On the arena.
This time, the venue of the competition was Li Yunlong's new regiment's station, which was located in a very safe place in the hinterland of the Taihang Mountains. There were sentries in the area of dozens of miles to prevent any sneak attacks by the devils.
"Chief, this is the bamboo tube mortar I developed. The cannon body is made of bamboo that can be seen everywhere. The cannonball is also very powerful and is suitable for mass production of equipment for the army.”
A tall and boorish soldier was introducing his work non-stop, causing the 386th Brigade's brigade commander, Chen Geng, and Zhou Lin to be stunned.
He saw a bamboo mortar similar to the Type 60 mortar on the ground. It looked similar, but he didn't know its performance.
Although Zhou Lin didn't know anything about machinery, his son did, so he more or less knew something about it.
If bamboo tubes could be used as mortars, would the 8th Route Army lack heavy firepower and be suppressed by the Japanese?
"You can just start. You'll know if it's a mule or a horse after you walk it for a while.”
"Yes, sir!"
Zhou Yun, who had just walked to the sidelines with Li Yunlong, was stunned. His mouth was wide open in disbelief, and his eyes were filled with confusion.
Guess what I saw?
Bamboo tube mortar, it was a bamboo tube mortar!
The bugged weapon in this anti-Japanese drama really existed. It was really an eye-opener.
Li Yunlong did not believe that this thing could kill the Japanese. He tilted his head and whispered,"Pretty boy, how far do you think this bamboo tube mortar can shoot?”
"Do you know the principle of mortars?"
？？？
If I knew, why would I ask you?
"If you tell me, won't I know?”
Zhou Yun's mouth twitched a few times. Li Yunlong's words made sense, but he couldn't refute them.
He searched through the memories of his predecessor and soon, the principle of the mortar appeared in his mind.
"Mortars are a type of gun with a short body, a large firing angle, and a high trajectory. They use a seat plate to withstand the recoil. Small and medium-caliber mortars are loaded at the muzzle, and large caliber mortars are loaded at the end. A cannon with a low initial speed and curved trajectory.”
" Now, let's talk about shells. Mortar shells slide into the barrel from the muzzle, relying on its own mass to make the shell's base fire hit the firing pin at the bottom of the barrel, or rely on its own mass to slide to the bottom of the cannon body. After the shooter releases the firing pin, it hits the base fire at the bottom of the shell.”
"After the primer is fired, it will ignite the tube at the end of the shell. Then, the gunpowder in the additional package tied to the shell will also be ignited.”
"Although there is a certain gap between the shell and the barrel to ensure that the shell will slide down, the gas ring outside the shell can still form a huge bore pressure, pushing the shell out of the muzzle and flying towards the target.”
"The launching principle of the mortar determines that the mortar shell cannot be tightly attached to the barrel, so it cannot rely on the rifling to rotate the shell to stabilize its flight direction. Therefore, the tail stabilizing device must be used to ensure its flight attitude.”
" Therefore, all mortar shells are equipped with a tail. A typical mortar shell, in addition to the tail, also includes a fuse, a detonator, explosives, a body, a gas trap, a basic explosive tube, an additional explosive charge, a primer, and other components.”
"Although this big brother's bamboo mortar's body structure is reasonable, its lifespan will definitely not exceed three rounds. As for the cannonball, it is completely unreasonable. Without a metal tail, the cannonball will not be able to fly far.”
"Do you understand?"
Li Yunlong didn't say anything. His face was full of ignorance.
Seeing this, Zhou Yun could not help but pat his head in frustration. He hated himself for being too stupid.
He was actually trying to explain to an illiterate like Li Yunlong. Wasn't he playing the lute to a cow?
A few seconds later, Li Yunlong came back to his senses. He didn't understand a single word that Zhou Yun said just now, but he couldn't lose face.
"Yes…I understand!"”
"What do you understand?"
"That stupid donkey's bamboo mortar can't kill the devils.”
“……”
" I'm too naive." Zhou Yun took a few steps to the side in disdain. He wanted to stay away from this illiterate. It was tiring to talk to him.
In the arena.
The soldier was also ready to fire. Under the gaze of hundreds of pairs of eyes, he confidently stuffed the shell into the barrel.
Bang ~
A muffled sound made everyone hold their breath. Their gazes followed the trajectory of the artillery shell in the air.
Ten meters!
Twenty meters!
Thirty meters!
4...35 meters!
Hong ~
The shell landed on the ground about 35 meters away and exploded. The power... Well, it was not even as powerful as a grenade.
"F * ck, this is not even as far as my grenade. It's completely the same as taking off your pants and farting!”
Li Yunlong felt insulted and couldn't help but comment.
The onlookers were not any better. They closed their eyes in pain, and some even shed a few tears.
I can be punished according to military rules if I do something wrong. Why did you send him to hurt my eyes?
The brigade commander and Zhou Lin looked at each other and silently raised their red cards.
"Bureau Chief, actually, my bamboo tube mortar…"
