Later, after thinking about it for a long time, suddenly something in his mind moved, and he had a flash of inspiration, remembering the American in history (he couldn't remember the name of this person, this person should be called

Rodman once invented the internal mold water cooling technology, which allowed the inner wall of the barrel to cool and solidify faster than the outer wall when casting the gun, forming a layer of stronger steel on the inner wall, which greatly improved the sturdiness of the gun.

At the same time, it also greatly improved the yield rate and even brought the scrap rate to basically zero.

In fact, the internal mold water cooling technology is very simple. When making the inner mold of the cannon barrel, the inner mold is made into a hollow structure with a water inlet and a water outlet. Cold water is continuously injected from the water inlet and from the water outlet.

The flow out allows the inner mold of the barrel to cool down quickly, absorbing the heat inside the casting, so that the surface of the casting close to the inner mold solidifies and cools faster. In fact, it is a self-tightening process for the barrel.

So Yu Xiaotian went ahead and immediately asked the artillery craftsmen to modify the inner mold of the artillery, cast a new hollow inner mold, and use water-cooling technology to cast the artillery.

As a result, after the test, the quality of the newly cast cannons was greatly improved compared to the previous cannons cast by the ordinary iron mold casting method. When conducting destructive tests, new internal mold water cooling technology was used.

The amount of powder that the cast iron cannon can withstand has increased by nearly 40% compared to previous cannons. In this way, the artillery can be loaded with more propellant without increasing its weight, making the shells more effective.

High muzzle velocity results in greater range and higher accuracy.

However, it is impossible for artillery to blindly increase the loading of gunpowder, because in theory, the optimal loading of artillery is not more, the better. Some studies believe that the best loading of artillery is after the propellant has been fully burned.

The energy generated is just enough to push the shell out of the barrel, which is optimal.

If the charge is too much, the gunpowder has not completely detonated, and the shell will fly out of the muzzle. This is a waste of gunpowder. No matter how much the charge is, it may not increase the muzzle velocity and power much, but if the charge is too little,

, after the gunpowder deflagration is completed, the artillery shell has not yet flown out of the muzzle, which will cause friction between the artillery shell and the barrel, causing resistance, reducing the range and power of the artillery, and affecting the accuracy of the artillery.

At this point, Westerners have already come to the forefront. They have understood this principle when using artillery. At the same time, through the study of mathematics, they have produced gun charts, which make it convenient for gunners to just look at the gun charts.

Knowing how far to hit the target and how much gunpowder to load when using solid bullets or grenades can make the artillery strike more accurate.

However, as the Chinese who invented the artillery, because no one has ever paid attention to this issue, and no systematic research has been conducted, the cannon-casters are also blacksmiths, and each of them is stingy with their craftsmanship, for fear that others will learn their skills and steal them.

They lost their jobs, so they never communicated with each other and just passed it on from generation to generation. As a result, China's overall technology improvement has been very slow since the invention of artillery. Even by the end of the Ming Dynasty, China's self-made artillery batteries aimed at

There is nothing, and the accuracy of this cannon can be imagined based on the gunner's experience and estimated aiming.

However, as students, Westerners gradually formed a set of strict technical specifications during the use of artillery. In a short period of time, they produced artillery that far exceeded that of the Chinese. In turn, the Chinese also

We need to learn the art of cannon-making from Westerners, buy cannons from Westerners, and ask former students to teach them how to make cannons.

This kind of thing makes many Chinese people 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 couldn't come up with such a good artillery either.

The newly cast twelve-pound short cannon was cast using the new internal mold water-cooling technology. On the premise of ensuring the strength of the cannon barrel, the thickness of the cannon wall was reduced again, so that the weight of the cannon body was reduced.

Due to the weight reduction effect, this kind of gun can be installed on two types of gun mounts. When installed on a four-wheeled gun mount, it can be used as a naval gun on a ship, even a lightweight one that could only carry a six-pound gun in the past.

Ships can now also carry new twelve-pound cannons. In this way, once a large area of ​​​​Sea Wolf warships are equipped, the firepower of Sea Wolf's fleet can be increased by another level.

If mounted on a two-wheeled gun mount, the total weight of this kind of gun is less than 300 kilograms, which is less than 600 kilograms. It can be pulled by a horse, and it can lead the soldiers to maneuver on the battlefield, allowing the soldiers to maneuver on the battlefield.

Soldiers can gain stronger attack capabilities.

Even in mountain warfare, it is impossible to use animal power to tow artillery. When necessary, the gun mount can be disassembled, the barrel and mount can be disassembled, and carried by mules and horses to operate in the mountains. So far, this is the best method for naval artillery.

The strongest firepower the Wolf Soldier can obtain.

Even if the Sea Wolves are currently seriously lacking in animal power and are marching on short-distance terrain that is not very difficult, they can still completely replace the animals with soldiers and rely on manpower to pull the artillery and follow the team to ensure that under normal circumstances, the soldiers

It can obtain more effective fire support and fire suppression as well as the ability to attack fortresses.

The twelve-pound mountain howitzer newly cast by the artillery company has undoubtedly become a product beyond the times, greatly improving the firepower intensity of the Sea Wolf navy and soldiers.

After the successful trial production of this short-barreled twelve-pounder howitzer, it immediately began to replace the production of six-pounder guns and became the focus of the recent production of Seawolf cannons. Within a short period of time, dozens of them were built and equipped with the Navy.

and war soldiers, and the Navy naturally obtained most of them and distributed them to some ships to increase the firepower intensity of the warships.

In addition, through various channels, Sea Wolf has now basically solved the saltpeter supply problem. Not only has it stored a large amount of saltpeter, sulfur, and fresh water, but the two gunpowder workshops on Nanyue Island have also recently produced a lot of gunpowder. In addition, Sea Wolf has

The gunpowder workshop in China has always insisted on producing granular gunpowder, so that the quality of Sea Wolf's gunpowder has always been much ahead of its peers and the military. Even gunpowder from Western countries can at most reach the level of gunpowder currently produced by Sea Wolf.

Level.

Therefore, Sea Wolf is not afraid that the government will cut off their supply of materials. Now, after one or two years, the food production on Nanyue Island, although not high, can basically satisfy the people on the island and Sea Wolf tribe.

For its own needs, fresh water and chicken coops have not yet reached the level of self-sufficiency. However, after more than a year of operation, the self-sufficiency of food there can now meet about 70% of the needs. The remaining 30% of the needs can be obtained from land.

Buy.

For this reason, Hailang recently spent a considerable amount of funds after the rice matured to purchase hundreds of thousands of kilograms of grain from Guangdong and Fujian, so much so that the price of grain in Fujian and Guangdong has recently dropped.

It has been raised a bit, and now Sea Wolf has begun to run towards Guangxi, where it is purchasing grain in large quantities.

As the saying goes, if you have food in your hands, you will not panic. Yu Xiaotian knows very well how important food is to the survival of sea wolves. Once there is a natural disaster on land, there will be a large-scale famine, so he reserves it in advance.

With these grains, we can take the opportunity to attract many disaster victims and follow them to settle on Taiwan Island to make a living. This is the key to exploding the population.

In addition, the population in Tamsui and Chicken Coop is increasing, but the reclaimed land is still raw land. In addition, Taiwan has a lot of rainfall, and the current farmland drainage and irrigation facilities are not complete, so it is easy to suffer from floods. Once there is a flood,

The immigrants may not be able to harvest anything, so he can't say that he doesn't care and just watch these immigrants starve to death, so it is necessary to store food in advance to meet emergency needs.

Therefore, although Sea Wolf's income is getting higher and higher, its expenses are also getting higher and higher. No matter how much money you save, it is not as effective as saving more food and various materials. Therefore, the people in the council are not satisfied with Xiaotian's lavish spending.

He was very dissatisfied, going in with his left hand and out with his right hand, so that the Council never saved much money.

If the council had not yet had to take care of saving enough salary and reward money to pay for the Sea Wolf tribe, Yu Xiaotian would have spent all the coffers of the council.

However, the benefits are also obvious. The Sea Wolf tribe has sufficient food, various supplies, and weapons in their hands, which makes them live a peaceful life without having to worry about not having another meal.

Therefore, this time to deal with the official army's suppression operation, the Sea Wolf tribe, especially the leaders, were full of confidence and even a little geared up. They only waited for Yu Xiaotian's order to go all out and fight.

The current Nanyue Water Village is located at the southern promontory of Puxisuo on the Zhongmen Peninsula. It faces Meizhou Island across the sea, only a few miles away.

This is also the gateway to Xinghua Prefecture. To the north is Pinghai Bay, which belongs to Pinghaiwei of Xinghua Prefecture. Puxi Qianhu Institute and Pinghaiwei just guard Pinghaiwan, close to Nanyue Waterway and across the sea from Nanyue Island.

Looking at each other, the distance is only more than thirty miles.

Recently, because the governor of Fujian wants to use troops to attack Nanyue Island, he has blocked ships on a large scale along the coast of Fujian and banned commercial ships from entering the sea. As a result, the Nanyue Waterway, which is usually busy with shipping, has become much deserted.

Moreover, because the government troops began to station in Pinghaiwei and Puxi, warships also began to gather towards Pinghai Bay and Xinghua Bay, making the situation in Xinghua Prefecture much tense. Even some fishermen were prohibited from going to sea. The government's

The saying is to prevent fishermen from collaborating with thieves.
