Three Kingdoms, at the beginning of the game, recognize the thief as the father, hit the spectacle,

I haven't seen it for a while, the Science and Technology Department is much more complicated than before. In that courtyard, you can also see a lot of metal smelting facilities.

For example, when he just entered the door, Zhang Yan was surprised to find that there was this small mud stove in the corner, which was beyond his expectation.

"This thing...is this used when smelting metal?"

"No, the ones piled up next to them are some clay models."

"First use the clay cannon body to make an iron mold, and then use the iron mold to cast a bronze cannon... Hehe, as expected of Ma Jun, he came up with this kind of gameplay nearly 2000 years in advance. It is really exquisite."

Taking a general look at the situation in the Science and Technology Department, Zhang Yan nodded in satisfaction, then took Ye'er to greet everyone present, and went to the backyard of the Science and Technology Department under the guidance of everyone.

Near the corner of the backyard, Yang Feng, Xu Huang and other military generals had already arrived, and they were pointing at the officials of the Science and Technology Department who were busy not far away. It's a curious look.

In front of them, in the center of the courtyard, there was an open space about 30 meters away, where several wooden targets were placed, and a group of officials were busy working near the targets.

As for Ma Jun, his face was full of excitement at the moment, while dancing and gesticulating with Xu Huang and others, he was talking loudly about something.

After Zhang Yan arrived, these people stopped arguing and greeted Zhang Yan one after another.

"Hehe, Deheng, long time no see."

"Today I heard that you finally developed the first cannon. I was excited for a long time. I couldn't help but be calm when I took a nap at noon. I just waited for your invention to show its strength."

"How about it, do you have any samples, let me have a look first?"

Chapter 24 The first round of test firing

Smiling and greeting Ma Jun, Zhang Yan first nodded to each other with several generals present, and then turned his attention to Ma Jun, the absolute protagonist of today.

When Ma Jun saw him coming, he hurriedly stepped forward to greet him with a smile, and at the same time showed off the things behind him as if showing off a treasure.

"Thank you for your concern, my lord. The trial model of the Type [-] artillery has been produced, and it is the one in front of you."

"We used this artillery..."

Eloquently told Zhang Yan a lot of experimental data, Ma Jun is like a child at the moment, showing off his new toys to his relatives and friends.

But no matter how much he said, Zhang Yan didn't seem to listen.

Zhang Yan's attention was immediately attracted as soon as the big yellow gun barrel appeared in his field of vision.

Although it is made of bronze, judging from the appearance of the cannon body, there is no trace of cyan.

As we all know, the reason why bronze is called bronze is not because the color of the alloy itself is a light turquoise, but because 90.00%—or even 90.00%—of the bronzes unearthed today are long Corroded and rusted in the earth burial of time, the surface of the copperware is covered with a thick layer of verdigris.

If we really want to talk about the original appearance of "bronze", we have to start with the composition of this alloy.

The so-called bronze is actually an alloy composed of pure copper, tin, and lead in a certain proportion, among which copper-tin alloy is the most famous.

The main component of this metal is reddish copper, mixed with white metal tin, and the whole alloy shines a faint bright yellow color when it is just out of the furnace.

And this is also the origin of the very famous "flash gold" in the alchemy allusion of "turning a stone into gold".

For example, the cannon surrounded by everyone now has a faint golden glow all over its body, giving people a rather mighty and luxurious feeling.

It's no wonder that in the Ming and Qing dynasties of later generations, the large artillery made of bronze also had a very powerful and domineering name-the bronze cannon of "Shenwei Invincible General".

From the appearance alone, this kind of large metal creation is very easy to bring a sense of visual impact to people.

"Tsk tsk tsk."

……

"so big."

……

"It's so thick."

……

"And it's very long."

There was a burst of commentary around the cannon body, while Zhang Yan clicked his lips softly, looking at the various details on the cannon with great interest.

The more he looked at it, the more he felt that the words "silly, big, black and thick" lingered in his mind like a demon, stretching endlessly.

I saw that the cannon was about one meter long as a whole, occupying the main part, and it was the thick and long barrel that caught people's attention immediately.

Zhang Yan only looked at it with the naked eye, and then made a few gestures with his hands, and found that the thickest part of the gun body was about ten centimeters thick, and the gun bore was more than two inches. It was like a big mouth gushing out some terrifying roar, which made people shudder.

Under the gun body of about 1.4 meters is a suggested gun mount made of a two-wheeled trolley and a hook lock.

"Hehe, this is the design of the attack gun... As for this kind of hook lock, is this a tiger crouching gun?"

"Hehe, Ma Jun is a bit interesting. I didn't expect to combine the advantages of the two types of artillery that will be used as field artillery and fortress artillery in later generations."

Narrowing his eyes slightly, Zhang Yan never expected that the opponent actually used a push-pull design for convenience and movement on the first type of artillery designed by the opponent, and the iron chain hanging on the side was obviously to be tested later. During the process, the fixed assembly used to hook on the ground to prevent the gun from recoiling too much due to recoil.

This act of concentrating two different artillery advantages made Zhang Yan feel refreshed.

Inevitably, he also had a slight sense of anticipation for Lujiang's first firearm: the "[-]-type artillery trial model".

Before he came here, he originally thought that Ma Jun would at most be able to successfully ignite and test fire this time. As for parameters such as maneuverability and accuracy, he didn't have any expectations at all.

But now it seems that he may have underestimated the other party too much.

The so-called fortress gun, that is, the artillery is fixed on the gun position of the city wall through iron chains, and the twisting between multiple iron chains is used as a buffer when the artillery fires, which can greatly protect the life safety of the gunner and the artillery. hit accuracy.

For example, the tiger crouching cannon in the Ming Dynasty was a typical fortress cannon.

When it was at its peak in the mid-Ming Dynasty, many people also chose to remove the tiger squatting cannon from the fortress, carry it in a horse-drawn cart, and then fix it on the position after transporting it to the destination, and use it to attack the extremely strong city wall. City.

As for the field battle, that is, when the two armies meet in the field, it is another type of artillery, the so-called offensive artillery.

In fact, to put it simply, the attack artillery is a kind of shotgun. When firing, in order to kill the enemy's vitality to the greatest extent, some of them are very fine "iron" or even iron nails as ammunition.

As long as this kind of attack artillery is shot down, there is no need to expect dozens of miles of longitudinal erosion, but fan-shaped erosion of tens of meters within the coverage of artillery fire can still be easily done.

Plots like the cannon hitting mosquitoes described in those film and television dramas or second-rate novels can really only exist in the hearts of creators who have not experienced the baptism of war.

Throughout the development period of artillery, offensive artillery has always played a very important role in field artillery, especially in the field artillery on the Eastern battlefield.

In order to adapt to the high-speed maneuvering on the battlefield, this kind of artillery will naturally choose to support the gun body with a wooden cart, and then use a horse-drawn cart as a traction, that is, the very common horse-drawn artillery or hand-push artillery cart.

Now, Ma Jun has applied the characteristics of these two types of artillery to the Type [-] artillery, obviously having his own ideas.

"Look, my lord, this cannon is enormous, weighing more than [-] Han Jin. It was very clumsy on the battlefield, but once it is deployed, it is inconvenient to move easily."

"And with this kind of two-wheeled cart installed, and then pulled by a horse, it can be easily transferred."

Sure enough, Ma Jun did not follow the gourd, but really understood the information about the artillery that Zhang Yan had shown him.

Afterwards, just listening to him change the subject, he smiled and patted the huge cannon body with his hands, and a satisfied smile appeared on his face.

"As for the chain..."

"My lord, the 'caliber' of this cannon is about two inches and one centimeter, and it is designed to be twenty times the diameter. Once fired, it will be difficult for three or five soldiers to hold it steady."

"At this time, it is time for this iron chain to play a role."

……

"Well, I understand I understand."

"Use an iron chain to tie it to a fixed object to keep the gun body stable and at the same time ensure the aim of the gun, right?"

"Don't look at me like a literati, Ma Jun, don't forget, I gave you all this information, so I naturally know it clearly."

Somewhat indifferently thinking about Ma Jun, he waved his hand, and a golden light burst out from Zhang Yan's eyes.

"Instead of talking about this, it's better to wait for the actual battle and demonstrate the power of this artillery for me and the generals present. This is true."

"By the way, you just said [-] times the diameter, right? So, this kind of artillery has reached the level of a 'howitzer'?"

He touched the smooth cannon body with satisfaction. Although Zhang Yan's first impression of this kind of cannon was a bit silly and thick, this does not mean that the casting of the Type [-] cannon is very rough. On the contrary, the inside of the cannon and the Near the muzzle, every place has been polished clean, not even a trace of burrs can be seen, let alone trachoma or air bubbles.

The reason why Zhang Yan thinks he is simple is that there is no decoration on the gun body of this kind of artillery, and there is not even a trace of pattern to be found.

At the very least, Zhang Yan felt that if he branded the words "the first batch of trial production of Type [-] artillery" on the body of this artillery at this moment, it would definitely have a special flavor after a glance.

As for Ma Jun, he nodded amidst the questioning voices of "howitzers?" and "what is that?" from the surrounding people, with a somewhat proud look on his face.

Among the people present, apart from Zhang Yan, who had received complete military training, he was probably the only one who could understand what the so-called "howitzer" meant.

……

"Yes, my lord."

"This Type [-] artillery is exactly a standard howitzer."

According to the distinction method of modern artillery, all artillery can be divided into "cannon", "howitzer", "howitzer", and "mortar" according to the double diameter.

Among them, cannon refers to all long-barreled artillery with a multiple diameter of 45 or more. Those with a multiple diameter of less than 45 and higher than 39 are called cannons, which means the intermediate product of cannons and howitzers. As for those with multiple diameters below 39, It is called a howitzer.

There is actually no obvious difference between these types of artillery in terms of shells and excitation mechanisms.

If I have to say it, the larger the multiple diameter of the cannon, the more fully the acceleration of the cannonball will be, the faster the exit speed will be, and the straighter the trajectory of the cannonball will be.

In the early days of artillery without flowering ammunition, the larger the diameter, the greater the power.

Regardless of the fact that after the eighteenth and nineteenth centuries, there was a trend of using "mortars" in Western Europe, and later in the East, "mortars" such as "toys" with a multiple diameter of less than 10 were also large. Brilliant, but whether it is a mortar or a mortar, it is only after the emergence of flower shells that the artillery can have enough power.

In the early period of firing iron balls and shotguns, the power was directly linked to the multiple diameter of the artillery.

It can be said that in the entire history of artillery development, the multiple diameter is the same as the caliber, and it is an important data that can hardly be ignored.

According to the later military standards, there is no doubt that this type [-] artillery is a very standard howitzer.

According to the characteristics of the howitzer, its biggest advantage is that it is more "multi-purpose" than the cannon, and it is more suitable for various battlefield environments.

For example, some very well-known howitzer models often have the positioning and power of field guns, and at the same time can attack some targets inside the bunker according to the slightly arced trajectory.

In other words, at the end of the Eastern Han Dynasty, the howitzer was a sharp weapon that could not only lay flat and sweep thousands of troops, but also stand up and launch a general to break the city wall. It can be said that it is the most suitable type of artillery for Lujiang.

Satisfied, he squatted down and patted the barrel of the artillery. Zhang Yan didn't say much, just stood up and looked towards the shooting range not far away.

Afterwards, everyone seemed to have a tacit understanding and set off, making way for him in unison.

……

"Hehe, well, Ma Jun, it's useless to talk too much."

"This cannon was made for shooting. No matter how well you know its data, it's not as shocking as actually using it."

"I came here today not to listen to your data, but to see the effect of your test firing."
