"What, can't you stuff it in?" Qin Zhenhua was stunned: "How is that possible?"
The longer the core of the armor-piercing projectile, the stronger the armor-piercing capacity. Therefore, the armor-piercing projectiles produced by the Eastern powers are longer than those of the Russians. However, the warhead is stuffed in front and occupies the space inside the gun barrel. How come it can't be stuffed in.
Woolen cloth?
"First of all, the bullet holder is incompatible. We must improve the bullet holder to load the first phase of the bullet. As for the second phase of the bullet, the automatic loading opportunity will jamm the bullet." Berg said.
After hearing this explanation, Qin Zhenhua suddenly realized.
When Lao Ba discovered that the Russian tank guns were not powerful enough, he naturally thought of using the shells of the tank guns of the Eastern Powers to respond to the emergency. After all, the tank guns of the Eastern Powers are advanced in technology and have a lot of armor-piercing power.
Over the years, the Eastern powers have been working tirelessly on tank guns. After all, tanks, the king of land warfare, firepower is the first. The first goal pursued by the Eastern power is firepower. Under this pursuit, firepower is naturally considered first.
.
This not only requires high-pressure tank guns, but also advanced shells. The same tank gun, the same launching medicine, different warheads, and the depth of armor piercing will also be very different. The Eastern powers have conquered powder metallurgy manufacturing
The difficulty of tungsten alloy piercing rods is that the core of the armor-piercing projectiles produced is of high quality, so the power of the armor-piercing projectiles is also quite amazing.
For an armor-piercing bomb, the aspect ratio is an important indicator of it. The larger the aspect ratio, that is, the thinner and longer the armor-piercing bomb, the greater the depth of the armor-piercing bomb.
Due to the quality of the metal, the elastic rod cannot be made particularly fine, otherwise it will be easy to break. Therefore, it must be solved from another angle, that is, while lengthening, it must also be slightly thickened. In this way, the armor-piercing bullet
The poles are getting longer and longer.
Take the Soviet armor-piercing bombs as an example. The original 3BM32 armor-piercing bomb had a length of 380 mm. Since it was a depleted uranium armor-piercing bomb, it is likely that the tank equipment of Pakistan would not be given to Pakistan. The most advanced in the Soviet era that Pakistan could obtain.
The armor-piercing bomb should be the 3BM42 armor-piercing bomb. This armor-piercing bomb is a typical two-part bullet in the Soviet Union. It uses two-section poles covered with steel sleeves. One section is 270 mm long and the other section is 150 mm long and the total length is 420 mm.
This armor-piercing bomb is similar in size to the first-stage armor-piercing bomb exported to Pakistan by major Eastern countries. The penetration rod of the first-stage armor-piercing bomb is 430 mm long, which is different from the old Russian steel sleeve. It is an integral tungsten alloy bullet core
, and in terms of armor-piercing data, the two are similar.
Remember the URL
According to the Russians, the data of the 2,000-meter penetration depth of 3BM42 is 230 mm/60 degrees, which is equivalent to the equivalent vertical penetration depth of 460 mm, while the data of the Eastern Power is 220 mm/61.5 degrees, which is almost the same as
This data.
Although it looks the same, Lao Ba knew in his mind when he actually used it, and it was more assured to use the armor-piercing bombs from the Eastern powers. The Russian armor-piercing bombs were too heavy to hit so many.
Of course, this cannot be blamed on the Russians having a lot of moisture. How many millimeters of penetration is related to the armor material. The Russians used the targets with poor materials. The Eastern powers used high materials according to Western standards, so
Even if the data on paper is the same, the depth of the Eastern powers is about ten percent higher than that of the Russians.
In addition to the first phase of the bomb, the Eastern power also exported a small number of second phase of the bomb to Lao Ba. The length of the armor-piercing bullet has been increased to about 550 mm. By increasing the aspect-diameter ratio, its armor-piercing depth has been achieved.
The level of about 600 mm is simply a terrifying existence in Lao Ba's eyes.
Therefore, Lao Ba looked down on the Russians' armor-piercing shells at all. Although he purchased their tank guns, he did not intend to purchase a large number of shells.
Of course, the Russians also knew that their tank guns were not fire enough, so they also had a killer weapon, which was gun-fired missiles. However, that thing was too expensive, so Lao Ba didn't plan to equip the tanks at all.
The main force of the exchange of fire was still their ordinary armor-piercing bombs.
Qin Zhenhua already knew these things. The first phase of the bullet was suitable for the length, but the bullet holder was incompatible. The old Russian bullet holder was an ordinary single-ring type bullet holder. The armor-piercing bullet produced by the Eastern powers used complex saddle-shaped bullet holder.
, the second phase of the missile, the warheads of the Eastern powers are too long, so if they are placed in the Russian automatic loading machine, it will exceed the limit of the automatic loading machine.
Then why does neither the 85 tank nor the Khalid tank have this problem?
Of course, it is because the principles of the two types of loaders are different. The automatic loaders of the Eastern Powers are similar to those of the T-72 tank. The launching medicine and warhead are placed horizontally. They are lifted up directly and just push the bomb twice.
, To be extreme, it depends entirely on the diameter of the turret race. Some people have calculated from the theory that it can accommodate up to 800 mm of poles. Of course, this is just the limit. However, if you want to use a 730 mm long poles, it is still
No problem.
In order to speed up the rate of fire, the automatic loader of T-80 is loaded in one go. Therefore, its warhead and the launching medicine behind it are ninety degrees, and are placed in an L-shaped shape. When lifted up, it needs to be turned over once. In this way,
The total length of the warhead is greatly limited.
Lao Ba cannot solve these problems, so he wants to ask the Eastern power to solve these problems.
"Our second phase bomb is difficult to stuff in, and it is difficult to solve this problem. However, since the first phase bomb is just a bullet holder and is incompatible, we can improve the bullet holder so that it can be used on the T-80 tank.
Our first phase was bombed." Qin Zhenhua said: "As for the issue of using our second phase bomb, we need a T-80 tank as a prototype. After careful research, we can determine how to improve it."
Qin Zhenhua has promised that he can help them solve the problem, but it is hard for a good cook to cook without rice. He must have samples under his command, so that it is convenient for research. Since Lao Ba wants to ask his side to improve the shells for them, he must bring the tanks over and let his side study them?
Hearing Qin Zhenhua's words, Berg just pondered for a moment and nodded: "There is no problem with this, but we need to keep it highly confidential. If Ermao knows about it, there may be other troubles."
Berg's answer surprised Qin Zhenhua. He thought they would refuse, but he agreed so happily?
"We have another request." At this moment, Baker made another request: "At present, we already own hundreds of 85 tanks, and will soon own Khalid tanks. We will also own a batch of T-80UD tanks.
,These tanks will use the same ammunition, so we hope that you can export the production technology to give us a phase of ammunition, so that we can produce this shell ourselves and solve the problem of ammunition replenishment."
This is what Berger hopes to get most during this visit.
