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 she was going to make next.
Simply making a flintlock style fire gun would be a repudiation of these master craftsmen.
Therefore, Su Jing thought of a gun, a very crude gun in her previous life: the FP-45 Liberator pistol.
This is a firearm with such a simple structure that Su Jing in her previous life could find the structure diagram just by searching on the Internet.
Not only that, some toy factories have also made assembly toys of the FP-45 Liberator pistol.
For a firearm to be in such a situation, it can only mean one thing, that is, its structure is really simple.
All parts added up, there are only 23 in total.
This is a pistol developed during World War II. It has 23 parts, including all spring jams and other parts.
Assembling this gun takes only 6 seconds for a skilled worker.
Of course, because of its simple structure, its shooting accuracy and killing range are quite limited.
The FP-45 Liberator pistol was not invented for large-scale combat, but as a means of quickly arming civilians.
This firearm was quickly destroyed after its historical significance ended.
But now, it is Su Jing's best choice.
Because the scientific and technological level of the Ming Dynasty was not even slightly different from that of Su Jing's previous life.
Su Jing was still a little unsure about making the FP-45 Liberator pistol.
But this is what Su Jing can think of. Given the Ming's technological level, it is the most likely modern firearm to be created.
Su Jing soon encountered the first problem.
It is basically a component found in all modern firearms.
spring!
Su Jing didn't know how to make the spring, so she could only tell the craftsmen the shape and characteristics of the spring, and then 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 an empty shape but no internal stress.
Therefore, springs can only be forged by craftsmen's hands.
A spring is also needed in a flintlock gun, but Su Jing used a clockwork spring instead, but the FP-45 Liberator pistol requires a spiral spring.
At this time, the problem arises again. Regardless of whether the forged spring is uniform and detailed enough, it is very difficult to just produce spring steel.
If you want to make a spring, you definitely cannot use ordinary steel.
Spring uses its elastic deformation to absorb and release external force, so the spring steel is required to have a high elastic limit, good resistance to elasticity loss, and a high yield-strength 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 plastic toughness are alloying elements and heat treatment.
In addition, there are materials, which require high metallurgical quality and structural 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 sources of crack fatigue, thus making Reduced fatigue strength…
These things were the most basic in Su Jing's previous life.
But for the current Ming Dynasty, they are all the most advanced and cutting-edge technologies, even technologies that have not yet appeared.
Su Jing is really in trouble now. She didn't expect that a gun with the simplest structure in the previous life would be so difficult to make in the Ming Dynasty.
industrialization!
Industrialization is needed to make these things easier.
But industrialization was too difficult for the Ming Dynasty, which was a predominantly agricultural society.
At least, there needs to be an industrial revolution.
Just thinking about it, Su Jing felt it was impossible. The shortcomings of the feudal unified dynasty were also highlighted at this time.
The emperors ruled the world, and what they wanted most was not scientific progress, but maintaining their own rule.
Although the West also has rulers, in a divided state, it is difficult to unify ideas, and it is easy for ideas that are difficult to unify to burst out different things.
This is not to belittle oneself, it is just a fact.
"Mr. Su, can you take a look at the spring I made?"
Another craftsman came to Su Jing and handed the newly forged spring into Su Jing's hand.
"Okay, Master Liu, let me take a look."
Su Jing nodded, took the spring, and checked it briefly.
In terms of shape, the craftsmanship of these master craftsmen is trustworthy, and they can basically make it very similar to the drawings.
But the core of a spring is the "elasticity" caused by its internal stress.
Unfortunately, it's still not satisfactory.
"I'm sorry, Mr. Su, I'll do it again."
Master Liu just saw Su Jing's expression and knew that what he made was not up to standard and he had to redo it immediately.
"Master Liu, wait."
Su Jing called out to Master Liu, held the spring in her hand and said, "It is too difficult to make a spring from steel. What if it is replaced with copper?"
Copper is much softer than steel, and it is much easier to shape.
Just because it is too soft, the "elasticity" is not 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 was already experimenting with the flint-fire musket made using an improved steel-making method.
Because all the processes have been done before, only the steelmaking method and the mold have changed slightly, so this improvement is actually very fast.
However, this flintlock-style fire gun looks much lighter than before, no, it should be much lighter than all the fire guns of the Ming Dynasty.
High-strength steel greatly reduces the thickness of the gun barrel and the thickness of the powder chamber.
Although it is still a flintlock-style musket, the overall shape has begun to approach modern firearms.
This is what Su Jing thinks firearms should look like.
boom!
There was a gunshot in the shooting range. Mu Ying took off her thick protective clothing, quickly checked the gun in her hand, and then ran to the target to observe the hit situation.
Everything is shocking!
This lightweight fire gun is no less powerful than those bulky big guys.
Moreover, the accuracy 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 improved a lot.
"How about it, it's okay."
Su Jing didn't know when she had appeared in the shooting range and asked Mu Ying who was testing the gun.
Mu Ying quickly walked up to Su Jing and said: "Mr. Su, your changes are so amazing. I never thought that the fire gun could be so light."
Limited by the strength of steel, Daming's firecrackers are very heavy.
Su Jing improved the steel-making method, which directly increased the strength of steel by a large margin, making lightweight fire guns possible.
For the Ming generals who were accustomed to those bulky guys, even if it was just a reduction in weight, it would be epoch-making.
"This is just a trivial matter. The development of firearms is inevitable in two directions. Getting heavier and heavier means cannons, and getting heavier and heavier is inevitable."
Su Jing said lightly.
Su Jing was not very interested in the fire gun she had just improved.
The principle has not changed, and the core structure is the same, but the gun body has become lighter and thinner.
This is still far away from the real firearms in Su Jing's mind.
"Mr. Su is so humble. With such a blunderbuss, our Ming army will be able to do anything on the front line!"
Mu Ying said excitedly.
The size of the Ming Dynasty's firearms force was not very large. First of all, iron smelting was not an easy task in an agricultural country. The cost was very high.
Another thing is that the weight of the firearm is really exaggerated, and it also needs to be equipped with gunpowder and ammunition.
In ancient times, when fighting and marching, there were not so many transportation options.
Food and grass are necessary, and other baggage must be selected as appropriate.
Therefore, Su Jing's reduction in the weight of the gun was of great significance to the Ming Dynasty's firearms troops.
Su Jing looked at the excited Mu Ying and said, "Don't just be happy, brother Wenying, you have finished testing the gun, but you can't just say yes, you also have to talk about the shortcomings of this thing."
In Su Jing's opinion, the firecracker he had improved still had many problems.
But that was from the perspective of looking at modern firearms in previous lives. For the military generals of the Ming Dynasty, this was not necessarily the case.
Mu Ying is a young general with extraordinary knowledge and should be able to see some problems.
Mu Ying held the fire gun in her hand, thought for a while and said: "Mr. Su, I feel that the range and accuracy of this fire gun have been improved a lot, but after the ammunition flies out, the damage caused is not as great as before. .”
Lethality, or killing area, is Mu Ying's need for fire guns in actual combat.
Su Jing heard this, nodded and said: "Brother Wenying, range accuracy and killing power are contradictory, because the more concentrated the ammunition is fired, the longer it can fly farther and hit more accurately, while the ammunition is scattered. If it is opened, it will naturally hit closer, but the lethality will also increase."
"I have never led troops to fight in this balance. I am not very clear about the balance between distance and power. Brother Wenying may be able to give me some suggestions. I can make improvements based on your suggestions."
Su Jing did not directly reject Mu Ying's suggestion, even though his purpose of improving the fire gun was to increase the range and improve accuracy.
It is normal for the actual needs to be different from his pursuit.
"Is this still okay? Mr. Su?"
Mu Ying said with some surprise.
Su Jing smiled and said: "Of course, the fire gun itself is a kind of thing. You can pursue close-range killing and let the elixir scatter directly when it flies out. This kind of killing distance is very close, but there is almost no impact. It may be crooked.”
"At the same time, you can also pursue the ultimate shooting range, and then use the telescope I made on your body to achieve the effect of piercing the Yangtze with a hundred steps and taking the enemy general's head from it. This can be done with a fire gun, but it can be turned into several Just plant a firecracker."
Shotguns and sniper rifles.
One kills at close range and the other kills at long range.
Su Jing has no preference between the two. They are both weapons with the characteristics of firearms.
This was just common sense to Su Jing, but to Mu Ying, it was extremely shocking.
Can fire guns be divided like this?
"Mr. Su, I don't know much about Wenying, but can you make all these firecrackers you mentioned and show them to me?"
Mu Ying said to Su Jing.
Whether it's a shotgun or a sniper rifle, Mu Ying wants to see what the actual firearm looks like.
If it is true as Su Jing said, then the effectiveness of these firearms will be greatly improved.
"sure."
Su Jing smiled and said: "There are so many craftsmen here, this matter is still very simple."
Although the level of science and technology in the Ming Dynasty was only so high, Baoyuan Bureau gathered the most powerful craftsmen in the Ming Dynasty. Su Jing was still confident that this level of modification could be completed.
"Then I'll trouble Mr. Su!"
Mu Ying immediately bowed to Su Jing. If he hadn't been wearing a lab coat and pants, he would probably have knelt down at this moment.
"What's the trouble? I'm here just to make guns. It's something you and I agree on, no trouble at all."
Su Jing said with a smile.
Coming to this Baoyuan Bureau is really an unexpected surprise.
Here, no one bothers me.
It was probably because Zhu Yuanzhang had explicitly prohibited them from showing up, so making guns was the top priority.
Making guns is Su Jing's hobby. The personnel and materials are all ready, and she can direct and use them at will, and no one has interfered.
Such a good thing is really great.
Even Zhu Yuanzhang himself has never been here!
"Mr. Su, I'll leave first. If you have any needs, just ask."
After testing the gun, Mu Ying wanted to report to Zhu Yuanzhang, as well as the various firecrackers Su Jing mentioned, Mu Ying wanted to inform Zhu Yuanzhang.
"Okay, let's go."
Su Jing nodded. He didn't have time to talk nonsense with Mu Ying here.
…
Prince Qin's Mansion.
Zhu Xi's business finally faced Waterloo.
"King Qin, a soap suddenly appeared on the market. It is almost the same as ours, but the price is only half of ours. Now our business has been basically snatched away by him. Most of the people who are still buying soap from us now are Give King Qin your face."
The housekeeper reported to Zhu Xihui.
Consumers are very real. Zhuxiang's soap is expensive, but it has its own uniqueness, so they don't care about the price.
But once the same product is available, the price is lower.
Even if they have money, it is normal to choose low-priced ones.
There are still some customers who are still buying from Zhu Chong, just because of Zhu Chong, the second prince, and the status of King Qin.
However, these people are destined to not be too many.
The butler's face looked ugly. If this continues, the soap market will be crowded out.
Zhu Xiang looked a little nervous, but he didn't panic: "It's okay, continue production. If you can't sell it, just keep it. The soap won't go bad anyway."
