People in the Ming Dynasty are lawless

Chapter 277 The use of Eucommia rubber allowed Ming Dynasty to lead the world for at least several hundred years, not to mention the red cannon

Zhu Gaochi laughed very happily.

Because he saw the expressions on everyone's faces were very shocked, then his purpose was achieved this time.

What is his purpose?

He actually wants everyone to take a look at their latest research and development results, not just the red cannon.

Cannons are very common in today's Ming Dynasty.

Even Zhu Yuanzhang was very familiar with it.

Because when he had a water fight with Chen Youliang, the ship had already been equipped with a large number of cannons. This kind of thing was not new.

What's new?

What's new is that the wheel is actually wrapped with something dark, the material of which is not clear, but it feels very elastic.

Chen Han was even more pleased after seeing it, because he had already seen what was on the wheel?

After the cannon was pushed over, Lan Yu also discovered something was wrong.

He has seen a lot of cannons. Although the so-called red cannon today has a longer and thicker barrel, it still looks like a cannon.

It was only in the wheels that he saw a difference.

First of all, the wheels are not made of ordinary wood, but of iron. The hub and horizontal bar in the middle are also made of iron.

The most important thing is that the outside of the wheel hub is actually wrapped with a black unknown material.

This material is what makes him very strange.

He had seen a lot of wheels. In the past, in order to prevent the wheels from being severely worn directly on the ground, many wheels would be wrapped with a ring of leather.

Of course, this is only for wealthy people.

Most people still use wooden wheels.

But what is shown in front of them now is completely different.

The leather-like material on the interior is not only thicker, but also has patterns.

The most important thing is that such a heavy thing made no sound when pushed on the cement road.

They had been studying flintlock guns just now, and they were very serious about it, so it would make sense to ignore the sounds on the side.

But why was there still no sound when the cannon was pushed only five meters in front of them?

This is a bit strange.

Soon the three cannons were pushed in front of them. Lan Yu ran over first. He squatted beside the wheel and twisted the wheel vigorously.

He just wanted to see what this thing was.

The moment he saw Lan Yu, he found the key to the problem.

Zhu Gaochi and the others were even more happy.

Zhu Gaochi was even more excited when he saw that even his own imperial grandfather ran to the wheel to watch.

He walked up to Chen Han and said, "Sir, your Eucommia rubber is very useful.

We now use it not only in manufacturing tires, but also in machinery that requires airtightness.

The emergence of this thing has simply pushed all our current technologies to a climax. "

Chen Han had a smile on his lips.

The practical application of Eucommia rubber is Chen Han's greatest achievement.

The current rubber is still as far away as South America and has not yet reached Southeast Asia. There are no rubber trees there yet.

However, the gelatin extracted from domestic medicinal materials such as Eucommia ulmoides can also be condensed into rubber products, which can be used in daily life.

Especially for tires, especially for machinery that requires airtightness, it is very useful.

Even if the conveyor belt uses Eucommia rubber, it can achieve very good results.

Zhu Gaochi is right to say that it directly promotes the current development of science and technology.

He did not say that this was not his fault as he had done before.

Because the development of Eucommia rubber was entirely by his own hand.

Chen Han also went through a lot of experiments before slowly developing Eucommia rubber.

After more than a year of repeated experiments, the Eucommia rubber was finally formed.

Everyone has worked hard in this process, but the most important thing is Chen Han. A lot of hard work went into it.

To be honest, if Chen Han hadn't discovered that Eucommia ulmoides could extract gel and then slowly experimented, it would have been impossible to have such a good thing now.

Lan Yu stared at the tires.

Because he has never found anything better than this.

Now the use of tires has been tested on such a heavy fort and can be used anywhere in the future.

Zhu Yuanzhang was stunned for a moment when he saw the dark circle of tires wrapped on the iron wheel. Then he stepped forward and squeezed it with his hands like Lan Yu.

That's a rubber tire that's hard enough, but a little soft.

After reading it, he turned back and looked at Chen Han in shock, "Chen Han, is this the kind of rubber you said before that can be wrapped on the wheel? Have you already made it?"

Zhu Gaochi said on behalf of Chen Han: "Grandpa Huang, you are right, this is the Eucommia rubber that Mr. Wang has always emphasized before, which will definitely transform many places in the Ming Dynasty.

My husband synthesized this kind of rubber before, and after we kept testing and polishing it, it was finally used in tires.

After repeated tests, we found that the leather on the wheel can indeed protect the wheel from wear, but it is very limited.

Now that rubber is installed as a cushion, not only the protective effect is very ideal, but it also has a shock-absorbing effect.

We used to drag things back and forth on the cement road non-stop for over half a year without having to replace them. "

After Zhu Gaochi finished speaking, not to mention Zhu Yuanzhang and Lan Yu were astonished.

Even Zhu Youdun and others on the side knew for the first time that this tire had such an effect.

Each of them has a different direction of attack.

Zhu Gaochi mainly works on gunpowder weapons and Eucommia rubber, so he can know the benefits of Eucommia rubber at the first time.

“Since Eucommia rubber was put into use, it has brought us great shock.

Not to mention the surprise that this is the first time you have seen tires displayed in front of you.

Even those of us who have been dealing with Eucommia rubber still feel that Eucommia rubber is a godsend.

Not only is it very malleable, it can be used on conveyor belts and machinery that requires very good sealing.

Especially when used in the air tightness of our water gun and today's red cannon, it has an irreplaceable effect.

We are now able to achieve many achievements. We can stamp steel very quickly with water instead of manpower, and create hundreds of steel products. This is all thanks to the huge role played by Eucommia rubber. This tire made of Eucommia rubber is used on the wheels, which not only prevents wear and tear, but also increases the speed.

Everyone, you must know that you have a very profound experience of our previous wheels when riding in a carriage. They were extremely bumpy and the speed was not fast enough.

Sitting in a carriage, it won't take long for your butt to be overwhelmed.

But as long as tires made of our Eucommia rubber are used, these problems will not be a problem.

Because our Eucommia rubber has a certain degree of elasticity, when you sit in such a carriage and move forward quickly and confidently, your buttocks will not be scattered, and the resistance you will receive will be reduced a lot.

We have personally tested and compared the tires made of ordinary leather wheels with our Eucommia rubber at the same level and found that no matter the degree of fatigue of the horse, the degree of load, or the speed, the tires made of Eucommia rubber are better. The tires of the carriage are all better.

It will also be much more comfortable for people to sit on it. This is what I mean by the use of Eucommia rubber on carriage wheels.

At the same time, we used it on the wheels of the red cannon that now carries a weight of three thousand kilograms, and the effect is even more obvious.

Thanks to the role of Eucommia rubber, we only need two soldiers to push the cannon weighing three thousand kilograms, and it will not be too strenuous.

This is the best scientific and technological invention that Mr. Ming has brought to us.

It is a technological invention that can surpass all our research results.

Because Eucommia rubber is used in too many occasions. "

Zhu Gaochi was very excited when he said this.

Because he didn't find anything better.

The emergence of Eucommia rubber made Zhu Gaochi know that the Ming Dynasty would usher in a real new development from now on.

After listening to these words, Lan Yu and the others finally understood why two soldiers could easily fire such a heavy artillery piece. It turned out that it was all due to Eucommia rubber.

After listening to this, everyone suddenly understood, and they all gathered around the wheel of the artillery to watch.

Everyone was amazed.

"With this thing, if you install it on the carriage wheel in the future, you don't have to worry about breaking your buttocks?" Lan Chun asked.

Zhu Gaochi replied: Yes, reduce the bumps, and naturally the buttocks will not be scattered. "

Lan Chun was delighted: "That's great. There are many good things. I would rather ride in a carriage in the future."

Zhu Jixi said from the side: "Isn't that right? In the future, I won't be afraid of suffering when I have to go on long-distance raids with this good thing."

Of all the people here, who has not ridden in a carriage?

Riding in a carriage may seem convenient and comfortable, but it is not. The bumps are unbearable, so it is impossible to sit there often.

Even inside the carriage where the emperor sat, he could only put a thick quilt on it to prevent bumps, but it was still difficult to be comfortable.

And with tires made of Eucommia rubber, it reduces wear and vibration, which makes it much more comfortable.

Zhu Yuanzhang was shocked at this time because Chen Han once told him that after using tires made of Eucommia rubber, it would be very convenient for carriages to transport food or supplies.

And one carriage will reduce the loss a little. What if there are thousands of carriages, ten thousand carriages, or millions of carriages.

If they are all used, one carriage can reduce damage. Tens of millions of carriages is an astronomical figure.

Zhu Yuanzhang's eyes suddenly lit up when he thought of this.

He knew that the biggest thing Chen Han brought to the Ming Dynasty was the tire made of Eucommia rubber.

And it's not just used in tires.

What's more important is the use in all aspects.

Zhu Yuanzhang burst into tears.

Seeing these changes, he knew that the Ming Dynasty was about to usher in a new development.

What he may not know yet is that what Chen Han is even more excited about is that the successful experience of Eucommia rubber will be used more in steam engines in the future.

Because the cylinder of the steam engine needs to be very closed.

The better the cylinder is sealed, the more power it can generate.

In the original history, when the steam engine appeared, due to substandard materials and poor cylinder sealing, the efficiency of the steam engine was very low for a long time.

And now, even if the rubber from South America has not spread to Southeast Asia, and a large amount of rubber has not been obtained from there, rubber products have been extracted from Eucommia ulmoides.

Although its effect is not as good as real rubber.

But it can completely replace most of the functions.

After everyone saw that Eucommia rubber had achieved such results, their interest in the red cannon became even deeper.

They really wanted to see what kind of power this cannon, which Zhu Gaochi called a cannon weighing more than three thousand kilograms, had.

While the red cannon was being pushed over, Zhu Gaochi had already asked his soldiers to set the target farther away.

Judging from the position that the telescope can see, it must be at least 1,500 meters.

Chen Han explained to everyone on the side: "The maximum designed range of the red cannon is six miles, and the maximum killing range is about four miles.

In the past, all our cannons were made of copper and iron, but now that we have produced steel, we use it on the red cannons.

Such a cannon can be used longer. Its barrel has a long wall and is thickened gradually from the muzzle to the breech, which is in line with the principle that the pressure in the chamber changes from high to low during combustion.

There are cylindrical lugs on both sides of the center of gravity of the gun body. The gun can be used as an axis to adjust the elevation angle and change the range according to the amount of gunpowder. It is equipped with a front sight and a cover door. The ballistic trajectory is calculated according to a parabola, which is highly accurate.

Of course, he also has a big weakness, which is that he is too heavy, which is not conducive to mobility.

But now it is mainly intended to be used on navy warships to attack ships on the sea and deal with pirates.

At the same time, it was also placed on the city wall to deter foreign enemies.

Of course, we can continue to improve in the future, and we can continue to develop more convenient and faster artillery.

Of course, now that we have rubber tires, mobility has been improved to a certain extent. "

Chen Han knew very well that the red cannon was very powerful, but too heavy.

It's too difficult to pull with an ordinary car, but it's relatively better after the tires are installed.

What needs to be improved next is the power of the cannonballs.

After Chen Han finished explaining, Zhu Gaochi asked the soldiers to prepare, and then in front of everyone, three red cannons were fired at the same time.

The deafening sound shook the ears of everyone present so that they could not hear the sound for a long time, which shows how powerful it is.

And when they used the telescope to look at the pagoda-like stone originally placed opposite, they discovered that the stone had been destroyed long ago, and a large crater with a diameter of more than ten meters was left.

With such power, if it were hit on a city wall or a ship, it would definitely blow up the opponent with one shot and render it unable to resist.

The most important thing is that with such huge power, the shock alone has reached a shocking level...
