"Forehead ......"

Chen Yaoyang was right, when determining the modification plan of T-34\85, the smoker and the imitation version of the "Sparrowhawk" infrared night vision system are okay, the key is that the reactive armor used to enhance protection cannot be taken out for a long time.

There is no other reason, but because Bai Yi is not the current polyurethane-filled additional armor at all, but the blasting reactive armor with excellent protection against both armor-piercing and armor-piercing shells.

The principle is to use the recoil force of the explosives set inside the armor module to counteract the metal jet of the armor-piercing projectile and the alloy warhead of the armor-piercing projectile, which is much better than the polyurethane-filled additional armor that can only produce some resistance to the armor-piercing projectile.

However, it is precisely because of the excellent performance of blasting reactive armor that it is also very difficult to develop, especially the two key technologies of explosive passivation agent and directional explosion control, not to mention in the early 50s, even in the early 21st century, decades later, it is also the core technical difficulty in the field of armor.

Let's talk about the explosive passivator first, if there is no such synthetic reagent to reduce the sensitivity of explosives, a tank with explosive reactive armor is no different from a self-detonating truck that goes to die, as long as the enemy fires a bullet, the tank can blow up into the sky along with that piece of blasting reactive armor.

Therefore, explosive passivation is indispensable, and after solving the problem of passivating agent, that is the more critical amount, using more explosives will become unresponsive, even if the anti-tank ammunition from high speed hits the blasting reactive armor, the explosives in it will not detonate.

If it is used less, it may be possible that the enemy's small-caliber ammunition will be able to cause the blasting of reactive armor before the lethal anti-tank ammunition has been easily destroyed, and the tank that has been pulled out of a layer of skin will naturally not be able to escape the enemy's real killing moves.

Therefore, the use of passivating agent can neither make the explosive too sluggish, nor let it detonate in advance, but to turn on the explosion anti-shock mode after the real threat of anti-tank ammunition, which is the best performance indicator.

This involves a large number of calculations of the lethality, kinetic energy and armor-piercing indicators of the current mainstream anti-tank ammunition, as well as a large number of tests in the synthesis of passivates and explosives.

The same is true for the other key explosive directional blasting, which requires unimaginable calculations and tests to find a balance between blocking incoming anti-tank munitions and ensuring the safety of adjacent equipment on other tanks.

Otherwise, if it is allowed to explode, it may not only cause a large number of other armored modules to be destroyed, but also cause unimaginable damage to the tank sighting device and even personnel.

Because of this, even if the blasting reactive armor on the second- and third-generation tanks of various countries is covered with a lot of them a few decades later, it is only the work of those few military-industrial powers.

It stands to reason that today's China can't afford to play, the calculation is fine, there is no computer, and those Chinese scientific and technological personnel will work overtime to calculate the required data even if they use an abacus, which is nothing more than a little longer.

The key is the test, you must know that the passivation agent used to blast the reactive armor is not cheap, one or two tests are okay, if it is thousands of tests, the snowflake silver that blows up the white flowers is no different.

But fortunately, Bai Yi, a graduate student of military equipment in his previous life, still has some understanding of China's "FY" series blasting reactive armor, coupled with the help of Stuttberg, a former German military chemical master, can greatly reduce the amount of relevant tests.

Otherwise, even if the Baiyun Plant smashes the pot and sells iron, it can't support this real money-burning move, but Rao is so, the Baiyun Factory's scientific research funds this year have also been consumed because of the blasting of reactive armor, so that those indispensable calculations and tests can be completed in more than a year.

In this way, this kind of explosive reactive armor will inevitably not be able to catch up with the current Korean War, and it will not be able to talk about the realistic spirit of finding a practical way to equip equipment in actual combat, as hoped by the chief of armaments.

Therefore, Bai Yi will pay close attention to the development of blasting reactive armor on the one hand; On the other hand, polyurethane padding is used as a temporary substitute for blasting reactive armor.

After all, this kind of additional armor developed by the Soviet Union in the early 70s and designed to resist armor-piercing shells adheres to the consistent idea of quantity and equipment, simple, effective, and convenient to manufacture, even China, which has no tank armored vehicle manufacturing technology today, has no difficulty in producing this additional armor.

Needless to say, those thin steel plates and welding processes, even if China's industry is backward, this processing capacity is still there, as for the polyurethane filler inside, the surgical gloves used in the hospital are still very easy to get, so this additional armor was made by Bai Yi in less than a week.

Because of this, in Bai Yi's opinion, it is simply too good for them to be able to tell them in advance what Lao Maozi will get out of twenty years later, where it is a pit.

So Bai Yi couldn't help but take a hard puff of cigarette, and then exhaled a long time, and then said: "I am also for the good of those Soviet comrades, besides, if it is really a pit, it is Zakharov who found it himself, but I didn't give it to me on the pole!" ”

"Let's see, let's be honest!"

"Aren't you too? My heart is like a mirror, but I don't say anything, if you want to say bad, you are really bad! ”

This time it was Bai Yi's turn to throw Chen Yaoyang a big eye, Chen Yaoyang neither admitted nor denied it, just laughed, he also went to the Soviet Union several times, although he was grateful for the Soviet Union's assistance, but he was still very tired of the chauvinism in the bones of the Soviet big brother, so he was also one of the few people who supported Bai Yi to keep a hand on the Soviet Union in technology.

It is precisely because of this that he will watch Bai Yi finish digging the pit with a cold eye, all in all, they are brothers who have been born and died for many years, and they have long known each other, so Chen Yaoyang extinguished the cigarette butt in his hand on the tank, straightened his waist and said his real worries: "I'm not afraid of anything else, I'm just worried about where the chief of armaments is, in this regard, you Lao Bai should know better than me, the chief of armaments wants to use this additional armor to go to the Soviet Union to find good goods, so I just gave it to others regardless of it, with the temper of the chief of armaments, You're not afraid ......."

"I'm afraid, but I'm still the same sentence, it's not good to chew too much, instead of doing so many miscellaneous things, it's better to concentrate on digesting the existing technology!"

Bai Yi also snuffed out the cigarette butt in his hand, and his words were resolute with an unconcealable ......
