In fact, the principle of modern artillery is not complicated. The firing pin on the breech block hits the primer of the artillery, igniting the propellant barrel. The barrel burns and pushes the shell forward, starting to rotate and accelerate along the rifling.
The moment the cannonball is pushed out of the barrel by the ultra-high chamber pressure, it begins to self-propelled rapidly and flies forward at a speed of thousands of meters per second.
The excess propellant sprayed out of the barrel, huge flames rose into the sky, air waves roared at the muzzle, and a shell flew toward the target like a mountain.
The development of the earth's civilization for hundreds of years still continues this simple principle, but it is just based on this principle that the values of each link are constantly improved.
Promote materials science and metallurgical forging technology, and ultimately make the barrel stronger, allowing the entire artillery to withstand greater bore pressure and increasing the range of the artillery.
Research chemistry to improve the combustion performance of gunpowder, make the propellant of artillery more efficient, increase the power of artillery shells ten to a hundred times, and make artillery more powerful and have a longer range.
Precision machining makes the entire artillery more accurate and has smaller errors. This allows the entire artillery to maintain a more stable state when firing to achieve higher accuracy.
Modern artillery can easily launch shells to enemy positions 20 kilometers away, and the explosive power of each shell is enough to shake the opponent's position.
Because there are not such high war requirements, until now, the self-propelled howitzer troops of the Eilanhir Empire are still using old weapons and equipment.
Older models of howitzers do not have automatic loading machines and rely on manual loading, so the rate of fire is relatively slow.
There is no way, who can reduce the demand for war, and most of the defense budget has been snatched away by more new-type troops...?
Even so, the 155mm caliber self-propelled howitzer of the Ailanthir Empire is still the latest, strongest and most standard war weapon. Its roar represents the will of the Ailanthir Empire!
The fuze of each cannonball has been verified by puppets on the automatic production line. Each one is a standard part produced according to the most standard process, and the pass rate is close to 100%.
The robots are not lazy, so they can ensure the absolute quality of the product. Whether it is raw materials or production processes? There will be no problems.
Products produced by such a standard assembly line are reassuring and despairing for the enemy. Every cannon? Every shell? Even every grain of gunpowder is a product that has passed strict inspection. Such a war machine?
Every detail is perfect.
Following the gunner's order, the muzzle of this long-barreled 155mm self-propelled howitzer ejected a huge flame. For a moment, the entire artillery position began to shake, and the sky was covered by the blown dust.
At the same time, another howitzer next door also sprayed out flames. The flames rolled in the air until they were covered by dust, and they continued to expand and jump.
Three 155mm caliber howitzer battalions? A total of 54 howitzers roared one after another, launching 54 shells into the enemy's position in one breath. The power can definitely make the opponent doubt his life.
The soldiers of the Rock Empire stationed on the city wall did not know that someone was already attacking them more than ten kilometers away from them.
These soldiers still stood loyally on the city wall, leaning on their spears and looking into the woods in the distance. Under their feet was the thick city wall, and outside the city wall were densely packed tents.
There are approximately 15,000 members of the Holy See's Holy Army stationed here, and there are also 10,000 soldiers from the Flame Empire who have come to help in the battle.
Such a huge army? Coupled with the heavenly sword weapon that destroys the world, the Rock Empire can be said to be strong this time...
"Yo..." The long and sharp sound of breaking wind made a Rock Empire soldier on guard frown. He heard the sound getting closer and closer, but he didn't know what could make such a strange sound.
He listened carefully until a black shadow suddenly fell beside him and hit the city wall at his feet, making a muffled sound.
Before he could even look down to see what had fallen, the collision fuse ignited the high explosives loaded into the shell.
The explosion suddenly engulfed the soldier standing guard, and then the rapidly expanding air flow swept away countless shrapnel and gravel, instantly shredding everything in the way.
The ballistae made of thick wood was directly cut into wood fragments by the airflow, and with the metal shrapnel inserted on it, it ran rampant and made the soldiers at the top of the city flip over.
The soldiers who were directly hit had basically nothing left, and the soldiers who were slightly closer now only had stumps and broken arms.
And these remaining stumps and severed arms have now turned into flying fragments that kill and injure others, sweeping up those soldiers who are further away.
The thin breastplate was easily penetrated by shrapnel, and blood spattered everywhere. The screams continued, but were covered up by another explosion in the next second.
"Boom!" Another explosion sounded in the city. The shell blew off the roof of the entire building. The brick walls collapsed in the explosion. All the soldiers stationed in the house were buried under the rubble.
.
"Fire from the sky! Fire from the sky...fire!" An officer looked desperately at the scene where a section of the city wall was directly hit by a shell and then collapsed in the explosion. He muttered some words that only he could hear and staggered on his feet.
It was as if he had lost his soul.
There were more soldiers who were frightened out of their wits by the sight before them. Some of them even dared to kneel on the ground and kept begging for mercy, praying to the gods to forgive themselves.
However, it was obvious that no one could hear their prayers. The three artillery battalions more than ten kilometers away were continuing to load and fire at this moment, with no intention of stopping.
The entire city has been shrouded in artillery fire, and some city walls were directly hit by artillery shells and collapsed into fragments of ruins.
The ground was shaking, and as soon as the cry started to sound, it was suppressed by the explosion. The whole city seemed to be destroyed, and there were scenes like hell everywhere.
Back then, the soldiers of the Arrant Empire could only hold out for a short time under the attack of the old-fashioned artillery of the Airanthil Empire. Now these poor people from the Rock Empire are facing 155mm caliber howitzers that are no longer what they used to be.
, naturally collapses faster.
A shell roared into the Crusader camp, and the explosion blew away several tents. The Crusader soldiers who were singing and dancing to celebrate their victory one moment were flying into the sky the next second.
