The original pity on Xia Li's face disappeared, and he nodded happily, "Tsk, thank you I can't make it. Otherwise, how frustrating would it be to not be able to exchange money?"
A market where you can't buy and sell freely is really boring. It would be nice to give you a bonus of several thousand, but you can't even attract investment!
Wen Shuyu, who pretended not to hear anything and took a sip from the teacup, said: ...If the leader hears this, he will probably take you to the office and scold you for half an hour!
Liu Shaoying saw that the two of them had almost finished discussing energy. He came over with a piece of paper and frowned and said to Xia Li: "Our modified version of the small close-in defense gun is basically completed, and the speed is as fast as we predicted before. There's not much difference.
But I see you said you want to use armor-piercing bullets? Why not use ordinary cannonballs?
If it were really fired like this, it would be 3,600 rounds per minute. If we produced it ourselves, it would be a waste of money. We only use ordinary shells, and South Island should have a lot of stocks. "
That's what zero-yuan shopping is like. You don't feel anything when you don't have contact with it. Once you have contact with it, you will become very addicted.
After this period of research, the people in Research Room No. 2 are no longer thinking about what they are researching on this modified ship. They can do whatever they can without spending any money.
This also succeeded in causing Liu Shaoying, who originally thought there was no problem, to be particularly surprised when Xia Li wrote that the ammunition for the close-in defense artillery should use armor-piercing bullets.
Because so far, the South Island does not have armor-piercing bullets with a caliber as small as theirs, and the ammunition Xia Li drew is obviously different from the current armor-piercing bullets. This thing will cost them their own money.
Xia Li shook his head and decisively refused: "The biggest military advantage on this ship is the two close-in defense guns. If we can't make it to the extreme, the modification of this ship will be meaningless.
No matter the range or ammunition, you can't be careless.
Ordinary ammunition will produce fragments after exploding. If the two ships are too close, our ship will be damaged by the aftermath of the explosion, and the gain will not be worth the loss.
Armor-piercing bullets have strong penetrating ability and are easier to destroy the opponent's armor. This can not only destroy the opponent's ships, but is also safer for us. "
After listening to Xia Li's words, Liu Shaoying felt that it made sense, but she also felt that it was a bit overwhelming.
If you are afraid of being affected, you can fire from a slightly farther distance. There is no need to use expensive armor-piercing bullets.
As if reading his thoughts, Xia Li continued: "This new type of armor-piercing bullet is different from the previous armor-piercing bullets.
When the previous armor-piercing projectiles were fired, the shells would spin along the rifling under the action of gunpowder gas to achieve a stable effect, relying on strong kinetic energy to break through the armor head-on.
But this form has a fatal weakness, which is that it is prone to ricochet. "
The vibrating egg was hit, but it collapsed. It failed to penetrate the armor and only made a hole.
Xia Li pointed to the new type of armor-piercing bullet and pointed out the structure to Liu Shaoying. "After the sub-caliber armor-piercing bullet is ejected from the chamber, centrifugal force is used to throw away the bullet holder, leaving only the core of the bullet to fly towards the target, concentrating all the kinetic energy on the sharp On the core, the armor-piercing power is greatly improved.”
After all, Liu Shaoying is an expert in the field of weapons. She didn't care before and just thought it was inappropriate. But after hearing about the changes that this improved armor-piercing bullet would bring, the look on her face immediately became serious.
“Theoretically speaking, it is indeed more practical and more powerful than the old-fashioned armor-piercing bullets.
But in this case, there are higher requirements for the hardness of the bullet core, and copper core or ordinary alloy should not be enough. "
Xia Lixin said that she is worthy of being specialized in this industry, and the questions raised are accurate.
He nodded decisively in agreement, "It's really not possible.
The core shape of this kind of bullet is similar to that of a dart. It relies on the tail to stabilize in the air and relies entirely on head-on collision to penetrate armor. The material requirements are indeed relatively high.
So I want Grandpa Wu to study and use tungsten, which is hard and ductile, to make an alloy to increase the hardness.
Our funds can be used on this part.
As for future ammunition reserves..."
Xia Li smiled and looked at Liu Shaoying, who was still in shock, with a sly and confident look on his face. "As long as our ship has sailed to Shanghai for a fight, I believe that our country will be able to mass-produce this kind of ammunition in the future."
