At today protection even the more modern Russian tanks such as the T-90 against cumulative and armor-piercing means (BPS) lesion needs to be strengthened. Expert assessments of growth of the power more presentable anti-tank shells and anti-tank should be, for example, that armor-piercing ability BPS tank guns modifications tank M1 "Abrams" is growing by approximately linear for-grabs aspect ratio of about 35 mm / year. If we talk about the cumulative anti-tank, then together with the growth of armor-piercing capabilities of combat units (BC) due to the growth of the caliber, increasing the power of explosive (HE) and the introduction of high-precision technologies in the manufacture of high-quality change occurs warhead impact on the protection of the principle, namely the transition to tandem warhead that can overcome the dynamic protection of the first generations, increasing the time delay between triggering the primary and secondary warhead, increasing the effectiveness of their actions through various kinds of circuit tweaks, etc.
Quite naturally, that to maintain parity required an adequate response from the defense of Russian tanks. The need for an urgent response steps in the direction of strengthening the security of Russian tanks is also dictated by the increase of its role in local conflicts, which dramatically increases the possibility of introducing anti tonkobronnyh side projections of the tank means close combat, such as antitank grenade (RPG) cumulative actions.
Task to create a complex security was given to the spices of "Institute of Steel". The result has been developed and adopted for complex frontal protection "Relic" and made initially to protect against RPGs light armored vehicles such as the BMP-3 specific modules DZ providing neporazhaemost board projections hull and turret of the common means of close combat type PG-9C.
After part of the body (in the engine department) and towers covered with latticed screens, reducing the possibility of formation of a cumulative jet funnel BC GHG by more than half due to violation of the regular functioning of the warhead in contact between the edges of the lattice.
Both complexes are fundamentally new. Thus, complex "Relic" is based on the element of explosive reactive armor (ERA) over-sensitivity 4C23 in Tumen and modern, more efficient throwing the scheme, in which dominates the destructive and destabilizing effect on the amazing elements of ammunition (cumulative jet, the core BPS) relatively thick armor plates, methane in the opposite direction. With all this the predominant contribution to the designated destructive effect puts record, Metal "vdogon." Thanks to the energy-throwing "vdogon" profitable than throwing towards, on the structures of this kind are implemented significant (4-5 times) Increase resistance by BPS in comparison with the serial RS complex "Contact-V» and immediately grow significantly "protivotandemnye" Features such armor, ie it acquires resistance against the most modern anti-tank tandem type TOW-2A with a time delay of more than 400 ms and armor penetration for hanging protivokumulyativnymi DZ more than 1000 mm. So Makar, the appearance of the complex "Relic" on Russian tanks — is a significant jump in security, providing protection against the majority of the most modern anti-tank weapons horizontal fire created to defeat the tank from the front projection.
According to estimates of professionals expressed during the exhibition in Nizhniy Tagil, "Relic" were made at the Institute, is the appropriate response to modern anti-tank weapons. Now it is one of the best security systems for armored vehicles, as well as the ability to install it on the new and modernized and in-use tanks to make a "relic" truly unique.
Ensuring the security of on-board projections of anti-tank grenades cumulative been taken from technical solutions, used for light vehicles by weight category (LMC). With regard to the protection coatings decision tasks was significantly more complex due to several limitations:
-it was necessary to organize the process of initiation of explosives and spreading plates so makarom to warn their destructive impact on the relatively narrow primary armor;
— required to prevent the transmission of detonation triggered when the cumulative effects of jet-charge explosive reactive armor (EDZ) on the entire volume of the block;
— on the ability of a very localized area of damage, limiting it to an area of one or two modules;
-give protection modules versatility, referring to the simultaneous strengthening protection for kinetic means of destruction, such as the bullet caliber to 14.5 mm, and a small-caliber gun shells.
All listed complex problems largely been solved by the development and production of weapons on EDZ ind. 4S24 with twice reduced in comparison with the EDZ 4S20, 4C22 amount of explosives. This allowed without reducing the effectiveness of struegasheniya dramatically improve the survivability of the shelling constructive and actually remove the flammability of both the EDZ and modules in general, that the former EDZ type 4S20 was problematic.
It should also be highlighted that when developing the complex was able to solve a very complex puzzle delay of favorite part of the jet, which is due to the inertia of the expansion plates DZ (in particular, methane vdogon) can "jump", holding with all this sufficiently high for a relatively narrow main armor armor-piercing capability of more than 1-caliber warhead.
It should also be noted that complex "Relic" means the installation of a tank complex means reducing the visibility of high-precision weapons, the main component of which is a set of anti-radiation multispectral composite "Cape", extensively tested and it proved.
Even the usual visual inspection machines indicates that significantly reduced the percentage of so called "weak spots".
Given that exhibited protective systems — is only part of a larger work on the deep modernization of the T-90, made "Uralvagonzavod" in virtually all of the nuances of increas
ing the combat effectiveness of the machine, it can be concluded that both our army and zabugornye partners in the case of purchase of such machines get one of the best tanks in the world, capable of current threats.
With all this potential for growth both protection and other combat machine properties conceals within itself a lot of reserves.
