Open an aircraft carrier to fight against Japan

Wan Ling is the originator-level expert in domestic ship design, but no one who met him could connect him with the old expert. He is more like a happy old man who always carries a student-like backpack on his back , There are always a few books in the bag, from professional books to online novels, all-encompassing, according to his words: "The disciplines are the same, and the shadow of the other can often be seen from one discipline."

In the evening, Lin Yuan went to pick up Wan Ling who came by helicopter, and saw Wan Ling wearing a robe and carrying a cloth bag on his shoulders, getting off the helicopter unhurriedly and walking towards Lin Yuan.

Because the personnel on the Beijing ship have more and more contacts with the local people, Lin Yuan stipulated that when carrying modern items, they must be packed with items from this era, so the Beijing ship ordered a batch of cloth bags. But this kind of bag is carried on one shoulder. Lin Yuan knew that Wan Ling must have sewed a strap on the bag himself, turning it into a backpack.

Humming, Wan Ling walked to Lin Yuan, took the earphones out of his ears, and said, "Xiao Lin, did you ask me to help design the ship?"

Lin Yuan nodded and said, "Time is tight, and I don't have time to write you a design and technical task statement, so I will briefly explain my requirements to you." The design and technical task force was proposed by the ship use department, and The starting point of ship design, which stipulates the navigation area of ​​the ship, the purpose of the ship, etc., and the design department completes the design of the hull according to this task book.

Lin Yuan went on to say: "I originally wanted to build an inland river fleet to launch an attack on Sanchakou and Sanxing, but now seeing the situation of Jilin Machinery Bureau, I want to build one or two small boats first, and use the method of sneak attack Let’s take down the Sanchakou first. So I hope that the ship can be as big as possible, with as many soldiers as possible, and then put the Gatling cannon on it to increase the firepower!"

Wan Ling looked at Lin Yuan like a monster, and said in surprise, "This is impossible!"

Lin Yuan thought: "This request is very simple, how could it be impossible!" Lin Yuan asked quickly.

Wan Ling said: "The first step in designing a ship is to calculate the weight to determine the displacement. Only with this can the following design parameters be selected. The weight of the people in the weight is an important component. I need to know how many people the ship will hold. Weight, you give me one to load as many soldiers as possible, what should I do!" Lin Yuan smiled apologetically, and said: "Then load fifty soldiers, two Gatling cannons, but there must be something that can They hide, and in our case we can only use a sneak attack."

Wan Ling nodded and said with a smile: "Your request is very simple, and it is not complicated to realize it. However, before designing, I have to do one thing first." Lin Yuan asked: "What are you going to do?"

Wan Ling said, "Find me a craftsman who is most familiar with ships."

When he arrived at the shipyard, Lin Yuan found a craftsman, the one who answered him during the day. Wan Ling looked at the young craftsman and said with a smile, "Please sit down."

No one would feel the slightest sense of oppression in front of Wan Ling, a kind and kind old man, and this craftsman was no exception. Wan Ling lowered his head, took out a pen and paper, and began to draw something on it, asking while drawing: " May I have your name?"

The craftsman replied, "My name is Zhang Dahe."

Wan Ling asked again: "Why do you learn shipbuilding?" Zhang Dahe said: "My father knew the master of shipbuilding, so he asked me to learn from him. He said that after learning shipbuilding, he would be able to do carpentry and have a craft. , I won’t die of hunger anywhere.”

Wan Ling chatted about family affairs sentence by sentence, as if he was picking a son-in-law. Lin Yuan thought to himself: "Don't talk about these things, tell him about shipbuilding."

At this moment, Wan Ling picked up the piece of paper, put it in front of Zhang Dahe, and said with a smile: "Do you know what this is?" It happened that a large shadow was cast on the paper, and Lin Yuan couldn't see what was drawn on it.

Zhang Dahe looked at it for a while, and said: "I know it, it is a bare boat." Lin Yuan thought to himself: "What is a bare boat?"

Wan Ling nodded, wrote something on the paper, then pointed to one of the places and asked, "What is this?"

Zhang Dahe replied firmly: "The keel."

Wan Ling pointed the tip of the pen to the side, and asked: "What about this one?" Zhang Dahe replied: "It's also a keel."

Wan Ling asked: "Are you sure?" Lin Yuan said loudly in his heart: "Not sure! What are you doing here?"

Zhang Dahe hesitated, and said: "That's what Master taught us, isn't it?"

Wan Ling nodded and said with a smile, "Yes, it's called this." In this way, Wan Ling asked for half an hour, and then asked, "What kind of wood do you use to build ships?"

Zhang Dahe said: "They are all pine trees, and the trees are more than 50 years old."

Wan Ling said, "Okay, go back and rest."

As soon as Zhang Dahe left, Lin Yuan asked, "What were you doing just now?"

Wan Ling put the paper in front of Lin Yuan. When Lin Yuan saw it, he understood why he called it a "bare rod ship". The skeleton of the ship, as for the buildings above the deck, engines, propellers, etc., are all outfitting contents, which are not involved in this picture.

Wan Ling said: "The reason why I asked him this is because I want to confirm the name of the hull structure in their era, just like the keel, which is the beam that runs through the bow and stern of the ship. In modern ship design, the middle one is called the inner keel. , the one on the side is called side inner keel, they called it keel in this era, and finally I asked about the material they used, and the strength and rigidity of the pine wood can determine how long the boat can be made.”

Lin Yuan asked again: "Then have you thought about how to design it?"

Wan Ling smiled helplessly: "There has never been a ship orderer like you. Many design parameters of a ship cannot be selected at one time. Generally, ship design takes quite a while, but according to what you mean, we are Build two ships in case of emergency, so that it may still be built."

Lin Yuan smiled and asked, "Do you want to draw the blueprint?"

Wan Ling shook his head and said, "General drawing, parts drawing, assembly drawing, drawing one by one, don't exhaust me. Those craftsmen are very smart, so I just talk to them directly." After finishing speaking, Wan Ling pointed to himself He said: "The captain, the width of the ship, the draft, the parameters of the ship's shape coefficient, and the structural layout plan are all in my head. After three days, I guarantee that you will form a satisfactory inland river fleet."

Lin Yuan believes in the strength of Wan Ling and the craftsmen, and these ships are also very simple to build. There are no steam engines, no propellers, no watertight cabins, and there are still many ready-made materials in the warehouse. Lin Yuan can arrange the personnel with confidence. The soldiers of the Second Brigade of the New First Division were all fishermen, and they were no strangers to rowing and steering. Lin Yuan quickly selected [-] soldiers.

Three days later, the four ships were built. On the one hand, Lin Yuan sent soldiers on board for adaptive training, and on the other hand, he ordered the new division and brigade to attack Sanchakou.

With the lessons learned from the disastrous defeat in Daheishan, the Russian army at Sanchakou no longer dared to be careless. The officers desperately ordered their subordinates to dig trenches and repair fortifications. The battle situation between the two sides was once stalemate.

At this moment, Lin Yuan's inland river fleet sailed quietly to the rear of Sanchakou!
