The slender core flies forward, with its tail wing spreading to maintain the balance of the bullet body, just like an arrow radiated from ancient times.
In the past, when people just learned to use bows and arrows, they had discovered that slender arrows would become more stable if they were touched by a few feathers at the tail. From then on, they had been used for thousands of years.
Later, in the era of guns and cannons, the bullets were spherical at first, and after flying out, they floated around, which was very unstable, and troubled many gun designers. As a result, an officer solved it and applied the principle of gyroscopes.
, let the bullet rotate and keep it stable!
From then on, guns and cannons began to exert great power. There is rifle inside the gun. When the bullet flew out, it rotated along the rifle to stabilize its bullet body. Even if it was two thousand meters away, it could have a relatively high level.
At the same time, spherical projectiles gradually evolved into the shape of a pointed cone, which is also a research result of aerodynamics.
From then on, almost any firearm or artillery was rifled, even if it was the naval guns of huge battleships.
However, after World War II, the development of tank guns, smoothbore guns began to gradually become mainstream again. After the rifle was cancelled, the shells could not be affected by resistance, so they flew faster, and the initial speed at the muzzle was
It will be higher, which is an important indicator for armor-piercing bombs.
In the process of breaking through the armor, the slender pole has become the mainstream again. This pole must not rotate at high speed. Therefore, the method of stabilizing the tail wing can be described as a development of weapons.
A special situation.
The slender elastic rod leaned against the four-piece tail wing at the tail to maintain the stability of flight. The distance of 1,500 meters was not enough for a second. Then, the warhead hit the first piece of 100.
On mm thick homogeneous armored steel!
The pointed warhead hit the armored steel hard. The moment the warhead and armored steel collided, a head-on contest began. The huge kinetic energy was converted into internal energy, and the temperature rose rapidly in a short period of time! Poor uranium-poor uranium-poor uranium-poor uranium-poor uranium-poor uranium-poor uranium-poor uranium-poor uranium-poor uranium-poor uranium-poor uranium-poor uranium-poor uranium-poor uranium-poor uranium-poor uranium-poor uranium-poor uranium-poor uranium-poor uranium-poor uranium-poor uranium-poor uranium-poor uranium-poor uranium-poor uranium-poor uranium-poor ur
The alloy warhead was also colliding, and the foam flew everywhere, and then the dust suddenly started to burn!
The temperature of the collision has long exceeded thousands of degrees, and even the armored steel is melting! And the dust is even burning.
If you are an amateur, when you look at the shells, you will always sigh at the huge power of the shells, and then leave a huge crater that makes people sigh, but it is the result of a high-explosive grenade. For ordinary armor-piercing bombs, it
The armor-piercing process does not seem to be a thrilling process, it is like a fork that has been put into the soil, and at most some mud is splashed. As for that magnificent scene, it is not the power of the armor-piercing bomb itself, but
Ammunition inside the tank exploded.
What about now?
Now a strange scene appeared. During the armor-piercing bomb, fire actually emerged!
The human eye is not a high-speed camera, and the whole process cannot be seen. At this time, in everyone's field of vision, I only saw the first steel plate, which trembled suddenly, and then a big fireball emerged from the middle of the steel plate.
It instantly occupied the entire steel plate, as if it was a magician's mouth, and it looked like it was full of a strange smell!
The core of the elastic had easily passed through the first steel plate, and then, the same situation occurred on the second steel plate. The steel plate also burned into a fire during the violent collision!
The third and fourth pieces, in fact, the armor-piercing bombs are quite fast during the armor-piercing process. Although these four flames rise in sequence, in fact, in people's eyes, it is only a moment.
What happened was like setting off firecrackers. After igniting the twist, the firecrackers started to crackle. Now, these steel plates were like firecrackers worn together, all of which were ignited!
Everyone's eyes widened. No wonder they had to place these armored steel plates like this. It turned out to be a show for everyone. This scene was really spectacular!
Without blinking, everyone held their breath and watched the armor-piercing process of the armor-piercing bullets.
The fifth steel plate has been burning, and splashing sparks appear from the back of the steel plate, indicating that the fifth steel plate has been penetrated.
This has reached the depth of 500 mm. In fact, this method is more difficult than directly breaking through the thickness of 500 mm, because there is a gap in the middle, even if the air fills the gap, it will
It can be said that it is gap armor, and its bulletproof ability will be better.
The warhead will undergo a series of sudden impact and sudden relaxation, which is definitely more complicated than passing through it in one breath.
The sixth steel plate has also started to burn, but its combustion looks much smaller. This is because by the last part, the kinetic energy of the core of the armor-piercing bullet was already very small, so the impact energy was insufficient
, the effect is a little worse.
"How could it catch a fire?"
Now, seeing that the process of armor-piercing has ended, after piercing through a thickness of 500 mm, I continued to penetrate the sixth steel plate. Everyone was already very satisfied with the performance of this armor-piercing bomb, and the scene was like this.
It's spectacular, this scene lingers in everyone's minds, and I don't know how long it will take to recall it.
I was so impressed.
Some people have also raised this question.
I have never seen burning before. Maybe I have seen the steel plate melt under impact and the contact area turns into a molten shape, but it is absolutely impossible to see a ball of fire burning on the steel plate.
What's going on?
"That's the No. 4 special alloy dust burning." Qin Zhenhua said: "Now, please send our base fire truck to dispatch and spray water in that space. By the way, let's take a shower of our car.
”
At this moment, although Qin Zhenhua said it casually, this operation is necessary.
Everyone realized that this was a protective method used by the equipment after passing through the problematic area, which only appeared under the conditions of nuclear, biochemical warfare.
"This is Pandora's box." Old He sighed.
When Qin Zhenhua talked about these operations, Mr. He had already fully understood it. It is beneficial to use this material as the rod of the armor-piercing bullet, because it can significantly increase the depth of the armor-piercing, which is what makes people like.
, but at the same time, it also has its disadvantages, because during the process of armor piercing, there is radioactive dust, and after combustion, these dusts will even float further away. After all, depleted uranium is also uranium!
