Yang Shiyilang: What is wet mixing method, what is granular medicine, and what is maroon medicine.
Beautiful girl with Chinese style: Sajia will explain it to you.
A detailed document was then sent.
Yang Fan took it in, opened it and saw that it was like this.
A sudden realization.
Yang Shiyilang: What are the benefits of granular medicine?
National style beauty girl: stable, well combined, and will not fail due to vibration during transportation.
Powdered medicine is easily squeezed together when it is stressed in the barrel. In this way, it will not burn completely due to lack of oxygen during ignition. A lot of unburned medicine will be sprayed out of the barrel along with the bullet. This reduces the power of the medicine and is wasteful.
Seriously, it raises military costs.
In order to solve this problem, early gunners would avoid filling the medicine too tightly, but it would not work too loosely, because this would also reduce the power of the medicine.
The best operation is to deliberately not fill the gun chamber too full or too tightly when loading the gun. However, although this can bring out the power of the gun, it requires a high level of experience and skill on the part of the gunman and is difficult for ordinary people to learn.
The granular medicine has large gaps, sufficient oxygen, and complete combustion. The combustion lasts well, and the energy output is stable and it is not easy to explode.
Emperor Sauron: Later, with the advancement of medicine, the gun could be made longer and its range increased.
The British conducted experiments and used a formula from the late 13th century. The medicine was prepared using dry mixing methods and wet mixing methods, and the bullets were divided into lead bullets and steel bullets (used as armor-piercing bullets in the late Middle Ages).
The shooting target is a 2.54 mm mild steel plate, and the shooting distance is 9.1 meters. The misfire of the powder mixed with dry powder is quite high, a quarter of the misfire.
The misfire rate of the medicine made by wetting and stirring is extremely low. The wet mixed medicine performs more reliably. In the test, the misfire rate is less than 10%, and the burning rate is faster, and the muzzle velocity is higher.
During the test, the muzzle velocity of the lead bullet fluctuated greatly, which may be caused by the irregular shape of the lead bullet. In the test, it was found that the fire door gun was fairly accurate at a distance of 9.1 meters, but it was not clear beyond this distance.
The muzzle velocity of the 15-inch portal gun representing the late 15th century portal gun is 50% higher than the 5-inch portal gun representing the 14th century portal gun. This is mainly due to the advancement of gunpowder.
Moreover, the 5-inch fire door gun hit the steel plate 5 times, but none of them penetrated the steel plate. The 10-inch fire door gun hit the steel plate 14 times, and only 6 times penetrated the steel plate. The 15-inch fire door gun hit the steel plate 8 times, and 5 of them penetrated.
Pierced the steel plate.
In other words, the front loaded shell of your nine-section repeating gun must be no less than 381 mm away from the muzzle to ensure its power. And the distance of use should not exceed ten meters, otherwise you will not know where it hit.
Yang Shiyilang: I understand, so my design is a failure.
Emperor Sauron: Not necessarily. I think your design still has great value, but it’s just wrongly positioned and used in the wrong situation.
When the first infantry is fighting at close range, the accurate range of the nine-section repeating gun exceeds the length of a spear, and the continuous and powerful firepower is still of great value.
It is recommended that you install a handguard and butt on this gun. Use it simply as a rifle. When shooting with the butt on your shoulder, your other hand can be freed to light the gun. And it is not hot to touch with the handguard.
In addition, this kind of gunner needs sword and shield soldiers to cover in the front. He fires from behind, so the effect is better. A third row of spear soldiers can also be added.
As he said this, he sent a picture, which was an exploded view of the 98k rifle.
You see, just use the wooden part of this modern rifle. The design is very reasonable and has reached perfection. There is no need to use those weird ancient designs. You can use iron buckles to fix the one-meter-long barrel on it.
It can even be designed to quickly replace the barrel. Normally, the shooter carries a loaded barrel on his back and quickly replaces it after firing. 18 rounds are enough for a fight. No reloading is required.
It is specially used for the battle between two armies, when the cold weapons are in hand-to-hand combat, and it is specially used for queuing up and shooting within ten meters.
Yang Shiyilang: Got it. Thank you all. I have another question, why can't the fire door gun deal with bows and arrows?
Pharaoh's slipper-bearing officer: You must first understand that there is a difference between a bow and a crossbow. Although they are both tools for shooting arrows, their usage is completely different.
Bows are most commonly used as curved-fire weapons. Crossbows are most commonly used as direct-fire weapons. Just like howitzers and tank guns.
Although the fire portal gun is powerful at close range, the range is a problem. The heavy steel crossbow of the 15th century can shoot the crossbow bolt 380 yards (1 yard is about 0.91 meters) at an elevation angle of 45 degrees, and the range can reach 70 yards (63 meters) when firing flatly.
).
Because the crossbow is mainly used for horizontal shooting, the range disadvantage of the long-barreled door gun using high-efficiency gunpowder is not obvious, but it pales in comparison to the British longbow. The range of a 100-pound longbow is about 250 yards.
The 160 pound longbow can even shoot up to 350 yards.
Moreover, the shape of the lead bullet causes the bullets fired by the fire door gun to attenuate significantly in speed, which means that when shooting at long-distance targets, the power of the fire door gun will be greatly reduced. In addition, the loading process of the fire door gun is troublesome and difficult to shoot.
Slow speed.
Compared with the above problems, the poor accuracy of the fire gate gun is not important. On the battlefield, the fire gate gunner faces enemies in a dense formation. It is far easier to hit these targets than to shoot a single enemy.
.This is also the reason why the early fire gate guns were only rarely equipped by the army despite their poor actual power.
Yang Shiyilang: Then why did the matchlock eventually eliminate the crossbow?
The beautiful girl of the Medici family: That’s because the barrel of the matchlock is forged, and the barrel of the gun is drilled with a steel drill and carefully polished and bored. At the same time, gunpowder technology has also improved. The barrel has been greatly lengthened.
The bullet travel was increased, allowing the shooting range to reach about 80 meters. Beyond the direct shooting distance of the crossbow, the crossbow was first eliminated. Then the rifled gun appeared, eliminating the bow in terms of shooting range.
Fat Tiger: Your design is actually good. It is very useful for supporting soldiers in melee combat at close range. It has strong firepower and fast firing speed. It can even deal with cavalry within thirty meters. Rapid ignition in sequence is enough to finish the fight.
Five rounds of lead bullets. And it is enough to penetrate iron armor at close range, and it is no problem to kill a horse at a distance.
Yang Fan closed the notebook with satisfaction.
His confusion became clear.
Tomorrow he will find the fifty carpenters he brought with him to make the gun butt.
Change the nine-section repeating gun into a rifle style.
At the same time, a large wooden shield was made and equipped with one hundred and fifty sets of captured armor and long knives.
Then put the gun head on a long wooden pole and stab it with Jiannu.
Those magic guns that have been made cannot be discarded. These are all silver. You can let the soldiers carry an extra bracket, which can at least make up for it.
Yang Fan felt relieved and fell into a deep sleep.
