Bi Liansheng, the commander of a certain tank regiment, and Luo Ronggen once stayed in the same unit and were very familiar with each other. Today, I received news that Luo Ronggen was here to take people to test the artillery, and he was waiting early in the morning.
"Lao Bi." Luo Ronggen said: "Here, let me introduce you. These two people I brought back from the No. 1 Machinery Factory are highly skilled. They made the hydraulic torque converter..."
While talking, he was preparing to introduce, but found that Qin Zhenhua and Wang Erzhu had disappeared. After walking around, he found that Qin Zhenhua had already run to the 73rd Cannon.
"Fortunately, what we brought here is a warhead. If you install it, you have to disassemble it again." Qin Zhenhua looked at the 73 cannon and then at the wooden ammunition box beside it. There were two shells in it, and they had already
Knowing what we were here for, we dismantled the warhead in advance.
Removing the warhead of an artillery shell is a technical job. If it is a large-caliber artillery, the warhead and the propellant behind it are installed separately. For example, the Soviet Union's 125mm tank gun has already done this, but the 100mm
Artillery is almost always custom-installed.
Qin Zhenhua looked at the yellow-orange propellant cartridge and was very happy. He waved to Wang Erzhu: "Come on, put our warhead in it!"
"You kid, are you in such a hurry?" At this time, Luo Ronggen came up. He originally introduced you, but he came over all of a sudden?
"Yes, Uncle Luo, this is my first time assembling a cannonball. Well, do you want to pour out the propellant inside first?"
Qin Zhenhua was studying how to put the warhead in. Bi Liansheng had already begun to study Qin Zhenhua's warhead: "This warhead of yours is very strange. What's in the middle?"
Nowadays, the most advanced armor-piercing projectiles in China are developed from Soviet tank guns. The middle part of this armor-piercing projectile is a disc-shaped bullet holder. But now, this shape is very weird?
"The saddle-shaped bullet holder." Qin Zhenhua said: "This type of bullet holder can make the warhead more stable when flying out and will not float."
In fact, after seeing it for the first time, everyone focused their attention on the special bullet holder. This artillery shell, and more importantly, the warhead. After all, it is the warhead that penetrates armor. Our own
The warhead is made of the hardest high-carbon steel that can be found in the factory. It is long and thin. In professional terms, it is the aspect ratio, which is an important indicator of the armor-piercing ability of an armor-piercing projectile.
Of course, after everything is processed, the final effect still depends on the actual test firing.
"This is the front, it looks like a small bowl." Bi Liansheng continued. If you look at the bullet, you will see that the bullet holder has a bowl-shaped structure. This is also specially made. Only this way, after the bullet holder flies out,
, just enough to catch the wind. At a speed of more than a thousand meters per second, the wind force is quite strong. It can immediately break the bullet holder along the preset gap and break it into two halves, leaving only the bullet core.
It flies out, and at the moment of flying out, it will also spin at a small speed with the armor-piercing bullet.
Although it was his first time to assemble it, Qin Zhenhua was very proficient. At this time, his face turned red due to excitement. A heart was beating in his chest. The red leather diary kept beating.
They all feel hot inside the chest.
Father, there is absolutely no problem with your design. Now, let practice prove it!
"Can I pull the gun rope?" After the assembly was completed, the shells were stuffed into the barrel, and the firing angle was adjusted, Qin Zhenhua couldn't bear it anymore and said to Bi Liansheng who was standing aside.
Using this method, the safety of the gunner can be ensured to the greatest extent. Artillery generally uses a trigger, which is equivalent to the trigger of a firearm and is installed on the left side of the gun body. The gunner can stand next to the gun and directly pull the trigger to fire the gun.
This is very efficient and fast, but it is not safe.
Therefore, artillery has a backup method of pulling a rope to fire. Especially after the artillery completes a shooting mission and is maintained, the next time it is fired, the first gun is pulled by a rope. In case of explosion or something, the rope can protect it.
Gunner's safety.
If Qin Zhenhua's father had used this method at that time, there would have been no problem.
Only one person was left to pull the rope. Qin Zhenhua couldn't help it anymore and was eager to give it a try. Looking at his begging eyes, Luo Ronggen asked Bi Liansheng: "Old Bi, what do you think?"
"Okay, young man, come on."
Qin Zhenhua pulled the rope and pulled hard, and then he clearly heard the crisp ding of the firing pin inside firing the primer of the shell, and then, boom!
My eardrums were about to burst! There was a buzzing inside and I couldn't hear anything clearly. I could only see the bright smile on Bi Liansheng's face and his mouth wide open. I didn't know what he was talking about.
This process is actually very complicated. When it hits the primer, the propellant is quickly ignited. The high-temperature and high-pressure gas pushes the bullet holder, tightly fits the barrel, and flies out quickly. When it reaches the muzzle,
By that time, the speed had reached more than one thousand meters per second!
Then, the warhead flew out of the muzzle, followed by the high-temperature and high-pressure gas behind it, quickly rushed out of the muzzle. The huge fireball slapped the surrounding air, and the rapidly squeezed air made this deafening sound.
Then, under the fierce wind, the bullet holder broke into two halves and fell down, leaving only the bullet core, flying quickly forward, towards the homogeneous steel target one thousand meters away.
The black smoke from the muzzle was still rising. The one-ton gun barrel moved back a certain distance as the shells flew out, which made Qin Zhenhua a little worried. Could it affect the accuracy?
Qin Zhenhua's ears were still buzzing and he couldn't hear anything. Then he saw Bi Liansheng holding a walkie-talkie and shouting something.
Then, Bi Liansheng's face showed a surprised expression: "What? The target was penetrated? How is that possible? Our target is 150 millimeters thick!"
The Type 73 100mm anti-tank gun has only two types of ammunition: armor-piercing bullets and grenades. When using armor-piercing bullets, it can only penetrate 100 mm of armor. But now, with Qin Zhenhua’s warhead, other conditions remain unchanged.
How about punching through a 150mm thick target?
The armor-piercing ability was increased by half in one fell swoop!
"It's evil, stop shooting, Lao Luo, let's go over and have a look." Bi Liansheng said as he jumped onto a Yangtze 750 nearby and stepped on the starter lever hard.
Luo Ronggen's face was also extremely shocked. What? Qin Zhenhua's warhead is so evil?
"Hey, Qin Zhenhua, let's go and take a look together!" Luo Ronggen waved to Qin Zhenhua.
