seen or understood it. Wouldn't it be embarrassing to go there?

“There’s no way, the design specifications are high, and your drawing specifications are also high.

But the reality is that it is impossible to produce it, so we have to lower the standards and make changes.

After many changes, it finally became usable, and now it is like this."

Qin Jun took out another cigarette and spoke in a helpless tone.

"You have access to more materials than I do. If you can't handle it, there's no point in me taking over, right?"

After looking at the comparison chart and indicator table, Fang Xiang refused the cigarette Qin Jun handed over.

shook his head.

"What should we do? We can't just ignore it, right?"

As soon as Qin Jun heard Fang Xiang's words, he knew what he meant.

After all, Institute 402 is the top scientific research institute in the country, both in terms of confidentiality level and authority.

They are much taller and bigger than the GAC where I work.

Basically, the most cutting-edge and latest materials, there is no 402 that you can't get, only what you don't want.

As soon as these words came out, the expression on Qin Jun's face suddenly fell.
