"Hahaha, if I have to say it's worse for you, what is this? This structure in this shelf, just looking at it, makes my head hurt!"
It seemed that because he saw Keyes with the same painful expression, or even worse, Smith felt that he was no longer so uncomfortable.
"What are you laughing at? You are so happy. Did I write a joke on the drawing?"
Polu's voice suddenly came from the door.
"Ugh, I'm laughing at Case's face!"
"Is your complexion better now? Forget it, how do you look at the drawings?"
Smith quickly took out his small notebook.
"Little manager, if I read this correctly, this is the barrel of a 20mm machine gun? I think even the rifling method is the same."
Bolu looked at Smith and said, "Okay, the recent process drawings can be understood without explanation!"
"I can't always understand the drawings. It's still possible to be simple."
He showed an honest smile.
"But, this thing, it looks like four cannons are forcibly mounted on a rack? Is there any benefit to this?"
"Of course, one gun crew can control four cannons. And where is the force? The direction of the ammunition feeder has obviously been changed."
"No, I mean what's the point of such a system? After all, don't all small gunboats now have cannons on their sides? What's the difference between a few cannons and this one?"
"Didn't you hear what Pauleicht said? The life on the small gunboat, no, it can only be called the living conditions now, is too harsh. After all, when I built this boat, I never thought about letting it leave port for a long time!
"
"I am trying to think of ways to reduce the number of people on board the new ship. The projection capacity of this new equipment is so great. There are four cannons in one turret. Only a four-man gun crew can operate it, and the gun emplacement occupies a small area.
Isn’t this meaningful? With the same number of people, I can put four machine gun turrets, four times the happiness!”
After speaking, he paused and added:
"And the four cannons are controlled by one gun crew, which will definitely do a better job of concentrating firepower."
"Well, he didn't tell me these things. Is the small gunboat so crowded now?"
"Yeah. The cabin is full of black bread and hard biscuits. Now we can't get a bed for each person, and we have to take turns sleeping. It's really miserable. Otherwise, I won't be too lazy to develop new weapons if they are used properly."
"Tsk, that's too bad, I understand. But how do you launch it with this structure? One person can't control four triggers and also control the direction, right?"
"What four triggers? Just one pedal, okay? The activation method has changed this time! If you don't understand, you can ask Case? Your drawings are a set, and hey, Case, you don't know either? That means in the end
You haven’t seen the part yet?”
Bolu took two steps, flipped through the bottom part of the drawing roll, and pulled out one: "This is it. It's not difficult. You can definitely make it."
Unexpectedly, the two of them looked at each other with confused expressions on their faces.
"Forget it, it's not enough to just rely on the drawings. I think I'd better build a sample to make it more reliable for you."
Bolu sighed slightly disappointedly.
Smith and Case had a somewhat embarrassed look on their faces. They looked at each other and lowered their heads.
"Feel sorry."
"It's okay. You haven't seen this before, so you can't imagine it. It's normal. I'll make a sample for you now. There's a list of materials at the bottom of the drawing. Take it out and go find all the materials!"
Smith hurriedly went to find the workers to prepare materials. As he walked, he murmured in his heart: "You say it as if you have seen it before?"
The machinery factory was naturally well stocked with materials, and soon the reserved materials were put on small carts and transported. However, Polu decided to explain to the two of them on the drawings, so that they could at least understand what was being manufactured:
"This is the turret seat ring! This plate is the turret seat plate!"
"This is the main bracket of the turret! This one inside is called a planetary gear! Why use this? It's so strong! The recoil of the four cannons firing at the same time does not need to be supported by this method. I'm afraid the bracket will get stuck after the bracket is built! Anyway, I don't have it for the time being.
There is another way."
"This arc-shaped rack is used for high and low machines. Why is it so long? Of course it's because of the high elevation angle! The elevation angle of this gun can even shoot vertically into the sky!"
The confusion on Smith's face only became more intense: "But, what are you doing so high up in the sky? Will anything come from the sky?"
Polu: "..."
"It's hard to answer Smith's question! I know I'm afraid of being ridden in the face by a flying dragon, but how does Smith know what a flying dragon is?"
He had no choice but to find a way to fool him: "Anyway, it's just a matter of adding a section of rack, it doesn't matter."
"The gunner sits here, and the assistant gunner sits here. One is responsible for triggering, and the other is responsible for tracking. One below here, one on each side, is the ammunition hand. Do you see the grid here?"
Bolu clicked on the half-height armor of the turret.
"All the grids here are filled with loaded ammunition boxes."
After all, it is a rapid-fire cannon operated by a person, not a telex turret. In order to obtain a better field of vision, there is really no way to fully protect it.
And if the turret becomes heavier, the rotation speed will slow down, and it will naturally not be able to keep up with high-speed targets, so it can only add a gun mantlet in front.
But the magical world has a magical solution. The shield technology obtained from the captured speedboat came in handy.
The semi-automatic shield controlled by the secondary gunner is just the right size to protect the turret.
After hearing the psychological shadow caused by the torpedo boat on Hippolyte, Polu may have learned a good lesson.
All the artillery shells are in the ammunition depot, and it is too slow to send them up temporarily. If there is a sudden attack, with the speed at which the cannon eats ammunition, it may not be possible to organize effective fire interception.
For the 20-gun, the best way to feed ammunition is naturally to feed ammunition without an ammunition chain - however, Polu weighed his own weight and found that there was no possibility of realizing this delusion. The internal structure of the giant drum was completely unknown.
Take action.
So for Polu, who still has no way to create a belt-less ammunition supply system, it is natural to choose belt-fed ammunition!
Now that you have a stamping machine, it is not difficult to make a batch of ammunition chains. The only problem is what a dispersible ammunition chain looks like!
A lot of attention was paid to the weapon blueprints, but this small thing was like a blind spot. No matter how hard Bolu recalled it, he couldn't remember it. Moreover, although the thing was small, its structure was quite simple. He made many experiments without success.
It's going to be a complete mess.
In the end, I had to continue to use magazines - at least this thing can be mass-produced, and the ammunition supply rarely fails. Fortunately, the 20-gun ammunition can hold 20 rounds in a magazine, and strong gunners can even load the ammunition with one hand, easily
very!
After all, today’s sailors are all big-muscled reserves! If it weren’t for reliability, Polu would have wanted to try the double-row magazine!
After all, it is obvious that the current bottleneck in the rate of fire lies in the ammunition supply.
Shaking his head, he persuaded himself in his mind: "There is no future for high-rate weapons that rely on magazine clips! Don't just look at these people who are so strong and just want to make big magazines! You have to take time to get out the bullet chain!
Otherwise, how will we use machine guns in the future!"
"Little steward, little steward!"
"Ah, what's wrong?"
"Didn't you say you want to make a sample? You suddenly shook your head?"
"It's okay, I thought of something else. Well, you all understand the structure now, right? Is there any problem? No problem, I'll start working on it."
"I understand, but it may not be built very quickly. The gears in this bracket are a bit troublesome."
Case answered cautiously.
"Approximately how long will it take?"
"It might take three days to make one."
"That doesn't count planetary gears? I can go find a precision manufacturing company to do this."
"The speed can be improved a lot. By the way, what is this thing called?"
"Isn't it called a machine gun?"
"Then you have to give me a number, otherwise I won't be able to fill out the production form."
Keith looked innocent.
"You guys don't know that I'm very bad at naming? Then give a model number to this four-unit package, just fill in April Rain."
Polu casually reported the model number, looked at the materials in front of him and the recycled old cannon, and began to assemble it.
