Siheyuan: Heavy Industry Revitalizes the Country

"Is this a heavy truck? We are not professionals!"

Cao Tianwei looked at the thick pile of drawings on the table, and sweat instantly broke out on his forehead.

The other members of the group also looked at each other in confusion.

"The Dongfanghong tractor was just a two-cylinder diesel engine.

Back then, we studied it for a year but made no progress.

If you, Fang Xiang, hadn't come, we would probably have continued to waste time.

后来的CA-10是6缸汽油机、BN492是4缸汽油机、CA-72是8缸汽油机。

To be honest, although we knew a little bit, we hardly contributed anything.

To be fair, I was just helping you out, but I got a lot of attention and learned a lot.

But the 6-cylinder diesel engine of this heavy truck really involves our blind spot in knowledge. "

Cao Tianwei stroked the drawing of the LT665 engine, with an obvious burning light in his eyes.

But he said some discouraging words.

"Everything is difficult at the beginning. There is a first time for everything. Doesn't this make up for our shortcomings?!"

Fang Xiang had eaten countless cakes in later lives, so it was natural for him to come up with words of comfort.

"The First Ministry of Machine Building said that if the results of this project satisfy them,

Together with the Dongfanghong and Hongqi projects, they will apply for a certificate of award for us.

Moreover, maybe the professional title can be upgraded to a higher level.

However, the time frame will be tight.”

Then, he also mentioned the benefits that Director Yin had promised.

"Third class merit? Two third class merits in one year? Did I hear it wrong?"

"The situation has been opened up. This time, three projects are applied for together. I bet it will be a second-class merit!"

"Second class merit? Is this something I can get?"

"One second-class merit, one third-class merit, I'm willing to die!"

"That's great! I can go to a good company next year!"

“Don’t forget the job title!!”

"Yes! And there are professional titles! Two professional titles in one year? Am I dreaming?"

"A second-class merit for the title? Quick! Slap me!"

"Snapped!"

"It hurts! It's real! I'm not dreaming!"

Cao Tianwei was speechless as he looked at the members of the scientific research team who were almost going crazy in the office.

Others don’t know clearly, so why doesn’t he know clearly?

They didn't even study the tractor engine project thoroughly.

Now the difficulty of heavy-duty truck engines has increased by more than two levels.

The carrots hanging in front of you seem so bright and delicious.

But he knew in his heart that what was the point if he couldn't eat it.

“It’s the whole vehicle, not just the engine.

Although most of the drawings have been designed.

But many areas have not yet been demonstrated and verified.

This is a project that is more difficult than the previous three projects combined.”

Fang wanted to pour a basin of cold water at the right time.

Although he also knew that it was not quite fair to use these rewards to trick the research team.

But he knew even more clearly that this research team would have to wait until there was no next project.

Maybe by the time school starts, it will be no later than the end of the year at the latest.

I'm afraid they will be disbanded and everyone will divide their things.

Although the Dongfanghong heavy-duty truck project is difficult, fortunately the foundation has been laid.

Even if it needs to be changed, it will just be some patching and minor repairs.

What's more, he had a complete set of Scania's drawings and information in his mind.

Thinking back to the time when Fang was studying at university before he traveled through time.

My roommate is a crazy Eurogamer 2 fan.

How obsessed are you?

He bought a hard drive from somewhere.

It is filled with heavy truck information and detailed drawings of Scania, Mercedes-Benz, Foton and Weichai.

Apart from attending classes every day, I look at these drawings.

I only go on a long-distance trip when I feel too sleepy to bear it anymore.

As I was doing this, I fell asleep in front of the computer.

Thanks to this roommate, Fang Xiang was aroused by his crazy obsession.

I occasionally look through these drawings.

Before I knew it, I had finished reviewing all the drawings after half a semester.

Of course, at that time Fang Xiang was only curious.

After all, his major is aerospace, not ground vehicles.

So, I just finished watching it.

But unexpectedly, this time I was blessed with time travel.

His extraordinary memory allows him to recall the drawings he has seen anytime and anywhere.

All have the opportunity to reappear one by one.

“But there is no need to worry too much.

The project is difficult, but not to the point of being unsolvable.

Let’s start with the easiest engine.”

After pouring cold water on them, Fang Xiang gave some appropriate boost to the morale.

But he forgot that, in his opinion, it was a very simple matter.

But for these team members, that was already the technological difficulty of Zenith.

Although it sounds a bit Versailles, Fang Xiang still hopes to keep this group together.

It would be best if I could hold on until next year, and then find a way to lead myself.

After all, they are all students taught by Professor Xu.

To exaggerate a little, it may be a bit of an exaggeration to say that I know everything about it.

The trustworthiness has at least reached the passing line.

As for technical and scientific research capabilities?

It does not matter.

You Fang thought that these people would be the most ideal helpers.

Be able to help him do some repetitive and boring work.

And those are the key points that need to be tackled and the areas that need to be adjusted and changed.

Then Fang Xiang can do it himself.

After saying that, Fang wanted to find a blank design drawing.

Place the original drawing of the LT665 engine aside for reference.

I started drawing a new picture stroke by stroke.

By the way, the LT665 is based on a Czech Tatra 8-cylinder air-cooled 4-stroke engine.

It is an extended and upgraded version of the LT8120F air-cooled diesel engine developed based on the previous model.

The current parameters are 180 horsepower, 132kw power, and 706 Nm of torque.

The whole vehicle has a 6*6 drive mode.

The structural parameters are: 7100mm*2500mm*2696mm.

Wheelbase 3890mm.

From the rear axle to the rear suspension center, the center distance between the rear axle and the rear axle is 1320mm.

Minimum ground clearance 390mm.

Weight: 9000KG.

The load capacity is 5000KG for off-road and KG for road.

Maximum towing weight, off-road 6000KG, road KG.

Maximum speed: 81km/H.

Maximum climbing grade, 58 degrees.

Maximum obstacle crossing height: 0.66 meters.

The maximum trench width is 1.1 meters.

Maximum wading depth, 1.2 meters.

Minimum turning radius, 10 meters.

The average fuel consumption is 35 liters.

If you look at the data alone, there doesn't seem to be any problem.

Then let’s take a look at the Jiefang CA-10 truck. It can easily transport goods and people.

But if it comes to pulling artillery, it's not very capable, especially in terms of off-road capability, which is almost non-existent.

So now FAW has another military light truck designed specifically for off-road use, the CA-30.

The body structure is 6684mm*2315nn*2360mm.

Weight: 5450KG.

The road load capacity is 4.5 tons.

Off-road load capacity is 2.5 tons.

Towing load 3.6 tons.

The maximum highway speed is 65 km/h.

The minimum turning radius is 12.1 meters.

Maximum climbing grade 30%.

The wading depth is 0.85 meters.

Although it also has a 6*6 chassis, the engine is the same as the Jiefang CA-10.

Fang Xiang just finished designing the CA-10C.

The horsepower is only 115 and the torque is 36KG Nm.

Therefore, a very intuitive comparison result came out.

The problem with the CA-30 is that it is difficult to pull a small 75mm caliber artillery on flat ground.

It's still acceptable.

But once it comes to 125mm medium caliber artillery.

If you encounter some roads that require strong off-road capabilities, you can only watch helplessly.

Of course, the data of LT665 is just usable in China at this time.

At least for calibers of 125mm and 155mm, it has the ability to pull.

But it certainly cannot be said to be excellent. After all, the domestic topography and geographical environment are very complex.

That is why the country is so eager to use foreign exchange to exchange for a complete set of heavy truck drawings.

Speaking of which, heavy trucks are a completely blank area in China today.

Previously, they were all imported from the Soviet Union.

But in the 60s, the close relationship between the two countries broke down.

Naturally, this condition is lost.

It’s just that heavy trucks are a very professional type.

There is almost no possibility of research and development on my own.

Fortunately, there were still a few capitalist countries with which we could interact at that time.

Take Gaul for example, they will sell it for money!

So, what are the data of the heavy truck purchased this time?
