When ordinary bullet cores could no longer meet the needs, the Soviets began to choose depleted uranium as the piercing rod of armor-piercing bombs. The 3BM32 bullet core, which was put into service in 1985, was made of depleted uranium, nickel and zinc alloys. The total length of the bullet core is
480mm is the shortest armor-piercing bomb in the Soviet Union so far. The length of the pole inside is only 380mm. The Soviets seemed to realize that there was a big disadvantage to doing this, so they deliberately lowered the diameter of the pole from the original 36mm.
At 30 mm, the length-to-diameter ratio 13 to one was finally achieved.
Although its data are not high, as the first Soviet Union's tail-resisting armor-piercing projectile that uses an integral core, this short-stick armor-piercing projectile poses a great threat to NATO tanks produced before the 1990s.
It is initially estimated that this armor-piercing bomb can reach 500 mm at a depth of 2,000 meters. This is the first armor-piercing bomb in the Soviet Union with a depth of more than 500 mm!
Seeing these data, Qin Zhenhua felt a little nervous, and his penetration depth was more than 500 mm, which means that all the tanks in the current service in China could not stop the shooting of this armor-piercing shell. This shell was in 1985.
It has been in service, and now five years have passed. It is conceivable that the Soviet army must have been equipped with a large number of armor-piercing bombs. Even if it is mainly equipped in European troops, it may be transported to the Far East at any time.
Come.
Seeing the possible numbers above, Qin Zhenhua also knew in his heart that it seemed that the West had obtained this kind of armor-piercing bomb, but it did not obtain a supporting T-80 tank, or was launched from the T-72 tank, and the launching medicine was insufficient, so it was only
Can measure a rough number.
Although the T-72 and T-80 both use tank guns called 2A46, the chamber pressure they bear must be different, especially the export version, which is definitely reduced.
Qin Zhenhua looked through it carefully, and then saw the information behind it.
Since depleted uranium is radioactive and will be scrapped after a long time, the Soviet Union began to study a low-end ammunition that was slightly inferior to 3BM32, code-named 3BM42, which was put into use in 1986.
In the low-end version, sure enough, this model of larger armor-piercing bullet will not be as deep as the former.
The latter uses tungsten alloy material, and the Soviets finally mastered the liquid sintering and forging technology. The length of this 3BM42 tungsten-based alloy armor-piercing body reached 420 mm and the diameter was reduced to 18 mm. If calculated based on this data,
If so, its aspect ratio reaches 28, which is surprisingly high, however, like other Soviet armor-piercing bombs, it uses a two-section core design under the protection of steel sleeves. The steel is equipped with traditional height.
Hard alloy steel, the front half of the elastic core is a rigidly connected high-hard alloy steel, and the second half is a complete tungsten alloy elastic core. This design greatly reduces its armor-piercing ability, which shows that the Soviets did not really
To solve the fragility problem of tungsten alloy, I am afraid that the overall way of piercing the rod will cause the core to break during the armor piercing process, or, in order to save costs, because the first half is not a pure tungsten alloy.
Therefore, the Soviet Union's tail wing stable shell-out armor-piercing bullets was still very particular in calculating the aspect ratio. If calculated based on the steel sleeve, the aspect ratio data would be greatly reduced. The Soviets' designs were always so strange.
The Western pole is a pole that never involves two bullets. The steel cover in the middle is simply a superfluous amount.
These analysis is very detailed, which is enough to show that the analysts must have obtained this kind of armor-piercing shell. For the Soviet Union, the number of tanks was fixed, and it was not easy to tinker with, but it should be easy to sell a few shells for some money.
, without even a senior officer, an ordinary tank leader can sell the shells inside his tank, perhaps just to exchange for a few bottles of vodka.
Thinking of this, Qin Zhenhua felt a strange feeling in his heart. A once huge bear that made the world tremble has now become like this, which is sad.
Continue to look downward. At a distance of two thousand meters, the estimated depth of penetration is about 450 mm. The depth of penetration at close range may reach 500 mm. If it is reached, this will be the first model in Soviet history.
Tungsten alloy armor-piercing bomb with a penetration depth of up to 500 mm.
After reading these information, Qin Zhenhua closed the folder, then closed his eyes, and was speechless for a long time.
These two armor-piercing bombs were both fixed-type equipment for the Soviet Union in the mid-1980s. So, a few years have passed. Will the Soviet armor-piercing bombs be further improved? In other words, will the Soviet armor-piercing bombs be further improved?
Have the potential to reach 600 mm?
If this is the case, then there will be problems with our third generation tanks.
When the design indicators were proposed, the protective power of the front of the third-generation tank was designed according to 600 mm. According to the current progress, this tank will take at least five years or even ten years to equip the troops. This third-generation tank will be available for at least five years.
When the tanks were equipped with troops, Soviet tank soldiers had already begun to use armor-piercing bullets with a depth of 600 mm.
In that case, your tank will be in a state of being behind and beaten as soon as it is successfully established.
If you want to be more secure, then the frontal protection of the third-generation tank must reach 700 mm, so that you can gain the lead. However, if this is the case, the design of the third-generation tank will really have to be pushed back and started over.
.
There were twists and turns on the gearbox, and the protection strength was twists and turns. If this continues, the third generation of tanks will continue to experience ups and downs. Will there be a day of success?
Qin Zhenhua has already begun to worry about Mr. Zhu.
Looking at Qin Zhenhua's appearance, Nie Qianqian on the side did not speak.
Although spring has arrived, the grassland is still cold, and white snow is covered with outside. In the corners near the building, due to the release of heating in the room, some places have begun to reveal emerald green colors. That is
Life is growing tenaciously.
The first machine factory, as well as the entire tank industry and military industry of the Eastern powers, are growing tenaciously.
In the workshop, the workers were still working non-stop. In the secret factory, next to the T-80 tank, there was a group of people studying there. The engine compartment at the tail of the tank was also opened, facing the
This unique diesel engine is also very interested in people.
For a long time, the military industry of the Eastern powers has been imitating the Soviets. Now, the West has closed its doors, and the Soviet gate seems to be slowly opening. How should we go on this road of the Eastern powers?
