Chapter 1087: Heavy Artillery Is Hard to Come by, so Change One

"Bring the system to Datang ()"

Li Yi was relieved about Xiaoqin's matter, and turned to the problem of making cannons.

Cannons can be made, but how to make cannonballs? The range of more than ten miles is not possible.

Cannons need to be transported after they are made, and a cannon is very heavy.

"What kind of cannon can be made that is easy to make and easy to make cannonballs? And can fly far?"

Li Yi muttered and looked up information to see what kind of cannon is suitable for current technology.

After a round of searching, he found that either it was made very large, and then he slowly made the fuse, and then the craftsmen worked hard to manually process the cannonballs.

Including other gunpowder, ordinary black gunpowder can't launch the cannonballs that far.

Adding sealing, how many guns can be made after the whole set?

Li Yi lowered his head and strolled to the workshop, wanting to ask the craftsmen.

He boasted, how to do it is a problem.

"Lao Zhang, how can you make the explosive fly farther." Li Yi walked to the place where bullets were made, where he was responsible for assembling bullets.

Lao Zhang's name is Zhang Guan, and Zhang Guan is resting at the door.

The people who make gunpowder and assemble them change places every day to let the dust that may have been in the room fall down, and open the door to let in air.

Zhang Guan thought the owner was testing him, and smiled: "Simple, isn't the rocket mounted on the car? Put it in a tube, the tube is longer, like the tube of fireworks.

The better the seal, the farther it will fly, but the tube must be strong, and it is best to have a rifling, and use a little lead on the rocket.

Add propellant, and launch the rocket like a bullet. If it is a second-level one like the fire dragon coming out of the water, it is estimated that it can be fired five or six miles away."

"A mortar that can fly a distance by itself?" A picture appeared in Li Yi's mind.

Add a primer to the rocket, the tube is like a gun barrel, and lead and cork are used in the back position to shoot the rocket out at once.

The rocket rotates and flies like a bullet, and is ignited during the flight. After the second-level ignition, it can fly very far.

Is this an extended-range rocket?

After the primer is fired, the rocket flies a certain distance and is ignited by the slow fuse, spraying fire and flying. When it flies to a certain distance, it glides in the air by inertia and then ignites again.

The disadvantage is that it can hold less explosives, and the barrel needs to be cleaned. At the same time, the slow burning of the fuse is a problem.

When firing, a small control is needed to ignite the fuse inside the rocket. With a bang, the pressure in the barrel is high, and it may directly hit all the places where the slow fuse is.

As soon as it leaves the muzzle, the rocket sprays fire.

"No, it's too difficult to manufacture." Li Yi shook his head and denied it.

"Lengthen the rocket and put it in the barrel. It can at least hit four miles." Zhang Guan thought about it and felt that the owner was right. The process requirements were too high, so he changed it.

"Okay, make a barrel, use iron, and try to control the weight of a barrel within 50 kilograms. It can be disassembled and assembled. I will go back to draw a picture."

Li Yi decided to make a barrel for the rocket launcher and use it to launch the long rocket.

He thought of the barrel of his domestically produced 107mm rocket launcher at that time, which was very light, and the shells were also light and easy to operate.

Even so, he could not make this kind of rocket, and could only launch the rocket.

The barrel that can be disassembled should not be too heavy, and the kind that people can carry and walk is good.

One horse can carry two, one on the left and one on the right.

He returned to the study, drew the blueprint in half an hour, and went to Li Longji first.

"Third brother, see if this works. The distance is closer, four miles, and the place where the Yellow River is not wide can be hit."

Li Yi blushed a little when he said it. He had exaggerated before. Unless he exchanged it directly, he would not be able to make a shell that can hit ten miles in a month.

"Ten miles is not possible?" Li Longji was still thinking about it.

"Too heavy, a few thousand pounds, not as good as the rocket." Li Yi told the truth, isn't it just a cannon, grit his teeth, make it specially, it's okay.

How to use it after it is made? A few thousand pounds of stuff can only be pulled by a carriage, and the road is not easy to walk on.

Since we have the technology to make artillery shells, it is better to make copper bullets with primers, so that we can make machine guns.

Li Longji thought about a big iron cylinder, which was transported by a group of people, and frowned: "Is there anything else?"

"I need to make better gunpowder, mortar, powerful, light, and long range."

Li Yi knew that there was something good, but the technical difficulty was high.

Li Longji understood: "Too powerful ones can't be used. Can the sky rocket be shot farther with a tube?"

"Accuracy can also be improved. The manufacturing process of the sky rocket has been improving. Every sky rocket is almost the same." Li Yi scratched his head.

"How are the firecrackers on the village made? Add them in and put them behind the sky rocket." Li Longji gave an idea.

"The cylinder needs to be thickened, estimated to be more than 200 kilograms, and the sky rocket is big." Li Yi calculated the explosion pressure of the firecrackers.

"You make some small and thin ones, with two firecrackers at the back, add a section of sky rocket, and put the arrow tip in front of the sky rocket, for example, it can hit a mile."

Li Longji still has ideas, who said that you have to explode when you hit someone?

A bunch of small tubes are equivalent to long-range arrows. At a distance of 200 steps, they are fired densely. What enemy can withstand it?

If there is still some gunpowder left to explode, the arrows will enter the body and explode again. Even if a firecracker is attached to the body and explodes, can it hurt?

"Good idea, Third Brother is awesome." Li Yi gave a thumbs up.

He thought about it and felt that if the flying monkey with arrows can explode without flying too far, the biggest effect of UU reading www.uukanshu.net is psychological pressure.

Being shot by such arrows is already very uncomfortable, and you have to endure the bang again. Can the battle continue?

"I'll go draw the diagram and do some calculations." Li Yi turned around and gave the diagram to Ziyu, who was standing closest, and he ran back to the study.

Ziyu shook the stack of papers in her hand at Qingsong, smiled, and looked up at the sky.

Qingsong took two steps forward, snatched the diagram from Ziyu's hand, and ran away.

Ziyu: "..."

"The owner gave it to me, and asked me to deliver it, right? You all saw it." Ziyu looked at the others.

Everyone shook their heads together, meaning that you should stop talking. The owner gave you the thing, but you asked others to take it away. What are the consequences of the person who delivered the information being robbed?

"Your Majesty, they all bullied me." Ziyu said to Li Longji.

"Otherwise, let's change Ziyu next time, and I will protect you." Li Longji said lightly.

"Your Majesty, I was wrong." Ziyu almost knelt down and wanted to remove herself from the list. She couldn't live anymore.

Being kicked out of the eight-person group means that Li Dongzhu is unhappy. In this case, everyone can bully her.

What Li Yi drew was what the Song Dynasty already had, rockets, sky rockets with arrows tied to them, but that didn't explode, it just increased the range.

Of course, even with rockets, the Song Dynasty still couldn't defeat the enemy, and they destroyed one after another, and finally the Great Song Dynasty became the Northern Song Dynasty.

Then the name of the Southern Song Dynasty appeared, and the history of the dynasties appeared.

The technology for making weapons was good, but it couldn't resist the strong trunk and weak branches and the emphasis on culture over military.

"Okay, this is it, don't tie it, just insert it in front, add a bamboo cover to control the balance during flight and divert the air. It's called a fairing."

Li Yi also drew the blueprint of the rocket.
