Chapter 317 Artillery Upgrade 2

Later, after thinking for a long time, he suddenly didn't know which muscle in his mind, which flashed and reminded him of the historical Americans (he doesn't remember the name of this person, this person should be Rodman) once invented the internal mold water cooling technology, so that when casting the gun barrel The cooling and solidification speed of the wall exceeds the cooling speed of the outer wall, which forms a stronger layer of steel on the inner wall, which greatly improves the robustness of the artillery. At the same time, it also greatly improves the yield, and even makes the scrap rate basically zero.

In fact, the water cooling technology of the inner mold is very simple, that is, when making the inner mold of the gun barrel, the inner mold is made into a hollow structure, with a water inlet and a water outlet, which continuously injects cold water from the inlet and flows out of the outlet, so that the inner mold of the gun barrel can quickly cool down and absorb the heat inside the casting. It is actually a self-tightening process that makes the surface of the casting close to the inner mold solidify and cool faster.

So Yu Xiaotian said he would do it, and immediately asked the craftsman to transform the inner mold of the artillery, and changed from a new hollow inner mold to water cooling technology to cast the cannon.

In this way, after the test, the quality of the newly cast artillery is much higher than that of the cannon cast by the ordinary iron casting method. During the destructive test, the amount of charge cast by the new internal mold water cooling technology has increased by nearly 40% compared with the previous cannon. In this way, the artillery can be loaded with more * without increasing weight, so that the shell can obtain a higher muzz speed and a larger range and higher accuracy.

However, it is impossible to blindly increase the loading amount of gunpowder, because in theory, the best loading amount of artillery is not the better. Some studies believe that the loading amount of artillery is best * after full combustion, and the energy generated is just enough to push the cannonball out of the chamber.

If the amount of charge is too much, the gunpowder will fly out of the muzzle before it is fully exploded, which will waste the gunpowder. No matter how much it is installed, it may not increase the muzzle velocity and power. However, if the charge is too little, after the gunpowder explosion is completed, the shell has not yet flown out of the muzzle, which will make the cannonball and the gunpow. Rub, generate resistance, reduce the range and power of the gun and affect the accuracy of the gun.

At this point, Westerners have come to the forefront. When they use artillery, they have understood this truth. At the same time, through the study of mathematics, they have made a cannon table, so that as long as the gunner looks at the cannon table, it is very convenient to know how far to hit the target and use solid bullets or howitzers. How much gunpowder should be filled, so that the shelling can be more accurate.

However, as a Chinese who invented artillery, because no one has ever paid attention to this problem and has not formed a systematic research, the gunner, that is also a blacksmith, is stingy with their craftsmanship, for fear that others will learn their skills and rob them of their jobs, so they never communicate with each other, but only from generation to generation. It is so that since the invention of the artillery, China's overall technology has improved very slowly. Even at the end of the Ming Dynasty, China's self-made artillery did not even have anything to aim at. It all depends on the experience of the gunner to estimate and aim. The accuracy of this cannon can be imagined.

However, Westerners, who, on the other hand, as students, gradually formed a set of strict technical specifications during the use of artillery. In a short period of time, they were cast into artillery far more than those cast by the Chinese. In turn, the Chinese had to learn the technology of casting cannons from Westerners. , buy cannons from Westerners and invite former students to teach them their skills.

This kind of thing makes many Chinese feel a little depressed when they think about it, but they have to admit that Yu Xiaotian is certainly one of them. If he hadn't traveled to this era and learned a lot about the cannon casting technology invented by later generations, I'm afraid he wouldn't have made such a good cannon.

The newly cast 12-pound short gun is cast with a new internal mold water-cooled technology. Under the premise of ensuring the strength of the gun body tube, the thickness of the gun wall is reduced again, so that the weight of the gun body can be reduced. This gun can be installed on two gun racks when installed on four-wheel gun racks. , can be used as a naval gun and put on the ship. Even if it was a light ship that used to only carry six-pound guns, now it can also be loaded with new 12-pound short guns. In this way, once a large area of warships are equipped with sea wolves, the firepower of sea wolves can be increased by one level.

If it is installed on a two-wheel gun rack, the total weight of this kind of gun is less than 300 kg, that is less than 600 kg. A horse can pull and follow the soldiers to maneuver on the battlefield, so that the soldiers can gain stronger attack ability.

Even in mountain warfare, it is impossible to use animal power to haul artillery. If necessary, you can disassemble the gun racks, decompose the barrel and gun racks, carry them with mules and horses to act in the mountains, which is the strongest firepower that sea wolf soldiers can obtain so far.

Even if the sea wolf has a serious lack of animal power and is not very difficult to march on short-distance terrain, they can completely adopt the method of subrogate animal pawns and rely on manpower to pull artillery to follow the team to ensure that soldiers can obtain more effective fire support and fire suppression and attack under ordinary circumstances. Strong ability.

At present, the newly minted 12-pound mountain howitzer has undoubtedly become a product of the super era, greatly improving the firepower strength of the sea wolf division and soldiers.

After the successful trial production of this short-tube 12-pound howitzer, it immediately began to replace the production of the six-pound gun and became the focus of the recent production of Sea Wolf cannon. In a short period of time, dozens of them were built and equipped among marines and soldiers, and the marines naturally obtained most of them and assigned some ships. Above, the firepower of the warship has been improved.

In addition, through various ways, the sea wolf has basically solved the problem ofxiao shi supply. Not only has a large number of saltpeter and sulfur been stored, but also the two gunpowder workshops in fresh water and Nanri Island have also recently produced a lot of gunpowder. In addition, the sea wolf's gunpowder workshops have been insisting on producing grained gunpowder, making the sea wolf's gunpowder The quality has always been ahead of its peers and officers and soldiers. Even the gunpowder of Western countries can reach the current level of gunpowder produced by sea wolves at most.

So the sea wolf is not afraid of the government cutting off the supply of their supplies. Now, after a year or two, although the grain output on Nanri Island is not high, it can basically meet the needs of the people on the island and the sea wolves. Fresh water and chicken cages have not yet reached the level of self-producing. However, after more than a year of operation, the self-sufficiency capacity of grain can now meet about 70% of the demand, and the remaining 30% of the demand can be purchased from land.

Recently, after the rice matured, the sea wolf took out a considerable amount of funds and purchased hundreds of thousands of catties of grain from Guangdong and Fujian, so that recently raised the price of grain in Fujian and Guangdong. Now the sea wolf has begun to go to Guangxi. Run over there and buy a large amount of grain there.

As the saying goes, he has food in his hand and does not panic. Yu Xiaotian knows the importance of food for the survival of sea wolves. Once there is a natural disaster on land, there will be a large-scale famine. At that time, the grain he reserves in advance can take the opportunity to attract many disaster victims and follow him to Taiwan Island to make a living. This is the key to population explosion.

In addition, fresh water and chicken cages now have more and more people, but the land reclaimed is still a place of land. In addition, Taiwan has a lot of precipitation. At present, farmland drainage and irrigation facilities are not complete, and it is easy to be flooded. Once there is a flood, immigrants may have no harvest. He can't say that he doesn't care about it and watch it. Some immigrants starve to death, so it is necessary to store food in advance and need it from time to time.

Therefore, although the sea wolf's income is getting higher and higher, the expenditure is also getting bigger and bigger. No matter how much money is stored, it is not effective to store more food and various materials. Therefore, the people of the board of the board are very dissatisfied with such a generous amount of money as Xiaotian. Their left hand and out, so that the board of directors have never saved much money.

If the board of directors hadn't taken into account the reserve of enough money and rewards for the sea wolf department, it is estimated that Yu Xiaotian would have spent all the money of the council hall.

However, the benefits are also obvious. The sea wolf has sufficient food and various materials and weapons in their hands, so that they can live a peaceful life and don't have to worry about eating this meal.

So this time to deal with the advance and suppressing action of the officers and soldiers, the sea wolf, especially these leaders, were full of confidence and even a little rubbing their hands. Just waiting for Xiaotian's order, they took turns to fight.

The current Nanrishui Village is located in the southern prok of Puxi, Zhongmen Peninsula, which is only a few miles away from Meizhou Island across the sea.

This is also the gateway to Xinghuafu. To the north is Pinghai Bay, which belongs to Xinghuafu. Puxi Qianhu and Pinghaiwei just guard Pinghai Bay, close to the Nanri Waterway, across the sea from Nanri Island, and only more than 30 miles away.

Recently, because the governor of Fujian wanted to use troops on Nanri Island, he sealed ships along the coast of Fujian and banned merchant ships from entering the sea, which made the Nanri Waterway, which is usually busy with shipping, much deserted.

And because the officers and soldiers began to station in Pinghaiwei and Puxi, warships also began to gather in Pinghai Bay and Xinghua Bay, which made the situation around Xinghuafu much more tense. Even some fishermen were banned from going to sea. The government's statement was to prevent fishermen from thieves.
