"Huang..."When the car stopped in front of the target, an old man came down from behind, and when he saw the old man, Bi Liansheng and Luo Ronggen were about to shout in surprise, but the old man waved his hand, signaled the two to stop talking, and then said with interest: "Well, I just finished a meeting today, come and see, how is the performance of this new armor-piercing bullet?" ”

After speaking, he walked to the front of the target, looked at the opening above in a molten state, and immediately took a breath: "This, this is our armor-piercing bullet?" ”

The old man has been working in the armored forces for decades, and of course he can trust the level of his own equipment, but now, seeing this penetration, he absolutely can't believe his eyes, we ourselves, what kind of equipment can fight so deep?

"Yes, uncle, this is the armor-piercing projectile scheme designed by my father, and his plan is completely feasible." Qin Zhenhua said to the old man.

Qin Zhenhua also recognized it, this old man, the old man he met in the maintenance workshop last time, and the old man who appeared in his father's photo, must have a great relationship with his father, no matter who he is, Qin Zhenhua has to tell this matter, this armor-piercing projectile plan was designed by his father, his plan is completely feasible, and it can effectively improve his own effective penetration!

The old man nodded: "Yes, yes, it finally succeeded, okay, in the future, our troops will be reassured, by the way, have you tried it on the tank?" ”

"Not yet, let's experiment again tomorrow." Seeing that after such a lot of tinkering, it was already afternoon, and in order to prevent accidents, it would be better to leave the test gun until tomorrow morning, so Bi Liansheng said.

The old man nodded: "Okay, if I have time tomorrow, I'll come over and take a look, well, Xiao Qin, yes, it's a big trouble for our armored troops, go, get in my car, and take you to the headquarters to eat something delicious." ”

"Okay, uncle." Qin Zhenhua was really polite, greeted Wang Erzhu, Bi Liansheng and Luo Ronggen together, and went straight to the headquarters of the exercise ground, this is the first time to take 212, and it is really much more comfortable than a tractor and a car!

The small stove in the headquarters is not bad, especially in the middle of the table, there is a roasted whole sheep, this is a rare meal!

"You came today, just as the troops went out to hunt, and the harvest was good, otherwise, there would be nothing good to take out to entertain." Commander Huang said happily.

In recent years, the troops on the grassland often went out to hunt, drove a car, and encountered yellow sheep and the like, which was enough to eat a few meals for a while.

"I just had an idea." Qin Zhenhua said: "Our 73 gun can pull the rope, in fact, our tank gun can also pull the rope." Just tie the trigger and add a pulley to the top of the turret and pull the rope out, isn't it? ”

As soon as Qin Zhenhua said this, several people immediately reacted, yes, why didn't we think of it? In this way, the safety of the test gun has been greatly increased, and even today there is no need to experiment on the 73 gun at all, just find a 69 tank to test fire.

"Xiao Qin, this idea of yours is good!" As soon as he heard Qin Zhenhua say, he immediately reacted, yes, how safe it is!

At that time, Lao Qin, if there was such a clever trick as Xiao Qin... Alas, who knew at the time!

"Xiao Qin, how sure are you tomorrow?" The old man was also very happy today, entertained a few of them, especially Qin Zhenhua, and took out a bottle of good wine, in the fragrant aroma of wine, the old man drank it all, and then asked Qin Zhenhua.

At that time, the T-62 brought too much shock to the domestic army, all kinds of weapons could not penetrate it, and even in the shock at that time, there was a trace of despair, although a large number of weapons were developed, but not much can really be used, until today, the new armor-piercing bullet processed by Qin Zhenhua has doubled the armor-piercing ability at once, the old man is very happy today, drinking wine, and looking forward to tomorrow, what other surprises can Qin Zhenhua bring them.

"According to my father's calculations, if put on our 100 slips, the armor-piercing capacity should be able to reach two hundred and fifty millimeters." Qin Zhenhua said: "And according to the results of today's experiments, the accuracy can also reach the standard of our rifled guns." ”

Two hundred and fifty mm, this data is very meaningful, and in the future, when your own 69 tanks and T-62 tanks face off, you definitely don't have to be afraid.

However, now there are not only T-62s on the other side, but also more advanced T-64s, and even T-72 tanks, which are more heavily armored.

In fact, throughout the sixties and seventies, the domestic tank troops were in such a desperate situation, and it was impossible for their own tank guns to penetrate the opponent's main armor, and if war really broke out, they could only rely on the fearless spirit of the brave to rush up and surround the opponent, and then go around the opponent's rear and open fire.

I don't know how many tanks will be blown up by the opponent in the process of charging, but there is no way, the equipment is not good, so it can only be filled by human life.

Now, there's finally hope.

"So, can the armor-piercing ability be further improved?" The old man continued.

"Absolutely." Qin Zhenhua said: "It's just that the price is more expensive, if we can have tungsten alloy to make the core of the armor-piercing bullet, the armor-piercing capacity can reach 300 millimeters." ”

Armor-piercing bullet is a hard-hitting, ordinary steel core bullet, only because of the cheap cost, it was widely used by the Soviets, if you want to have a greater penetration, you have to start from the material, and tungsten alloy is recognized as the most suitable material for the core of armor-piercing bullet.

Of course, this thing is even more expensive, if you say that the steel core warhead is a few hundred yuan, then the tungsten alloy one will cost a few thousand, or even tens of thousands of dollars!

Is it used by the troops?

Several people froze for a moment, and then, Luo Ronggen broke the silence first: "Do we have a flexible way?" For example, the warhead of the armor-piercing bullet is made of tungsten alloy, and the rear projectile body is also made of ordinary steel. ”

Qin Zhenhua shook his head: "Of course it's not good, a whole elastic core can be directly processed on the CNC machine tool, and the accuracy can meet the requirements. In the case of welding, the strength cannot be guaranteed, and in the case of bolting, the accuracy cannot be guaranteed. ”

It is very difficult to weld two different materials together, armor-piercing shells are used to drill holes in tanks, and if in the process of drilling holes, the body of the projectile breaks, is there still an effect?

If you don't weld, you can only add a cylinder liner outside, and clamp different materials together, and the accuracy can not be guaranteed, even if the center of gravity of the bullet core deviates slightly, it will also have a great impact on the flight of the bullet core, and finally cause the missile body to float and fly out with insufficient accuracy.

"Now, the West has begun to use tungsten alloy as the main material of the bullet core." Qin Zhenhua said: "Our country has the richest tungsten ore in the world, why should we be stingy on this? Is it the cost of the shells that is important to the tankmen, or is it the tanks that can penetrate the enemy that are important? ”

The old man nodded: "That's right, the cost problem, let others worry about it, we tank soldiers, what we want is the strongest equipment, Xiao Qin, I will apply for tungsten alloy materials for you, the processing will be handed over to you, and the test will be here!" Three hundred millimeters, well, with three hundred millimeters of penetration, what are we afraid of? By the way, is there still potential to be tapped? ”
