Chapter four hundred and eighty third each has its own merits
"Yes, Zhenhua is right. We really need to think clearly. So, now, can you tell you your true thoughts?" Huang Lao said: "Don't have any worries, just say whatever you think."
This young man has a strong sense of adventure and a broad vision, so Mr. Huang really wants to listen to his opinions.
Mr. Zhang also nodded repeatedly: "Yes, I'll take care of you here. If anyone dares to cause trouble for you later, I'll beat him up in the butt."
Everyone burst into laughter.
There must be some interests involved. For example, the second machine factory has also come, and the team that develops 120mm tank guns is among them. If Qin Zhenhua vigorously advocates the benefits of 120mm tank guns, perhaps their project can continue until it is successful in the end. If Qin Zhenhua belittled by him, the project will be gone.
The few people from the Second Machinery Factory had indeed looked at Qin Zhenhua at this time, looking at Qin Zhenhua, looking forward to what Qin Zhenhua said.
"First of all, under the same conditions, the larger the caliber of the artillery and the more the launching medicine is installed, the greater the energy of the shot. There is no problem with this." Qin Zhenhua said: "However, because the 125mm tank gun is too heavy, then you can only use the method of partitioning, and this partitioning will bring about the problem of loading, so you must use an automatic loading machine, otherwise the rate of fire will be pitifully low."
This is the final solution to a series of problems. If the caliber is large and the shells are heavy, they must be loaded. After the assembly, they must be loaded on an automatic loader.
"The automatic loading machine reduces the labor burden of the tank hands, but at the same time, on the other hand, any machine will fail and increase the failure rate of the tank." Qin Zhenhua said: "On the other hand, what's more serious is that I don't like it very much. I always feel scared of ammunition in a circle of body. My courage is very small."
Qin Zhenhua is very brave. After all, he is a combat hero and dares to become famous. But now, he says he is afraid, so of course there is a reason.
Anyone can think of the consequences of this circle of ammunition once exploded.
"As for the other aspect, it is the shells." Qin Zhenhua said: "We know that tank guns are mainly used to attack the enemy. The type of shells fired is the main force of the tail wing stable shell-piercing armor. The larger the length-to-diameter ratio, the higher the armor-piercing ability."
Qin Zhenhua's analysis said: "Take our current 105mm shells as an example. We plan to use a longer pole, which has already extended the pole into the launch cartridge, so that the length of the warhead can be increased while saving the overall length. However, there is no benefit in packing ammunition. The length it can be used must be limited."
Just a few years ago, in China, the era was still the main era of blunt-head armor-piercing bombs, and Qin Zhenhua's father died in the development of this sub-caliber armor-piercing bomb. Qin Zhenhua's research on this artillery shell is also the most in-depth.
The longer the warhead, the better. Now the warhead has begun to be stuffed into the shell behind it. The longest can be done to the end! Of course, due to the material of the bullet body, it cannot be infinitely long, but as long as there is better material in the future, it will have this potential.
What about the cannonballs that are packaged? There is no potential. If they are installed separately, they cannot become a whole. In other words, the potential of this cannonball is limited and difficult to explore!
Huang Lao was solemnly speaking: "In other words, the final power of the 125mm tank gun may not be as powerful as the 120mm tank gun?"
"We will only know this later. As of now, the shells of the Soviet Union's 125mm tank gun are not as powerful as those of the German 120mm tank gun. Of course, what they use for themselves, we don't know, can only be a guess." Qin Zhenhua said.
After talking about the advantages and disadvantages of this kind, Qin Zhenhua began to talk about the 120mm tank gun again.
"As for this 120mm tank gun, if you dig deep, the armor-piercing depth will exceed 500mm, or even reach the level of 7008mm, I think it is possible." Qin Zhenhua said.
After all, the 105mm tank gun has a armor-piercing depth of more than 300mm, and this 120mm tank gun will inevitably have great potential in the future.
"However, its disadvantage is that it is inconvenient to arrange the automatic loader." Qin Zhenhua introduced: "The bullet and the bullet barrel are integrated, so they are very tall and cannot be arranged around the turret like the T-72. If you want to arrange it, you can only have a large turret like the West, which is arranged in the tail of the turret, so that the need for automatic loading is met in this way."
The East and the West have different ideas for solving problems. Western tanks are made high and large, especially for turrets. Looking at the size of the turret, it is almost twice as large. Especially behind the turret, there is an extra tent, which is used to set off shells.
The shells stacked together are easy to deploy automatic loaders, but the turret is large and heavy, so there are many problems. For example, when rotating the turret, it requires a larger hydraulic motor to drive it, and the inertia is also very high. Moreover, the tall turret increases the area of the ammunition and the weight increases, so that it requires greater power to drive it. In this way, the bigger the turret becomes, and in the end, it will become something with a weight of more than fifty tons like the Leopard-2.
Therefore, there are many problems with using a 120mm tank gun. If you don’t deploy an automatic loader or manually load it, you must be a big guy, and the tank’s turret must be large enough.
"Okay, after talking for a long time, it's still equivalent to not saying anything." Old Huang said with a smile: "You kid, you are now driven by the bad atmosphere inside the system. This is not an offense to anyone, and you can get along with everyone."
"Of course not." Qin Zhenhua's answer was righteous and stern. I was just talking about the matter. I really don't know which one is better. If I can be sure, I will definitely say it right now.
I'm planning to leave the system, are you still afraid of offending people? There are quite a few people I offended!
"Old Zhang, I have an idea." Old Huang said: "This kid refuses to say one, two, and three, and I insist on letting him say that we will leave the argumentation of our next generation of tank gun caliber to this kid!"
"No, don't." Qin Zhenhua immediately became anxious. The responsibility for this kind of thing is too heavy. How can a young man like me take on the task of a caliber argumentation of the next generation of tanks in the motherland? I can't bear it on my shoulders.
