Bright Sword: Starting from the Improved Grenade

Because they were going to build a bullet factory, Zhao Tianyang had breakfast early the next morning and sat in the driver's seat of the 15-horsepower tractor.

He was going to Dongyadi Town to ask the deputy director of the political department for someone.

How can a bullet factory be run without workers?

"Why are you here again?"

The deputy director of the political department had a bad feeling the first time he saw Zhao Tianyang.

"What you said, Chief, can't I come?"

Zhao Tianyang said dissatisfiedly.

"If you can come, why can't you come!"

The deputy director of the political department smiled and poured Zhao Tianyang a cup of water.

"If you come to me to talk or chat, I welcome you, but if you come to me to ask for someone, I'm sorry, I can't do anything for you."

"Ah this..."

Zhao Tianyang hesitated for a moment, then spread his hands and said, "Okay, if there's no such thing, then there's no such thing!"

"I was originally thinking about building a bullet factory as soon as possible to produce more bullets so that the soldiers can get rid of the title of "Three Guns and Eighth Route Army"."

Zhao Tianyang stood up and walked out, sighing, "It seems there is no other way. Since there are not enough people, I can only do it slowly!"

"What! Bullet Factory?"

The deputy director of the Political Department stood up quickly and grabbed Zhao Tianyang: "Look at you, why are you always so anxious? Come and sit down first, I will talk to you slowly!"

The deputy director of the political department sat back in his seat, organized his words and said, "You also know that many people know the location of the arsenal."

"But the workers who enter the arsenal are carefully selected by us, and we try our best to ensure the purity of the workers, so the recruitment of workers has always been a little slow."

"This is the truth."

Zhao Tianyang nodded in agreement: "But if our arsenal wants to develop, we must have sufficient manpower. Without people, I can't even build a factory, so how can I develop it?"

After saying that, Zhao Tianyang thought for a while and suggested: "Since it is difficult to recruit workers, why not let the soldiers in the army transfer to work in the arsenal?"

"Anyway, the army has a lot of people, just give me some people, and it will be enough for my arsenal."

"this......."

The deputy director of the Political Department thought for a moment and said, "That's not impossible."

"But if you want to snatch people from those arrogant soldiers and prevent them from having any resistance, you have to pay something!"

"I?"

Zhao Tianyang asked doubtfully: "What can I give?"

"It's like this. The troops below have been saying that they hope to have a direct-fire artillery. As long as you solve this problem, it will be much easier to get people."

The deputy director of the Political Department explained with a smile.

"Direct-fire artillery? Don't we have the Taihang 70-caliber cannon?"

"Although that thing is not as good as the Japanese Type 92 infantry gun, it is not much worse!"

Zhao Tianyang asked puzzledly.

"You have the nerve to say that!"

The deputy director of the political department rolled his eyes and said, "Only your arsenal can make that thing. Can other factories make it?"

"So far, only the 129th Division has six guns, and the other troops can only watch."

"Hey, that thing is a bit difficult!"

Zhao Tianyang smiled awkwardly: "Okay, I'll go back and think of a way to make them a cheap, simple and efficient direct-fire cannon!"

"Row."

The deputy director of the political department nodded and said, "It would be best to develop a rifle grenade to supplement the close combat firepower of the infantry."

"no problem!"

Zhao Tianyang agreed readily.

............

"The factory manager is back, and lunch is ready. Let's go eat together!"

Huangya Cave, Li Yuncai greeted Zhao Tianyang who had hurried back.

"There's no time. Go get me lunch."

After saying that, Zhao Tianyang ran back to the tent, took out paper and pen and began to design grenade launchers and direct-fire artillery.

"What's the matter? Why are you in such a hurry?"

Li Yuncai looked at Zhao Tianyang who was walking away, shook his head, and walked towards the cafeteria.

The rifle grenade is a point-injury weapon used by infantry at close range.

Mainly used to kill living targets, destroy various light armored targets, permanent fire points and other field fortifications

In order to allow any arsenal below to produce it.

Zhao Tianyang decided to use pure iron or rail steel to make the grenade launcher, and cast iron to make the shells.

After deciding on the materials, Zhao Tianyang began to draw the grenade launcher diagram.

In his vision, the arsenal below could first make a short iron rod.

Then hollow out the iron rod to make a grenade tube, and finally put it on the muzzle of the gun like a bayonet.

If that doesn't work, you can forge iron sheets into a tube.

This rifle grenade has a simple structure and is easy to manufacture.

As for the artillery shells, they are still designed to look like mortar shells, and are fired using bullets without the warheads.

Soon, a design drawing of a grenade launcher took shape based on Zhao Tianyang's calculations.

"The section chief is having dinner!"

At this time Li Yun came in with a big bowl of corn paste and three steamed buns.

Hearing this, Zhao Tianyang put down his pen, took the bowl, took two sips, and then instructed Li Yuncai.

"Send this rifle grenade blueprint to Comrade Shen Hong and ask him to make one according to the blueprint."

"Oh!"

Li Yuncai nodded, took the blueprint and walked out.

Zhao Tianyang took out another piece of white paper and while eating, he was thinking about what kind of direct-fire artillery would have a simple structure and be easy to manufacture.

He first thought of the recoilless rifle, but gave up after thinking about it.

Although that thing has low chamber pressure and low requirements for steel, its direct firing distance is limited, usually only 400 to 700 meters.

Moreover, when it is fired, it will spray flames backwards, which can not only easily injure people, but also expose the target.

Thinking of this, Zhao Tianyang turned his attention to the Taihang 70 cannon. He decided to reduce the configuration of this cannon and make a small flat-fire cannon.

First, the tool for rifling, this shouldn’t be too difficult.

Zhao Tianyang planned to first make an olive-shaped steel column and carve concave and convex lines on it.

When you need to pull the wire into the barrel, just wedge this steel column into the barrel, so that you can make a smooth and slippery rifling.

The most important material for the barrel is rail steel. The arsenal below can use a blast furnace to re-refine the rail steel into pig iron or cast iron.

If that doesn't work, you can also ask a blacksmith to heat the rail steel red, then beat it into the shape of an iron rod, and finally use a hammer to hammer a hole in it.

For safety reasons, the caliber of the shells cannot be too large, so let’s first set it to 36 mm.

After a while, Zhao Tianyang stretched lazily while looking at the unfinished drawing in front of him.

"The section chief has eaten."

At this time, Li Yun came in with a bowl of corn paste.

"What time is it?"

Zhao Tianyang took the bowl and asked.

"It's eight o'clock in the evening. I saw that you didn't go to the cafeteria to eat, so I brought it to you."

Li Yuncai explained.

"Okay, got it."

Zhao Tianyang finished the corn paste in a few bites, handed the bowl to Li Yuncai, and then returned to his desk to complete the drawings of the flat-fire cannon.
