Chapter five hundred and eighty fifth ten thousand one shot
In fact, in recent years, relevant departments have also thought of the upgrade of the 100mm tank gun. Therefore, in 1979, the 100mm armor-piercing bomb was successfully developed, which was considered to have added a type of bomb, and then it was successfully developed.
100mm diameter tungsten armor-piercing bomb, the initial velocity of this armor-piercing bomb is 1435 meters per second, and the direct shooting distance is 1640 meters. The armor-piercing power is greatly improved compared to the previously imitated БР-412 armor-piercing bomb, which can penetrate tanks such as T-55.
Front armor of the vehicle body.
However, this 100mm tungsten-headed armor-piercing projectile is also a full-caliber armor-piercing projectile. It is prone to jump when the hit inclination angle is large, so no one knows the actual performance.
As for the sub-caliber armor-piercing bomb? No one is sure how to build the sub-caliber armor-piercing bomb of this rifled gun before introducing the 105mm rifled gun and how to create the sliding elastic belt with the most complex technology.
So, this matter was put on hold.
Until now, in order to sell the 69 tank, the first aircraft factory completed the research and development of these shells in advance. Anyway, when Qin Zhenhua made a big splash, he relied on the technology of armor-piercing bombs.
Now, Qin Zhenhua introduced the two armor-piercing shells in front: "We have fully introduced and digested and absorbed 105mm tank guns. On this basis, we have improved the armor-piercing shells of our own 100mm tank guns, almost
It’s just imitation and reduction. As for the performance, it is naturally not as good as our 105mm armor-piercing bomb, but overall, the improvement is still obvious.”
After saying that, Qin Zhenhua pointed to a shell on the left and said, "This is our first phase of the shell. This shell is 950 mm in length. The core of the shell is made of a tungsten alloy core with an aspect ratio of 15.
, During the test shot, the armor-piercing ability has reached 250 mm."
Now, the ones sold are this kind of shell. Compared with the previous penetration depth of more than 100 mm, the performance has been almost half improved. It is fully capable of breaking through the front main armor of the Chieftain tank. It is because of this armor-piercing shell.
Only then will the 69 tanks win three in one match.
Of course, this has a lot to do with the quality of the tank player. If both sides change, it will definitely be a one-sided record.
"Looking at this point, we are using the latest powder metallurgy technology to create a new armor-piercing bomb." When Qin Zhenhua said this, he sighed in his heart. This is the bullet core he got when he went to the capital last time he went to the capital.
, It is precisely because this material is stronger that the performance of this shell is enhanced.
"Its core is 485 mm long, 27 mm in diameter, and the aspect ratio is 18." Qin Zhenhua introduced: "This kind of armor-piercing bomb should have a depth of more than 300 mm at a distance of one thousand meters."
More than 300 mm! When he heard this introduction, Old Huang's eyes flashed with surprise and admiration.
This performance has reached the performance of the 100mm smoothbore gun at the beginning!
Moreover, this is an older rifled cannon!
When it developed to the 69 tank, the rifled gun was replaced with a smoothbore gun, which was considered to be in line with the trend. As a result, the armor-piercing shell was not strong, and the depth of the piercing did not increase further. On the contrary, the shells were floating and could not be accurately hit, so this led to the 69 tank.
Replaced with a rifled cannon.
Later, Qin Zhenhua's subordinates developed a new type of shell, which made the penetration depth reach 320 mm, made an essential breakthrough, and gave the troops the strength to fight against the Northern Soviet Union.
However, there are many other situations to consider. The 100mm smoothbore gun is actually achieved by increasing the charge. In order to improve the performance of the tank gun, the volume of the launch cartridge must be increased.
Its launch cartridge is 9.4 liters, even larger than the 8.7 liters of the 105mm rifled gun. With more launching drugs and higher chamber pressure, the barrel will be thicker. Therefore, the weight of the 100mm smoothbore gun is very heavy
big.
During the competition, although the performance of the 105mm smoothbore gun did not exceed 100mm smoothbore gun, it was still introduced in China. This is because this rifled gun has greater potential.
Now, our 100mm rifled gun and the second phase of the bullet can already be as deep as the 100mm smoothbore gun, which is shocking.
Everyone's eyes were filled with anticipation, and Mr. Huang asked with a smile: "You just said that the depth of the wear should be more than 300 mm, and there is no specific data?"
Qin Zhenhua nodded: "Yes, because there is only one armor-piercing bomb at present, we are reluctant to test it. After all, the cost of this one is more than 10,000."
Everyone felt chills in their hearts. Qin Zhenhua said that the cost is so high?
"The warhead uses powder metallurgy technology, which is quite expensive." Qin Zhenhua said: "We originally showed it to foreign guests when they come."
No one does not want their tank to be more powerful. Although the penetration depth of the first phase of the bullet has reached 250 mm, there is no deepest, only deeper. After changing to new materials and adding aspect ratio, the
It reaches a depth of 300 mm, which is obviously more attractive.
Needless to say, the chief is a newer tank than the chief, and there is also the possibility of destroying it.
"I understand, you boy mean, now we all look at it, are you planning to let our troops reimburse the shooting cost of this armor-piercing projectile?" Old Huang pointed to Qin Zhenhua's head and said, "Sure enough, you boy and
Like Lao Zhao, he is no longer righteous. Since the country reforms and opening up, since the country has begun to adopt a market economy, one by one, has all been involved in the money eye!"
"Of course not. Since you are here, we have to fight if you shoot one thousand shots, even if you shoot one hundred thousand shots, we have to fight one hundred thousand shots." Qin Zhenhua said: "Now, please be careful with the leaders! Second pillar, come on!"
Wang Erzhu carried the shells and jumped onto the 69 tank.
Zhang Xiangqian drove the 69 tank that was about to exit and rushed to the shooting range with a bang. With a loud bang, the landslides and the earth cracked.
When the tank came back again, the special tank repair vehicle had already hung the target and started moving over. Seeing the target being pierced, everyone praised it.
The core of the elastic was just pierced inside, and it had just penetrated. Judging from the appearance of the penetrating passing through, it was definitely more than 300 mm.
"Three hundred and fifteen millimeters. The same as we calculated." Qin Zhenhua said: "Dear leaders, what do you think of our shells?"
"Well, it's good. It seems that although the price is a little more expensive, we can also purchase a batch. In this way, there is no need to replace the 100mm rifled gun. In comparison, it can save a lot of money."
