"Huang..." When the car stopped in front of the target, an old man got out from behind. Seeing the old man, Bi Liansheng and Luo Ronggen were about to shout in surprise, but the old man waved his hand to signal them to stop talking, and then became very interested.
He said quietly: "Well, I just finished a meeting today. Come and see how this new armor-piercing bullet performs?"
After saying that, he walked to the target, looked at the molten opening on it, and immediately took a breath: "This, is this made by our armor-piercing projectile?"
The old man has worked in the armored force for decades, and of course he has trust in the level of his own equipment. Now, when he sees this penetration, he absolutely cannot believe his eyes. Among us, what kind of equipment can penetrate so deeply?
"Yes, uncle, this is the armor-piercing bullet plan designed by my father. His plan is completely feasible." Qin Zhenhua said to the old man.
Qin Zhenhua also recognized it. This old man was the same old man he met in the maintenance workshop last time. He was also the old man who appeared in his father's photo. He must have a lot to do with his father. No matter who he was, Qin Zhenhua
You have to tell me this. This armor-piercing bullet plan was designed by my father. His plan is completely feasible and can effectively improve your own effective penetration!
The old man nodded: "Yes, that's right. It finally succeeded. Okay. From now on, our army will have peace of mind. By the way, have you tried it on a tank?"
"Not yet. Let's do another experiment tomorrow." Seeing that after all this tinkering, it was already afternoon. In order to prevent accidents, it would be better to leave the test until tomorrow morning, so Bi Liansheng said.
The old man nodded: "Okay, if I have time tomorrow, I will come over and have a look. Well, Xiao Qin, yes, we have solved the big problem of our armored forces. Come on, get in my car and take you to the headquarters for something delicious.
of."
"Okay, sir." Qin Zhenhua was really polite and greeted Wang Erzhu. Bi Liansheng and Luo Ronggen went straight to the headquarters of the training ground. This was the first time to ride 212. It was indeed much more comfortable than tractors and cars.
!
The small stove in the headquarters is not bad, especially there is a roasted whole lamb in the middle of the table. This is a rare meal!
"You are here today. It just so happens that the troops went out hunting and the harvest was good. Otherwise, there would be nothing good to entertain." Commander Huang said cheerfully.
In recent years, the troops on the grasslands often go out hunting, driving their cars, and encountering yellow sheep and the like. The sudden bursts are enough to eat a few meals.
"I had an idea when I was just now." 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 then add a pulley on the top of the turret to pull the rope.
Just pull out the rope, won’t it be enough?”
When Qin Zhenhua said this, several people immediately realized, yes, why didn't we think of it? Testing the gun in this way greatly increases safety. Even today, there is no need to test the 73 gun at all, and we directly find a 69 tank to test fire.
That’s it.
"Xiao Qin, this is a good idea of yours!" Upon hearing Qin Zhenhua's words, Bi Liansheng immediately realized, yes, it is so safe!
At that time, if Old Qin had such a clever trick as Xiao Qin...well, how could he have known it at that time!
"Xiao Qin, how sure are you of tomorrow?" The old man was also very happy today. He entertained a few of them, especially Qin Zhenhua, and also took out a bottle of good wine. Amidst the tangy aroma of the wine, the old man drank it down in one gulp, and then asked Qin Zhenhua
asked.
At that time, the T-62 brought such a shock to the domestic army that all kinds of weapons could not penetrate it. Even in the shock, there was a trace of despair. Although a large number of weapons were developed, none of them were really usable.
Not many, until today, the new armor-piercing bullets processed by Qin Zhenhua have doubled the armor-piercing ability at once. The old man was very happy today, drinking wine, and looking forward to what surprises Qin Zhenhua could bring to them tomorrow.
"According to my father's calculations, if it is placed on our 100mm slide, the armor-piercing capability should be able to reach 250 millimeters." Qin Zhenhua said: "And according to today's experimental results, the accuracy can also reach the standard of our rifled gun.
.”
Two hundred and fifty millimeters, this data is very meaningful. In the future, when our own 69 tanks compete with T-62 tanks, there is absolutely no need to be afraid.
However, now there are not only T-62s on the opposite side, but also more advanced T-64s and even T-72 tanks. These tanks have thicker armor.
In fact, throughout the 1960s and 1970s, the domestic tank force was in such a desperate situation. It was impossible for our own tank guns to penetrate the opponent's main armor. If a war really broke out, we could only rely on brave men.
With a fearless spirit, he rushed forward to surround the opponent, then circled behind the opponent and opened fire.
I don’t know how many tanks will be blown up by the opponent during the charge, but there is no way. If the equipment is not good, we can only rely on human lives to fill the gap.
Now, there is finally hope.
"So, can the armor-piercing ability be further improved?" the old man continued to ask.
"Of course." Qin Zhenhua said: "It's just that the price is more expensive. If we can have tungsten alloy as the core of the armor-piercing projectile, the armor-piercing capability can reach 300 millimeters."
Armor-piercing bullets are head-to-head. Ordinary steel-core bullets were widely used by the Soviets only because they were cheap. If you want to have greater penetration, you have to start with materials, and tungsten alloy is recognized as the most
Suitable material for the core of armor-piercing projectiles.
Of course, this thing is even more expensive. If a steel-core warhead costs several hundred yuan, then a tungsten alloy warhead costs several thousand or even tens of thousands of yuan!
Can the army afford it?
Several people were stunned for a moment, and then Luo Rongen broke the silence first: "Do we have any alternative? For example, the warhead of the armor-piercing projectile is made of tungsten alloy, and the body of the rear projectile is made of ordinary steel. Anyway, we are responsible
The armor-piercing part is the warhead part.”
Qin Zhenhua shook his head: "Of course it's not good. A whole bullet core can be processed directly on a CNC machine tool, and the accuracy can meet the requirements. How to connect the two parts when they are separated? If welded, the strength cannot be guaranteed, and the bolts
If connected, accuracy cannot be guaranteed.”
It is very difficult to weld two different materials together. Armor-piercing projectiles are used to drill holes in tanks. If the projectile breaks during the process of drilling holes, will it still be effective?
Without welding, you can only add a cylinder liner to the outside and clamp different materials together. The accuracy cannot be guaranteed. Even if the center of gravity of the bullet core deviates slightly, it will have a great impact on the flight of the bullet core.
The impact ultimately caused the projectile to float and fly out with insufficient accuracy.
"Now, the West has begun to use tungsten alloy as the main material of bullet cores." Qin Zhenhua said: "Our country has the richest tungsten ore in the world, why should we be stingy on it? For tank soldiers, what exactly is it?
Is the cost of artillery shells more important, or the ability to penetrate enemy tanks?"
The old man nodded: "That's right, let others worry about the cost. We tank soldiers want the strongest equipment. Xiao Qin, I will apply for tungsten alloy materials for you and leave the processing to you.
The test is here with us! Three hundred millimeters, well, with a penetration depth of three hundred millimeters, what are we afraid of? By the way, is there still potential that can be tapped?"
