Since returning to Truchen and determining the development strategy for the Khanate in the next five years, people have been watching agriculture, animal husbandry, foreign affairs, commerce and other affairs, Qitad has put his focus back on industry.

He knew very well that with the current strength of the Khanate, if he still looked like the moment, although it might win a certain war against Russia, it would not be enough to give it a decisive blow.

In the shorter period of time in the future, it is impossible to increase the population on a large scale, weapons with greater lethality and wider killing are the king.

Therefore, creating artillery that is truly close to the level of later generations has become the top priority.

Compared with the extremely ammunition-consuming machine gun, the large-caliber cannon is the first thing he needs to do.

At this time, Europe already had various standards for various battlefields, and various types of artillery with certain maneuvers. If he wanted to imitate it, there would be no problem.

However, there is a problem with the artillery of European powers without exception.

That is, they have not yet fully entered the stage of iron-cooked iron, let alone more advanced steel, and the amount of cannons used is much higher than that of muskets.

This caused them to be able to make the artillery extremely thick. Even so, if the iron material used was still used, the risk of blowing the chamber still exists.

So, the bronze cannon became the only choice.

The Khanate must have large-scale copper mines in Akto and tin mines in Stavropol. It is said that it is not a problem to use the army's bronze cannons on a large scale before the unborn Napoleon.

But in recent years, even with the steam engine, Qitade has not launched a trial production of bronze cannons, and still uses a large number of short-barrel lightweight cannons.

This has something to do with his strategy.

If a nomadic tribe pushes a large number of cannons to the battlefield before its strength reaches a certain level and uses it on a large scale, Russia will obviously first regard you as an object that is eager to get rid of it.

Although he owns a new type of musket, it is nothing to the Russians.

But cannons are different. Once you have this item and can be produced efficiently, you will be a complete power.

With the arrival of the Junggars and Han farmers, Qitade has a certain strength. According to common sense, he should be dormant for a while before talking about it.

But as Vobassi brought the news back from Poland, he immediately realized that there was not much time left for him.

You have to get on cannons.

The second year after returning to Truchen, he began to take the lead in the trial production of iron materials used for cannons in Truchen's laboratory.

Since there is no specific tool to detect the iron composition, he can only try it repeatedly. Fortunately, he has two secret techniques: steam forging press and manganese material.

In the past, although we had these two secret techniques, it is unlikely that we would completely stabilize the process of ore dressing, smelting, training, forming and other processes in a short period of time, but after five years of repeated exploration, we finally made progress.

Of course, the technology they had before was used for muskets, and a mere liang of gunpowder would not have any impact on his barrel.

So far, his skilled craftsmen have been able to judge the hard iron, pig iron and steel by the naked eye and the sound after the knock. In addition, Jeddah and Sangkun, who have received a whole periodic table of Qitad, use more advanced technical means to obtain large-scale steel.

Using steel instead of bronze to develop cannons is the only choice for Qitad.

He must have a generational disability.

And this generation difference is the weight of the artillery.

After a year of exploration, he finally developed a steel cannon with a caliber that was the same as the Napoleon bronze cannon in later generations, but the body tube ratio was only ten, while the body tube ratio of the bronze cannon was fourteen.

At this time, Truchen's craftsmen have gradually mastered and stabilized the process of adding heavy materials.

So, his twelve pound steel cannon weighs almost half that of Napoleon's bronze cannon!

"Boom..."

In March 1759, late winter and early spring, a thunder sounded outside Magar City.

To the northwest of the castle is a flat prairie, which has now been surrounded and become the military camp of the Qitade Guard Brigade.

This is a military camp that covers a huge area. In order to practice and test artillery, the length of its large campus reached five miles!

Two miles away, a new steel cannon with a delicate black light had just fired a shot!

I saw that the cannon was about one meter and one caliber, and the caliber was exactly the same as Napoleon's twelve-pound bronze cannon.

The gun body weighs 600 kilograms, and the gun mount and the wheel weigh 600 kilograms. When pulled by two pack horses, the gun mount can be loaded with twenty parts of ammunition weighing 480 kilograms, including ten parts of solid ammunition, five parts of shotgun, and five parts of grenade.

The total weight is 2,000 kilograms. In fact, it can be pulled with a Caucasian pack horse. To be safe, one more pack horse is used, and a spare horse is used, at least four horses are needed.

The wheels are not all made of iron, but are wrapped with rough glue, which causes less damage to the iron wheel.

Such things are available, and it would not work without the same units of rice, decimeter, centimeter and millimeter introduced in advance by Qitade.

After five years of experimentation, they discovered a secret:

The corresponding gunshot length is one meter and one 11 cm, and then accordingly:

Fifteen kilograms correspond to one meter and two, and twelve centimeters;

Twenty kilograms correspond to one meter three and thirteen centimeters;

Thirty kilograms correspond to one meter five and fifteen centimeters.

In the end, he abandoned fifteen kilograms and twenty kilograms of artillery, leaving only twelve kilograms and thirty kilograms.

For him, the cannon named "Truchen 1758-12 Slide" by him was the main force in the field with twelve jin. It is enough to use "Truchen 1758-30" when encountering a solid castle.

The one who just launched was 1758-12. Not long after, two people ran into front.

"Shan, the '1758-12 slip' five-degree elevation range is 1500 meters

"Well, use the '1758-12 line' to shoot"

Four guns of different sizes were scattered next to the cannon that had just been fired.

After hearing this, Kang Xiaozi, the commander of the Prince Guard Brigade, quickly issued an order.

Also with a front-mounted smoothbore gun, a solid artillery weighing 12 kilograms requires much more personnel than before, and it cannot be operated by every dragoon like before. Special artillery personnel must be used.

Therefore, Qitade drew half of the personnel from a thousand dragon cavalry to practice the new cannon.

Such a cannon requires at least four people.

I saw a dragoon taking out a portion of solid ammunition from the gun mount. Unlike short-barrel artillery, if you want to push a twelve kilograms of shells, the charge amount must reach at least this number. One ammunition is twenty-four kilograms!

The shells are naturally separated from gunpowder, but when the cannons fall into place, they will be placed together.

Carry this ammunition to the same size as before, but looks thicker than the muzzle of the rifled gun.

There are two medicine bags, one is the smaller one, which is the lead-in medicine. It is cut open with scissors and poured into the cannon chamber. The other soldier quickly pushes it to the bottom with a squeezing rod and compacts it.

Then pour in the launching medicine, push it to the bottom and compact it. The third soldier put a solid shell weighing 12 kilograms into the muzzle. At this time, he needs to replace an iron rod and push it to the bottom and compact it.

The soldier who transported the ammunition just now inserted a lead wire from the hole. The diameter of the lead wire was just flush with the hole. However, the head end was coated with a layer of gum that was easily ignited, about two centimeters long, which was straight and harder than other parts of the lead wire. It was easy to insert and did not hinder the ignition and induced drugs at all.

The lead wire is about ten centimeters long and it is burned for about ten seconds. For the Truchen artillery who used this cannon for the first time, the lead wire should not burn too long or too short.

Ten seconds were produced by the laboratory led by Qitade himself after countless experiments.

Kang Xiaozi held a small golden flag, as if only one cannon is fired now, but if he is on a battlefield where killing sounds are shocking, the artillery responsible for lighting the lead can only observe the small flag in the gunner's hand.

Kang Xiaozi waved the little yellow flag in his hand down hard, and the fourth soldier immediately picked up a piece of charcoal with tongs, and then ignited the lead!

"Boom..."

The same round solid bullet snatched the chamber, unlike the first smoothbore gun, because there was rifle inside, the shell still flew forward along the rotational trajectory of the rifle after leaving the chamber!

After a while, two more people ran over in front.

"Da Khan, this time the first time the shell was about 1725 meters! And it hit the target accurately!"

Qitad nodded.

The Napoleon bronze cannon in history, because the body tube ratio is larger, when firing smoothbore cannons, twelve pounds can fly 1,800 meters, and when firing ray rifled cannons, they can fly 2,100 meters!

In order to reduce weight, I sacrificed part of my range.

But this is enough. 1500-1725 meters, that is three miles to three and a half miles. This is the best distance that a five-fold telescope can observe at this time. It doesn't make sense if it is far.

What's more, he is also planning to use this kind of artillery on the ship. At this time, the range is meaningless on the warship at this time. On a ship with strong winds and waves, the width of the body tube is too large. Moreover, if you shoot three miles away, it would be good if you can hit one of the ten shells.

Most of them shoot at the target after reaching one or two hundred meters, so the cannon with a large body tube is actually of little significance.

Lightweight and easy to install, this has always been his pursuit.

Then a thirty-pound steel cannon was fired. The length of this cannon was 1.5 meters and a caliber of fifteen centimeters. The gun body, gun stand/wheel, and the total weight of its own ammunition was nearly 4,800 kilograms. It requires six pack horses to pull it. If it is a horse that pulls the ammunition, at least ten horses are required.

But its range is still only about three to three and a half miles, in order to attack the enemy's fortress.

The emergence of this artillery made Qitad, who had always pursued convenience, look very strange. Obviously, in the near future, he would not only consider defeating the enemy in field battles, but also attacking the enemy castles, especially like the Russians, who built the castles with all marble stones!

Finally, the shot was a small cannon similar to the previous 100-pound short-barrel cannon, but it was not the previous tiger claws that were lying on the ground, but three brackets!

Two brackets are in front, and one holds the tail of the cannon.

If people from later generations can tell what they are at a glance.

Mortar!

Yes, since I have mastered the production of copper shell bullets, it has been natural to get the mortar out.

It is also one hundred kilograms, with a conical shape on the upper part and a copper bullet weighing about five kilograms. The bottom of the bullet has a small depression. It is extremely thin. There is a steel needle at the bottom of the gun. After putting it into the barrel, due to the effect of gravity, the sharp steel needle will pierce the bottom of the bullet, then pass through the ammunition, and ignite the gunpowder through friction.

"Boom!"
Chapter completed!
