Great Song Pirate

Chapter 337 Katyusha
As for the range, Xu Yi has a greater pursuit. At present, he thinks that the range of this kind of rocket is not enough, so he increases the amount of gunpowder. As a result, when launching without a bow, the rocket alone flew out for nearly [-] steps, and with the launch of a strong bow, it reached about [-] steps, and it was almost impossible to see where the rocket flew. Xu Yi This is satisfied.

Anyway, he slept in a room alone when he went home. Xu Yi simply lived in the gunpowder workshop for the past few days. He didn’t even go home. A specification has been specified, and it will be produced uniformly in the future, which is convenient for mass production and use.

Then he hired a carpenter to make a big barrel that could hold 32 rockets of this kind. There were two layers of partitions inside, and 32 holes were drilled on it to fix the arrows. Then the 32 rockets were connected with long lead wires. Get up, take them to their experimental field for experimentation, don't think about it, when 32 arrows swarm out with fire, this kind of scene looks quite scary, these people who participated in the experiment were taken aback, the protagonist himself is simply It's a monster, to think of such a way, he is born to be a destructive maniac!
After Xu Yi watched all 32 rockets fly out, he stood there dancing and applauding loudly. In the end, he immediately named this thing "a swarm of bees", and the world's first mass rocket launcher was born in his hands.

Xu Yiyou was dissatisfied, and felt that it was still not enough, so he called a carpenter and gave him a blueprint. This time, he made a square box, basically the same style as a swarm of bees, but the number of rockets filled in it reached a hundred. After igniting the main fuse , this launch test is even more spectacular, a hundred rockets scrambled out of the box, almost reaching the top of the city (a hundred people in the Song Dynasty military system) the archers fired at the same time, and this kind of honeycomb-like thing , but only two or three people are needed to launch, how many times the efficiency has been improved!

Everyone stared dumbfounded at this terrifying weapon, and really didn't know what to say. This kind of thing has reached its limit. If it gets bigger, I'm afraid it won't need a car to pull it, and people will definitely not be able to carry it. Fortunately, Xu Yi stopped here He didn't ask the carpenter to make a bigger wooden box to hold the rockets. He also considered the transportation problem. It might not be easy to use any bigger. However, he thought about whether it would be possible to make a bigger rocket hive on the ship. Make a hive of [-] to [-], so that if the two sides go to war at sea, once they are ignited, the opponent's ship may be nailed into a hedgehog, and there will definitely not be many living people left on the deck.

But he temporarily dismissed the idea. The idea was good, but it would be too much of a waste of arrows. It is better to go back and build cannons. Putting a few or dozens of cannons on the ship is probably a hundred times more powerful than this rocket hive!
In the end, Xu Yi named the hive containing one hundred rockets "Hundred Tigers Running Together", and all of them were named according to the names they should have been called in later generations.

After finishing these rocket hives, Xu Yi asked the carpenter to make a small hive for ten arrows. It was considered portable, and each person could be given one or two during wartime. All of them were archers, and 100 people could be a thousand Archers use it, I am afraid that any army will cry when they meet them!This idea he borrowed from the idea of ​​​​disposable rocket launchers in later generations. Everyone can be an anti-tank player, but he just changed it into a rocket player.

Then he asked the carpenter to make a cover to cover the mouth of the honeycomb, and then take off the cover when in use. All the rockets will be packed in the box, which is convenient for storage, transportation, and use. Anyway, it is made of wood. Things, after the rocket is released, the inside is almost burnt, and it can be used as firewood on the spot when it is used up. It is also good for cooking.

Because Xu Yi didn't go home, Yingchun and the others blamed him a lot, but seeing how excited he was, they let him stay in the gunpowder workshop, bringing him the boiled medicine every day, staring at him. He had to take it, which made Xu Yi, who was afraid of taking medicine, very embarrassing.

In the past few days, Yang Ci came to ask Xu Yi several times about blood transfusions. Now he is completely fascinated by this novel way of saving lives. His mind is full of blood transfusions all day long. If he can't figure it out, he just asks Xu Yi. He took Xu Yi as his technical consultant, and he also found many people at the same time, took a needle to bleed, and then did his matching test, but Xu Yi didn't know much about how to make a match, so what can be provided to him? He has very little knowledge, so he can only rely on him to explore slowly, but he has been repeatedly told not to try randomly, otherwise it will kill someone.

However, he gave Yang Ci an idea. People in the Song Dynasty must never try it. You might as well get some Japanese slaves to experiment, which will speed up his progress. He has no guilt about using Japanese people as experimental products. The notorious Unit 731 in China is unknown to future generations. They used Chinese as logs to test their biological and chemical weapons. They are all things that kill people. Get some of their ancestors to test and save people. The way they did it was heavenly better than what they did.

Yang Ci felt chilled, he really couldn't figure out why his master hated Japanese people so much when he mentioned the Japanese people?He was always merciful to Song people, but when he treated Japanese people, he seemed to treat those Japanese people like livestock!However, he was also thinking about it in his heart, and he didn't dare to ask. He guessed that the lord must have had enmity with these Japanese people before, and now he seized the opportunity to retaliate against them. Someone came to do the experiment, and now with Xu Yi's approval, he immediately ran to Qian Laoben to ask someone to go!I don't know which unlucky Japanese will be his first victims.

By the way, Yang Ci gave him his pulse and said that he had to rest for a few more days, which made Xu Yi very worried. Now that Yang Ci is his boss, Yingchun and the others would never let him go without his consent. Liuqiu Island, he had no choice but to continue squatting in the gunpowder workshop.

Idle is idle, and besides, he is not the kind of person who can be idle, so he began to ponder again.

He found some thick moso bamboos, opened three of them, filled them with a large amount of propellant and gunpowder, connected the lead wires, and took them to the experimental field for testing. As a result, after everyone heard a loud noise, Xu Yi was ashamed After running back, only the whites of the eyes and teeth were left on the face, and the rest was covered with dust. As he walked, he shook his head and muttered: "Why did it explode just after flying? Is there something wrong? No way! I still have to try! I don’t believe it, I can’t make a rocket launcher!”

Then, without even washing his face, he got into the work shed to ponder again. He filled several bamboo tubes one after another, and continued to use them for testing. Now Yang Laoxi and the others were afraid. Explosion, if he is blown out, the people in the gunpowder workshop should all die, or they will definitely be dragged to the dogs by the Fubo army, so they hurriedly followed and pressed Xu Yi In the semi-underground fortification, let them do the discharge work.

Xu Yi had no choice but to lie down at the small window of the fortification and watch them try to release the soil rockets he loaded. After Xu Yi's experience last time, these people ran to hide in the fortification after lighting them up. The test results still made Xu Yi feel Frustrated, there was nothing wrong with the small rocket, but when the big rocket ignited, it either exploded or couldn't fly very far and deflagrated, and fell down, or couldn't fly very far, which made Xu Yi scratch his head in anger.

After Xu Yi calmed down and thought about it for a while, he felt that it was not the problem of gunpowder, but the problem of loading. There was too much powder in the big rocket, and it might not erupt but detonate. How to solve this can make the gunpowder explode? What about the even burn issue?Xu Yi didn't use his brain much. He studied mechanics and didn't have much experience in this area.

He tried again and again and failed again and again, but he still refused to give up. He just couldn't believe that he couldn't make a large rocket that could fly out. up!Is he not as wise as the ancients?So he got into the shed again.

In the end, he really had no choice. He had tried the method of gunpowder filling, but it didn’t work. Filling it loosely still didn’t work. Another long drill bit was found, and a finger-thick hole was drilled in the middle of the filled gunpowder. After installing the lead wire, he carried it to the experimental field.

The gatekeepers here have been scared by Xu Yi for the past two days. The bamboo tubes either exploded or flew randomly. God knows where the next bamboo tube will land. If they are killed by Xu Yi, they will even cry for grievances. There was no place to complain. After seeing Xu Yi, Yang Laoxi and others coming with bamboo tubes, they quickly saluted Xu Yi and let them in. Then they immediately found a place to hide to avoid being caught by Xu Yi. Yi's oolong rocket was blown to death.

After one of his subordinates lit the fuse, they rushed into the bunker. Xu Yi and the others nervously lay on the lookout window watching the smoke slowly rising from the big bamboo tube. Finally, the big bamboo tube roared, and a dazzling puff of smoke emerged from its tail. Flame, and then soared into the air and took off.

"Aha! It's done! Haha! It's done! It's a success! Haha..." Xu Yi danced and jumped up in the bunker. This time he finally saw the earth rocket flying, and he jumped up happily .

But before he was happy, he heard Yang Laoxi and the others exclaim: "My lord, get down!" After saying that, several people threw themselves on Xu Yi, and pressed him firmly to the ground under the bunker. The pile of people who were crushed almost didn't hold back Xu Yi's anger, and they didn't know what happened.

When Xu Yi was about to reprimand them and let them get up, he heard a loud bang above the bunker, which caused dust to fly in the bunker and filled the air. Only then did Xu Yi realize that the earth rocket that flew out just now turned around and flew away. When they came back, they finally flew to their bunker, and the remaining gunpowder detonated. Fortunately, they were all inside the bunker. If they were outside, they might be blown out. Dead wronged.

The people inside the bunker were coughing due to the dust and the gunpowder smoke pouring in from outside. The guards of the experimental site immediately yelled at the Lord, rushed towards the bunker, and rushed into the bunker. He kicked these few people out, and looked at a few more people, and now they couldn't tell who was who, and they all looked disheartened.

Xu Yi sat on the ground and patted his legs and shouted: "Good! It's really good! Finally, hard work pays off!"

His movement scared the others enough, they thought he was going crazy, so they all called his name, for fear that he would be in big trouble if he really went crazy.

Xu Yi laughed and waved his hands and said: "It's okay, I'm okay! Haha! It's just that I was almost crushed to death by you just now! I'm so happy! We have another powerful thing! Haha!"

Everyone questioned him for a long time, checked his body, and after confirming that he was fine, they breathed a sigh of relief. This lord is really not something ordinary people can guess, and it is really terrible to make a sabotage thing!He was fine, but he scared the gang to death.

Xu Yi finally solved the problem of uniform burning of the gunpowder, and the rocket can be lifted into the air. The reason for the guy flying around just now is that there is no stability at all. Think about a round thing with a flat head in the front and no tail in the back, so it doesn’t fly around randomly. That's weird, but Xu Yi doesn't care about its current accuracy, but about whether it can fly far. Once this problem is solved, the rest will be easy to handle.

He ran back to the workshop non-stop, summoning people to continue to trial-produce this kind of thing that everyone regards as super dangerous. The bamboo tube is too crude to be used as a rocket shell, and there is a serious ablation problem at the tail. Often the gunpowder has not been burned. It is already gone, so the thrust is reduced, otherwise it can fly farther.

So Xu Yi asked the blacksmiths to smash out a thin iron sheet, wrap it in a layer, and have a reserved nozzle at the tail, so that the nozzle will not be completely burned before the gunpowder burns out, and the rocket can fly farther. There are rockets that can’t just fly out, and a burnt empty tube falls on the enemy’s head and kills at most one and a half, or scares the opponent, so it needs to be equipped with a so-called warhead, so the blacksmiths have another job. After they were done, they were asked to cast a conical warhead and put it in front of the rocket. After having previous experience in making iron-clad thunderbolts, casting such a conical warhead was no problem for the blacksmiths under Qin Huzi. Next, according to Xu Yi's drawings and the size he requested, he quickly made a sand mold and cast it out.

As for the fuze, Xu Yi used a lot of brains. Without thunder mercury, there is no way to make a trigger fuze door. At present, he can only make a fuss about the fuse, but how can the rocket explode after landing?This problem really gave Xu Yi a headache for a while. Later, he had an idea and asked the blacksmith to leave a filling hole in the back when casting the warhead, and then blocked the hole with a long wooden plug filled with delayed gunpowder. The end is connected to the rocket, and when the trigger is burned out, the fuze inside the cork is also ignited, but the warhead can only be detonated when the rocket lands, thus solving the problem of detonation.

Xu Yi didn't want to see a rocket that had been loaded with warheads flying around, and then turned around and landed on his head. He didn't want to see a rocket without a stabilized tail. There was a possibility of defecting to the enemy, so Xu Yi once again ordered the blacksmith to install the tail fins smashed out of iron sheets on the rocket, and a modern rocket prototype took shape.

This time Xu Yi didn't think about doing things like fire dragons coming out of water or flying crows, flying sky and thunder, because the ancients didn't understand aerodynamics at all, and he had modern knowledge. It would be unreasonable to get that thing, so he made a big stride and made rockets. Now what he wants is a weapon with enough power, and what he wants is the ability to protect himself, regardless of whether it violates the process of historical development. !He would not be so stupid as to put good things aside and put the lives of his men in them during the war.

It is not troublesome to make such a thing. He has all kinds of people under his command now, gunpowder can be prepared at any time, carpenters and blacksmiths are not short of everything, and they can produce more than a dozen rockets of various shapes in two days. Yi took people to the test site again for the launch test. This time everyone in the test site hid in the bunker. God knows if the thing will turn around and fly back this time. They are all confused by Xu Yi's madness these days Scared.

The first one was a rocket without gunpowder in the explosion department. Xu Yi built a directional shelf for it, and then ordered people to ignite it. Everyone lay down in the bunker and watched carefully. After the rocket was ignited, it immediately set off with a coaxing whistle. There was a cloud of dust and thick smoke, and it flew out with black smoke. Xu Yi lay on the window and stared carefully. This rocket lived up to expectations. It didn't fly back midway, but wobbled and flew out in an irregular posture. All the way, and then plunged headlong into the hillside in the distance.

Everyone was relieved now, the one with the tail fins was different, at least the possibility of turning around and flying back was much smaller, so they cheered immediately.

With their shoddy rockets at present, thank God if they don’t fly back, Xu Yi didn’t want to pursue its precision, just solve the problem of flying out first, give them an idea, and let Yang Laoxi and the others The craftsman has nothing to think about. Anyway, he is not in a hurry to use it now, and he has time to improve it.

The first rocket flew out for about three miles, far beyond the range of all current cold weapons. Even if the three-bow bed crossbow was brought in, it would not work, and the three-bow bed crossbow was too heavy. Ten people came to serve, but Xu Yi was not interested in it, even if the accuracy of the three-bow bed crossbow was much higher than that of his soil rocket, what he wanted was this kind of weapon that could be carried easily, relying on its explosive power rather than Accuracy, if you want accuracy, you still have to rely on the cannon, which is more powerful than the three-bow bed crossbow.

The launch test of the first one was roughly considered a success. At least it flew out in the direction they expected, and landed in the roughly desired place. This is a good sign, so they released two more such rockets without warheads. , basically landed on the opposite mountain, so everyone's confidence soared, and Xu Yi decided to test that kind of rocket with a warhead.

The soil rocket ignited and flew out with a roar, but this time they didn't see the rocket land on the opposite mountain as they wished. Instead, after flying into the air, the rocket exploded into a circle of fireballs with a loud bang, Xu Yi and the others They all shrank their necks in fright.

This kind of result was also within Xu Yi's expectation. It must be that the length of the lead wire was not well grasped, so it exploded before landing. So a group of people worked hard for a while, and installed a longer lead wire for the warhead of the next rocket. try!This time the rocket flew out according to the expected trajectory, and landed accurately on the opposite hillside, but it didn't explode after waiting for a long time. Climbing out of the bunker, there was a loud bang on the opposite hill, the rocket exploded, and the craftsman who had just hugged a rocket was shocked, thinking it was the explosion in his hand, almost lost his soul I was so scared, and after understanding it, everyone let out a burst of laughter.

Xu Yi became addicted, and within a day, he shot out more than a dozen of these rockets. Among them, two or three failed to fire, two exploded in mid-air, and one warhead fell off when it was in the sky. The scary thing is that one of the tails lost its tail after it was launched. As a result, the rocket started to spin all over the sky, turned around and defected back again, and scared Xu Yi and the others to death. It landed on a nearby mound of earth, and it exploded immediately, shocking these people into a cold sweat, saying nothing to let Xu Yi stay in the gunpowder workshop anymore, God knows what horrors he will make Maybe he didn't set off to Liuqiu Island, and this place was blown into the sky by his dangerous stuff.

After hearing the news, Yingchun and Yiqing brought Xu Yi back home with Qian Laoben and recuperated at home honestly. Xu Yi begged them unwillingly to let him stay for two more days. He still had an invention that he had not paid for. What about Zhu Shi, but these tigress didn't agree to anything, and even dragged him out of the gunpowder workshop. Xu Yi turned his head and confessed to Yang Laoxi: "I'll go home and have a rest, and you can continue to do it." This thing, I want you to finalize the shape, this thing should not weigh more than [-] catties, and it can be carried by a person on the road, and the blacksmith needs to make a detachable shelf, and it must be carried by a person. I have already thought of a name, from now on it will be called Katyusha!"

Everyone finally wiped their sweat and sent Xu Yi home. Since then, Dulong Island's unique weapon, the Yingchun Rocket, has been announced.

(The reason why it is called Katyusha is because Katyusha in the Soviet Union was so famous in World War II that it unanimously influenced the development of rocket launchers in the world, but it is somewhat misnamed here, just to show respect for Katyusha rocket launchers. Brothers who have read this chapter, don’t come out and yell! Also, the rocket is actually not difficult to make, it’s just a large fire. Everyone has played with such gadgets as a child. It’s very simple. It’s actually a The simplest rocket, as long as you don't pursue precision, with the current capabilities of Dulong Island, it is not troublesome to make a large fire, and it is a hundred times easier than making a barrel artillery! And it can fly very far, with the ability of pig feet!)
Here is the [-]-word chapter, and today's three updates, [-], are guaranteed to be completed!
