Datang romantic little landlord

Page 688

The reason why he knew so clearly was because he was also a military fan who visited various military forums for a long time.Weapons like crossbows are still used even by the special forces of later generations.

The sound of crossbow installation and firing is very small, suitable for silent sniping, and the accuracy is quite high. It is the standard equipment of special forces.

As for why you don't use a muffler, that's because real firearms, even if you use a muffler, the sound is not small, and it's not as quiet and motionless as in the movie.

Although Li Wangyou has never played with a real crossbow, he has never eaten pork and seen pigs running. He has also seen many photos and drawings of various crossbows on military forums in later generations, and he is very impressed with the pulley block.

The pulley blocks on crossbows of later generations use eccentric wheels.

When the eccentric wheel rotates, the radius of movement is different, from short radius to long radius, the pulling force generated is changed from a labor-intensive lever to a labor-saving lever.

It can save one-eighth of the winding effort, this statistic is also what he saw in the forum.

The range of the crossbow is actually greater than that of the bow and arrow. Taking Datang as an example, the maximum range of a bow is usually two to four stones, while that of a crossbow is about two to four stones.

Even if it is a strong crossbow with two stones, it needs more than 200 catties of pulling force to stretch it. Of course, Li Wangyou can't do it no matter what.

But if you use a pulley block, you only need twenty or thirty catties of strength to stretch the string.No matter how thin Li Wangyou is, he still has a pulling force of fifty or sixty catties, so he can naturally pull the bowstring.

And even if this data is wrong, it is impossible to save so much effort, he still has other ways to pull the bowstring, that is the principle of leverage.

Combining the pulley block with the principle of leverage, he did not believe that he could not pull the bowstring of the crossbow.

It was precisely because he thought of a way that Li Wangyou made a bet with the dudes.

But this kind of crossbow, Datang does not have.

Although Li Wangyou knew the general principle, it would take some time to do it, so he made an agreement with the dudes to go hunting in the mountains in ten days.

Seeing Li Wangyou laughing so obscenely, the dandies couldn't help but start to murmur in their hearts, thinking that they were being played by this kid again when they waited for others?But everyone thought about it, but they didn't think there was anything wrong.

They are "illiterate", of course they don't understand the principles of physics, let alone the principles of pulley blocks and levers, so it is reasonable for them to be played by Li Wangyou.

The two sides agreed on a bet, and Li Wangyou didn't bother to stay in the hospital to accompany Cheng Chumo, and led Niu Wu to leave in a hurry.

He was going to Cuiwei Palace to look for Yan Liben in the ordnance workshop. Whether this new type of crossbow can be made or not depends entirely on Yan Liben's ability.

Li Wangyou is actually looking forward to hunting.

Later generations of Europeans and Americans often saw photos and videos of hunting with shotguns and crossbows, which often made Li Wangyou drool.But in the later generations of China, where are there wild animals for people to hunt?Those who can survive are protected animals.

After traveling to the Tang Dynasty, Li Wangyou also wanted to try hunting in the mountains with the dandies, which should be very enjoyable.

But with his foolish arrow technique, even a rabbit can't hit it, not to mention that jackals, tigers, leopards and bears can be seen everywhere in the mountains and forests of Datang.If you don't have good archery skills and go hunting rashly, it is simply to "send warmth" to wild animals.

However, the reason why human beings are advanced creatures and can occupy the top of the food chain is naturally not a strong body, but brains and tools.

When the new crossbow is built, Li Wangyou, who is powerless, can follow the dandies into the mountains to hunt, and enjoy the thrill of hunting prey with his own hands.

752 Spring Steel

Li Wangyou was extremely excited when he thought that he could kill all directions with the improved bow and crossbow. He led Niu Wu and others out of Chang'an City and rushed straight to the valley of Cuiwei Palace.

Yan Liben heard the report from his subordinates, his master came, and hurriedly came out to greet him: "Disciple Liben has met the master, why is the master free to come to the ordnance workshop today?"

No wonder Yan Liben asked this question, Li Wangyou is a complete lazy person, he has a lot of whimsical ideas, but he basically doesn't want to do those trivial things.

The valley where Cuiwei Palace's royal residence is located has almost become Datang's first industrial base. Black smoke billows every day, and the sound of hydraulic forging hammers can be heard endlessly.

But Li Wangyou rarely came here, Yan Liben always went to him for advice on anything.That's why Yan Liben asked curiously when he saw Li Wangyou suddenly appearing.

Li Wangyou said: "There is no need to be courteous, as a teacher, I came to ask you for help today."

"What do you need, Master? Just tell Liben to do it." Yan Liben replied respectfully.

"I need you to let the craftsman who will be the prisoner help me build a crossbow."

Yan Liben was a little strange when he heard the words. His teacher needed a crossbow, so he just asked Cheng Yaojin and those military leaders for it. Why did he need to make it again?

Although the people of the Tang Dynasty banned crossbows, such nobles as Li Wangyou are naturally not among them. Who can say no to him if he wants to play with crossbows?

"Master, do you need a broken crossbow or a horned crossbow? The disciple can just send it to the master, there is no need to make it again."

Li Wangyou shook his head: "No, no, the crossbow I want for the teacher is not the two military standard crossbows, but a new crossbow designed for the teacher."

When Yan Liben heard the words, he immediately became interested.

As a general and junior supervisor, besides painting, he is most interested in making these mechanisms. Hearing that his master has a new crossbow to build, he quickly asked: "Master, do you have any blueprints?"

"You ask someone to bring you a pen and paper, and I'll show you a drawing." Li Wangyou asked someone to bring a pen and paper, and began to draw Yan Liben the shape of the crossbow he imagined.

The modern bows and crossbows of later generations are much more powerful than the ancient crossbows.

Even for civilian-grade crossbows, the initial velocity of the arrows fired is [-] meters per second.A modern composite crossbow with a more scientific design.Not only is the shape similar to firearms, but most of them are also equipped with scopes. The aiming equipment is perfect, the comfort experience is better, and the shooting accuracy is naturally quite high.

Li Wangyou read information on the Internet that many well-made modern composite crossbows can accurately hit a coin at a distance of 200 meters, and their accuracy is almost comparable to that of a sniper rifle.

Today's bows and crossbows of the Tang Dynasty are mostly made of natural materials such as bamboo and wood, and the energy efficiency of arrows is low in conversion, which is completely incomparable with the modern composite crossbows of later generations.

Of course, it is impossible for Li Wangyou to create a composite crossbow in the Tang Dynasty.

Those composite crossbows can not only be made by knowing the appearance, but also many modern subjects such as material science, ergonomics, mechanics and so on are involved, which are far beyond his comprehension by a college student majoring in e-commerce.

But Li Wangyou can find a way to improve the accuracy of the crossbow and reduce the tension of the crossbow string, it can be done.

At least he planned to use steel sheets instead of wood to make crossbows.

Now with the use of hydraulic forging hammers, the ordnance workshop located in the valley of Cuiwei Palace can forge a lot of refined steel every day.

Li Wangyou felt that it should be possible to use these steels that have been tempered and tempered to make crossbows.

As for the shape of the crossbow, he directly copied the appearance of the crossbow of later generations. If the crossbow arms and strings were removed, its appearance would not be much different from that of a sniper rifle.

Li Wangyou even planned to fix the binoculars made by the general supervisor craftsman to the body of the crossbow as a scope.If he doesn't believe it, he won't be able to hit his prey when this new crossbow is built.

Yan Liben became more and more amazed at the blueprint drawn by Li Wangyou, and couldn't help asking: "Master, the arm of your crossbow is so thinly drawn, it seems that no wood can make it like this without breaking."

Li Wangyou shook his head: "Wrong, Liben, the crossbow arm I drew is made of steel instead of wood."

"Steel sheet? This...how is this possible? How can this steel bend like this?" Li Wangyou's words stunned Yan Liben. In his perception, it is impossible for steel to bend like this.

Li Wangyou didn't think there was anything wrong with it, so he replied as a matter of course: "Naturally, spring steel is used to make the arms of the crossbow..."

Halfway through his words, he suddenly felt wrong, paralyzed, it seems that Datang does not have such steel as spring steel, right?

Since ancient times in China, it seems that no metal springs have been unearthed.The soft sword that can be wrapped around the waist and used as a belt is only fabricated in martial arts novels. In reality, there is no such soft metal sword at all.

Of course Yan Liben didn't know what spring steel was, but the crux of the matter was that he didn't know either...
