Chapter 898
In fact, this was developed by the British Navy in 1915. The main feature of this type of artillery shell is two words - practical.
The more gunpowder it is loaded with, the greater its power will be. However, it has no requirements on the material and can be made of cast iron.
Looking at the large round hammer cannonball drawn by Wei Wu, many craftsmen began to silently imagine their own cannonballs in their minds.
However, this was only the case for some people. Another group of craftsmen were concerned about another issue, and someone soon asked about it.
"Mr. Vice President, are there any requirements for the material of the barrel when manufacturing this mortar?"
Hearing the craftsman's question, Wei Wu smiled and nodded, looking at the man with praise and said:
"I have to say, you asked a very good question. In fact, the strength requirements for the mortar barrel are very low."
"It's different from the Red Cannon. The Red Cannon has certain requirements for the barrel because it uses a solid iron cannon."
"The barrel needs to withstand an extremely strong explosion in order to convert it into enough kinetic energy to fire the solid iron cannon."
Having said that, Wei Wu pointed to the mortar shell drawn on the whiteboard.
"But the mortar's main killing power is not based on kinetic energy, but on the explosives inside it. Crucially, it is also light."
"A mortar shell weighs about seven or eight kilograms, less than half the weight of a solid iron shell."
"Besides, the mortar's range only needs to be around 500 to 600 meters, so the barrel doesn't need to withstand such a strong explosion."
This is not Wei Wu bragging. In fact, the strength requirements of the mortar for the barrel and shells are indeed shockingly low.
For example, in the Middle East in later generations, Laiyang steel pipes combined with gas tanks instantly labeled a steel pipe factory as an arms dealer.
With the metallurgical technology of the Ming Dynasty, even if Wei Wu did not exist, as long as they had the blueprints of the percussion cap and mortar.
These craftsmen can make mortars just by rubbing them with their hands, which shows how low the requirements for mortar barrel strength are.
In fact, many things could be created in ancient times. The ancients did not lack wisdom, but lacked basic knowledge and guidance.
For example, now, after listening to Wei Wu's explanation, the craftsmen can immediately understand what he said.
After finishing the explanation of the mortar, Wei Wu didn't plan to continue talking about it. After all, he had said almost everything he needed to say.
But just as he was about to move on to the next topic, a voice suddenly came from outside the door.
"Mr. Vice President, someone sent over a bottle of water and a piece of ice, saying it's what you wanted!"
Hearing this voice, Xu Miao immediately looked towards Wei Wu. He had not forgotten the true meaning of water turning into ice!
It was only when Wei Wu heard what was said outside that he remembered that he still had an experiment to do to make water turn into ice.
I had originally planned to cancel it, after all, now is the time to get down to business, and I still have to give lectures to the craftsmen next.
However, seeing the expectant look in Xu Miao's eyes, he didn't want to discourage the enthusiasm of his first student.
"Forget it, let's just treat it as a fun experiment to help students and craftsmen gain some knowledge!"
Thinking secretly in his heart, Wei Wu then shouted directly to the outside.
"This is what I want. Bring it in! Be gentle and don't shake the bottle!"
Afterwards, with the craftsmen looking slightly puzzled, someone outside brought in what Wei Wu wanted.
Everyone's eyes were fixed on the podium in front of Wei Wu, where a black insulated box was placed.
After putting the things away, the person who delivered them left, and Wei Wu turned around and looked at everyone and said:
"Next, I'm going to do a little experiment to show you what it means when water freezes. I'll explain the principle later."
Water turns to ice!!
After hearing Wei Wu's words, everyone became excited. They could finally see the vice president doing experiments again.
