Starting from the bright sword to engage in military industry

Chapter 157 Chapter 156, grenade projectile gun?

"Small thing? Is it easy to use? Have you come up with a new weapon?" Ma Quanyou looked carefully at the blueprint given by Hu Changyi.

"Isn't this just the casing of the grenade? Oh, you added prefabricated fragmentation grooves! You need these grooves, and the casing will explode from these grooves when it explodes, and then ...There are more than 300 fragments, right? Hiss..." Ma Quan was a little shocked.

"Well, this is the number of prefabricated fragments of this shell. As for the specific number of fragments after the explosion, we have to experiment to get a rough value! But it doesn't matter, anyway, this explosion, the surrounding enemies can escape Not much!" Hu Changyi said.

"I believe this! It's this shell... 49mm? It's a bit thicker... Oh yes, the thickness has been reduced by adding grooves, and the diameter has to be added... What are these four straight grooves for?" Ma Quanyou read Looking at the four straight grooves on the drawing, he asked.

"Look at the blueprint of the iron pipe. Are there four protruding tendons in the Internal Classic?" Hu Changyi asked.

"Right? Could it be that these two are used together?" Ma Quanyou asked.

"Hahaha...Old Ma, you finally understand, it's not easy!" Hu Changyi laughed happily, and Ma Quan felt a little hairy when he laughed.

"Come here, let me tell you what this is for!" Hu Changyi squatted on the ground, and Ma Quanyou also squatted down.

"This iron pipe, you must finish it. The inner diameter must be smooth, and the four protruding ribs must be closely matched with the grenade casing! Then, aren't the rifling lines of some of our Hanyang-made rifles worn out? The bad ones delivered this time There are some inside the gun, this one is for Hanyang!"

"Look, after the iron pipe is cast, thread the small hole on this side, and thread the corresponding muzzle. Then, screw the casing onto the muzzle."

"How to use it specifically? Just put the shell of the grenade downwards and put it into the sleeve. The cover of the grenade is opened, and the fire ring is pulled out and put on the hook here."

"Then, just put a blank bullet in the chamber and shoot! The principle is to use the thrust of the bullet to give the grenade a forward force, so as to throw the grenade out! If you want to increase the throw distance, you can add a little black powder inside this casing, 5 grams is enough!"

"Now, do you understand what you want to build?" Hu Changyi said while drawing pictures with branches on the ground. At this time, there were already several simple schematic diagrams on the ground.

"Understood, fully understood! Changyi, Changyi, how did your brain grow? Why do you have so many wonderful ideas?" Ma Quanyou looked at Hu Changyi with burning eyes, and his admiration was filled with It's going to be out of control with the water of the Yellow River.

"Calm down, calm down, don't get excited! This thing is still on the drawing board, and we'll have to wait for your old horse to figure out whether it works or not!" Hu Changyi said.Of course, Hu Changyi was not as calm as he appeared on the surface, and he was a little proud and excited in his heart.

After all, this is the information and ideas provided by Yueguang Xiaoxuan in his book friend group (Xiaoxuan himself is pictured above), and he just realized the brain holes of his friends in the group here.

"Hope, I can successfully complete the requirements of this system and go back to the real world. When I go back, I will talk to my brothers in the group... It seems that I can't tell the truth..." Hu Changyi thought and started running the little train...

"Changyi, don't worry, even if my old horse doesn't eat or drink, I will get it out for you as soon as possible! By the way, how far can this grenade be thrown?" asked the old horse.

"It can go up to 90 meters, and it can reach 150 meters at the far end. However, there are restrictions on this, that is, the preparation time for a launch is a little longer, and the accuracy is also a little bit worse. It takes more practice! But this projectile is used The marching team that came to ambush the devils is still very good, and the group charge to deal with the devils is also good!" Hu Changyi said.

"That's it...we don't care much about the war, but it's good to be able to hit the grenade so far! But Changyi, tell me, you use this Hanyang-made rifle to make this, and that gun is still good Use it?" the old man asked.

"It works! Why can't it work? It's an old horse. You have touched the guns. The Hanyang guns in our hands are almost invisible. The bullets fly sideways when they fly out. They don't follow the right path. What are you using your gun for?"

"So, I'm going to do it in one step! Change these broken rifles into bolt-action shotguns, and repack the shell casings made in Hanyang into shotguns by the way! In this way, comrades who use these modified guns Blessed are you."

"Look, a person fires a few empty shells, then a few shotguns, and a few more fragmentation grenades. When fighting, they can throw grenades from a long distance, and they can use shotguns to hit people when they are close, and fight with bayonets. It won't be too much of a disadvantage!"

"Oh, by the way, I also made a triangular army stab out. If you are interested, you can use cast steel to cast some to test the strength. If it is feasible, we will make some in large quantities for the rifles on our troops. All with bayonets!" Hu Changyi said.

"Changyi, you kid...why didn't you open up early...but it's not too late! Give me the blueprint of the triangular thorn, I'll try it, my old horse won't be going to sleep these days!" Ma Quanyou seems to be full of energy, and I don't know where the motivation comes from?
"Okay, old horse, you are busy. I'm going to repair the gun. The apprentices from the division and brigade should arrive, right?" Hu Changyi said goodbye to the old horse, and went to the entrance of the village to look at the mountain road to the north.

"The triangular thorn is a good thing, so long? So thin... In the shape of a goose wing?" Hu Changyi left, and Ma Quanyou picked up the blueprint of the triangular thorn and looked at it.

"Such a length... I have to make sand molds... Well, first make wooden molds... Oh, and grenades..." Ma Quanyou looked at this drawing, and then looked at that drawing. I don't know how to start feeling...

Ignoring where the old horse was entangled, Hu Changyi saw that the apprentices hadn't come, so he simply went to the yard to watch Chunsheng and his brothers work there.But at this time there was a new soldier in the yard, it was Fu Yunpeng.

"Deputy captain, I still don't understand the structure of this machine, look..." Fu Yunpeng saw Hu Changyi, and naturally came up to him, holding a blueprint in his hand.

"Let me see... oh, this one... this one fixes the twist for the rifling of the gun barrel..." Hu Changyi explained to Fu Yunpeng the structure of the parts on the drawings while waiting for the apprentices to arrive.

When the apprentices arrived, it was time for him to start repairing the gun.

As for the Bayi-style horse rifle?Let's talk about it after the gun is repaired...
