Seeing that Kogin's expression was constantly changing, he seemed to have some ideas. Knowing that it was time for him to add fuel to the fire, Malashenko pursued the victory. When he felt that Kogin understood more than half of the truth, he spoke again.
"Just like the stone-throwing story I just told, if we use the same propellant to convert into combustion chemical energy, we can launch smaller-diameter projectiles out of the gun barrel, and at the same time, somehow reduce the wind resistance of the projectiles.
The cross-section is further reduced to enhance its ability to store energy during ballistic flight."
"I don't think I need to say more about what this new armor-piercing projectile design will mean, Comrade Kogin."
Kogin is not a stupid person. As the number one world-class heavy tank designer with the father of Red Army heavy tanks on his head, Kogin can lead his team to design a world-famous first-class heavy tank. This is because he has real skills.
of.
Under the premise that Malashenko has already said this, it is almost impossible for Kotin to still not understand what Comrade Ma is trying to express.
"I understand, you are referring to...well, sub-caliber armor-piercing projectiles! Yes, this should be the most appropriate name."
"We use the same amount of propellant to launch armor-piercing projectiles with a diameter smaller than the caliber of the main gun from the barrel. Because the projectile itself has a smaller diameter and wind resistance surface, and is lighter in weight, under the same amount of propellant
With a higher muzzle velocity, more energy will be stored when it finally reaches the target, and the kinetic energy lost on the ballistic flight path will be much lower, which will eventually lead to the ability to penetrate thicker armor, thus greatly increasing the projectile's effectiveness.
Armor penetration depth, am I right?"
Malashenko originally thought that he would need to go through many rounds of narration and repeated explanations before Kogin could understand what he meant and understand it thoroughly.
Now it seems that Malashenko has underestimated Comrade Kotin's understanding and ability.
Think about it, how could a world-class top heavy tank master, a legendary figure who can design the pinnacle of the world's most powerful heavy tanks of his generation, be unable to understand such a simple truth, under the premise that it has been explained so clearly?
.
As far as Kotin is concerned, Malashenko now feels that this is almost like an open-book exam, basically putting the answers in front of Kotin and letting Kotin do the "reading comprehension" on his own.
In response to Kogin's perfect answer, Malashenko simply nodded and said no more words.
After getting a positive answer from Malashenko, Kotin, who no longer cared about picking up the food on the plate, completely entered a state of selflessness.
Without saying a word, he took out the notepad and pen he carried with him. Such important details and flashes of inspiration must be recorded immediately without any mistakes. Ke Jing cannot guarantee that he will be as understanding as he is now.
It is clear and thorough. After all, this is a new conceptual field that no one has ever set foot in. The slightest mistake may lead to missing the future.
Malashenko did not interfere with Kogin's behavior of ignoring him. He just reached out and grabbed another plate of lamb chops that had been prepared. He took a big bite of the mutton chops on the side. Kogin had long known that Malashenko had an absolute appetite.
It's just one plate that won't fill you up, just make enough preparations in advance, it's that simple.
About two minutes passed, and when Kogin raised his head again with an expression that seemed relieved but worried, Malashenko, who noticed the change in Kogin's expression, knew that Kogin was finally going to say something.
.
"I never thought this was possible! Theoretically there is no problem, the only thing left is the difficulty of realizing this concept."
"We have to consider the stability of sub-caliber projectiles during firing in the barrel. The full-caliber rifling cannot limit the sub-caliber projectiles and cannot stabilize the spin of the projectiles. This will directly affect the shooting accuracy. Use the traditional design
It is impossible. Sufficient innovation must be made in design to solve this problem, which will be a relatively complex task."
As soon as Kogin's words came out of his mouth, Malashenko knew that Kogin was far from fully understanding what he wanted to express. In fact, in the final analysis, he was still a little behind.
Kotin only fully understands why sub-caliber projectiles have higher armor penetration depth, but he has not yet understood the design and application principles of sub-caliber projectiles. At this time, Malashenko is needed to add fuel to Kotin's fire.
"This problem is not difficult to solve, Comrade Kogin."
"We can make such a design. This new type of armor-piercing projectile is still in full-caliber state when it is in the barrel, and is covered by a hollow steel projectile shell. A true armor-piercing projectile is in a hollow steel projectile.
The shell of the projectile is rigidly fixed, or it is in a state of being clamped and temporarily fixed, at least when it is not launched, it is absolutely stable and rigidly fixed.”
"But this hollow steel projectile shell is temporary. It cannot fly forward with the projectile itself in the air. If this is the case, it will still be a full-caliber armor-piercing projectile, which has lost our original conceptual meaning."
"What we have to do is to make this hollow steel projectile shell, in the process of being pushed out of the barrel by the propellant, use the rotation of the spiral rifling to give it a real armor-piercing projectile wrapped in a rigid connection inside.
, a spin stability to ensure shooting accuracy.”
"After the cannon is ejected from the chamber, this temporary hollow steel projectile shell will automatically crack and fall like withered petals. This design is not difficult and can be done during the assembly of the cannonball. The hollow steel projectile shell
The projectile shell itself is a separate structure, and it is only temporarily fixed and held together by the propellant barrel."
"To put it simply, this is a fake full-caliber projectile. The purpose is to allow the real sub-caliber projectile inside to obtain the spiral stability given by the rifling. This is the simplest way I can think of to describe it. If you can't explain it clearly yet
, I think we can get some paper and draw pictures, that would be better."
Malashenko could only try his best. He was not sure whether his explanation could be understood clearly by Kogin, because even when he said it, he felt that this was actually a quite complicated concept. Can anyone let him understand it for the first time?
It’s really hard to say that you can understand it thoroughly at once, let alone this is the first time for someone to come into contact with this new concept.
But what Malashenko didn't expect was that Kogin's next expression didn't mean anything like "I don't understand." He just quietly spoke again and asked Malashenko.
"I think I know what to do with this new type of armor-piercing bullet. Have you thought of a name for it?"
Malashenko was startled for a moment, then quickly faced Kogin with a faint smile.
"Of course, its name is armor-piercing discarding sabot."
