Back to Ming Dynasty as Zhu Biao

Chapter 171 The Firearms Problem
Zhu Biao sat in the big tent holding the blasted fragments and thought over and over again. Before attacking Gansu, he gave the blueprint of Frangji to Liu Bowen and the craftsman of the Military Bureau who accompanied the army.

In Ming Dynasty, Frangji and Hongyi cannon were the two main types of firearms that could be used.

Due to the level of manufacturing technology in the Ming Dynasty, the use of Franco cannons used in field battles in history has decreased.

In addition to being bulky, firecrackers have poor shooting accuracy, and only the bulky Hongyi cannon is still usable.

It has a large amount of ammunition, and a dozen can be a large piece when it is set on the city wall, and it does not need to be carried frequently, so it is more suitable for defending the city.

To change the main reason why the Ming Dynasty was good at defending the city but short at field battles in history.

The number of Francophones is larger, and the shooting accuracy of the firecrackers is higher, so that they will not lose to the Manchus in the subsequent field battles.

Zhu Biao was a little nervous, wondering whether the craftsmen of the ordnance bureau accompanying the army could make this Franc machine.

The level of education of these craftsmen with a foundation in firearms is really not very good, which is also a headache for Zhu Biao.

Today, craftsmen, and the vast majority of those who make firearms, are illiterate craftsmen.

There are a few who can read, but have no scientific knowledge at all.

Zhu Biao thought deeply about this issue.

To manufacture a good firearm, you have to face and solve some problems that must be faced.

He was sitting there writing and drawing, and Xu Miaowei didn't bother, she just put down her food and went out immediately.

The food is cold.

hot well.

cold.

Keep it hot.

"Come on." Zhu Biao shouted.

"His Royal Highness." Li Dabangzi came in immediately and said, "Please give orders, Your Highness."

"Go and invite Mr. Liu and General Xu." Zhu Biao ordered.

"Yes. His Royal Highness." Li Dabangzi went to invite him immediately.

After a while, Xu Da and the others rushed to the big tent and said, "His Royal Highness."

"Uncle Xu, Mr. Liu, I have some ideas about firearms, and I want to share with you." Zhu Biao took a stack of papers in his hand and gave them to Xu Da and Liu Bowen.

"This is?" Although Xu Da knew the words above, he didn't understand some things.

"With regard to firearms, the craftsmen of the ordnance bureau accompanying the army should understand some basic rules of gunpowder launch and explosion. Accurately determine the content of nitrate and sulfur in gunpowder.

It is best to have a record, to determine its range according to the amount of gunpowder contained, and to be able to know the effective amount of gunpowder. "

Zhu Biao explained in words that Xu Da and Liu Bowen could understand.

According to the current words, it is necessary to know some chemical principles to make firearms.Without knowing the chemical reaction principle of gunpowder launch and explosion, it is impossible to accurately identify the content of nitrate and sulfur in gunpowder.

There is no data on what range you get with the amount of powder charged, as the quality of powder varies from era to era.

Its effective ingredients cannot be guaranteed. The same amount of gunpowder may not be able to hit far when it is loaded for the first time.The next batch of gunpowder will have the same quantity, but the chamber may explode.

They don't understand the concept of parabolic motion of objects, and they don't know the trajectory of these shells, so they won't have accurate shooting theory.

The so-called hits are all based on their feelings, and most of them are blind.

Metallurgical theory knowledge, do not know the reasonable smelting process.

Xu Da and Liu Bowen half understood and half understood what Zhu Biao said.

It sounds right, but I can't figure it out even after thinking about it.

"Uncle Xu, have you heard of the habits of some swordsmiths? It's very cruel." Zhu Biao asked.

Xu Da shook his head.

"Your Highness, I know something." Liu Bowen stroked his beard and said, "I heard that at the end of the Yuan Dynasty, there was a general of the Yuan Dynasty who fought against the local rebels and was repeatedly defeated. Even his Mongolian sword was taken away by the rebels. .

He went to find a knife maker, and someone suggested to the general that he could forge a good knife by offering sacrifices to beautiful women.

Some old blacksmiths used the beauties snatched by the Yuan people and threw them into the furnace to make good steel and make swords. "

After Liu Bowen finished speaking, he looked at Zhu Biao.

"Absurd, too absurd." Xu Da got up and shook his head, "Whose girl is redundant, so cruel."

"These things are harmful." Zhu Biao shook his head.

It is precisely because of this backward tradition that even if good iron is smelted, the strength of some iron cannot be guaranteed at all.

"Just like a cannon, a cannon of the same thickness may not have a problem this time, but the barrel will explode next time, and the firecracker is the same," Zhu Biao said.

"Your Highness, in order to ensure everything is safe, we can use copper." Liu Bowen said.

"That's right, Your Highness, use copper." Xu Da said.

"It's okay to use copper, but this copper can't meet our needs." Zhu Biao said: "These can only be discussed after returning to the court."

Xu Da patted the table and said, "I remembered. A few days ago, when I went to inspect, a craftsman said that the thickness of the iron can be increased to prevent the chamber from exploding."

"No, it will increase the weight." Zhu Biao shook his head.

If you are afraid of bombing, you will continue to increase the thickness. Thickening will cause the weight of the gun to be very heavy. It will not be possible to manufacture a gun like the Francophone, which will reduce the combat capability.

Zhu Biao walked to the table, wrote out what was discussed just now, and handed it to Xu Da.

"Firearms should be made with uniformity in size, shape, weight and surface roughness."

"The firing angle and exit speed of this cannon?" Xu Da pointed to the next item.

"This is like this..." Zhu Biao used his influence to popularize words that they could understand.

"There are also craftsmen who must be trained to guide and use firearms and artillery correctly, and they cannot come based on personal experience or feeling." Zhu Biao reminded.

Xu Da sat next to him and said, "I still remember the Daming Military Academy that His Royal Highness said before the expedition. Now I think it is very necessary."

"Exactly, we have all seen the power of firearms. If we develop them, there will be no resistance." Liu Bowen said: "The power of firearms and cannons, the Five Elements, Eight Diagrams, and Yin-Yang theory are all three points stronger."

"Mr. Liu, you still need to supervise the Ordnance Bureau. In the past few days, let's continue to discuss improvements and make a pamphlet."

"Yes, Your Highness the Crown Prince." Liu Bowen said.

……

The city of Nanjing thousands of miles away.

The sleeping hall is brightly lit.

Old Zhu took a vermilion pen and wrote there a few times before ticking off: "We still think it's inappropriate."

"Yu Yi, you go out first." Empress Ma told the eunuchs and maids to leave the Qianqing Palace before walking up to him.

Seeing what was drawn on it, Empress Ma pointed to it and said, "When you were fighting, I was reading history books there every day. In fact, what Biaoer said was right, our salary is a bit lower."

Old Zhu didn't speak.

Last time, the servant of the household department reminded Lao Zhu that he suggested the issue of salary.

Lao Zhu directly asked someone to drag him out of Fengtian Temple, beat him with more than a dozen sticks, and the blows were so hard that he lay at home and couldn't get out of bed for half a month.

He felt that this group of officials wanted to embezzle.

Tonight, Empress Ma knew that he was going to talk about salary, so she let Yu Yi and the others go out.

In case you hear something you shouldn't hear, your Majesty's donkey temper will come up and beat people again.

"Is it low?" Old Zhu pointed to the numbers that were ticked off.

"Heavy eight, isn't it low? How can you live a good life with such a salary." Empress Ma glanced at him and took the pen: "Biaoer did a small calculation for me before, and I will do the calculation for you."

"What account?" Old Zhu said.

"When the country was founded, one tael of silver bought two stones of rice. This spring, the price of grain has risen..."
