Daming: Old Zhu, we agreed not to rush!

Chapter 271 Firecracker transformation, shotguns and sniper rifles!
Baoyuan Bureau is still working in full swing.

Because of the support of the entire Daming top technical team, plus material support regardless of cost.

Su Jing put forward higher requirements for the firecracker he will do next.

Just simply making a flintlock gun, wouldn't that be a shame for these master craftsmen.

Therefore, Su Jing thought of a gun, a very simple gun in his previous life: FP-45 Liberator pistol.

This is a firearm whose structure is so simple that Su Jing in his previous life can find the structure diagram just by searching the Internet casually.

Not only that, like some toy factories have also made assembly toys for the FP-45 Liberator pistol.

The fact that such a situation can occur with a firearm can only explain one problem, that is, its structure is really simple.

All the components add up to only 23 in total.

This is a pistol developed during World War II, with 23 parts, including all the spring jams and other parts.

Assembling this gun, skilled workers, only takes 6 seconds.

Of course, because of its simple structure, its shooting accuracy and killing range are quite limited.

The FP-45 Liberator pistol was invented not for large-scale combat, but as a means of quickly arming civilians.

This firearm was destroyed shortly after its historical significance ended.

But now, it is Su Jing's best choice.

Because the level of science and technology of the Ming Dynasty is different from Su Jing's previous life, it is not 01:30.

It is the FP-45 Liberator pistol. Su Jing is still a little uncertain about making it.

But this is already what Su Jing can think of, and it is the most likely modern firearm to be made under Daming's technical level.

Su Jing soon encountered the first problem.

A part that basically exists in all modern firearms.

spring!

Su Jing didn't know how to make the spring, so he could only tell the craftsmen the shape and characteristics of the spring, and let the craftsmen study it.

But for springs, it is definitely not possible to rely on direct casting. What is cast in that way is just an iron piece with no shape but no internal stress.

Therefore, the spring can only be forged manually by craftsmen.

A spring is also needed in the flintlock, but Su Jing uses a clockwork spring instead, but this FP-45 Liberator pistol needs a coil spring.

At this time, the problem reappeared, and regardless of whether the forged spring is uniform and fine enough, it is very difficult to produce spring steel for the spring.

If you want to make springs, you must not use ordinary steel.

The spring uses its elastic deformation to absorb and release external force, so the spring steel is required to have a higher elastic limit and good resistance to elastic decline, and a higher yield ratio. In order to prevent fatigue or fracture under alternating stress, it is also required to have High fatigue strength and sufficient plasticity and toughness.

In terms of process performance, sufficient hardenability is also required.

The influencing factors of hardenability are alloying elements, and the influencing factors of plasticity and toughness are alloying elements and heat treatment.

In addition, there are materials, which require high metallurgical quality and organizational uniformity, control internal and surface defects, and do not allow cracks, inclusions, severe decarburization, etc. These defects often become places where stress is highly concentrated and crack fatigue sources, so that Reduced fatigue strength…

These things were the most basic in Su Jing's previous life.

It's just that for the current Ming Dynasty, all of them are the most advanced and cutting-edge technologies, even technologies that have not yet appeared.

Su Jing is really in trouble now, he never thought that the simplest gun in his previous life would be so difficult to make in Daming.

industrialization!
Only industrialization can make these things easier.

But industrialization is too difficult for the Ming Dynasty, which is dominated by an agricultural society.

At least, let's have an industrial revolution.

Just thinking about Su Jing makes it impossible. The disadvantages of the feudal unified dynasty are also highlighted at this time.

The emperor ruled the world, and what they most wanted to do was not to make scientific progress, but to maintain their own rule.

Although the West also has rulers, in a state of division, it is difficult to unify thoughts, and thoughts that are difficult to unify tend to burst out different things.

This is not to belittle oneself, it is just the fact.

"Mr. Su, can you take a look at the spring I made?"

Another craftsman came to Su Jing and handed the spring that had just been forged to Su Jing.

"Okay, Master Liu, let me take a look."

Su Jing nodded and took the spring, and checked it briefly.

In terms of shape, the craftsmanship of these master craftsmen is trustworthy, and they can basically be as good as the drawings.

But the core of the spring is the "bounce" caused by its internal stress.

Unfortunately, it is still not satisfactory.

"I'm sorry, Mr. Su, I'll do it again."

Master Liu just saw Su Jing's expression, and he knew that what he made was not up to standard, and he had to redo it immediately.

"Master Liu, wait."

Su Jing called to Master Liu, took the spring in his hand and said, "It's too difficult to make a spring out of steel, what if it's replaced with copper?"

The texture of copper is much softer than steel, and it is much easier to shape and so on.

Just because it is too soft, the "elasticity" will not be too strong.

But what Su Jing needs now is a stable spring.

"Okay, I'll try it."

Master Liu didn't have any doubts, and immediately turned around to do it.

In the shooting range at this moment, Su Jing is already experimenting with the flintlock gun made by the improved steelmaking method.

Because all the processes have been done before, only the steelmaking method and the mold have undergone slight changes, so this improvement is actually very fast.

However, the appearance of this flintlock firecracker is much lighter than before, no, it should be much lighter than all the firecrackers of Daming.

High-strength steel greatly reduces the thickness of the gun barrel and the thickness of the gunpowder chamber.

Although it is still a flintlock firearm, the overall shape has begun to approach modern firearms.

This is what Su Jing thought firearms should look like.

boom!
There was a gunshot in the shooting range, Mu Ying took off her thick protective clothing, quickly checked the firecracker in her hand, and then ran to the target to observe the hit situation.

Everything is astounding!
This lightweight firecracker is no less powerful than those bulky big guys.

Moreover, the precision is higher.

The reason is simple. Su Jing asked the craftsmen to add spiral rifling when making the barrel mold.

With the blessing of rifling, when bullets, or ammunition such as steel balls fly out, the stability is greatly improved, and the range and accuracy are also greatly improved.

"How about it, it's okay."

Su Jing didn't know when he had appeared in the shooting range, and asked Mu Ying who was testing the gun.

Mu Ying quickly walked in front of Su Jing and said, "Mr. Su, you have improved so much. I never thought that the firecracker can be so light."

Limited by the strength of steel, Daming's firecrackers are very bulky.

Su Jing improved the steelmaking method, which directly increased the strength of the steel by a large amount, thus making the lightweight firecracker possible.

For the generals of the Ming Dynasty who are used to those bulky guys, even if it is only a reduction in weight, it is epoch-making.

"This is just a trivial matter. The development of firearms has two directions. The heavier and heavier it is, the cannon, and the more and more is inevitable."

Su Jing said lightly.

Su Jing was not very interested in the firecracker he had just improved.

The principle has not changed, and the core structure is the same, it just makes the gun body a little thinner.

This is still far away from the real firearms in Su Jing's mind.

"Mr. Su is too modest. With such a firecracker, our Ming army will be invincible in the front line!"

Mu Ying said excitedly.

The size of the firearms troops of the Ming Dynasty is not very large. Firstly, ironmaking is not an easy task in an agricultural country, and the cost is very high.

The other one is the weight of the firearm, which is really exaggerated, and it also needs to be equipped with gunpowder and ammunition.

In this ancient war march, there were not so many options for transportation.

Food and grass are necessary, and other supplies have to be chosen as appropriate.

Therefore, Su Jing's reduction in the weight of the firearms is of great significance to Daming's firearms troops.

Su Jing looked at the excited Muying and said, "Don't just be happy, Brother Wenying, you've finished testing the gun, you can't just say yes, you have to talk about the shortcomings of this thing."

From Su Jing's point of view, there are still many problems with the gun that he improved.

But that is from the perspective of looking at modern firearms in the previous life. For the generals of the Ming Dynasty, this may not be the case.

Mu Ying is a young general with extraordinary knowledge, so she should be able to see some problems.

Holding the firecracker in her hand, Mu Ying said after a little thought: "Mr. Su, I feel that the range and accuracy of this firecracker have improved a lot, but after the ammunition flew out, the damage it caused didn't seem to be as great as before. .”

Lethality, or lethality area, is what Mu Ying needs for firecrackers in actual combat.

Hearing this, Su Jing nodded and said: "Brother Wenying, the range accuracy and lethal power are contradictory, because the more concentrated the ammunition is fired, the longer it can fly and the more accurate it can be shot, while the scattered ammunition If it is opened, it will naturally hit closer, but the same lethality will also increase."

"The balance among them, I have never led troops to fight, so I am not very clear about the balance between distance and power. Brother Wenying may give me some suggestions, and I can improve based on your suggestions."

Su Jing didn't directly veto Mu Ying's suggestion, even though his purpose of improving the firecracker was to increase the shooting range and improve the accuracy.

It is normal for the actual demand to be different from his pursuit.

"Is it okay? Mr. Su?"

Mu Ying was a little surprised.

Su Jing smiled and said: "Of course it can, isn't it a kind of firecracker itself? You can pursue close-range killing, and let the elixir disperse directly when it flies out. This kind of killing distance is very close, but it is hardly hit. Possibly crooked."

"At the same time, you can also chase the ultimate range, and then match the telescope I made on the body, you can achieve the effect of piercing the Yang with a hundred steps, and the army can take the head of the enemy general from it. These can be done with one firecracker, but it can be turned into several Just plant a firearm."

Shotguns and sniper rifles.

One for close range and one for long range.

Su Jing doesn't have any preference for the two, they are both very gun-like weapons.

To Su Jing, this was just common sense, but to Mu Ying, it was extremely shocking.

Fire gun, can there be such a division?

"Mr. Su, Wenying doesn't understand very well, but can you make all the firecrackers you mentioned and show me?"

Mu Ying said to Su Jing.

Whether it is a shotgun or a sniper rifle, Mu Ying wants to see what the actual firearms look like.

If it is really as what Su Jing said, then the functions of these firearms will be improved a lot.

"of course can."

Su Jing said with a smile: "There are so many craftsmen here, this matter is still very simple."

Although Daming's level of science and technology is so high, Baoyuan Bureau has gathered the most powerful craftsmen of Ming Dynasty. Su Jing is still confident in completing this level of modification.

"Then trouble Mr. Su!"

Mu Ying immediately bowed to Su Jing, if he wasn't still wearing the test suit pants, he would probably kneel down.

"What's the trouble here? I'm here to make guns. If you like what I want, don't worry about it."

Su Jing said with a smile.

It was really a surprise to come to Baoyuan Bureau.

Here, no one who bothered me appeared.

Probably Zhu Yuanzhang explicitly prohibited them from appearing, and making guns was the top priority.

It is Su Jing's interest to make guns. The personnel and materials are all ready, and he can command and use them at will, and no one has interfered.

Such a good thing is really cool.

Not even Zhu Yuanzhang himself has been here!

"Mr. Su, I'll be leaving first. If you need anything, just ask."

After testing the gun, Mu Ying wanted to report to Zhu Yuanzhang, and Mu Ying wanted to tell Zhu Yuanzhang about the various firecrackers that Su Jing mentioned.

"Okay, let's go."

Su Jing nodded, he didn't have time to chat with Mu Ying here all the time.

……

Qin Wangfu.

Zhu Xi's business finally ushered in Waterloo.

"King Qin, a soap company suddenly appeared on the market, which is almost the same as ours, but the price is only half of ours. Now our business has been basically taken away by him, and those who still buy soap from us are basically Give King Qin your face."

The housekeeper reported to Zhu Xihui.

Consumers are very real, Zhu Xi's soap is expensive, but it has its own uniqueness, so they don't care about the price.

But once you have the same product, the price is lower.

Even if they are rich, it is normal to choose low-priced ones.

And there are still some customers who are still buying from Zhu Yu, but it is because Zhu Yu, the second prince, has the status of King Qin.

It's just that these people are destined not to have too many.

The housekeeper's face was ugly. If this continues, the soap market will be squeezed out.

Zhu Xi's expression was a little nervous, but he didn't panic: "It's okay, continue to produce, if you can't sell it, you'll keep it, anyway, the soap won't spoil."
