Yes, Zhenhua is right, we really have to think about it, so, now, can you tell us what you really think? Huang Lao said: "Don't worry about anything, just say whatever comes to mind." ”

This young man has a lot of aggressiveness and a broad vision, so Huang Lao wants to hear his opinion.

Zhang Lao also nodded again and again: "That's right, I'm here for you, if anyone dares to trouble you because of this afterwards, I'll beat his ass for you." ”

The crowd burst into laughter.

In this, there must be some interests involved, for example, the second machine factory also came, the team that developed the 120 mm tank gun, in it, if Qin Zhenhua vigorously advocated the benefits of the 120 mm tank gun, maybe their project could go on until the final success, if Qin Zhenhua belittled it was worthless, then the project would be gone.

Several people from the Second Machine Factory had really looked over at this time, looking at Qin Zhenhua, expecting Qin Zhenhua to say something.

"First of all, all other things being equal, the larger the caliber of the gun, the more the charge is charged, the greater the energy of a cannon will definitely be, and there is no problem with this." Qin Zhenhua said: "However, because the 125 mm tank gun is too heavy, then it can only be divided into parts, and this division will bring about the problem of loading, so it is necessary to get on the automatic loader, otherwise, the rate of fire will be pitiful." ”

This is the route to the final solution of a series of problems, the caliber is large, the shells are heavy, the loading is divided, and after the subloading, you have to go to the automatic loader.

"The automatic loader reduces the labor burden of the tanker, but at the same time, on the other hand, whenever the machine is a machine, it will break down, which will increase the failure rate of the tank." Qin Zhenhua said: "On the other hand, what is more serious is that I don't like it very much, and I always feel scared when I am surrounded by ammunition in my body. My guts are very small. ”

Qin Zhenhua's courage is not small, after all, he is a combat hero and dares to see red with a bayonet, but now, he is afraid when he says it, of course, there is a reason.

Anyone can imagine the consequences of this round of ammunition once it is detonated.

"As for the other aspect, it's the shells." Qin Zhenhua said: "We know that tank guns are mainly used to hit the enemy, and the main force of the bullets fired is the tail stabilized shelling armor-piercing shell, the larger the length-diameter ratio of this kind of shell, the higher the armor-piercing ability." ”

Qin Zhenhua's analysis said: "Take our current 105 mm artillery shell as an example, we plan to use a longer piercing rod, which has already extended the piercing rod into the firing cartridge, so that the length of the warhead can be increased while saving the overall length, but the sub-loading ammunition does not have this benefit, and the length it can use must be limited." ”

Only a few years ago, China was still dominated by blunt-headed armor-piercing shells, and Qin Zhenhua's father died in the development of this sub-caliber armor-piercing projectile, and Qin Zhenhua's research on this kind of artillery shell is also the most in-depth.

The longer the warhead, the better, and now the warhead has begun to be stuffed into the back shell, the longest, all the way to the end! Of course, it is impossible to be unlimited in the length of the material limited by the projectile body, but as long as there is a better material in the future, there is this potential.

And what about the shells in separate packs? This potential is absent, and if it is packed separately, it is impossible to become a whole, that is, the potential of such shells is limited and difficult to tap!

Huang Lao said solemnly: "In other words, the final power of a 125 mm tank gun may not be as good as a 120 mm tank gun?" ”

"This, we will not know until later, as far as the current point of view, the shells of the Soviet 125-mm tank guns are not comparable to the power of the German 120-mm tank guns. Of course, their own use, we don't know, can only be a guess. Qin Zhenhua said.

After talking about the advantages and disadvantages of this, Qin Zhenhua began to talk about the 120 mm tank gun again.

"As for this 120-mm tank gun, if you dig deeper, the armor-piercing depth will break through five hundred millimeters, or even reach the level of seven or eight hundred millimeters, I think it is possible." Qin Zhenhua said.

After all, the armor-piercing depth of a 105-mm tank gun has already exceeded 300 mm, and the potential of this 120-mm tank gun in the future must also be great.

"However, its disadvantage is that it is inconvenient to arrange an automatic loader." Qin Zhenhua introduced: "The warhead and cartridge are integrated, so they are very high, and they cannot be arranged around the turret in a circle like the T-72. ”

The idea of solving the problem in the East and the West is different, the Western tanks are made tall and large, especially the turret, look at the volume of the turret, it is almost twice the relationship, especially behind the turret, there is also a redundant tail compartment, this tail compartment is used to put shells.

Stacked shells are easy to deploy an automatic loader, but the turret is large and heavy, so it brings a lot of problems, for example, when the turret is rotated, it has to be driven by a larger hydraulic motor, and the inertia is also very large, and the tall turret increases the bomb area, and the increased weight requires greater power to drive, so that the bigger and bigger it is, and finally, it becomes the same thing as the Leopard-2 that weighs more than 50 tons.

Therefore, with a 120 mm tank gun, there are also many problems, without deploying an automatic loader, manual loading, it has to be a big guy, and the turret of the tank has to be large enough.

"Well, after talking for a long time, it's still equivalent to not saying anything." Huang Lao said with a smile there: "You kid, now you are also driven by the bad atmosphere within the system, this is no one can be offended, left and right." ”

"Of course not." Qin Zhenhua's answer was righteous and strict, I am on the matter, I really don't know which one is better, if I can be sure, then I will definitely say it on the spot.

I'm going to leave the system, am I still afraid of offending people? I have offended many people!

"Elder Zhang, I have an idea." Huang Lao said: "This kid refuses to say one, two, three, I still want him to say, give the demonstration of the caliber of our next generation of tank guns to this kid!" ”

"Don't, don't." Qin Zhenhua immediately became anxious, this kind of thing, the responsibility is too heavy, how can a young man like me take on the task of demonstrating the caliber of the next generation of tanks in the motherland! I can't carry this shoulder.
