Different shells have different sizes. The largest shell made by humans should be the 800mm cannon shell from Germany during World War II. This thing is just a warhead, which is already the height of two adults.
Of course, cannons of that level have entered the History Museum. No matter how powerful the shells are, they are not as useful as missiles. Cannons of that level will definitely cause a collapse in operation.
Now, the 140mm shell is quite large in size. Only by loading the tailgate can this large shell meet the needs of automatic loading, and the shells can be stuffed directly from outside.
It is inconvenient for one person to hold it. Two people have to carry it to load this shell into the barrel. Of course, this is also because it is a complete shell. If it is a separate shell, then a person can
Moved.
Looking at this shell, Qin Zhenhua was also a little amazed.
In fact, the current development of tank guns has two directions.
One of the directions is of course to continue to increase the caliber of the tank gun. It is also quite common to enhance the performance of the tank gun by increasing the caliber, but the side effects are also very huge, and the huge volume of this whole shell.
It's one of the deadly problems.
Another direction is advanced electromagnetic cannons. After all, high technology has begun to develop, and the military's weapons and equipment have also reached an era of change. Compared with ordinary cannons fired by gunpowder, electromagnetic cannons have many advantages in nature.
For example, the initial speed of shells flying out is higher, the recoil of the cannon is smaller, there is no flame or smoke when firing, etc.
Therefore, many experts believe that if the development of tank guns continues, it will be the era of electromagnetic guns.
However, the electromagnetic gun is too fantasy after all. Until now, it has only appeared in theory. No one knows what the actual situation is. So, in this case, the future tank gun will be rashly pressed on the electromagnetic gun.
Oh, if this thing is immature and the army cannot use it, something big will happen.
The army never rashly uses new technologies. Although they have aspirations for new technologies, they must first ensure reliability.
Back then, the US Air Force pursued new technology and created a cross-age F-15 fighter jet. As a result, due to the immature engine, it was grounded on a large scale and became the queen of the hangar. This was the result of the rash pursuit of advanced technology.
Now, although the electromagnetic gun is praised by countless people, it is still difficult to apply this thing to actual combat. Therefore, the Second Machinery Factory also launched a 140mm tank gun project in this judgment.
Pre-research, once necessary, can be installed on a tank, even if it is used as a backup solution, it is beneficial.
At this time, Qin Zhenhua sighed at the huge size of the 140mm tank gun while watching the technician load the shell into the barrel and then began to aim.
After the cannon is made, a test of the cannon is required. The first thing to test is the reliability of the cannon, so the shell does not require too good materials. Although the armor-piercing shell is used, the warhead is just ordinary high-carbon steel.
If you use a tungsten alloy warhead, this shell will cost more than 100,000 yuan, which is simply impossible to consume.
Although it is just an ordinary steel core bullet, due to its high initial velocity and strong power, a target of one meter thick homogeneous steel is prepared one meter away.
"Already aimed, requesting fire." A technician shouted.
"You can open fire." Xie Huimin said.
With his shouting, the technicians around him quickly retreated, leaving only an old technician. He held a long rope in his hand and retreated several meters away, and then gradually tightened the rope.
Finally, he held up suddenly.
The rope-pull-firing is an ancient artillery fire method. When the cannon is made, it is the first to point the cannon twist. After this method is eliminated, it starts to use the rope-pull-firing method, using the rope to drive the tail of the cannon chamber.
The striker hits the bottom fire. This method has been used until now. Even if it is a 155 self-propelled howitzer, when firing, the first shot must be pulled by a rope to avoid accidents.
At this time, as the old technician pulled the rope with his hands, the 140mm tank gun was fired.
boom!
Amid the huge sound, a large fireball of more than one meter in diameter appeared from the muzzle, and black smoke rose slowly, forming a small cloud of mushrooms. The scene was extremely spectacular.
When the air waves slapped, Qin Zhenhua only felt that he was like leaves floating in the wind and rain, and was almost blown away by the air waves at the muzzle. This made him stun his tongue. Although the caliber was only 15 mm higher,
The power of this muzzle is as if it has doubled.
The eardrum was still hurting, the shell had already flew out, and the two bullet cores that shook off the bullet cores of the bullet cores that flew at high speed in the air, rubbing against the air, making a numb sound that made people's ears scream. Then the bullet cores pierced into it
In the target a thousand meters away.
The steel target suddenly turned red, and then the steel shot out and separated in all directions. At this time, the target seemed to have just melted from the steelmaking furnace. It could be seen clearly one thousand meters away.
Chu.
There is no doubt that under the impact of this huge energy, the one-meter-thick steel plate must have been penetrated.
His ears were still buzzing. Xie Huimin, who was beside Qin Zhenhua, smiled and said loudly to him: "Director Qin, how about it? Is this kind of cannon powerful enough?"
Although its caliber is only 140 mm, since it is a tank gun with high pressure, there are more drugs in the barrel than 155 mm howitzers. Now that it is fired like this, the scene is of course very spectacular.
Qin Zhenhua nodded: "Yes, it's so fierce. I'm really worried that our tanks will not bear it."
It's so strong, and the recoil is also very strong! Can it be used on a 99 tank?
"Let's go and see the effect." Xie Huimin said.
Today's test gun site is only this one, and only one cannon is fired. Next, we have to study it, sort out the data, and then fire the second shell.
Qin Zhenhua and Xie Huimin walked over. A thousand meters away, the target of the homogeneous steel was not only penetrated by a hole, but also the entire piece of armored steel had been twisted and deformed! It was brought by the huge impact force.
The consequence is that if it is a tank, it will be twisted and deformed.
This is the power brought by a large-caliber artillery. Even if it cannot penetrate the opponent's armor, the tank player has no chance of surviving under such impact and is directly shot to death.
