Chapter 418 The shape of the warhead is also important

Therefore, the bronze caliper can be regarded as a major invention in the history of China.

However, according to page 10 of Volume 402 of the Western Encyclopedia published in 9, it is claimed that the vernier caliper was invented by Western mathematician Venier Peel in [-] AD.And our country has been using it as early as AD [-], so Western encyclopedias should be rewritten.

Facts have proved that the invention and use of the vernier caliper in China was at least about 700 years earlier than that in the West, and until today, the caliper has generally remained the same as when Wang Mang invented it.Therefore, the inventions of the ancient Chinese once again rewrote the history of the world.

In fact, the reason why Bailixiu used the vernier caliper was mainly to see the difference between the vernier caliper of the Ming Dynasty and the modern vernier caliper. However, it turns out that there is actually no difference at all.

After all, with Bailixiu's talent for super precision, even without the use of vernier calipers, it can be processed to perfection.

So when Bai Lixiu took the gunpowder barrel processed by the machine tool and stuffed it perfectly into the back hall of the fire gun, the two blacksmiths immediately sighed that the machine tool can still be used like this.

After another test firing, the seal between the gun barrel coming out of the machine tool and the gunpowder barrel, that is, the all-metal shell case, was finally in place and no smoke was coming out.

Although the power has increased a lot, it can shoot through the target, but its accuracy has not increased much. It is not bad within a hundred meters, but it depends on God's will beyond a hundred meters.

It doesn't have much distance from the shooting distance of bows and arrows.

The reason for this is not that the power is insufficient, but because there is no rifling, and the two blacksmiths still use spherical lead bullets instead of cylindrical lead bullets.

When it comes to cylindrical lead bullets, we have to talk about the Minie bullets that were invented in [-].

Because of its cylindrical bullet diameter slightly smaller than the diameter of the gun bore, Mini bullets are easy to load.There is a conical cavity at the bottom of the bullet, and a cork blocks the bottom of the hole. When firing, the gas presses the cork into the cavity, forcing the bottom of the bullet to expand, close to the rifling, and close the gap between the bullet and the chamber, allowing the gas to It cannot be leaked out, and the warhead can be rotated at high speed under the pressure of the rifling.Minie bullets solved the problem of difficulty in loading front-loading rifled guns and the low range accuracy of smoothbore guns, making rifles surpass artillery and became the decisive weapon on the battlefield at that time.

In fact, it was on the battlefield in the east that made the mini bombs shine.

In [-], the Taiping Heavenly Kingdom initiated by Hong Xiuquan launched an armed uprising against the Manchu Qing court in Jintian. It took them only two years to take down half of the Manchu Qing Dynasty and set up their capital in Jinling.

But what made the Taiping Heavenly Kingdom so brave?Whenever he confronted the Qing soldiers, he was able to defeat the Qing soldiers that were several times his own.It turned out that the Taiping Heavenly Kingdom purchased a batch of muskets from Western countries, and they were muskets that fired "mini bombs".This kind of "Mini bomb", which is also the most cutting-edge in Europe, has shown its power in the ancient East.

At that time, the soldiers of the Qing Dynasty still used cold weapons to attack the Taiping Heavenly Kingdom. As a result, they were beaten by the soldiers of the Taiping Heavenly Kingdom with muskets filled with "Mini bullets".Even the attack launched by the cavalry, which the Manchus were proud of, was tantamount to suicide, because most of the cavalry and horses had been hit by the "Mini bullets" before the cavalry approached the infantry. If you don't need it, the bow and arrow for long-range attack is even worse, because the range of the bow and arrow is about 70 meters, while the range of the "mini bomb" is a terrifying 500 meters or more!

Although the peasant uprising was eventually defeated due to the internal friction of the Taiping Heavenly Kingdom, which made people sad, the power of the "Mini bomb" shocked the world.After the Taiping Heavenly Kingdom was wiped out, the Manchu and Qing courts, which were still standing still, began to customize modern hot weapons to Western countries for the first time.It can be seen how much impact the "Mini bomb" had on the Manchu court.

At that time, Western muskets were still front-loading ammunition, and the metal fixed-loading ammunition for rear loading still did not appear, and the barrel had already appeared rifling that could make bullets hit more accurately.But it has brought a new trouble to the soldiers, that is, it is very troublesome to fill the bullets every time, because if you want the bullets to hit more accurately and farther, you have to let the bullets fill the barrel without leaving any gaps. .This made loading projectiles so cumbersome that each soldier had to be issued a small hammer to hammer the cleaning rod to load the projectile into the barrel while loading the bullets.

The style of the "Mini bullet" is almost the same as that of modern bullets. They are all cylindrical cones, which are slightly smaller than the barrel, which makes it easier to fill. .When the gunpowder is activated, the gas presses the cork into the groove, forcing the bottom of the bullet to expand, close to the rifling, and close the gap between the bullet and the barrel, so that the gas cannot leak out, and the bullet can be pressed under the pressure of the rifle. Spin at high speed.The range of this "Mini bomb" can reach more than 400 meters. His appearance completely changed the strategy and tactics of the West at that time.

In the era of Napoleon, the effective range of flintlock guns was less than 100 meters. At that time, the big killer on the battlefield was artillery. The front line of the infantry retreated to the rear of the infantry and became an auxiliary weapon, because the range of the artillery at that time was less than 400 meters.

Of course, the inspiration of the Mini bomb was quickly applied to the artillery, and the original spherical artillery gradually began to develop into a cylindrical cone.

All of a sudden, the range of the artillery has reached more than ten kilometers.

Of course, Minnie bombs the muskets in the front hall, and the artillery is an artifact, but it seems that it is not so important when it comes to the metal installation period in the back hall.

After all, compared with the front-loading hall, the post-loading hall has a long process of plugging the barrel. However, since the appearance of the Minie bullet, even modern bullets have not used spherical bullets, basically cylindrical bullets. Shaped with a tapered bullet tip, or an oval bullet tip, and even if the bottom of the bullet is not concave like the Mini bullet, it is flat-bottomed and will not bulge like a spherical bullet.

Of course, even though Bailixiu knew the reason why the lead bullets would not hit a hundred meters away, but Bailixiu did not directly launch the rifling and the Minnie bullets, but instead asked Prince Zhu Biao:

"The lead bullet is not accurate at a distance of [-] meters. Although it is still very powerful, if the landing point is not accurate, there is no way to hit the enemy. I don't know if His Royal Highness has not thought of any way to increase the accuracy of the lead bullet. What is the degree?"

When Prince Zhu Biao heard Bai Lixiu's question, he didn't need to think too much, and he obviously understood that it was Bai Lixiu who was questioning him again.

But the invention or discovery of this thing is not immediately thought of. It is said that the person who invented the rifling to make the bullet rotate to increase the stability was actually inspired by the spinning top.

Because when the gyro rotates, it can stand up steadily immediately, so the bullet thought that if the bullet was rotated, would it be possible to keep it from flying around?
