Chapter 84 Reverse Crossbow
"Don't be excited, don't be excited, so do you know something like a crossbow? Come on, do me a favor!" Hong Tao didn't know why Carl hated the crossbow so much, probably because he had suffered a loss. It has nothing to do with him. All he wanted was his understanding of the crossbow, and then asked him to help him see if the crossbow he made was qualified or not.
Why don’t you look for others? This is what I ask. Crossbows were contraband in later generations. Hong Tao felt that it should be similar in ancient times, and it was not safe to look for others! It was not that they were afraid that they would betray them, but that they were afraid that they would scare them. The word rebellion is still very terrifying at present.
Crossbow is a crossbow. These two things are the same word in Latin and English. Crossbows are called by Chinese people and were first created by China. As for when they were spread to the West, Carl said that it was not long ago. The first crusade of the Crusaders suffered from the loss of Arab crossbows. A crusader who had been trained for many years could be killed by an Arab peasant who had just gone to the battlefield with a crossbow. Therefore, Europeans, including the church, hated this kind of thing to the core. Although they learned how to make crossbows with Arabs, the restrictions were very strict and they were not allowed to be spread at will. Anyone who made and used crossbows privately was discovered by the church, would be executed.
Can Hong Tao make hand crossbows? Not to mention hand crossbows, he has even made mortars on the Superman of the Rat. The female mechanical and electrical workers on the ship are all his personal accompanies. They teach him what they want. The planing, milling and drilling machines in the workshop are all digital. As long as Hong Tao wants, he can install the steel furnace and can't make anything. When he gets tired of guns and cannons, he sometimes plays with antique weapons, such as compound bows and compound crossbows, and uses them to shoot fish in the sea. After getting tired of playing, he starts to think about dismantling them. After dismantling them, he thinks about making them by himself. After making them, he loses interest and goes to find other fun things.
What Hong Tao made this time was a very tall modern composite crossbow, but the material was not carbon fiber and alloy, but whale bones, whale bones, whale tendons, bamboo slices, hardwood and ordinary Song Dynasty steel. The thick whale bale was cut into strips of one centimeter thin and five centimeter wide, one was longer than the other, and the longest one was only about 4 centimeters. They were perforated and tightly wrapped with thin wire ropes. This was the crossbow arm, commonly known as a shoulder pole.
Choose the thickest ribs of whale bones and process them into a rifle body with a stock of more than one meter long, and install them with a trigger carved from hardwood, which is the crossbow body. It’s just that there is no spring, and when the string is not hung, the trigger will bang back and forth.
A straight shallow groove is carved on the plane of the crossbow body, with both sides high and low in the middle. This is the track of the crossbow arrow. After being placed, both ends will be placed in the shallow groove and slightly suspended in the middle. This is to reduce friction and make the crossbow arrows initially faster. However, this also has disadvantages, which is that the production of crossbow arrows is very high. If it is a little bit straight, it will have deviations after being shot, and the accurate head is not high.
There are three magnets embedded under the shallow groove, so that even if the crossbow is erected, the steel crossbow arrows on it will not fall. Pushing a straight whale bone piece with a shallow groove on the crossbow body is equivalent to covering the crossbow arrow between the two whale bones, leaving only a smooth gap, which is where the bow string is moved. There is also a leather sconcealed in front of the crossbow body. When the string is turned on, step on the leather sconcealed with your feet and pull the bow string with your arms, and you can hang it on the trigger's sconcealed tenon. This clamping tenon is also a mountain viewing, taking into account both the distance measurement and aiming.
If such a crossbow is just like this, it cannot be considered a composite crossbow, and its shooting distance and power are also very average. It would be good to shoot people to death more than ten meters away, but it can only be considered a toy but not a weapon. Of course, Hong Tao would not be so unprofessional. At least he has made modern composite crossbows by himself, and even designed it by himself. The appearance of his crossbow is very different from other crossbows, and even people who have never used crossbows can tell at a glance.
This difference is mainly reflected in two aspects, first of all, the crossbow arm. The crossbow arm of his compound crossbow is not bent backwards, but is like a small wing, folded from the middle and back part of the crossbow body, slightly spreading, and putting it with the crossbow body, looking a bit like a three-stranded fork.
This is called a reverse crossbow, which is a high-tech technology in later generations. It can reduce the width of the crossbow body, but does not reduce the firing force of the crossbow, and can also reduce the elasticity requirements for the crossbow arm material. It only needs to be elastic and tough, but does not use very long materials to be used as a bow arm. The whale baleen just meets these characteristics. It has very good elasticity and is not tough enough. If it is made more than one meter long like an ordinary crossbow, it will deform after being used for too many times, but it will be fine after being shortened.
Ordinary crossbows rely on the force of the crossbow arms being bent backward and then bounced forward to drive the bowstring, while the reverse crossbows rely on the force of the bowstrings on both sides being pulled inward and then bounced outward to drive the bowstrings. However, the movement distance of the bowstrings of the reverse crossbows is very short and cannot produce such a great elasticity. What should I do? Hong Tao has a way to make up for this shortcoming with a large eccentric wheel set.
The eccentric wheel set is the main component of modern composite crossbows. It is generally composed of three to five eccentric wheels in a certain structure and is installed at both ends of the crossbow arms. When you pull the bow string, the eccentric wheel set rotates accordingly, which will not save you a trace of effort. But the more you pull, the shorter the center of its circle, the more effort it saves. You can turn the string with one hand at the end. This is exactly the opposite of ordinary crossbows. Ordinary crossbows are the most labor-saving when they are just pulled. As the bow arm becomes more bent, the more effort it is getting pulled.
After pulling the trigger, the pair of eccentric wheels is at the highest point of the torque. With the elasticity of the bow arms on both sides, the strength of the bow string will be greatly increased. After the eccentric wheels turn, the bow string will stop moving.
Speaking of which, the principle of this eccentric wheel set is very complicated. The size and axis position of each wheel in a combination are strictly specified, which will reduce the effect or even fail to work. They are all designed by computer assistance. From three wheels to five wheels, there are N combination methods. Hong Tao only remembers two of them. One set is entry-level, and three wheels form a group. The explosive power is not strong, but it can make the bowstrings very labor-saving. The other set is a high-level combination of five wheels. This combination is developed by crossbow enthusiasts themselves. There are no finished products sold outside, and they all have to rely on their own processing. Its characteristics are exactly the opposite of the combination of three wheels. It is not very helpful for pulling the bowstrings, but it has high explosive power, which is more than half of the composite crossbow of the same level.
"What is this?" Carl followed Hong Tao to the east of the island. There was a forest of trees, and no one came over. When he saw Hong Tao picking a strange thing with three strings and two pairs of big wheels from a small tree, he didn't recognize it. This was the crossbow that made him hate extremely.
"I designed the crossbow, please help me identify the difference in range and accuracy of the crossbow of your empire. I can continue to modify it." Hong Tao did not make things difficult for Carl, but stepped on the leather case with his feet, hung the bowstring up with both hands, then lifted the protective cover on it, put a round iron chopstick at the end, and then grabbed the protective cover with one click, and lifted it up with one hand.
"Is this a crossbow? From Dasong?" Carl still didn't believe it was a crossbow. He didn't understand. The bow arm of this crossbow not only did not open, but also contracted back. It was almost stuck to the crossbow. How should I fire the crossbow arrow?
"No, this is what I invented by myself based on the Australian Crossbow. Come on, let's try the power of a 10-meter distance... It's about 11 yards. This is how the code on your side is calculated?" Hong Tao pointed to a tree in the distance. He had a piece of rag nailed to the trunk. Someone's body size. Unit! It's still a unit. Now Hong Tao is almost confused by the unit of measurement at this time. If you want to talk about different units with different people, no wonder Qin Shihuang wanted to unify the weight and measure, it was too necessary!
"Bang...buzz...bang!" Three different sounds sounded almost at the same time. Hong Tao's crossbow arm suddenly opened outward, just like a flower. The two secondary strings and one main string instantly shrank together under the guidance of the eccentric wheel set. These changes made Carl dazzled and didn't even think about seeing whether the crossbow arrow hit the target.
"Hey, what are you looking at? Look at where!" Hong Tao saw a brain breakdown on Carl's forehead, and then he woke him up.
"Oh...it...it can't be pulled out..." Carl ran towards the tree in the distance, and turned around to think about the principle of the crossbow in Hong Tao's hand. The wheels on it really made him puzzled. When he ran to the trunk, he found something even more puzzling to him. Half of the steel chopsticks had been buried in the trunk. Even if the trunk was a little softer, the power of this crossbow was too great. If it was shot on a person, even if he was wearing full-body armor, he would probably be done! When he thought that someone might be aiming at him in the future, Carl's back became numb and his words were not clear.
"Then I don't want it. I have it. This time it's 20 meters, about... more than 21 yards! I said to Carl, you don't know how to learn Chinese, is it that difficult to learn weights and measures? I'll give you two months. If it's spring, you still can't figure out the relationship between rice, ruler, and ruler, and feet. I'll shoot you three times with this thing. Even if you pass the exam, you're not humble!" Hong Tao took out the same steel chopstick from under a small tree, pulled the string, flipped the cover, raised the arrow, and pulled the cover in one go. He also took the time to scare Carl, raised his crossbow to aim at a tree farther away, and quickly pulled the trigger.
"God... I still can't pull it. Is this 21 yards?" After hearing the three voices, Carl immediately ran over, his face even more ugly. The crossbow arrow was no different from what it was just now. It was still half shot into the tree trunk, and human power could not pull it out at all.
