The artillery on the mountain opened fire, and eighteen twelve-pounders opened fire one after another.
This is a new type of front-loaded, smooth-bore artillery that uses cylindrical explosive bombs.
Normally in this era, cannonballs are spherical and solid.
Explosive ammunition has appeared, but due to the power of black powder, the effect is very poor.
If the artillery shell is made into a cylindrical shape, it involves the strength of the shell of the artillery shell under the bore pressure.
Because the spherical solid bullet is solid, it has its own compression properties.
Cylindrical projectiles are hollow and require the outer wall of the projectile to resist pressure.
If the cannon shell is not thick enough, it will be crushed, and it is likely that the bullet will jam and cause the chamber to explode. If the shell is made of steel and the thickness increases, the black powder loaded inside is not powerful enough, and whether it can explode is a problem.
In the movie, when the shells of the Beiyang Navy were disassembled, they were filled with sand and no gunpowder. We were filled with indignation at the time, thinking that the Qing government was corrupt and incompetent and had been deceived by foreigners.
In fact, we didn't understand. At that time, armor-piercing bullets were solid and mainly filled with sand and gravel. Because the explosive power of black powder was not good, it was better to increase the weight of the warhead for armor-piercing.
The end of the 19th century was the last period for black powder to be used as explosives and propellants for artillery shells. Explosives were on the eve of change. The 1880s and 1990s were precisely the era of revolutionary progress in the world's navies and artillery. Things that were useful yesterday could no longer be used in the blink of an eye.
will fall behind.
In the 1880s, there were still many artillery shells loaded with counterweights, especially armor-piercing shells. They would not explode. They were normal artillery shells. The biggest reason for the destruction of the Beiyang Fleet was that the navy was a continuously developing arm. The Qing government
After the Beiyang Navy formed an army, it was unwilling to continue spending money on upgrades.
This results in the Beiyang Fleet's artillery shells being retractable artillery with a slow firing rate. The shells use black powder and have poor explosive power. Many armor-piercing projectile warheads are filled with sand and gravel weights and have no explosive power, so they can only be drilled out. This is also
We saw the reason why there were so many holes in the little devil's ship after the war.
A large number of the Japanese combined fleet's secondary guns were replaced with the latest six-inch tube-retractable 152 naval guns, and the shells were loaded with Haze powder (picric acid explosive technology stolen from France.)
During the Sino-Japanese War of 1884-1898, the biggest disadvantage suffered by the Beiyang Navy was the lack of rapid-fire guns. Compared with the Japanese ships' total of 67 perfect rapid-fire guns, the Beiyang Navy only had six early-type 35x120mm Krupp rapid-fire guns.
The difference between the two rates of fire is 25 times. The explosion power of black powder and picric acid explosives is 75 times different!!!
This is the fundamental reason for defeat.
In fact, the Japs had no advantage in training. The Beiyang Navy's hit rate was over four percent, while theirs was only a few points. The main reason was that the court did not provide money for upgrades, which resulted in all equipment being eliminated at the critical moment.
Yang Fan's twelve-pounder field gun is the largest caliber field gun commonly used in this era.
It was the same in Europe, and it remained the same for the next two hundred years.
No matter how large the caliber is, it is too heavy to be towed and followed by the army.
Artillery that cannot be used on the battlefield is meaningless no matter how powerful it is.
Because Yang Fan has good explosives, he can make the casing of the high-pressure artillery shell strong. Only then can the cylindrical hollow artillery shell be born. This kind of artillery shell is not filled with explosives inside, and the explosive is not stressed, and the projectile body is the one that bears the force.
Powerful.
Modern 122mm artillery shells have a charge of 3.5 kilograms, which is about 7.72 pounds. Even though the cylindrical artillery shell is front-loaded, it weighs about 22 kilograms, which is about 48 pounds.
The reason why the weight of the projectile increases significantly under the same aperture is because the shape of the spherical solid projectile limits the weight of the projectile. Similarly, because the propellant is still maroon gunpowder, the range is only 900 meters.
The cylindrical shells allowed the twelve-pound front-loading smoothbore cannon to fire heavy shells close to fifty pounds, which were also explosive shells. This improvement is still very considerable.
However, this kind of artillery shell can only kill enemy troops with shrapnel, but cannot cause ricochet to pass through the enemy's dense infantry formation like spherical shells.
The 7 pounds of chemical fertilizer and sugar explosives loaded inside are powerful enough to reach more than 70% of modern artillery shells.
Eighteen rounds of artillery shells quickly fell on the opponent's artillery position.
Eighteen fireballs rose up and shrapnel flew across the sky. However, none of them hit, and they all landed in front of and behind the lined-up artillery positions.
"Master, I didn't hit it." Xiao Niangpi said in frustration.
"Yes, it's normal to miss. This is a non-direct-aim shot. The trajectory is parabolic. You need to use a logarithmic table to calculate the trajectory. You also need to consider the impact of the crosswind. As long as you can hit a cross-fire in the first round.
Already."
Chen Xi understood, the young talented girl is a mathematical genius.
"Madam, this method of shooting is indirect aiming, which is not as accurate as direct shooting at close range, but it can hit long-distance targets. With the development of technology in the future, the shells will definitely hit farther and farther, and the human eye cannot see it.
Target shooting will be rare in the future. This method of shooting is a great advancement in artillery technology." Chen Xi continued to explain.
Eighteen fireballs exploded on the battlefield, frightening the Heshuote people.
They have never seen explosive ammunition. This thing was just invented in Europe not long ago, and its power is very poor and it is very niche.
More than a dozen cavalrymen who were responsible for guarding and protecting the artillery positions outside were hit by shrapnel and fell off their horses.
Orchitukhan was shocked and turned to ask Orhan Bey, a technician hired by the Ottoman Empire.
"What kind of weapon is this and why is it so powerful?"
Bey was also horrified. He knew that there were explosive bombs in Europe. But he didn't know what the Ming Dynasty's firearms technology was. But an explosion of this scale would be too shocking.
There was a huge noise, a rising fireball, and flying shrapnel.
"This should be a bomb, but how could a bomb be so powerful?" He widened his eyes in disbelief.
Then the second round of artillery shells roared and fell on the position.
Boom boom boom! This time, three artillery shells hit the position. The artillery bombers were immediately knocked off their backs.
Each of their cannons was about fifteen meters away. The middle and sides were piled with wooden barrels of propellant and piles of spherical solid bullets.
This chapter is not over, please click on the next page to continue reading! The propellant barrels are densely stacked. They do not have modern safety awareness.
Because no explosive ammunition was used in actual combat in this era, there was no need to worry about the gunpowder being detonated.
The only person who really did this was Gustav II of Sweden. He used red-hot iron balls as cannonballs to attack the Russian artillery positions.
As a result, the piled gunpowder detonated and all the Russian artillery positions were destroyed.
There was a loud noise, and a cannonball hit the spot where hundreds of powder barrels were piled. The entire propellant pile was detonated.
The propellant formulas of matchlocks and artillery are different. The propellant of guns accounts for 75% of nitrate, while the propellant of artillery accounts for 78% of nitrate. Therefore, the propellant of guns explodes faster and has a larger shock wave. The surrounding areas
Were all the people and horses swept away, they were blown up into the air?
The explosion of tens of thousands of kilograms of black powder at the same time is also very shocking.
A black mushroom cloud rose and a huge fireball rose into the sky.
The red and black substances inside the fireball alternated and rolled, eventually turning into huge smoke that stayed in the air.
All six twelve-pound cannons were blown away by the huge explosion. Some barrels were shattered, and some flew into the sky and smashed down. The bronze was relatively soft, and it twisted and deformed after landing, and was directly scrapped.
The surrounding artillery and a dozen technicians from the Ottomans were all killed.
The entire artillery position was in a mess.
The huge explosion caused the ground to shake and many people fell to the ground.
Many people's ears were temporarily deafened and bleeding. They could not hear any sounds and could only watch the people around them running around and shouting.
Yang Fan's wives were all shocked. They opened their mouths and were speechless.
This is too scary. They have never seen an explosion of this scale.
Even though they were more than a kilometer apart, I still felt the shock wave fly past my cheek.
