"Brother, look, this is a continuous shooting firearm that I came up with. The principle is that multiple tubes are bundled together and the rotating shaft is rotated to form continuous shooting firepower, thereby achieving the purpose of continuous shooting." Xu Youtang pointed to the weapon.
Machine Gun said with a temperament that was quite incompatible with this era.
The surprise on Zhang Yanling's face did not fade away, and she couldn't put it down while stroking the cold gun body in her hand.
"How could you think of building something like this? It's really amazing. I don't remember asking you to do this," Zhang Yanling said.
"But my elder brother said before that there is a firearm that can fire continuously. It can fire a series of shots without having to change the ammunition one after another. It can fire dozens or even hundreds of rounds of ammunition in a short period of time. You told dad
"Yes." Xu Youtang said.
Zhang Yanling said with a smile: "I did tell your father, but it was just a casual comment. With the current characteristics of gunpowder, it is impossible to create a bullet fired by a primer, so it is impossible to create such a thing. I have no idea.
I didn’t think too much about it.”
Xu Youtang smiled sweetly and said: "Of course you can't remain indifferent to the things that elder brother wants to create. Although you just said it casually, I have always remembered it. I asked dad, and dad said that the kind of primer-fired bullets that elder brother mentioned
, requires a very high sensitivity of gunpowder. The gunpowder we use now simply cannot achieve this effect. It is indeed difficult to improve gunpowder, and the gunpowder workshops of the Ming Dynasty have not been able to match this kind of gunpowder for so many years.
Gunpowder that can explode when struck by a firing pin. Therefore, my father also said that the idea is good, but it may be difficult to realize. However, I am not convinced. I think that the powerful and sensitive gunpowder fired by the primer may not be suitable.
We can compare it, but can we find another way? Isn’t what I want is a firearm that can fire multiple bullets continuously and quickly? As long as this goal is achieved, doesn’t it mean that the requirement has been met?”
Zhang Yanling turned to look at Xu Youtang and said with a smile: "So you came up with the method of multi-management clustering? You are really smart."
Xu Youtang smiled sweetly and said: "It's not that simple. I thought it was simple, but when I did it, I was dumbfounded. There are many problems. This kind of cluster firearm cannot be a simple blunderbuss bundled together. Otherwise, wouldn't it be stupid?
A bulky and useless thing. All shooting barrels must share a firing device.
, share the mechanism of a set of ammunition. The firing device of the bird gun can learn from its principle, but in terms of structure, loading of ammunition, and the transmission design of the entire machine, it needs to be re-layout and integration. This alone makes
I haven't made any progress for months. I can't sleep at night and my hair has fallen out a lot."
Zhang Yanling fully understands the difficulty of this matter. If we can learn from it and just improve a firearm, then there is not much difficulty. It is nothing more than optimizing the weak links and unreasonable structure. At least there is
referenced.
But it is simply too difficult to create a physical object based on only one concept without any reference. Zhang Yanling asked herself that she could not design something that she had not seen. She could only design something based on known impressions.
Based on the principles and principles, the bird cannon can be made with the help of the Xu family's father and daughter. Based on the actual Folang cannon, the improved Dragon Roar and Tiger Howl cannon can be imitated. On the basis of the Ming Dynasty treasure ship, only the Ming Dynasty armor can be made by brainstorming.
Warship.
Like Xu Youtang, it's like groping in the dark. The mechanical structure and system need to be re-planned and designed, which is actually a brand-new invention. From this we can see the suffering involved.
Zhang Yanling didn't know this before. Now when she saw Xu Youtang smiling and saying this, she felt moved in her heart. She reached out and hugged Xu Youtang in her arms, kissed her and said, "You must have suffered."
Xu Youtang smiled and said: "I'm not afraid of suffering, I'm afraid of not being able to help you. But I saw many pictures of strange things that you drew in your study, which is the one you put on the bookshelf. I was deeply inspired.
."
Zhang Yanling laughed. He did have a picture album of his own in the study, but it was not something for entertainment like elegant ink and wash paintings. Instead, Zhang Yanling took the time to recall things in order to prevent himself from forgetting some things in his own memory in future generations.
and recorded some mechanical principles and drawn graphics.
Of course, it is limited to things that Zhang Yanling can remember and understand the principles. There are a lot of messy records above, most of which are things that cannot be manufactured these days.
Zhang Yanling placed this booklet in his study. Only Xu Youtang would read it from time to time, because she was the only one who did not think that the devices Zhang Yanling drew were whimsical. What machines could boil water and spin wheels, and what machines could travel on the road without manpower and horsepower?
Running cars, etc. Xu Youtang never regarded these things as random drawings, although she did not understand most of them. However, some devices have been realized.
For example, flintlock muskets, flying wings gliding in the air, etc., she had personally experienced and seen them with her own eyes. Xu Youtang could also understand the general outline of Zhang Yanling's annotations and explanations of principles beside all the graphics.
Father Xu Gao made an intercourse
When it flowed, Xu Gao also felt that it could be achieved. What hot air drives the crankshaft and converts it into mechanical force through gears? Ordinary people will naturally not notice these principles, but a master craftsman like Xu Gao who is good at manufacturing understands the truth.
of.
Xu Youtang didn't know how Zhang Yanling could know so many strange things in his mind, but she never doubted its authenticity. She just felt that she was not as intelligent as Zhang Yanling.
She often looked through the picture album and notes to find inspiration, and she read it often and gained something new every time.
"After more than four months of thinking, I finally figured out a few difficulties. The integration of the mechanical structure is actually not difficult. By rotating the barrel, the barrel can be cycled to fit the firing device at the rear, and a set of firing devices can be achieved.
The device achieves the goal of cyclic shooting. The real difficulty lies in how to achieve cyclic ignition and firing and rapid loading of ammunition. If these two problems are not solved, this thing will not be of much use."
Xu Youtang left Zhang Yanling's arms, pointed at the rear mechanism of the machine gun and continued: "Nowadays, our firearms can only rely on ignition to ignite gunpowder to complete shooting. Before the invention of the gunpowder that can be detonated by a firing pin as the elder brother said, I can only have
This way.big
Brother, you see, this is a double-piece flint fire mechanism. Every time the barrel rotates, it will drive the faucet to strike a fire on the flint. Each strike can ignite the fuse and fire. Although the speed cannot be too fast, it can be fired in one breath.
One time or faster is achievable."
As Xu Youtang spoke, he began to shake the handle vigorously. A scratching sound was heard, and the eight barrels in front began to rotate. At the same time, a squeaking sound was made at the interface between the barrel and the firing device, and an explosion erupted.
The dazzling sparks come. That is the fire that emerges from the internal faucet driven by the mechanical structure striking the flint every time it rotates.
"Very good. Very delicate. The two pieces of flint can ensure that the fire will definitely start, which is very stable. It also prevents the flint from being worn out and even causing the fire to fail at critical times. It prolongs the shooting time and does not need to be replaced frequently." Zhang Yanling stretched out his hand to shake the rocker and watched.
With sparks shining brightly, he nodded in praise.
"Exactly. Big brother understood my thoughts right away." Xu Youtang said with a smile.
Zhang Yanling said: "I really want to know how you solve the problem of loading and primer. You can't just load the bullets one by one, right? How is that different from a blunderbuss?"
Xu Youtang smiled mysteriously and said: "Brother, you will soon praise me for being smart."
As Xu Youtang spoke, he walked to the other side of the wooden platform, opened the lid of a wooden box about a foot in size, and took out a long list of black things from inside.
"Hehe, that's right. I got the idea from firecrackers. Since we want to shoot continuously, we naturally need to load the bullets continuously. Firecrackers can be braided together and set off, why can't bullets? So I braided the bullets together according to their size. You see,
There is a bullet pouch in the front, which is used as a gun.
The paper-wrapped bullets. This little place on the back is the primer bag. I only need to embed the bullet belt into the barrel of the gun. As it rotates, subsequent bullets can automatically embed into it as the barrel rolls. The distance in the middle is
Calculated, the distance is one inch, and it can fit into the breech."
Xu Youtang said and gestured quickly. Zhang Yanling began to admire.
"You must be wondering how the primer can ignite when it is wrapped in a paper bag at the back. That's because..."
"Wait, let me take a bold guess. There must be a steel blade cutting at the interface. When the bullet is pressed into the gun chamber and the gun chamber is in place, the small primer bag at the rear is cut open, and the primer is exposed to flint sparks.
Next. The primer is ignited, and the fuse is also ignited, and then the medicine in the front medicine bag is ignited to complete the shooting. Is that right?" Zhang Yanling said loudly.
"Oh, brother, you are so smart, that's right. There is a rising and falling steel blade behind the bullet chamber, which rises and falls with the rotation. That's what you said." Xu Youtang laughed sweetly.
Zhang Yanling was extremely excited and shocked. After hearing this, he actually understood that although the design of this machine gun was complicated, it had indeed solved several basic problems. Zhang Yanling originally thought that this was probably just a decoration, but now he doesn't think so
Think about it.
"Youtang, come here." Zhang Yanling shouted with his arms spread wide.
Xu Youtang smiled and said: "What?"
"Let me take care of you, big brother. You really surprised me. I love you so much, little girl. Come here." Zhang Yanling said with a smile.
Xu Youtang came forward with a blushing face. Zhang Yanling hugged her petite body and kissed her heavily on the mouth.
