Bi Liansheng, the commander of a tank regiment, at the same time, and Luo Ronggen once stayed in the same unit and knew each other very well.

"Lao Bi." Luo Ronggen said: "Come, let me introduce, these two are the ones I brought back from a machine factory, the technology is very high, the torque converter is made by them..."

While talking, he was about to introduce it, but he found that Qin Zhenhua and Wang Erzhu had actually disappeared, and after turning around, he found that Qin Zhenhua had already run to the 73 gun.

"Fortunately, what we brought here is a warhead, and if it is installed, it will have to be disassembled again." Qin Zhenhua looked at the 73 gun, and then looked at the wooden ammunition box on the side, which contained two shells, and they already knew what they were here for, so they removed the warhead in advance.

If it is a large-caliber artillery, the warhead and the propellant behind it are installed separately, such as the Soviet Union's 125 mm tank gun, which is already done like this, but the 100 mm artillery is almost always fixed.

Qin Zhenhua looked at Huang Chengcheng's launch cartridge, he was very happy, and waved his hand to Wang Erzhu: "Come, stuff our warhead in!" ”

"You kid, so anxious?" At this time, Luo Ronggen came up, and he originally introduced you, but he came over all of a sudden?

"Yes, Uncle Luo, this is the first time I've assembled a shell, well, the propellant in this, do you want to pour it out first?"

Qin Zhenhua was studying how to put the warhead in, and Bi Liansheng had already begun to study Qin Zhenhua's warhead: "Your warhead, it's very strange." What's in the middle? ”

Now, the most advanced armor-piercing projectile in China is still developed from the Soviet tank gun, and the middle part of this armor-piercing projectile is a disc-shaped butt, and now, this shape is very strange?

"Saddle-shaped buttle." Qin Zhenhua said: "This kind of butt can make the warhead more stable when it flies out and will not float. ”

In fact, after seeing it for the first time, everyone focused on the special butt, this shell, and more importantly, the warhead, after all, to penetrate the armor, relying on the warhead, our own warhead, using the hardest high-carbon steel that can be found in the factory, long and thin, in professional terms, is the length-to-diameter ratio, which is an important indicator of the armor-piercing ability of the armor-piercing projectile.

Of course, it has all been processed, and the final effect depends on the actual test launch.

"It's the front, it's like a small bowl." Bi Liansheng continued, if you look at the warhead, this butt appears is a bowl-shaped structure, which is also special, only in this way, the butt, after flying out, just can catch the wind, at a speed of more than 1,000 meters per second, the wind is quite strong, and it can immediately break the butt along the preset gap and become two halves, leaving only the bullet core to fly out, and, at the moment of flying out, it will also rotate at a small speed with the armor-piercing projectile.

Although it was the first time to assemble, Qin Zhenhua was very skilled, at this time, because of excitement, his face became red, in his chest, a heart was pounding, and the red-skinned diary had been heating in his chest.

Father, there is no problem with your design, now, let the practice prove it!

"Can I pull the gun rope?" When the assembly was completed, the shell was stuffed into the barrel of the cannon, and the angle of fire was adjusted, Qin Zhenhua couldn't hold back any longer, and said to Bi Liansheng on the side.

In this way, the safety of the gunner can be ensured to the greatest extent, and the gun generally uses a firing machine, which is equivalent to the trigger of a gun, which is installed on the left side of the gun body, and the gunner can stand next to the gun and directly pull the firing machine to fire the gun.

This is very efficient and fast, however, it is not safe.

Therefore, the artillery has a reserve way of pulling the rope to fire, especially after the artillery completes a shooting task, after the maintenance is completed, the next time the fire is fired, the first gun is the rope, in case of explosion or something, the rope can protect the safety of the gunner.

If Qin Zhenhua's father used this way at that time, there would be no problem.

Just leave one person to pull the rope, Qin Zhenhua couldn't help it, eager to try, looking at his begging gaze, Luo Ronggen asked Bi Liansheng: "Old Bi, what do you think?" ”

"Okay, young man, come on."

Qin Zhenhua pulled the rope and pulled it so hard, and then, he clearly heard the crisp clanging sound of the firing pin inside firing the primer of the cannonball, and then, boom!

The eardrums are going to be cracked! There was a buzz inside, and I couldn't hear anything clearly, only seeing a bright smile on Bi Liansheng's face, with a big mouth, I didn't know what he was talking about.

This process is actually very complicated, when hitting the primer, the propellant is quickly ignited, the high-temperature and high-pressure gas, pushing the butt, tightly attached to the barrel, quickly flying out, when it reaches the muzzle, the speed has reached more than 1,000 meters per second!

Then, the warhead flew out of the muzzle, with the high-temperature and high-pressure gas behind, quickly rushed out of the muzzle, the huge fireball, slapping the surrounding air, the air that was quickly squeezed, made this deafening sound, and then, under the fierce wind head-on, the butt broke in half and fell, leaving only the bullet core, which flew quickly to the front, flying towards the homogeneous steel target a thousand meters away.

The black smoke from the muzzle of the cannon was still rising, and the barrel of the gun, which was more than a ton, flew out with the shells and sat back for some distance, which made Qin Zhenhua a little worried, should it affect the accuracy because of this?

Qin Zhenhua's ears were still buzzing, and he couldn't hear anything, so he saw Bi Liansheng holding the walkie-talkie, not knowing what he was shouting.

Then, a surprised expression appeared on Bi Liansheng's face: "What? The target was shot through? How can it be? Our target is one hundred and fifty millimeters thick! ”

The Type 73 100 mm anti-tank gun, with only two types of armor-piercing shells and grenades, can only penetrate 100 mm of armor when using armor-piercing shells, and now, with Qin Zhenhua's warhead, other conditions remain the same, the 150 mm thick target will be penetrated?

Increases armor-piercing ability by half at once!

"It's evil, stop shooting, Lao Luo, go, go over and have a look." Bi Liansheng said as he jumped onto a Yangtze River 750 on the side and stepped on the starting lever fiercely.

Luo Ronggen's face was also extremely shocked, what? Qin Zhenhua's warhead, is there such an evil door?

"Hey, Qin Zhenhua, let's go, let's go over and have a look!" Luo Ronggen beckoned to Qin Zhenhua.
