The 231st chapter is not afraid of making things difficult
It seems that when Qin Zhenhua went to England last time, he kept playing tricks to deceive them. Therefore, when he came here this time, they also made trouble again and again.
At the beginning, they said they wanted to shoot from a long distance, which was a clear-cut attitude of taking advantage, and they just wanted to see the good show here. They guessed that the shooting here would not be far, inaccurate, and weak. However, moving here
After the shells came out, they immediately realized that their guess was wrong.
According to their experience and analysis, their artillery shell could really fly over a distance of 2,500 meters and then penetrate the 350 mm thick target. After all, this artillery shell looked very high-end.
The material of the bullet core is very special, the length-to-diameter ratio is incredibly high, and the bullet holder is also very delicate and matches perfectly, so the previous ideas are completely overthrown.
However, if you just admit defeat, of course it won't work.
So, the experienced Robert came up with this new trick.
Changing the target from a vertical target to an inclined target, although the thickness is the same, is more than a little more difficult! Among them, the most important test is whether the bullet core will break.
When it hits the target vertically, the bullet core only experiences resistance perpendicular to the bullet core. Under the action of this resistance, it will slow down and begin to penetrate into the target, engaging in a head-to-head contest.
What if it's tilted?
When the bullet core comes into contact with the target, it will receive an oblique force. If the angle of the bullet is not appropriate, it will even directly slip and be bounced off the target. This is an important problem that once plagued armor-piercing bullets.
The capped armor-piercing bullets used later solved the problem through the positive effect.
But today's slender armor-piercing bullets do not have this positive turning effect. If they hit it at any angle, they will drill in at any angle. The front has already received resistance, and the rear is still flying. In this way, the rear core will push the front core forward.
A lateral force is generated, and if the material of the bullet core is not hard enough, it will easily break.
This is because everyone knows that increasing the aspect ratio of the bullet core can effectively increase the penetration depth. However, in fact, it is difficult to increase this indicator quickly and efficiently, because the more slender the bullet core, the easier it is to break.
They may be able to achieve a penetration depth of 350 mm, but their bullet cores are likely to break. At that time, they can make fun of the impracticality of their shells. This is Robert's idea.
This ability to adapt to changes made Qin Zhenhua sigh. Sure enough, Jiang is still very good. Once he is prepared, he will come prepared and come up with tricks one after another.
We just said that we should shoot from a longer distance, and we didn't say what target we would shoot at. Now the other party proposes to use an oblique target instead, which makes sense. If our side disagrees, then the other side will continue to despise us.
In fact, if you think about it from another perspective, you will probably make this request to save face. Unfortunately, they still take it for granted. The purpose of developing new armor-piercing projectiles is for actual combat. How can they only hit fixed targets?
In countless test firings, they all hit oblique targets. Now, if they want to use this to embarrass themselves, then let them be convinced of their defeat.
"Okay, let's go up to the inclined target." Qin Zhenhua said: "Would you like to go over and check first to see if the tilt angle of the target meets the requirements?"
Come up with the questions, no matter how you come up with the questions, we are not afraid! The attitude shown by Qin Zhenhua immediately made Robert's heart skip a beat. Could it be that the other party is confident?
Impossible, impossible. In this case, their armor-piercing bullets are simply more advanced than our own!
Comforting himself in this way, Robert showed a calm expression on his face: "No need."
There is no way to fake the angle at which the target is placed, because when you pass it diagonally, you can cut the target and measure the angle yourself.
"The shooting begins!"
Finally, after some delay, the gun test began again. In the turret, the best gunner in the armored force was responsible for the test. He had already quickly bound various weapons according to the firing list prepared in advance.
The shooting data, the distance of 2,500 meters, must not be embarrassing!
In the turret, the gunner made careful and repeated adjustments, took a deep breath, and then stepped on the trigger.
"Boom!" Amidst the huge roar, a flame burst out from the muzzle. The bullet core flew out from the flame at the muzzle at a speed of more than 1,400 meters per second, bounced off the bullet holder, and flew towards the target.
past!
The inside of the turret was filled with smoke, and the top hatch of the turret was open. Therefore, rising from this hatch gave a rather different aura.
100 slip is powerful enough, but if given the choice, Qin Zhenhua would still choose this L7 tank gun without hesitation, because it is lighter and more efficient. We have already exploited the potential of 100 slip to the extreme.
It has achieved the current armor-piercing power, and if the L7 tank gun taps into its potential, it will be appropriate to increase the penetration by another 50%!
The opponent raised two problems one after another, thinking that they could stump us. In fact, this was just a fantasy. To say that our disadvantage was not the armor-piercing ability, but the aiming! Now let's talk about target shooting at 2,500 meters.
As long as the core of the bullet does not float, it can hit the target with a certain shooting table. However, if it is a moving target, it will definitely not hit the target.
However, the comparison now is about penetration, not aiming. Compared with penetration 2,500 meters away, it makes sense, but comparing aiming? That would be too much.
The introduction of the L7 tank gun is a major systematic project, and the supporting fire control system must also be introduced, which is actually more important.
Just as I was thinking about this, the target reporter's voice sounded: "Successfully hit and penetrated the target!"
What?
His expression was originally gloomy due to lack of self-confidence. After hearing the news, Robert finally lost his composure: "No, this is not scientific!"
When a person shouts loudly, it can only mean that he can no longer control his emotions. A person who cannot control his emotions has failed.
Now Robert's eyes were full of disappointment and his arrogance was completely defeated at this moment.
"We're going to see it, immediately, immediately!" Joyce shouted from the side.
What if it is a fake? How about preparing a target with holes in it in advance to fool people? Now go over and feel the hole in the target to see if it is hot or not, and you will know whether it is real or fake.
"This is very scientific." Qin Zhenhua said with a smile: "Let's take you over and have a look!"
He knew that the other party would have questions, and at the same time, for convenience, Pianzhuzi had already prepared them. Now, Qin Zhenhua strode over, kicked the fire, and waved to them.
