Zhu Jingyuan arranged the armor formula and went to the Ordnance Department to find someone from the Artillery Design Bureau.

Li Rui, the director of the Ordnance Division, happened to have returned from the test site in the suburbs, and when he heard that Zhu Jingyuan was coming to find someone, he immediately followed him to see the situation.

Zhu Jingyuan saw that the familiar Li Rui was back, so he simply didn't go to the people from the Artillery Bureau.

The artillery design bureau is similar to the armor design bureau, and many craftsmen have stayed in the factories of the new city for a long time, tossing the production process of various artillery and shells on the spot.

Most of the personnel in the yamen of the Ministry of Industry are left-behind and docking personnel.

Since you have to find someone to dock and convey, it is the same to directly let Li Rui dock.

Zhu Jingyuan asked Li Rui to find a small conference room, and after the two sides sat down, they first asked about their situation:

"Director Li, whether the naval gun turret designed by the Artillery Bureau is a saddle gun, that is to say, the two and three gun barrels in the turret can only be raised or lowered at the same time."

Li Rui recalled the content of the report of the Artillery Bureau:

"Some craftsmen mentioned this design, saying that it could reduce the structural complexity of the triple turret and reduce the overall weight of the turret.

"The side effects of this are to be expected, the shooting accuracy will definitely be reduced, is Your Highness going to support this design?"

Zhu Jingyuan waved his hand very decisively and said:

"No, I'm just specifically reminding you not to design it that way as much as possible, especially with the large-caliber guns of battleships."

There are many common saddle guns in history, such as the battleships Nevada and Oklahoma of the Americans, as well as the Cleveland-class and Brooklyn-class light cruisers.

The common saddle gun also had some advantage in fire density on light cruisers, which was almost meaningless on battleships pursuing a large range.

If the main artillery is repeatedly fired on the battlefield, and the shells are always drawn around the target, that is, they will never hit the target, and it will definitely make the blood pressure of the commanders rise.

Li Rui used his notebook to write down Zhu Jingyuan's requirements:

"Understood, I'll tell them not to engage in a communist saddle cannon at the next meeting, in fact, I don't agree with it myself, do you have any other requirements from Your Highness?"

Zhu Jingyuan tilted his head and thought about it:

"Others, it seems, are not particularly important, that is, the shells should be as heavy as possible, the speed should be as high as possible, and the development of larger caliber guns should begin in advance.

"Oh, yes......"

Zhu Jingyuan suddenly reacted:

"Quilt cap - what is the material of the shell's quilt cap now? Is there a case-hardening process like armor steel? ”

The fourth-generation armor of the Ming Dynasty, after the application of case hardening technology, the tip of the shell is easy to be crushed by the armor.

So much so that the shells could not penetrate the armor and were directly scrapped, as a result, the battleship's main guns could not penetrate the cruiser's armor.

At one time, the capital ship was embarrassed to the extreme, and the cruiser became bigger and bigger.

But the craftsmen slowly found a way to cope.

They made a rounded and blunt "hat" out of a tough metal material, which was welded to the top of the head of the armor-piercing warhead.

In this way, when the shell hits the armor, the cap touches the armor first, which is equivalent to installing a cushion.

In this way, the warhead of the armor-piercing projectile is protected from being crushed by the surface layer of the armor.

At the same time, the quilt cap can also play the role of rubber on the sole, so that the shell will not slip when it is hit at an angle.

Resistance can righte the slanted shell, which allows for better armor piercing.

This kind of armor-piercing bullet with a hat is called a cap-piercing bullet.

With the cap-piercing shells, the capital ship was finally able to bully the cruiser, and the protective armor of the battleship was thickened again.

But Zhu Jingyuan knew that the cannonball simply had a quilt cap, so that the tip of the cannonball would not be broken again, which was still not the limit of the quilt.

It can also "treat others the way they do".

The coat is made using the carburizing and hardening process of the armor, which in turn shatters the hardened layer of the armor.

Apparently no one in the world has done that yet.

When Li Rui heard Zhu Jingyuan's question, he was also a little surprised, and shook his head directly and said:

"There is no case hardening process, just a quilt hat made of ordinary alloy steel, Your Highness means...... Do you apply the surface carburizing and hardening process to the quilt cap? ”

Zhu Jingyuan smiled and nodded:

"Yes, we can try, enlarge the quilt cap at the same time, because using the carburizing and hardening technology of the surface of the armor, try to use it to break the hardened layer of the armor.

"Without a hardened surface, the fifth-generation armor becomes ordinary homogeneous armor with a significantly reduced thickness, which should increase the armor-piercing ability of the projectile.

"Of course, in order to prevent the cannonball itself from being shattered, the material and production method of the cannonball must also be optimized, and it is the task of the craftsmen to do exactly how to do it."

Li Rui understood Zhu Jingyuan's intentions, and immediately imagined the effect of this operation, so he couldn't help but show a surprised expression:

"I'm going to get someone to do the test right away! Modified shell tests can be done right away! ”

Zhu Jingyuan thought about the task of peace talks, they should not be able to do it before they left, but they can send it over after they are done.

"Do it as soon as possible, produce a batch as soon as it is done, and send it to the Western Cape by cargo ship, maybe the negotiation process can be used."

Li Rui immediately understood Zhu Jingyuan's intentions, a new type of armor-piercing shell that can shatter the hardened surface layer can definitely form a good deterrent effect.

This effect may even be better than that of aircraft, since now aircraft are temporarily unable to inflict a fatal blow on a battleship, but a new type of armor-piercing projectile can.

Li Rui solemnly agreed again:

"I'm going to urge everyone to get it out as soon as possible."

Zhu Jingyuan thought about it for a while, recalled the situation related to the armor-piercing bullet, and reminded Li Rui again:

"By the way, a larger cap will better protect the tip of the projectile, but it will increase the flight resistance of the armor-piercing projectile, which in turn will make the range of the shell shorter.

"So we can add a pointed hollow shell to the outside of the quilt hat.

"To make the shell sharp again, it can be sharper than the original ordinary armor-piercing shell, and the speed of the shell should be increased again.

"Referring to the previous quilt cap, I call this shell a 'hood'.

"The hood is hollow, and it should be gone when you touch it, and it shouldn't affect the armor-piercing effect, but the actual effect still has to be tested."

Li Rui now just nodded and agreed:

"Well, great, Your Highness's ideas are very valuable, although they have not been directly tested, but they will definitely be useful when you can imagine.

"I'll let people test it as soon as I get back, does Your Highness have any other requirements?"

Zhu Jingyuan sorted out his thoughts again:

"Yes, yes, you have to find a way to design a cannonball that will cause flames when it hits something, and a bullet from a machine gun.

"You can try adding materials like white phosphorus.

"These shells and bullets, which were mounted on anti-aircraft guns and airborne machine guns, were mainly used to attack enemy airships.

"First use ordinary bullets to penetrate the airship, let the hydrogen in the airship's airbag leak out, and then use incendiary bombs to ignite the hydrogen gas.

"This will turn the airship into a burning gas canister.

"If you make it, remember to send it to the Western Cape for testing."

Li Rui imagined that scene a little, and he subconsciously gasped.

If these bullets and shells were made, combined with Zhu Jingyuan's operational ideas, the airship would be completely abandoned.

Li Rui could only restrain his mind and quickly write down these requirements.
