Huang Hansheng and Yang Youji looked at each other, the guys made by the old man, one is more powerful than the other, in front of the power of guns, knives, guns, bows and arrows are so vulnerable. Pen % fun % Pavilion www.biquge.info

After the howitzer was successfully fired, Lin Weiye let out a "yes" and clenched his fists in celebration. Although it did not hit the intended target, the cannon was successfully fired, and the power was about the same as expected, which gave him confidence in the first time when he cast the cannon.

Xia Nan personally ran over to check, and the solid bullets smashed several craters on the ground, and the hard ground was smashed and dirt and stones were splashed everywhere. This is going to be smashed on people, how can flesh and blood stop it? He trotted back: "Congratulations viagra congratulations viagra, the artillery test shot was successful!" ”

Lin Weiye said: "Don't worry, I'll have another shot, and it will be perfect if I hit the target." ”

He instructed the people to reset the cannon, briefly calculated the angle and direction of the muzzle, adjusted it, and reloaded and fired again. This time the shells accurately concentrated the mound, and the entire mound was blown into a flying clod, and the scene was spectacular.

The two of them said "yes" at the same time and high-fived in celebration. Test firing showed that at about three hundred meters, the accuracy of this gun was considerable. Lin Weiye changed to another gun, and after gaining experience, the first gun hit the target, which shows that the quality of both guns is very good.

With a little pride, Lin Weiye announced: "The 12-pound mountain howitzer was successfully tested with a solid bullet!" ”

Xia Nan couldn't wait to drag the cannon back to the escort team for practice, but Lin Weiye stopped him, "Don't worry, this is just the first step." Next, in addition to making the gun carriage and the front trailer to fix the gun body, there are still a few small details to be perfected, and after these steps are completed, the rate of fire and accuracy of the entire gun will be raised to a higher level. ”

"The cannons in the movie are all stuffed with iron balls and ignited directly, how can you have so much trouble." In the summer, Nan's heart is itching.

"Although the technology of front-loading smoothbore guns is relatively simple, there is still a lot of room for improvement, and these technologies are the crystallization of the wisdom of predecessors for two or three centuries. Besides, this time it was only a solid bullet fired, do you want a grenade, that is, a hollow explosive bomb? ”

In the summer, Nan Daxi, it is called a cannon when an explosive bomb is fired, and the solid iron ball seems to be a little bit worse: "That's a must, get a few explosive bombs, Lao Tzu wants to use it to blow up the wooden village of Chopping Feet!" ”

The few improvements mentioned by Lin Weiye are the 19th-century perfected technologies such as wooden cartridge stocks, improved grenades, and fixed-mounted artillery shells. These technologies have both conceptual leaps and technological advances. These improvements made solid shells no longer the only option for smoothbore guns, and grenades began to shine.

Grenades, also known as explosive bombs, are caused by fragments of the shell after the explosion of gunpowder. In the early days, due to the material, the inner wall of the cartridge case could not be too thin to withstand the chamber pressure generated by the gunpowder in the enclosed space of the barrel, or it would explode in the barrel. However, if the inner wall is thick and the charge is too small, it will form a stew explosion, and it will not be able to explode the shell to cause damage. The grenade created after such a compromise has a small charge, and the power of black powder is enough to choke, resulting in very few fragments after explosion, and the lethality is very limited.

In actual combat, the spherical grenade is ignited by the powder twist, and the grenade is divided into two steps: igniting the powder twist and igniting the fire rope at the end of the gun, the operation is complex and dangerous, the powder twist fuse must be placed in the direction of the muzzle, otherwise the fuse is ignited in advance, it is the end of the cannon destruction and death, and in the fierce battle, the shell is placed in the wrong direction is a common thing. So until the 18th century, cannon + solid cartridge was the mainstream of the battlefield, and howitzers were a supporting role for a long time, until the advent of wooden cartridges and wooden conical letter tubes.

The improved grenade is actually a grenade made by combining the two technologies of wooden butt + wooden conical letter tube.

The so-called wooden bullet butt is a wooden pallet similar to a tray mounted on the spherical bullet body, and tied and fixed with cloth strips. In addition to effectively sealing and preventing gas leakage, the center of gravity of the whole shell will be forward due to the light wooden support (the density of iron is greater than that of wood), which makes the cannonball appear to be heavy at the head and light tail after the cannonball, and the flight trajectory is extremely stable, the trajectory is more accurate, and the firing range is longer.

The technology of the wooden conical letter tube is very simple, that is, the hollow conical wooden stopper, the wooden plug hole is loaded with gunpowder, the letter tube is plugged from the ignition hole of the hollow shell, slightly higher than the surface of the sphere, when fired, because there is a certain clearance between the smoothbore gun and the shell, the high temperature of gunpowder burning will pass through the gap between the shell and the gun wall, igniting the front of the letter tube, which not only saves the trouble of igniting the shell fuse and firing the gunpowder bag at the same time, but also avoids the danger caused by misoperation.

In the 19th century, when the casting technology progressed, people combined the wooden cartridge stock with the wooden conical letter tube to obtain an improved type of grenade, and the previous drawbacks were solved one by one, and the grenade began to shine. The wooden cartridge originally used for solid bullets, after being installed on the grenade, not only plays the role of enhancing the air tightness and ballistic accuracy of the solid bullet, but also plays a buffering role, so that the grenade will not explode under high bore pressure, and more importantly, the fuse is installed in the opposite direction of the wooden cartridge butt, so that the fuse will not be turned down when loading, and the operation error will be avoided.

The fixed artillery shell is a further improvement on the basis of the previous one. Traditional artillery firing needs to determine the amount of gunpowder with a measuring tool or experience, and it is easy to blow up the chamber if there are fewer shells. The artillery of the 17th century required an experienced gunner to operate, and it was not something that could be played by just anyone. The fixed artillery shells that appeared in the 19th century are based on the wooden cartridge butt, the gunpowder required for firing is packed into a package, and the shell, the cartridge stock, and the cartridge are fixed into a whole, and the fixed shell is ignited as long as it is stuffed into the fixed shell when fired, without the need for a complex charging process, and a soldier can operate it after simple training. As a result, the rate of fire of the artillery increased significantly.

These improvements, on the premise that the performance of the gun remains the same, increase the firing range, improve the accuracy and rate of fire, and it is not technically difficult to achieve. Lin Weiye is now all applied to his own artillery, plus the improvement of casting materials, compared with the artillery of the same era, there is almost an advantage of generational difference.

Lin Weiye was not satisfied with these, he once again sacrificed the magic weapon of graphitization annealing and applied it to hollow grenades. In the early grenades, the shells were all white iron, which could easily explode under high bore pressure, and thickening the inner wall would reduce the power. Now, by simmering the cannon barrel and simmering the cast hollow grenade shell to increase the strength of the projectile body, you can make the inner wall thinner and fill more gunpowder. This greatly increases the power of the grenade until there is no better gunpowder.
