Chapter 457: Just 1 piece of paper

With the sound of the cannon, a fiery flame emerged from the trumpet of the second half, which instantly surrounded the back. This scene was definitely more spectacular than launching a rocket launcher.
These flames spread back to a distance of fifty meters, and one hundred meters away, you can feel the heat!
The smoke filled.
The operation of this gun is quite dangerous, but its power is also quite against the sky!
This is a 75mm gun after all! The warhead flying at a speed of 365 meters per second flew towards the French tank that had approached a distance of one kilometer on the opposite side!
At this distance, it takes about three seconds to fly.
When the flame on the opposite side was spotted, Bailey shouted loudly: "Turn left at full speed!"
The opponent fired a cannonball, no matter what the cannonball, in short, it will definitely be a threat to oneself, how to deal with this threat?
You can brake or steer immediately, depending on where the threat comes from. If it is from the side, braking is the best method, but now it is almost frontal and direct shot, then the brakes will not work.
Can only turn!
However, Bailey failed.
If the speed is fast enough, then his steering can still avoid, but now, even the S-35 tank, the speed is too low!
Hearing his command, the tank pulled the brake on one side, the track on the left locked, and the track on the right was still rotating. In this way, the tank brushed the ground and turned to the left.
If he was given two more seconds, he would be out of danger, but now, just after the steering is completed, the car body is still in the outline of the projection just now, and the shell is flying over!
If the muzzle velocity of the shell is high enough, for example, more than 700 meters per second, then at this time, the opponent can be killed directly with kinetic energy. This is the principle of armor-piercing shells.
But now, recoilless guns are low-pressure guns, the muzzle velocity is too small, if direct impact is not enough, so this flying shell is not armor-piercing shells, not grenades, but armor-piercing shells!
In this era, the main force of anti-armor is still ordinary armor-piercing ammunition, but all kinds of new anti-armor ammunition are under rapid development.
Among them, the principle of armor-piercing bombs can be traced back to 1888, when the energy-gathering effect of explosive columns with dimples was discovered.
However, it was not used effectively at that time. Until World War II, during the Spanish Civil War in 1936, the German Intervention Army first used armor-piercing bombs.
However, it was still not promoted. Until the early stage of World War II, it was discovered that when the explosive charge was lined with a thin metal cover, the armor-breaking power generated by the charge was greatly enhanced, which led to the widespread application of the energy-generating effect. Shine.
A cone-shaped metal medicine cover plays the role of converging the metal jets. It can be said that an idea changes the world.
The advantage of being a traverser must of course be manifested. Therefore, the further application of the energy gathering effect has long been overcome by German military experts.
Just like a mirror converging light, a copper cone-shaped medicine cover is used to converge the metal jet!
At this time, this 75mm armor-piercing projectile accurately hit the middle of the s-35.
After the impact, it was as if a piece of surface was smashed flat, and the front end was instantly subjected to huge pressure. This pressure triggered the mechanical fuze, and the explosive in the warhead exploded violently.
Behind the copper cone, the shock wave generated by the explosion hits the metal lining at a speed of 8,000 meters per second, and is concentrated on the cone.
Under this pressure, the entire metal lining is compressed toward the bottom of the cone, and the pressure is concentrated on the center line of the cone. The compressed metal linings are stacked together and then pushed out from the center of the cone bottom.
Under the huge pressure, these metals are sprayed out in a straight line at a powerful speed of 8000 meters per second. This is the principle of armor-piercing bullets, using metal jets!
This powerful metal jet hit the s-35's armor, and its powerful kinetic energy forced the steel structure of the steel armor to flow in liquid around it, giving way to a tunnel.
If you can cut one side, you can see the domineering metal jet at this time.
At the same time, the head of the jet continues to spread to the surroundings, and the jet continues to be consumed. Moreover, the energy of the subsequent metal jet is insufficient. After all, the explosion is only a momentary event.
Now, entering the final stage, there are only two results. If the jet cannot penetrate the armor when it is completely spent, it cannot penetrate the opponent. Otherwise, the armor is destroyed.
What is the result now? Of course the tank was destroyed!
According to the theory of later generations, the penetration data of the armor-piercing projectile is at least five times the diameter, that is to say, a 75mm projectile can penetrate more than 300mm of armor!
Of course, it is definitely not so high in fact, but it is still effortless to penetrate the s-35. -35 belongs to the 20-ton tank, the armor protection is not weak, the front armor thickness of the turret is 55 mm, the body armor thickness is 40 mm, and the weakest rear part is also 20 mm.
According to historical data, the tank gun at this time is only 37 mm to 50 mm, and it can withstand it.
But ~EbookFREE.me~ in front of the current lg40 recoilless gun, it is just a piece of paper!
The metal jet, with almost no obstruction, penetrated the 40mm armor effortlessly. When the first heat flow entered the car body, in an instant, the entire car body burned into a big fire!
At this time, the temperature of the metal jet was as high as several hundred degrees, and the speed was also several kilometers per second. It was a fire wherever it went.
A pinch of trickle sputtered onto the 75mm ammunition, and in an instant, a violent explosion was produced.
"Boom!" Amidst the loud sound, the ammunition exploded.
The small turret, at this time, was directly lifted by this huge air current. As for the people inside, of course it is impossible to live. This is the fate of the tank soldiers.
When the tank is hit, the tank is their metal grave.
The explosion of this tank stunned the other tankers in an instant.
what happened?
If the opponent is a tank, that's fine, they can accept it, but now, what does the opponent have? Just a few broken motorcycles, they actually destroyed your own tank?
This is simply terrible! Especially the other tank close to this tank, after witnessing the martyrdom inside, was frightened.
"Quickly, reverse gear and retreat!" the captain shouted loudly.
If they continue to charge with determination and courage at this time, they should be able to push the past. After all, the opponent has only one motorcycle with this big killer, and the other motorcycles are machine guns.
However, they were frightened.
When the whole country was chanting for peace, the soldiers also lost their blood. These front-line soldiers almost never went through that cruel battle, and they did not have the courage to fight to death.
