Chapter 166 Conical bullet concept

The principle of the rifling process is very simple. It is nothing more than cutting the inside of the circular gun barrel with a knife back and forth to scrape out the rifling. The difficulty lies in the stability of the rifling machine tool.

If the output of the steam engine is unstable, and when the rifle is pulled, it is suddenly slashed and the rifle is pulled crookedly, then the barrel will become a waste product.

Like those scrap guns, they are either used as low-quality smoothbore guns, or thrown into the converter of the steel factory, where they are used as scrap steel and remelted into liquid steel.

Fortunately, after this period of development, the accessories of the steam engine are relatively complete, including separate condensers, centrifugal governors, etc. The stability of the steam engine has been improved to a higher level, and the basic needs of drawing the rifle are already met.

All of this stems from the various technological memories in his mind. As long as the materials are qualified, resources and manpower are available, he can develop the industrial technology of the territory by leaps and bounds.

Now there are many places in the territory that need steam engines, but there are not many factories that actually have steam engines.

There is one steam engine in the mine, one in the glass factory, and multiple steam engines in steelworks, steelworks, and blacksmith shops. They are basically first-generation steam engines and are easy to make.

This generation of steam engine uses the vacuum generated when the steam condenses to do work. The efficiency is limited, but the advantage is that the pressure is lower and it is safer.

Allen took the time to go to the blacksmith's shop in the morning, and used his full-level teaching ability to explain for 15 minutes, from the shallower to the deeper, from the outside to the inside, to explain the principle of pulling the rifle.

The experienced craftsmen are not stunned a few months ago. They have a strong ability to accept industrial knowledge. After 15 minutes, there will be no doubts. Next, they only need to follow the steps step by step and strictly follow the drawings.

Dangdang, the machine tool manufacturing team in the blacksmith shop began to warm up and fell into the hot machine tool manufacturing.

Since manufacturing machine tools is a very time-consuming task, Allen didn't keep staring at them and turned around to the bullet making working group in the blacksmith shop.

The bullet workshop is very large, with rows of molds containing molten lead solution.

When the lead solution drops to a temperature of one degree and condenses into a solid state, the lead metal is easy to process, and then sent to the furnace to heat the surface until it turns red, and then the two hemispheres are violently pressed together by a powerful machine tool to synthesize a rough embryo of the lead bullet. The round buckshot made by this method has a circle of "equatorial line" with obvious color.

The cat-eared orc who made the bullets was supervising the slave orcs to come back and walk around. When they turned around, they suddenly found a man in formal clothes standing at the door of the workshop, and his heart shivered.

Making bullets is a confidential matter in the blacksmith shop. There are heavy guards at the door. Normal people need to go through layers of guards to check in. There is only one person who can appear at the door quietly, and that is Allen!

"Master Alan, why are you here? Is there a problem with which batch of bullets popped out?" Daisy carefully put away the cat's tail behind him, which was a small gesture when he was afraid of someone.

There are a lot of slave members in the blacksmith shop, and they often use groups, division of labor and cooperation. Every day, someone records the laborers involved in a certain batch of products.

"No problem, Abel started to make machine tools for drawing rifles, so the bullets have to be updated." Allen gave him a reassuring look.

When Daisy heard about the replacement, he wondered, "Aren't the bullets all round? Why do they need to be replaced?"

"When you understand rifle technology, fluid mechanics, you will know why."

After Allen finished speaking, he saw Daisy's stupid stare, and added: "Study physics seriously, this subject is very important to you."

When it came to physics, Dai Xi pretended to be enlightened and said he understood.

Reasonable physics books are like heavenly books. He has a teacher to teach them in class, and he knows a little bit, but he forgets them all after class.

Not everyone has the opportunity to listen to Allen's teaching classes. Allen's full-level teaching objects are mainly for teenagers aged 20 to [-].

Orcs in their 30s and [-]s like Daisy can only enjoy the lessons of other teachers.

Allen mainly teaches teenagers, and the orcs in the town express their understanding. After all, teenagers have a strong ability to accept, while the worldview of adult orcs has been finalized. Even if there is a short-term change, the efficiency is not high enough.

"Then do I need to go back and review my physics textbook?" Daisy asked hesitantly.

"No, you all have a small group of experienced hands over here and set up a miniature bomb production team. I will personally teach you the principles and production process of miniature bombs, but I will only teach you orally. Afterwards, you need to explore by yourself."

Allen turned and walked to the wall of the bullet workshop, where there was a huge blackboard.

"Understood, I'll find someone to set up a new team immediately." Daisy couldn't help but want to jump up and celebrate when he heard that Alan was going to teach people in person.

Daisy still remembers the first time he heard Allen's class on how to make round lead bullets, and he never needed two sentences to explain things clearly in one sentence.

And the corresponding production picture will appear in Daisy's mind, and the picture is lifelike, as if he made the projectile himself.

After going to bed the next day, it was still vivid and hard to forget.

He couldn't help blowing a whistle, and shouted loudly: "Lion cubs, do you want to make new bullets? Master Allen is here, and follow me if you want to do it."

The lions who were making bullets froze for a second, put down their work one after another, and shouted: "I, I, I!"

"Master Daixi, I have had dinner with you, you must choose me!"

"It's great that you have had dinner with Daisy. Master Allen wants familiar hands, and the new ones are shameless!" Some old men who have been working for several months despise the new slaves.

The lion slaves were impatient, and there were even fewer opportunities to listen to Allen's lectures, and they would never let them.

Allen was still indoors, and Daisy trembled all over. He originally planned to choose some people at random, but now he can't just do it casually.

He took a closer look first, and didn't choose those old acquaintances who were farting, but those orcs who usually worked hard. They had been working for a few months, and there were absolutely no newcomers.

Daisy carefully assembled the people, and Alan was not surprised, so he picked up the chalk and started speaking.

"What is smoothbore, what is rifled, and who is more advanced, I will briefly explain here..."

A minute later, Allen sorted out the two gun systems, and the orcs in the audience finally understood why the guns were engraved with rifles.

Allen said again: "The barrel has a rifle, and the rate efficiency is not enough. We also need to make changes to the bullets we make to fit the rifle and improve accuracy..."

"Here is the conical bullet. When the conical bullet flies, the air flow path is like this. Everyone here has studied physics. I don't ask you to learn it. At least you know about air resistance. The conical bullet The design of the head can reduce air resistance..."

Allen drew casually, drew the conical bullet, and drew the air flow path.

After spending 3 minutes, the orcs already had the concept of why the conical bullets are awesome.

Daisy, the cat-eared orc, had already stared wide-eyed, taking notes with both hands, secretly sighing how powerful the design is.

Allen spoke calmly on the stage, and the orcs off the stage were eager to attract new knowledge and open a new door to bullet technology.

Allen explained the next highlight, "In addition to the tapered bullet, the most important thing is to fit the rifling inside the barrel. This is another concept-expandable bullet."
