New reactive armor? Hearing Andrey's words, Kartsev's eyes lit up. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

At present, the Soviet Union's armor development has been at the world's advanced level, so the Soviet tank mainly relies on composite armor to increase its protection ability, until later generations, when it was found that its own tank main armor could not block the advanced ammunition of the Western 105 mm tank gun, let alone the Western 120 mm tank gun, the Soviet Union began to quickly develop reactive armor and equip it on its own tank.

And now, the Hokkaido War, which has never been seen in history, has broken out, in which the T-72 has shown its inferior armor performance and can be penetrated by the 105-mm tank guns of the island nation!

This is still an armor-piercing shell of the island nation, if it were more advanced ammunition from the British and Americans, it could penetrate at a greater distance! Therefore, it is necessary to increase the armor protection of the T-72 tank!

If the same armor structure as the T-64 is adopted, it will greatly increase the cost and affect the large number of equipment of your own tanks, and Andrey, for example, put forward a new proposition, with reactive armor!

The tank is still built according to the original, and after it is built, just hang reactive armor on the outside! It was only previously limited by the performance of reactive armor that the USSR was forced to abandon this technology.

Now, hearing Andrei say it, the eyes of all the technicians are shining.

"Explosives can be sandwiched between two layers of steel plates, and this explosive is a dull explosive, so that machine gun bullets and shell fragments cannot penetrate this layer of steel at all, and therefore cannot detonate reactive armor. Insensitive explosives, on the other hand, will only detonate when they encounter a metal heat flow. Andrei said: "That's it. The problems encountered by the previous reactive armor can be solved. ”

Hearing this, Kartsev nodded and praised: "Yes, this will solve the problems encountered by reactive armor!" Andre. You're so smart! ”

"I was also reminded of the proposal that Dr. Helder had proposed." Andrei said: "With a pen, I can draw the structure of the reactive armor that I envisioned. ”

Pens, pen and paper were quickly brought, and the paper was spread on the flat armor behind the T-72, and Andrei drew it.

"The outer layer, which can be made of 3 mm steel plates, is placed in the middle of two armor steel plates with a thickness of 15 mm arranged at angles, one of which is a throwing plate and the other is a back plate, and the gap between the steel plates is filled with insensitive explosives. The overall dimensions are 250 mm x 138 mm x 103 mm. About 350 grams of insensitive explosives are added to it, such as semtine plastic explosives. Andrei explained: "In this way, when the metal jet penetrates the shell and the throwing plate, it detonates the insensitive explosive located in the middle of the steel plate, and under the impetus of the explosive explosion wave, the throwing plate flies outward and the back plate moves in the opposite direction, and the throwing plate pinches the head of the jet, cutting off the sharpest part of the jet and consuming the jet." The jet is then tailed by the backplate. It causes great disturbance and interference to the jet, further reducing the penetration of the jet on the main armor. Anti-tank weapons such as RPGs and anti-tank missiles, which are pierced through the tank's armor by metal jets, can be greatly mitigated. ”

This is what Andrei is talking about, that is, the contact-1 reactive armor that the Soviet Union officially equipped the troops with in the eighties. More advanced than the technology proposed by the Germans, the clever use of wedge-placed steel plates caused the explosives to produce asymmetrical detonation waves, pushing the steel plates to quickly and violently consume and cut the jet. Better results were obtained.

"However, this device is just better for metal jets. The ability to protect against armor-piercing bullets, I'm afraid it's average, right? "That's when it happened. Another technician asked.

Sure enough, it is the layman who looks at the excitement, and the insider who looks at the doorway! The idea put forward by Andrei made all the tank soldiers extremely excited, and his eyes were full of admiration when he saw Andrei, but these technicians immediately thought of a more difficult problem, how to prevent armor-piercing bullets?

After all, for tank crews, the biggest threat is the enemy's tanks, and in tank combat, the proportion of armor-piercing shells used is increasing, and in later generations, tanks are even equipped with only armor-piercing shells and grenades.

If it is not armor-piercing, then this reactive armor is still a failure.

"Then it has to be improved." Andrei said: "Another mechanism can be used to deal with armor-piercing bullets, which is the shear effect. Using two thicker high-hardness metal plates to move in the opposite direction, it is equivalent to scissors to cut off the flying nail piercing rod. ”

If you only rely on improving the strength of the armor to resist the flying armor-piercing projectiles, the armor will have to become thicker and thicker, which is quite unrealistic, so it has to be improved from the structure, and this shear effect is relatively good for dealing with armor-piercing bullets, which is also the principle of action of the constrained armor of later generations.

Andrei is familiar with these principles, and now, having met a tank designer, he can just elaborate on his own knowledge and improve the level of his own tanks.

The kind of scene in the future where the T-72 was easily killed by the Yankees will not appear!

"The explosive reactive armor I just talked about, can solve the problem of armor fragmentation, it has a throwing plate and a back plate, these can be used as scissors, although the high-strength warhead that cuts the continuous flying, but the kinetic energy of the attenuation warhead, it is still possible, in order to achieve good results, we can combine the 3 explosive reactive armor units just mentioned together, each unit has a 10 inverted 15 mm thick throwing plate and a back plate, and the unit group is equipped with a blunt explosive. In this way, in the process of being penetrated by the armor-piercing rod, the throwing plate and the backplate move in the opposite direction, plus the thickened steel shell outside, and the three complete the destruction process of the armor-piercing rod together up and down. Andrei said.

This is just the basic principle, and when it is developed, there will be various engineering problems, of course, these are not the scope of Andre's consideration, Andrei only talks about the principle.

When André said this, he felt silence around him.

Kartsev's brain was like a roof in an instant, yes, why didn't he think of it? The back and forth movement of the steel plate can just use the Coriolis force to counteract the energy of the warhead!

"Comrade Kartsev?" Andre waited for a full three minutes, seeing that the other party still didn't speak, Andre couldn't help but ask.

"Andrey, what a great idea you have!" Kartsev said: "It's too condescending for a talent like you not to engage in tank design, can I hire you to be our chief designer in Nizhny Tagil?" ”

"Comrade Kartsev, I still have a lot of small ideas." Andrei snickered in his heart. (To be continued.) )
