Chapter 154 Carry out the troll to the end

Hearing that Shen Shuren had come up with some design requirements for the follow-up new firecrackers, Song Yingxing, Zhou Tiedan and others were still a little surprised, and quickly expressed their willingness to listen carefully.

Although Shen Shuren had also shown foresight in firearms technology before, he mainly did it piecemeal, changing bayonets, bullets, and odd accessories, and he had never shown his talent for the overall design of firearms.

Seeing everyone's expressions and reactions, Shen Shuren could guess what they were thinking, but he didn't take it seriously, and directly took out a sketch he had drawn casually recently, and a few text descriptions, while explaining:

"Today's Lumi guns, even though they have been repeatedly improved, are still slow to reload. Originally, the ammunition was divided and fired at least every [-] to [-] breaths. The old-fashioned guns that use matchlocks can be fired at [-] breaths.

After the Lumi blunderbuss was fixed with paper shells, it was already a lot faster, but at least it took nearly [-] breaths.

In contrast, the warriors on horseback and archery of the Tartars shoot continuous arrows when they meet the enemy, and they can shoot an arrow in three or four breaths, and they don't aim at random shots.Even if you aim a little, you can shoot an arrow in five or six breaths.

So I thought, if there is a way to improve a new firecracker right now, the range, firepower, and accuracy can all be shelved for the time being. The first thing to solve is the rate of fire.

Facing cavalry, bows and crossbows are only three arrows in front of the battle. If the bird guns can't even achieve this density, in the future large-scale field battles and battles, if the enemy rushes to the front, at least half of the benefits of firearms will be wasted.

I have led troops for two years, but I have to say that I was lucky before. I have never encountered a first-rate strong enemy, nor have I fought against a large army with large cavalry.In the future, when encountering Li Zicheng, Zhang Xianzhong, or even the Tartars, Erhe and Liu Xiyao will not be as easy to deal with as before. The firearms must increase the rate of fire. "

Song Yingxing and the others had no objection to the direction of their efforts. They also took a rough look at Shen Shuren's sketch, which was relatively abstract. Fortunately, it was drawn with a ruler, so it would not be crooked.

Song Yingxing pondered for a few seconds, then he understood, and asked: "So, the way Daotai hopes to increase the rate of fire is to cut off the barrel and load the ammunition from the bottom? This idea is similar to that used on cannons. The female gun Flang machine is somewhat similar."

Originally, Shen Shuren didn't know much about the history of artillery development in the Ming Dynasty, and he had never used a Frang machine, so he couldn't help being a little surprised after hearing Song Yingxing's comment.

He had just arrived in Huangzhou for half a year, and he took Zheng Chenggong as his younger brother, and Zheng Chenggong made him a red cannon.It was difficult for Shen Shuren to go from extravagance to frugality, and he used better and more advanced existences when he first came up, so he didn't bother to look for the Franc machine of the previous era.

He couldn't help but ask back: "What? Did Frangji reload from the back? What exactly is it like? Then why haven't you seen it on the Hongyi Cannon?"

Song Yingxing took it at his fingertips, drew him a sketch, and said, "I can't remember the details of this picture. It should be drawn like this. I also read it from Bi Shilang's "Illustration of Military Weapons."

Shen Shuren looked at it very seriously, and saw that what Song Yingxing drew was a musket similar in structure to the Mauser rifle of later generations, with an opening on the top of the magazine, allowing the pre-loaded gunpowder and shells to be loaded directly into the gun barrel. At the tail of the gun, it is connected with the barrel.There are also some bayonet locking mechanisms for fixing.

Behind the blunderbuss, there is also a piece of solid iron cast integrally with the front barrel, which is used to prevent the blunderbuss from being bounced by recoil. After all, when firing, the recoil force on the blunderbuss is the same as the forward force on the shell. The same size requires a very strong rigid locking mechanism to resist (not much explanation, see the picture in this paragraph).

Shen Shuren stroked his beard and pondered, and asked inquiringly: "It seems that this method of loading from the rear is quite mature, it is nothing more than a female gun needs to be equipped with a few more sub-guns, and they can be used interchangeably—then why did Hong Yi later use it?" But the cannon didn't use this method?

Even if it was a Flang machine, when He Yilong retreated in May, our army captured two thousand-jin Flang machines that were too heavy for the enemy to take with them when they retreated. filling.I have heard of the mother and child guns, but I always thought that the child guns were also inserted from the front of the barrel. "

Song Yingxing shook his head triumphantly, and took the opportunity to show off: "You don't know, this Frang machine is only used on three-hundred-jin and smaller models, and the thousand-jin Flang machine is no longer good, because This kind of air leakage and fire leakage is too serious, it can't hit far, and it is easy to burn the gunner.

As for the Hongyi cannon, it costs three to five thousand kilograms and charges more than ten kilograms. With such a great power, who would dare to use the design of separating the bullet-loading gun and the mother gun barrel?Once fired, the pushback force of the sub-gun could not withstand it at all, it was tantamount to exploding ten catties of gunpowder directly on the gun emplacement, and I am afraid that the gunner would be killed! "

Shen Shuren nodded, and quickly realized: breech loading, in the final analysis, is still a problem of poor airtightness and difficult recoil.

However, from what Song Yingxing said, it can also be deduced in reverse: the more powerful the gun, the more it needs the bottom of the barrel to fit tightly and be firmly integrated.The less powerful the firearm, the more relaxed it is.

After figuring this out, Shen Shuren also realized that this was the same as his own original idea. It is not that breech-loading guns cannot be manufactured, but high-pressure guns cannot be manufactured, and low-pressure guns are still possible.

Just like in the early 20th century, all countries were dealing with rifles and machine guns at that time, and the bolts at the rear of the barrels of rifles and machine guns were locked at the moment of firing and would not retreat.

But at the end of World War I, after the appearance of the submachine gun, the tail action of the submachine gun was "inertially locked", that is, it was not completely locked, and it would slide when pushed by the recoil.

The advantage of a submachine gun is that it can be fired quickly with low recoil, but the disadvantage is that it can withstand low chamber pressure, so you can only use pistol bullets with a much smaller propellant charge, and the effective range is much shorter.

In the same way, when breech-loading firearms appeared in modern times, the first to overcome breech defects were pistols and sprayers.For example, the old-fashioned double-barreled shotgun that looks similar to the S686 in Chijili, as well as the later improved lever-action rifle and revolver, are the first batch of varieties that are loaded from the bottom of the barrel.

These guns do not require any post-industrial technical reserves, and they have already been manufactured with the little industrial foundation before the Napoleonic Wars.

In contrast, many time-travel novels like to make rifled rifles and rifled guns, which seem to be more troublesome.The self-tapping rifling bullets of the Minnie bombs were only available in the middle of the 19th century and after the Second Industrial Revolution in history, and they were much more difficult than what Shen Shuren wanted.

After smoothing out his ideas during the discussion, Shen Shuren also took the opportunity to formally put forward his needs: "So, I don't want to build a new firearm with a lot of charge and a long range. As long as it can be reloaded, it is best to pre-install multiple shots. Projectile, fast feed.

For example, make a circlip dial, and then make a honeycomb-shaped bullet nest, with a shaft in the middle and six vacant positions around the side, and the trigger will turn a sixth of a turn..."

While talking, Shen Shuren supplemented the drawing, and drew the rear-loading sprayer and revolver in his mind.

Of course, he also knew in his heart that his current industrial precision and steel quality, and the processed pistols must be less accurate than the Western revolvers at the end of the 18th century.The airtightness is also worse.

The earliest revolver of the Westerners, billowing black and white smoke came out of the cylinder as soon as it was fired. When it came to him, it is estimated that it would not only emit thick smoke behind it, but also burst into flames directly.

It is estimated that gunners who use revolvers will have to wear gloves with better fire resistance and heat insulation to prevent the skin on their hands from being burned by the fire from the gun.

Song Yingxing is obviously also knowledgeable. After listening to Shen Shuren's description, he has also imagined a product that "miniaturizes the [-]-jin Flang machine to a weight of [-] catties and turns it into a rotary cylinder for bombs".

So he couldn't help frowning, and told Shen Shuren about the above worries: "...My lord, you have to be careful about this matter. The effective range of today's bird guns is at least 150 steps, and the shotgun is only seventy or eighty steps away." step.

This is still dealing with unarmored people.If you use shotguns against heavy armor, the damage will be no more than [-] steps. This is also what you have concluded from the previous battle with Erhe.

Now it is changed to leaking air and fire from the breech. The old man compares the power of the one-piece Flang machine and the mother-and-child gun Flang machine by analogy, at least one-third of the gunpowder thrust must be released, or even more.

At that time, it will be completely useless to use a slug, and it may not be accurate and has no range. It is completely tasteless.It can only be shotguns, and the new gun is equipped with shotguns, and the range is further weakened. I am afraid that it can only break heavy armor in [-] steps and light armor in [-] steps.This is less than one-third of the range of the crossbow, so what's the use? "

Song Yingxing could see that it was impossible to make "rifles" with such a low chamber pressure, and only pistols and guns could be made.

But after Shen Shuren heard it, he was not disappointed at all, but complacent: Look, Song Yingxing estimated that this weapon still has at least 40 steps of powerful damage to unarmored targets, and 20 steps of heavy armor damage. There is great hope for it to come out!This is enough!
The pistols and spray guns of later generations can effectively kill at 50 meters?Wouldn't it be 40 steps equivalent to the Ming Dynasty?
He didn't ask too much, and said very easy-goingly: "It doesn't matter if the range is short. The short range is nothing more than the fact that in the future, you can't use this weapon to resist cavalry on foot, and you won't be able to fight with the Tartar horse archers.

But what we have to deal with right now is mainly thieves. It is enough to provide a few rounds of fierce firepower before and at the last moment of close combat.In addition, since the bore is lowered, the range is shorter, and the charge is less, I don't think the barrel is as long as it used to be.

Originally, the pipes were five feet long, but the new ones can be reduced to three feet, so that cavalry can also use them on horseback.If it is shorter, it can even be used with one hand, just like a hand gun.

After it is built in the future, we will not equip light cavalry or bow cavalry, but only equip cavalry for charging and close combat. Isn't it much better than the three-eyed gun? "

The three-eyed blunderbuss of the Ming Dynasty had a very short barrel but a long handle.Because the tube is short, the range of that thing is worse than that of a pistol, so it is equipped for melee cavalry. After three sprays, it will be used as a long-handled hammer.

If Shen Shuren can produce a carbine nozzle with a medium-length barrel, or simply a revolver that fires shotgun iron sand, it will definitely be useful for melee assault.
