Shi Xin entered and saluted.

Zhu Jianji smiled: "I just asked you to upgrade the Dongfeng sniper rifle the day before yesterday, and it will produce results so quickly?" ”

The principle of the bowstring used for the firing pin of the current Dongfeng sniper rifle, the material is the string, and it is not used many times. Moreover, the quality of the hand-engraved rifling is too poor, resulting in a short range of accurate shooting, which can only be regarded as a strengthened version of the firearm, which is a little worse than the serious Mine rifle.

Moreover, the barrel is limited by the steelmaking process, and the accurate range is reduced after three shots.

Eight guns were scrapped directly.

Shi Xin smiled: "No, the problem of the firing pin and the barrel is easy to solve, after all, the firing pin can be replaced as long as there is a bullet yellow, and the barrel is a steelmaking process problem, which has been solved, but the principle of automatic cartridge withdrawal proposed by His Royal Highness, Weichen has a doubt." ”

Zhu Jianji was a little embarrassed, "Let's talk about it." ”

He also doesn't understand guns.

Therefore, the principle of retracting the shell, racking his brains for several days, thought that it should be the principle of bullet yellow and leverage, as for the specific layout, let Shi Xin have a headache.

As a result, Shi Xin gave him the problem again.

Shi Xin said: "In fact, the principle of automatic cartridge withdrawal mentioned by His Highness is very simple, directly add a bullet yellow under the tail of the bullet, after the bullet is loaded, the bullet tail suppresses the bullet yellow, and the bullet body is stuck in the barrel." ”

"But there is a problem with this, the body of the bullet is basically pressed against the barrel, which directly leads to the reduction of the range of the bullet, and there is a lot of friction between the bullet and the barrel, and the barrel is easy to break, so this principle is not feasible."

Zhu was overjoyed, and sure enough, he specialized in the art industry.

"So what solution do you have?" ”

Shi Xin said: "In the test, I found a phenomenon, that is, the moment the bullet is fired, there will be an invisible force, so I was thinking, you can separate the barrel and the barrel, when shooting, the body and the barrel will jam the bullet, after the bullet is detonated, use this invisible force to separate the gun body and the barrel to expose the gap, and at the same time drive the connecting rod to push out the bullet case." ”

Zhu Jianji was stunned.

This......

Seems a bit like the pneumatic unloading device of modern firearms?

Get excited, "Can you make it?" ”

Shi Xin said: "There is hope, but it may take a year and a half." ”

Zhu Jianji smiled: "Then do it." ”

Shi Xin coughed.

Zhu Jianji understood, "It's okay, I'll ask Dai Yi to allocate funds to the ordnance supervisor." ”

Shi Xin smiled: "As long as there is a principle design, the rest of the matter will be handed over to the money, Your Highness rest assured, as long as the money is in place, Weichen is confident that this problem can be solved within half a year, and this design can also be used on the rifle, so——"

Zhu Jianji came to his senses, "Mass production of rifles, postponed?" ”

Shi Xin said: "That's exactly what it means, and Weichen still has some ideas." ”

Zhu Jianji smiled: "You say." ”

Talent!

It seems that it is not that Daming has no talents, but that it is limited by the times.

Now that I have a principle, I can trigger Shi Xin to think of part of the principle of modern firearms, and there are many, many people like Shi Xin in Daming, my sons and daughters of Shenzhou, there is never a shortage of talents!

Shi Xin said: "On the design of His Highness's 'Desert Eagle', there is a magazine, which makes Wei Chen very inspired, why don't we design a magazine for the rifle as well?" ”

The principle of the magazine is simple.

Zhu Jianji shook his head, "You can have this idea, Lone is very pleased, but the rifle does not need a magazine, because the range of the rifle is not far away, and accuracy is required. ”

got up, walked to the bookshelf behind him, picked up a piece of rice paper, and handed it to Shi Xin.

"This design drawing, Lone didn't give it to you with the 'Desert Eagle', because I think it is a bit beyond our current technology and craftsmanship level, and I think that the road should be taken step by step, first get the rifle and the 'Desert Eagle', and then get this, since you think of it, Lone will show you."

Shi Xin looked at it for a while, "This is a small artillery?" ”

There are also wheels.

There are also cannon barrels, and the barrels are very dense circles, does it mean that they have to rotate and shoot?

And it is also a few bodies smaller than artillery.

Zhu Jianji shook his head, "It's not artillery, let's think it's a rapid-fire rifle, it doesn't require accuracy, but intensive fire suppression, so this thing needs a magazine." ”

"The Legend of the Fairy Tree"

Shi Xin's eyes lit up a little, "What's the range?" ”

Zhu Jianji said: "This kind of firearm, Lone calls it a heavy machine gun, referred to as a heavy machine gun, in Lone's view, as long as its range is less than 1,000 steps, and the accurate range is less than 500 steps, it is a failed product." ”

Shi Xin gasped.

The range is 1,000 steps, and the accuracy range is 500 steps?!

What does that mean?

It means that the enemy was shot and killed before he saw what our sergeant looked like.

And the rifle developed by His Royal Highness asked the Ordnance Superintendent to have a range of 350 paces.

If an army is equipped with more than a dozen rapid-fire guns of this kind, plus a few thousand rifles, as long as there are enough bullets, it can basically wipe out the enemy in less than a hundred steps.

This is a heavy weapon for the town and country in the subversive era!

Zhu Jianji said with a smile: "Of course, our current level of craftsmanship may be a little difficult to achieve, you take this design drawing, carefully consider how to develop it, in addition, the idea of adding a magazine to the rifle you said, I also think it is feasible, the principle remains the same, but the overall weight of the rifle should be aggravated, and the process of the barrel should also be improved, because rapid fire has higher requirements for the barrel, otherwise the barrel will be scrapped in a minute or two. ”

Magazine plus rifle.

Isn't it just a light machine gun?

As long as it can solve the problem of continuous firing of the firing pin and the instantaneous deflagration of the bullet, it can be done.

Shi Xin nodded, "But if it is rapid-fire, there is bound to be the problem of overheating the barrel, and it is too difficult in the process, Weichen has an idea, if the material and process cannot be improved, why not consider adding an additional cooling measure?" ”

Zhu saw Jile, "Shi Xin, you were born in the wrong era, if you were born a few hundred years later, and you are the weapons supervisor of the court, the world will be rewritten because of you." ”

Not...... Now it's because of me.

continued: "For the heavy machine gun, you must add a cooling device, you can consider adding a water cooling device outside the barrel, as for the rifle with the magazine, there is no need to cool down, you just need to improve the steelmaking process of the barrel as much as possible." ”

A light machine gun plus a water cooling device is not called a light machine gun.

I don't know what Makqin is like.

Unfortunately, I have never studied firearms, and I know very little about the principle and structure of light and heavy machine guns, so I can only make conjectures based on my own knowledge, and then continue to experiment.

Shi Xin's face was solemn, "Weichen knows." ”

He added: "But has Your Highness ever thought that in order to achieve continuous rapid fire, flint ignition cannot be done in this way, because it takes a while for flint to ignite the fuse and then ignite the gunpowder of the bullet tail." ”

Zhu Jianji said: "Of course Lone knows, so Lone didn't give you the design of this machine gun." ”

From this point of view, the Desert Eagle can't do it.

Shi Xin thought thoughtfully, "The bullet needs to be improved!" ”

He also said: "Your Highness's mortar design drawing, Wei Chen has seen it, it takes a little time when it is launched, and it also takes a little time to explode after landing, which gives the enemy a chance to react and dodge, if it can explode when it lands, it will greatly increase the power." ”

Shi Xin suddenly excited, "If the bullet can ignite the shot instantly, then the mortar shell can also use the same principle!" ”

Zhu Jianji was really amazed.

Shi Xin actually wants to engage in modern firearms and bullets?!

National treasure!

Shi Xin is the national treasure of the Ming Dynasty!

Sent it.

There are such people in the Armament Warden.

laughed and said, "Shi Jianzheng, it seems that your good days are over." ”

Shi Xin was puzzled.

Zhu Jianji said: "From today onwards, the Lone Association will arrange manpower to carry out the strictest monitoring of the periphery of the ordnance superintendent, that is to say, from today onwards, the ordnance superintendent will become the most mysterious and important department of the Ming Dynasty, and in the future, the entry and exit of the ordnance superintendent and even daily life will be strictly monitored." ”

Including a steelmaking mill and a refractory brick production workshop.

This technology is absolutely not allowed to spread to the people, let alone abroad!

Shi Xin breathed a sigh of relief, "Your Highness doesn't want to scare Weichen, you still think it's something, Your Highness rest assured, Weichen on the side of the Ordnance Supervisor has already been selected, and those who remain are loyal people." ”

Zhu Jianji shook his head, "That's because no one knows what your ordnance supervisor has done and what kind of impact it has on this world, and when the time comes, the world will be shocked when the young army is equipped with rifles and machine guns, and there will be many people who will come to steal technology, and some of you will also face all kinds of temptations, and what you have to do is to prevent such a thing from happening!" ”

Once light and heavy machine guns, mortars, and modern bullets are made, it will be the nuclear weapons of the Ming Dynasty.

It is a big stick to enter the world.

Taking a deep breath, "In addition, Supervisor Shi is going back to tell all the ordnance supervisors, craftsmen, as well as the subordinate steelmaking mills and refractory brick production workshops, that they may be independent from the Ministry of Industry, and when the time comes, they will be under the jurisdiction of the East Palace, and the orphan will add thirty percent to everyone's salaries!" ”

This is the foundation of Daming industry.

It must be raised!

And...... And send them a house!

Zhu Jianji planned to plan a military industrial area to be specially guarded by the army.
