Aztec Eternals

"Given the Lord God, an invincible artifact!... The cannon exploded... exploded..."

A flock of crows flew from the high sky, leaving a "quack" sound of joy. Shulot sat under the zenith of the big tent, pinching the letter from the casting master, his face changed blue and purple. After a while, he calmed down, took a deep breath, and read patiently again.

"Your Majesty, more than two years ago, you left a lot of messy and vague divine revelations, and mentioned the stubby mortars specially used for siege..."

"It's messy, and the language is unclear." Seeing such a frank comment, Shirlot raised his brows and clenched his hands.

However, this is also true. In many cases, the so-called "God's Revelation" is just an impression of him, the correct technical direction, and the description of the shape of the creation. As for how to realize it and what the technical details are, it is up to the professional craftsmen and masters to slowly explore and solve the difficulties one by one.

In such a process, the progress of the master craftsmen's ability is obvious. Just like Tilipi, who was exploring cannon casting, he has built cannons for many years and has accumulated a lot of experience, and he can even research and manufacture mortars on his own.

"...You said that the length of the gun barrel determines the range, the size of the caliber determines the power, and the weight of the gun body affects the maneuverability... For heavy siege artillery, the larger the caliber, the better, but the range is second. Of course, the siege gun The weight can be increased, as long as it can be transported, even if it is slower..."

"According to this idea, I designed a new siege mortar. Its length is about one and a half meters, the caliber is between seven or eight inches, the stone bombs are loaded with thirty kilograms, and the weight is more than 800 kilograms..."

Seeing this, Xiulote pondered and picked up a pen to calculate.

The bronze cannon is one and a half meters in length, with a caliber between seven or eight inches, or 22-26 centimeters. Hekou stone bullets are about half a catty of 6-6.5 cm stone balls, with a volume of about 1000 cubic centimeters. According to the standard density of stone, 2.8 grams per cubic centimeter, the closing bullet is indeed around 30 pounds. A stone bullet of this weight, converted into pounds, can be a full 33 pounds! And if it is replaced with a closed iron ball with a density of 2-3 times, the power is...

"Well, the iron bullets that are widely used in Europe are still too extravagant for the current alliance. On the contrary, the alliance has enough manpower to polish the stone bullets. After the stone bullet hits the city wall, there will be shattering splash damage. , more suitable for the current alliance..."

Shilot pondered for a while, and on the straw paper, he estimated the shape of the bronze cannon.

The density of bronze is three times that of standard rock, at about 8.4 grams per cubic centimeter. The 800-jin bronze gun is about 50,000 cubic centimeters. According to the calculation formula of the hollow cylinder, the inner diameter is 12-13 cm and the length is 1.5 meters, then the outer diameter is...

"24-25 cm outer diameter? Artillery with a wall thickness of 6 cm?"

With this in mind, Shirot's face showed surprise. Such a short, short and thick cannon is simply...

"It's just a lump of bronze! This... Kingdom's cannon casting technology still has a lot of room for improvement! Huh... With the current technology, it is the only one who is stupid, black and thick, and desperately trying to increase its power. choice."

Shulot held the pen and stared at the bronze cannon that he would draw. After a while, he made a "tick" at the bottom. Then, he looked at the letter again.

"Your Majesty, the difficulty of casting this kind of stubby artillery is much easier than that of long-barreled artillery. Although the Casting Artillery Bureau took a year or two to build the first one. But with this template, it can be made this year. Three... no, five!... Please wait and see, even if I, Tilippi, tried my best to kill my apprentice, I will build enough siege artillery for you!"

The outspoken master of gunsmiths made a letter and made a promise that was not necessarily reliable. Then, his tone was half excited, half panic, describing the details of the test gun.

"When we tested the gun for the first time, we used five kilograms of gunpowder and fired it at a forty-five-degree angle prescribed by His Majesty. The range of thirty kilograms of stone bullets was about one hundred paces, and one and a half of them hit the ground on the soil. The deep pit of rice... The second time I tested the gun, I added ten kilograms of gunpowder, and it took more than two hundred steps to fall into the woods, breaking several trees! Your Majesty, this range is enough to reach the bombardment of the city wall. , and don't worry about the crossbow at the head of the city!"

Seeing this, Shiloh's eyes flashed. According to the parabola formula, the projectile range is related to the square of the muzzle velocity and is affected by air resistance. The kinetic energy given by the burning of ten catties of gunpowder is about twice that of five catties of gunpowder... No, considering the possibility of insufficient combustion, it should be less than twice. The kinetic energy is proportional to the square of the initial velocity, which is proportional to the range, and then the air resistance value...

"If the range of five jins of gunpowder is less than 100 steps, then ten jins of gunpowder will definitely not reach the range of more than 200 steps...Tilippi, my master casting master, you are slapping your chest again! ..and, such a range, even for a mortar, is a bit small. The airtightness during firing needs to be strengthened..."

Shirott picked up the pen and was about to write down the replies to the scolding. But after he pondered for a moment, he put the pen down again, and did not write any criticism.

The last paragraph of the letter was the details of the blasting of the artillery, with only a few simple sentences.

"Blessed by the Lord God! The power of this mortar is as great as the thunder of the Lord God. The wood and stone are shattered, and even the city walls can't resist it! ... The artisans of the Cannon Casting Bureau and the Gunpowder Division are very excited, and they all decided to test it. Let's talk about the upper limit of the range of the artillery. Director Talaya also nodded in agreement and provided a new type of gunpowder..."

"But I underestimated the power of the new gunpowder, adding a full 15 kilograms... This caused the explosion, killing two gunners. I have given their families a pension... Supreme Your Majesty, please show mercy and forgive my ignorant faults!  …”

Seeing this, Shulot lowered his eyes slightly. Although Tilipi was blown up and killed, but for such an outstanding master of cannon casting, he still has to be greatly encouraged and generously rewarded. Of course, this has to wait for the new mortar to really reach the front line and show the power of destroying the city and destroying the country!

"Your Majesty, when this letter arrives in your hands, the new batch of mortar clay molds should already be drying in the shade. This time, I will thicken the thick walls of the artillery again, increase the weight to one thousand pounds, and then Tighten the copper hoop on the periphery! And with such reinforcement, this siege artillery will definitely be able to launch heavier stone bullets, load more gunpowder, and shoot at longer distances! They are bestowed by the Lord God and inspired by His Highness. , an invincible artifact!  …”

"Huh? A thousand-pound mortar..."

Xiulote picked up the pen, UU read www.uukanshu. com calculates a little. With the addition of 200 pounds, the wall thickness of the artillery has increased by 1 cm, and the toughness will be further improved.

"Ha! Tilippi, my master gunsmith, you are on the road of stupidity and darkness, and you will never look back..."

Shirot laughed dumbly. Then, he began to calculate again, 45 degree parabolic fire, the shell height is about half the range. And if it can launch a 33-pound stone bullet and hit it on a hill that is more than one hundred steps away and more than one hundred steps high, then the city of White Snake Hill, which is in danger of being difficult to attack...

"Huh! If there is such a heavy artillery... all states and cities in the world, in front of the legions of the kingdom, are like weak girls, and there is no way to stop them!"

Shirott looked sharp and put down the letter. He stood up, walked out of the tent, climbed to the watchtower in the camp, and looked at the sky in the northeast. There, a sturdy hill city, like a tortoise waiting to be slaughtered, shrank in its shell. At this moment, a group of warriors from the kingdom are escorting two really weak girls, slowly entering the camp.
