Chapter 598 A new ship with a displacement of 500 tons (please vote and subscribe)
Thousands of people swore in the same voice, and the momentum was so great that it not only shocked Jiang Xuan, an outsider, but also deeply infected the officers and soldiers on the scene. In fact, this is the herd mentality of people. The more strict the rules and the more sealed the environment in the military camp, the easier it is to manage this kind of thoughts and emotions. Of course, if something bad happens, it will spread the fastest.
However, they have just experienced the distribution of equipment and weapons, and the morale is at its peak. Especially not long ago, these people were all wearing different private clothes. Now, everyone in sight is wearing the same military uniforms and the same mighty armor as themselves, plus the same brand-new weapons in their hands, and a kind of pride of "I am a member of the Han army" arises spontaneously.
It can be said that from today on, they are truly a whole.
After reorganizing the army, Luo Chong did not leave immediately. He still had a lot of things to do. The previous morning and evening drills were changed to armored drills. This could be considered as adding a little weight to them, and by the way, it was also to get them used to fighting in armor as soon as possible.
Copper whistles were also distributed to all the flags, one for each person. In the past, they could shout slogans every day to train the troops, and their voices would be hoarse. Now with the whistle, there were only the beeping copper whistles and the occasional slogans shouted by the soldiers on the parade ground. When these things were in the hands of the grassroots officers, they were all very rare.
In addition, most of the drum signals in the barracks were replaced by military bugles. Many signals that could be expressed by military bugles were replaced by signal signals. The new buglers were selected and trained from the personal soldiers of the two guards at all levels, and were placed at the lowest level of the unit. The instructors of the buglers were the people who Luo Chong had taught personally before.
In addition, Luo Chong also personally trained the hundreds of scouts. The most important thing was to teach them how to use the equipment, and then there was a lot of practice. In addition, there were also fighting skills such as grappling techniques and military boxing that Luo Chong learned in his previous life
. Finally, he taught them how to touch the sentry, how to scout, what to scout mainly during scouting, how to capture prisoners, and how to torture prisoners to obtain intelligence. What Luo Chong did not expect was that this batch of scouts learned very quickly. They did not learn grappling techniques and military boxing very well, but they learned the familiarity of various equipment and the things for scouting very quickly.
Later, Luo Chong summed up the reasons and realized that this group of people came from various tribes and joined the Han tribe, but before joining the Han tribe, which of these people had not hunted?
To put it bluntly, reconnaissance and wilderness survival may be something that modern soldiers need to be taught, but in this era, for these soldiers of the Han tribe, it is their innate instinct. This thing is actually not much different from hunting. It is all about finding prey first, then tracking prey, capturing prey or killing prey. The only extra thing may be the torture method of interrogating prisoners.
As for the speed of familiarization with equipment, it is because the equipment of scouts is not much different from the three-piece hunting set of primitive people. The ordnance shovel is equivalent to the stone axe, the throwing spear is still the throwing spear, but the spear head is changed to iron. The two knives are equivalent to the bone knives or stone knives in the past. Now these things are just sharper and more convenient.
Other things that need a lot of practice are bows and crossbows and blowguns. These two are long-range weapons. Few people have played with them before. Now if you want to play them well, you can only practice a lot. There is no other way.
In response to this situation, Luo Chong deliberately reduced their reconnaissance training, mainly focusing on proficient weapon use, military boxing and grappling techniques.
The rest of the arms began daily practice under the leadership of the veterans. Formation and physical training were the norm, weapons practice could take up half a day, and finally formation change practice. Every few days, physical training would be replaced by football games, using this entertaining way to relieve the pressure of training for the soldiers.
After Luo Chong spent ten days teaching them these new additions, he didn't have to teach them in person every day. He just had to urge them to practice seriously. Then he plunged into the big tent of the military camp and didn't come out. He only drew pictures inside every day.
Jiang Xuan would go to the parade ground every day to watch the soldiers train, and then return to the tent to watch Luo Chong draw pictures. Although he couldn't understand them at all, he had learned Chinese very quickly recently. There was no other way. There were people who spoke Chinese around him. If he couldn't speak, he couldn't communicate. This naturally made him learn faster.
This day, Jiang Xuan went out to observe again, and then returned to Luo Chong's big tent. Seeing Luo Chong continue to draw pictures on white paper with pencils and various rulers and compasses, he couldn't help but ask curiously.
"What is the Han leader drawing? You have been drawing for several days and it is still not finished?"
"This is a new type of ship. We must design it as soon as possible." Luo Chong said without raising his head, holding a ruler in one hand and a pencil in the other.
"Is this a ship?!" Jiang Xuan was surprised, and then asked, "Is it the same sailboat I took when I came here?"
Hearing this, Luo Chong raised his head and looked at him, and then replied calmly: "It is a sailboat, but it is bigger than the one you took."
"Bigger than that ship?!" Jiang Xuan was shocked again, "How much bigger?"
"More than twice as big." Luo Chong lowered his head and began to draw again.
Jiang Xuan was stunned when he heard this. He didn't know how to make a ship, but he thought it would definitely not be easy. When he first sat on the Han tribe's two-masted sailboat, he was already amazed by the Han tribe's manufacturing ability. But now the leader of the Han tribe in front of him actually said that he wanted to build a sailboat twice as big as that. How could he not be surprised.
Luo Chong, as the person involved, didn't care about these, and was concentrating on drawing the blueprints of several new ships.
The Han tribe needs ships, a lot of ships, and even more big ships.
Not to mention the long distance, just this army's southern expedition will require a lot of ships to transport troops, otherwise how can Luo Chong invest more than 4,000 troops at one time?
At that time, not only soldiers and supplies will have to be transported, but after the battle, so many prisoners will have to be escorted back, which will require a large number of transport ships.
Of course, these are all short-term goals, but in the long run, whether it is building a city on the grassland or transporting coal, copper, mercury, sand and other minerals downstream, more suitable transport ships are needed. The design indicators require large carrying capacity, easy operation, fast speed and other characteristics. Use the current two-masted sailing ship to transport coal? No way
Therefore, it is urgent for the Han tribe to develop a new ship type, and a large ship is necessary.
The shipbuilding history of the Han tribe has evolved from the eight-meter-long small boat at the beginning to the twenty-meter-long and six-meter-wide two-masted sailing ship now. Now it is increasingly unable to meet the transportation needs. Therefore, Luo Chong directly built a "big ship" with a load capacity of more than 400 tons and a displacement of more than 500 tons.
How big is the big ship? The length of the existing sailing ship is doubled to 40 meters long, the six-meter ship width is changed to ten meters, and the two masts are changed to three vertical masts and a bowsprit.
Although it is more than twice the size of the original, the theoretical speed of this new ship type is much faster than the original. First of all, the area of the sail is increased, which is equivalent to directly adding several more powerful engines. Because as the hull is lengthened, the new ship not only increases the number of masts, but also the height of the masts must be increased synchronously, so that the area of a sail on the new ship can be equivalent to all the sails of the old ship.
Another thing is the more streamlined ship shape. The original ketch was 20 meters long and 6 meters wide, with an aspect ratio of 3.33. Now the hull is stretched to 40 meters and 10 meters wide, with an aspect ratio of 4, which means that the hull of the new ship is more slender. According to fluid mechanics, the new ship has less resistance to sailing.
Although the new ship is larger than the original one, in terms of speed, it is equivalent to asking whether a bamboo pole floats faster in the water or a round wooden basin. The displacement of the two objects is similar, and the bamboo pole even has a larger displacement, but it is obvious that the slender bamboo pole is much faster than the wooden basin.
Even if the aspect ratio is only increased by 0.66, the increase in speed is significant.
However, for ships, the larger the length-to-width ratio, the better. The larger the length-to-width ratio, the higher the speed. This is an iron rule in shipbuilding. The speed bonus is considerable, but the longer and thinner the ship, the larger the turning radius. A sharp turn with a small radius is prone to capsizing due to the shift in the center of gravity. This is also an iron rule.
In other words, it is very difficult for a 40-meter-long ship to turn around in the river section of Liuyang County, which is at most 100 meters wide. Therefore, Luo Chong plans to put the docks for these large ships in the newly built Weishan County and complete the turning of the large ships in the lake. As long as they pass through this section of the Liuyang County basin and reach the river surface downstream, which is at least 200 meters wide and hundreds of meters wide, they don’t have to worry about turning around.
In addition, in order to facilitate manufacturing, reduce manufacturing difficulty, and increase production speed, Luo Chong directly developed two types of ships based on one type of ship.
One is a sinking bucket transport ship of the same volume, and the other is a four-story building ship.
The sunken bucket transport ship uses the same keel and hull, and has the same mast and sail configuration, but has no deck. There is only a one-story poop for the crew to live in at the stern. The front part is directly a sunken cabin, in which various ores can be directly piled. It is directly transported in the open air on sunny days and covered with tarpaulin on rainy days to prevent rain. To put it bluntly, this is a real wooden basin, without even a roof.
The building ship is different. It has the same keel, but the hull is much higher than the sunken bucket ship. There are four floors in total, two below the waterline and two above the waterline. A poop is added at the stern, so the stern can be regarded as having five floors. This is a specially set commanding height for observing the surroundings.
Such a building ship is not used to transport ore, but mainly transports large quantities of people or other water-afraid goods. It is mainly used for business, exploration and transporting troops. The two types of ships have their own uses, and neither is missing.
Luo Chong has been perfecting these designs in detail these days, because the design of such a large project must take into account the various difficulties that may be encountered in the future before construction, so it must be thought of in advance, otherwise it will be difficult to modify it after it is built.
At the same time, Feiying also sent a letter to Dashu, urging him to recruit local young and strong people as temporary workers in the shipyard as soon as possible after the autumn harvest. Anyway, they are idle in winter, so it is better to work as temporary workers to earn some extra money.
However, this is not a compulsory recruitment, but a voluntary one. I know that everyone is tired after farming for a year. If you are willing to come, I will pay you. If you want to rest at home, I will not force you.
In addition, Dashu was ordered to prepare a lot of shipbuilding materials. The planks can be sawed first and put aside for use. The keel and beams can also be prepared first. Other things such as paint and nails can also be prepared in advance.
After a few days, when the design drawings of the new ship were almost finished, the training in the military camp had also passed the first phase of basic training. All soldiers had completed weapons training and had basically mastered the methods and skills of using weapons. At this time, the grappling techniques and military boxing of more than 300 scouts were almost practiced. Then Luo Chong immediately changed the training mode and asked the scouts to set aside half a day every day to serve as instructors in other arms to train them in grappling and fighting.
This training is necessary, because Luo Chong's original intention of training this army was not to kill people, not to directly kill all opponents, but to capture live prisoners, slaves, and free laborers. The construction of the army was not the purpose. The real purpose was to let the army serve the construction, capture more laborers, occupy more resources they needed, and allow the Han tribe to develop science and technology faster.
So in the second half of the month after the reorganization, such a scene appeared in the military camp. In the morning, the soldiers were fully armed and wearing armor, holding weapons for a morning run. After breakfast and finishing their housework, they first practiced military boxing under the guidance of the scouts in the morning, and then began to practice fighting skills and grappling techniques in pairs.
The soldiers began to learn various anti-joint grappling techniques such as locking the throat, twisting the arms, kicking the knees, and breaking the thighs, as well as various methods of quickly tying people.
When such training began to get on track, Luo Chong told the eight generals to practice well and he would come back in half a month, and then ran away with Jiang Xuan.
Luo Chong led a group of people back to Hanyang City first, arranged the accompanying personnel such as the petty officials, and then sent Jiang Xuan to school. Finally, he went home to take a look, and then rushed to the shipyard in Liuyang County with the blueprints impatiently.
At first, Jiang Xuan was going to go with Luo Chong. He also wanted to see how the Han tribe built such a big ship, but he was directly rejected by Luo Chong. The reason was: "Shipbuilding is the secret of the Han tribe. You haven't agreed to join the Han tribe with your whole clan yet, so you are not qualified to watch it now."
Jiang Xuan had nothing to say about such a straightforward rejection. He knew that this was the Han leader putting pressure on him and hinting at him, "You have seen this army, and I have let you go to school. It's time for you to express your position. Do you want to join the Han tribe? Give me a straight answer!"
