Starting from the bright sword to engage in military industry

Chapter 124, Chapter 123, Bomb training and production planning

"Everyone memorizes the essentials of the action! Well, come one by one, you, come here, and prepare to drop the bomb!" Zhao Fengnian stood behind a circular sandbag wall by the river, with sandbag partitions on the side, directing a recruit to carry out bomb.

The recruit is said to be a recruit, but he is about 25 or [-] years old. He is not tall, but he is quite strong.

"Remember, unscrew the cover, pierce the waterproof paper, take out the pull ring, and hang it on the root of the little finger of your right hand! I have practiced the throwing posture for so long, so I won't repeat it! Now prepare..." Zhao Fengnian stood majestically in front of the recruits, commanding them to throw grenades.

Then, according to Zhao Fengnian's command, the recruit held the grenade in his right hand, pierced the waterproof oil paper layer, took out the pull ring and fastened it to the root of the little finger of his right hand.Then, take a step back with your right leg, bend your knee, and straighten your right arm...

These recruits were miners and civilians before, and had no experience in throwing grenades, so Hu Changyi taught Zhao Fengnian the most standard way of throwing grenades, and then led these recruits to train them out.

As for why?Hu Changyi didn't think too much about it, anyway, the younger soldiers were trained like this, so just follow suit.Of course, if you don't want to do this, you can also throw it out after pulling the fire, as long as you don't throw it in your own position.

The recruit performed well. After a standard bomb-throwing action, the grenade flew out without throwing it in front of him.

Hu Changyi's side was not far from the river, and it was obvious that the grenade flew out with smoke, and fell silent at a place of more than 30 meters.

"Changyi, is that the grenade you made? How could you be fooled?" Lao Ding, the soldier driving the car, looked at Hu Changyi and asked after watching the whole journey.

"Ahem, don't look at me like that, it's just stupid, there's no explosives at all, it's filled with sand..." Hu Changyi said.

"Ah... that's it!" Lao Ding said.

"That's it. Now it's bombing training. Isn't it a waste to load explosives! Besides, the ignition fuzes used for the training bombs are all products made during the experiment. The quality is hard to say, so I just use them as training bombs!" Hu Changyi Said.

"Then... Changyi, can I think so, these grenades you use for training can be blown up with explosives, right?" Lao Ding looked at Hu Changyi with bright eyes.

"Well, you can also say that! However, because there is no suitable fire detonator, so it can only be filled with black powder, the power of the grenade will be very small! Take a closer look at the shell of the grenade, isn't it particularly big?" Hu Changyi asked.

"It's very big! It's bigger than the Jin-made grenade!" Lao Ding said.

"Big is right! The power of black powder is too small, I can only increase the amount of charge! This can hold three taels of black powder, and after the explosion, the killing radius can reach about 6 meters. Of course, the premise is that there are enough fragments, fragments We have to greet the devil!" Hu Changyi said.

"That's pretty good, it's better than nothing!" Lao Ding said.

"Yeah, it's better than nothing! But now that the superiors have sent so many Kai-style explosives, we can make some imitation Jin-made grenades! When I get the detonator out, we can make powerful Jin-made grenades!" Or use our TNT plus some potassium nitrate to make some fortified grenades!" Hu Changyi said.

"Is there any difference between these two grenades?" Lao Ding asked.

"The difference... is the difference between the charge and the size, length, and weight! But I plan to unify the standards here, one standard for black powder, one standard for high explosives, and try to achieve length, weight, explosive power, explosive The delay time is the same!" Hu Changyi said.

"That's a good relationship! What, Chang Yi, you have to hurry up here, tens of thousands of us are eagerly looking forward to it! It's still the same sentence, even if there is no powerful one, there is a small one! Let's Throw a few before fighting the bayonet, and you won't suffer!" Lao Ding said.

"I understand! I won't let everyone wait too long! As long as I make it here, and determine the process and standards, I will promote this technology and strive for each of our regiments to have its own grenade workshop. Wherever you go, you can build it!" Hu Changyi said.

"Haha, Changyi, don't brag, let's put our things down first, and we're at the right place! Huh..." Lao Ding yelled to stop the carriage.

"Okay, everyone, gather and go over to help move things!" Without Hu Changyi's greeting, Zhao Fengnian rushed over with 32 guerrilla recruits.

"Captain, let me introduce you first! This is Xin Lu, nicknamed Xiao Mao, and he is now a recruit of our guerrilla team! Take him to train with him first, and follow me when I train the grenadier soldiers in the afternoon!" Hu Changyi introduced Xin Xiaomao to Zhao Fengnian.

"Okay! Comrade Xiao Mao is welcome to join our guerrillas!" Zhao Fengnian welcomed Xin Lu.

"Thank you, Captain! Captain, my name is Xin Lu, hard working Xin, Road Road!" Xin Xiaomao really wanted everyone to call him by his name.

"Well, I got it! Your name is Xin Lu, and your nickname is Xin Xiaomao! Everyone will call you Xiaomao from now on, so kind!" Zhao Fengnian said.

"Vice-Captain, Brother...Look at this..." Xin Xiaomao asked Hu Changyi to be his rescuer.

"Well, if you don't want people to call you by your nickname, prove yourself on the battlefield! Say nothing, and when you kill 5 devils, no one will call you by your nickname, because you are already a You are a qualified fighter!" Hu Changyi patted Xin Xiaomao on the shoulder and said.

"Okay! Let's talk about it!" Xin Xiaomao said.After finishing speaking, he stretched out his hand, expressing that he would high-five as an oath.

"It's a deal!" Hu Changyi stretched out his hand and slapped Xin Xiaomao on the face, fulfilling this small oath.

(Devil: What do you take me for? What do you take?)

A ton of explosives was quickly moved into the room used by the guerrillas as a warehouse, and the three of Lao Ding and the others drove the carriage back to the regiment headquarters.

Then, everyone continued to be busy. Hu Changyi took a pencil to draw pictures in his notebook, calculating the data of the new high-explosive grenade.In fact, this is nothing to calculate, the system data is ready-made, but Hu Changyi just unifies the specifications.

The grenade of black powder weighs about 500 grams, which is exactly one catty, the length is controlled at 240mm, and the explosion radius ensures that the fragments can penetrate the human body within 6 meters.As for whether it will explode in two halves or more fragments after the explosion, it depends on the situation.However, the data provided by the system assistance is between 30 and 50 fragments.

The weight of the high-explosive grenade is controlled at about 450 grams, the thickness of the cast iron shell is appropriately thickened, the charge is about 50 grams, and the length is 220mm.

As for the explosive power, if it is replaced with a ratio of 6 to 4 TNT potassium nitrate, the explosion radius can reach 10 to 15 meters. This is the data for consolidating grenades.

As for changing to Kaizi explosives, the power is not much different, the key is to see how the quality of the cast iron shell is?

Now the guerrillas have a ton of Kai explosives, 130 kilograms of TNT explosives, and 700 kilograms of potassium nitrate.However, potassium nitrate needs to be used to make black powder, and the demand is still quite large, which requires continuous boiling of nitrate.

From this point of view, the high-explosive grenades that the guerrillas can make this time are much more than the low-explosive grenades of black powder, if only calculated from the raw materials.This is the advantage of having raw materials for finished products, that is, when the finished products are always used up.

Therefore, Hu Changyi had to quickly get the data of the new high-explosive grenade, and then let someone produce it.When the fire detonator is produced, grenades can be produced in large quantities.

As for the grenade, as long as the raw materials are ready, it will be made much faster.
