Anyway, they only have one gun position shooting at the shooting range today, so there is no need to worry about accidental damage. Otherwise, you must be careful when going to see the target. After the establishment of the training ground here, accidents happen every year. Of course, the troops
There is danger to begin with, and there is data such as casualty indicators.
Now, several people got on their motorcycles and bumped towards the target. No one said anything, and there was an urgency in their hearts to go and have a look, go and have a look!
This is the first time he rides a motorcycle, especially if he is riding a motorcycle. Qin Zhenhua would normally have a wonderful experience. Now, he is also filled with a feeling of urgency in his heart. What's going on?
The breakdown is definitely a breakdown, so is there any excess potential? How is the accuracy?
His ears were still rumbling, and various thoughts kept popping up in his head, making Qin Zhenhua feel for the first time that his brain was not working hard enough.
Finally, he came to the front of the target. The target reporter, who was originally squatting in the bunker under the target, also came up and said to several people: "Our artillery shells are too evil!"
He couldn't believe his eyes. The target was made of standard homogeneous steel, with a thickness of 150 millimeters. Because their original armor-piercing projectiles could only penetrate 100 millimeters, so it was said that they could safely leave the shells on the target.
Up.
What now?
A hole has appeared in the target of homogeneous steel. The front is relatively large and in a molten state. You can even see an iron slide underneath. The thin rod of the armor-piercing projectile has completely penetrated the target, although there is a comparison left behind.
The bullet holes were small, but the bullets were not retained.
In other words, the purpose of perfectly penetrating armor has been achieved!
If it pierces the target, it will have no power. The goal of this kind of armor-piercing bullet is to penetrate the armor and then penetrate into the inside of the tank. As long as it bounces back and forth inside the tank several times, it can turn the inside of the tank into a bloody mess.
When the warhead collides with the target, the high temperature even melts the surface of the target. You can see that the distance from the crosshair in the center of the target is about ten centimeters. This kind of accuracy is already quite high!
"Keep this target for reporting to the superiors." Bi Liansheng said, "Now, change to a target two hundred millimeters thick, and let's continue the experiment!"
Originally, Bi Liansheng didn't attach much importance to this mission. It was only because of Luo Rongen's relationship that he came to participate in person. Unexpectedly, this shot made him look at it differently.
He knows the performance of the Type 73 100mm smoothbore gun very well, and it will never be as outrageous as it is now!
But now, just by changing the warhead, a qualitative leap has been achieved, which is of great significance to the entire army!
Two hundred millimeters thick, can it be penetrated?
Qin Zhenhua was also extremely excited at this time. Father, there is no problem with your design. The shell just now was successfully launched without exploding the barrel, and the performance can be greatly improved!
That accident was not my father's responsibility at all, but there was another reason. For this reason, we should start investigating when we get back!
During the process of assembling the second shell, Bi Liansheng became serious and observed Qin Zhenhua's operations. At this time, he finally figured out the way.
"This warhead of yours looks very thin!"
"Yes, according to the latest theory, if you want to obtain higher armor-piercing ability, you must increase the aspect ratio of the warhead." Qin Zhenhua said: "The thinner and longer the warhead, the stronger the armor-piercing ability.
, the diameter of my warhead is only half the diameter of the original warhead."
The armor-piercing bullets of the Soviet Union are all thick and big. It looks like a small rocket when carried. It is thick in the middle and thin on both sides. I don’t know what they think. Is it for aesthetics? Or is it aerodynamic considerations when flying out?
?
No need for anything else, just a long pole with a pointed head, just like a javelin, is enough, and there must be wings at the tail to maintain stability, that's enough!
"I'll fire this cannon." After re-aiming accurately, Bi Liansheng pressed the trigger with his own hands. The moment the cannon fired, he opened his mouth. This is one of the basic movements of an artilleryman, which can balance the inside and outside of the eardrum.
Poor to prevent eardrums from buzzing.
"Target reporter, report the situation." After Bi Liansheng called out, he took the wireless telegraph phone and continued talking to the other party.
"Report, our target has been penetrated again!"
What?
Two hundred millimeters! The 200 millimeter target was actually penetrated? What an incredible artillery shell is this?
At that time, in order to tap the potential of 85 mm, a certain factory developed a "cylinder-type tail-stabilized micro-rotation armor-piercing projectile", which only reached the 120-mm armor-piercing capability, which was already a limit. But now, this seems to have a structure
A simpler artillery shell can actually be so powerful?
The gangster moved in front of the target again, and saw that the target, which was made of thick, homogeneous steel, was completely penetrated, leaving a large hole. In the past, this was absolutely impossible.
Only this time, the potential of the warhead was almost gone, so after passing the target, it flew another dozen meters before falling down.
"Qin Zhenhua, you have solved a big problem for our army!" Bi Liansheng exclaimed: "If we had it back then, why would we be helpless in front of the T-62 tank."
The thickest part of the T-62 tank's front turret is 220 mm. At that time, various anti-tank weapons were equipped, but there was nothing that could be done about it.
Now, I finally have something good on hand!
Although it seems that it is not ready yet, this kind of warhead was originally designed for the 69 tank. The tank gun of the 69 tank has a higher chamber pressure and a faster exit speed, so the penetration depth will definitely be greater. It can definitely be used.
Arrived!
"This design is completely based on my father's design." When Qin Zhenhua said this, his voice was not high, but his heart was trembling fiercely.
Father, there is absolutely no problem with your design! Moreover, this is not the limit. When used on the 100mm slide of the 69 tank, the armor-piercing capability can reach 250mm!
Moreover, this only uses a steel core. If you apply to your superiors and get a denser tungsten alloy, the armor-piercing ability can be improved to 300 mm, which is completely no problem!
Father, you are the best tank designer!
Qin Zhenhua closed his eyes, and his father's figure appeared in his mind. Because his father was usually busy with work, Qin Zhenhua couldn't recall his smiling face now. All he recalled was his back.
It's not his design problem. Then, it's probably due to the processing. Especially for this kind of complicated bullet holder, the processing requires high precision. Is it because the processing accuracy is not enough, so it eventually leads to the chamber explosion?
As long as we can find the cannonballs that were processed at that time, we can solve the mystery!
Luo Ronggen patted Qin Zhenhua's shoulder, as if to comfort him. At this time, Luo Ronggen's eyes were also wet. How great would it be if Lao Qin was still here?
At this moment, dust was flying in the distance, and a 212 Jeep was driving quickly over the shooting range.
