Chapter 801: Various Requirements (Additions)
"We are also working on an automatic loader." Qin Zhenhua said: "These should be known at the end of the year, our 85 tank, by the end of the year, will launch a further firepower modification to comprehensively improve the firepower performance." ”
Qin Zhenhua still went around his own 85 tanks and persuaded the other party to purchase his own 85 tanks, which is of course the most ideal.
What you want, will be realized on our 85 tank, don't look at the current 105 mm barrel, when it matures, you can replace it with a 125 mm tank gun, when it was designed, it was already considered.
"By the way, what level of armor-piercing capacity is the export model of the T-72 tank of the Soviets?" General Berg asked.
T-72 of the Soviets?
For personal use, that's hard to say, after all, no one knows, but the kind of export is definitely a chicken rib.
"The T-72 tank of the Soviets, the export model uses the core of the 3BM17 armor-piercing projectile." Qin Zhenhua introduced it according to the knowledge he mastered: "This kind of armor-piercing bullet uses a steel piercing rod, so the armor-piercing ability is very poor, according to the test, at a distance of two thousand meters, a penetration depth of 220 millimeters is good." ”
Even the special armor-piercing bullets on your own 100 slides can be compared! Qin Zhenhua is very confident in this.
In order to increase the depth of penetration, all countries are constantly using new materials, tungsten alloy is the most commonly used, especially the tungsten alloy core made by special powder metallurgy process, the length-diameter ratio can be further increased, and the Americans even use depleted uranium core.
And what about the Soviets? The export type is actually a steel core bullet! This is simply shrunk to the limit, blind to such a thick barrel in vain! This kind of penetration can even be blocked by your own 69 tanks.
"So, what about their own armor-piercing shells?" Berg continued.
"For personal use? No one knows this, but when the Soviets exported their T-72 tanks, the penetration depth given was 2000 meters to penetrate 310 mm of homogeneous steel armor, but in fact it was not up to at all, but when they purchased, they must have tested it, so, I guess, it is estimated that this penetration depth is the armor-piercing depth data of the Soviet army's own tungsten core bullet, after all, the tungsten alloy armor-piercing bullet of the Soviets is also a strange two interceptions. ”
Although the specific information is still confidential, many of them are still clear that this tall tungsten alloy armor-piercing bullet is not a thin and long bullet shaft, but is divided into two halves!
This should be a consequence of the poor metallurgical technology, made into a thin and long rod is easy to break, can only be made into two halves, how to fix these two halves together, that is, a knowledge, the solution of the Soviets is to use a steel sleeve, wrap it.
Even if it is for this kind of personal use, the performance is not good, and the 125 mm thick barrel is blinded in vain, and the penetration depth is only about 300 mm.
The Soviets naturally knew that their armor-piercing elastic performance was not good, so the Soviets were constantly developing new armor-piercing bullets, and in 1986, there were new 3BM42 armor-piercing bullets, which still used a steel-sleeved tungsten bullet core, and claimed to be able to penetrate 450 mm of homogeneous steel at a distance of 2000 meters
And now, Qin Zhenhua can roughly say these data, three hundred millimeters, should be the limit.
Although the armor-piercing ability of the T-72 armor-piercing bullets currently exported is not good, the Soviet Union may export it for its own use at any time, so it is still necessary to be wary of this.
Actually, these figures may sound bad now, but in the eighties, it was enough to deal with most of the conflicts.
Because in this era, most of the tanks are still ordinary armor steel, and the thickest part is just more than 200 mm!
Explosive reactive armor has just emerged, composite armor is still the highest thing, and a large number of armies in various countries are still equipped with the most ordinary tanks, so this kind of penetration is enough, and the Soviets have never pursued the top data, as long as it is enough.
"That is to say, the penetration depth of the T-72 tank is on the order of three hundred millimeters, and considering the potential for them to continue to upgrade, the frontal protection of our jointly developed tank must reach the level of 450 millimeters." Berg continued.
As soon as this data came out, several people were immediately startled.
Frontal protection, 450 mm?
In terms of design, the Eastern tanks mainly rely on low profile to enhance protection, and their own 85 tanks, with a height of only 2200 mm, are quite low, compared to the German Leopard 2 is 2480 mm, and the American M1 tank is 2885 mm. The lower the profile, the smaller the natural frontal projection area.
As for protection, our current tank is actually welded with the latest armor steel, although the protection is a lot enhanced, but compared to 450 mm, it is still far behind!
Even if you stuff the first-generation fiberglass composite armor developed by your own side, the protective power is about 400 millimeters, and then, the remaining 50 millimeters, do you rely on armor steel?
In this case, the weight of the tank will soar!
Even if it is its own third-generation tank, the data on the protection power presented so far is only 600 mm, and this is based on the 50-ton level.
Your own 85 tank is only 40 tons, and it is very difficult to achieve 450 mm protection capability, unless the 85 tank is overhauled!
Looking at Qin Zhenhua's contemplative appearance, the other party said: "We know that this indicator is a bit high, but our jointly developed tank is to achieve performance advantages on the battlefield in the future, as a third-generation tank in pre-research, we must have such high standards." ”
"If this is the case, then the weight of the tank will probably exceed 45 tons." Qin Zhenhua said: "The tanks you are operating now do not exceed forty tons, don't you worry about the restrictions on bridges and so on?" ”
Qin Zhenhua tried to convince the other party through other aspects.
Berg shook his head: "We're not worried. ”
"Okay, then we can develop according to this standard, in this way, the power of the engine will also be increased to about 1,000 horsepower, only our latest research and development of the Panther diesel engine, can meet your needs."
Now, this joint research and development project is already in its infancy, with a dead weight of at least 45 tons, a 125-mm tank gun and an automatic loader, plus a 1,000-horsepower diesel engine.
Will I finish it one step earlier than I wish them? Thinking of this, Qin Zhenhua smiled a little bitterly.
"So, let's move on to the issue of production, and when it is developed, we hope that this tank can be produced in our own factory."
