Protection
Additional
protection package for T-55AGM tank
The additional protection package is intended to
increase the level of protection of the tank against chemical energy
attack as well as kinetic energy attack (APFSDS) with the minimum
possible increase of tank weight.
The additional
protection package consists of passive armour protection and
explosive reactive armour.
The tank hull nose is fitted with a removable module.
The hull sides are fitted with armoured skirting plates as well as
rubberised fabric skirts.
The outer perimeter of
the front and side parts of the turret is fitted with module sections
while the turret roof is fitted with containers of the explosive
reactive armour array.
Each section and each container contain explosive
components of explosive reactive armour of new generation, designated
Nozh.
The protective action of
the explosive reactive armour against a chemical energy attack
consists in destruction, crushing and changing the direction of the
high-energy jet due to action of the explosive reactive armour
fragments and products of detonation of the explosive that is stored
inside the explosive reactive armour component and is initiated by
the high-energy jet.
The protective action of the explosive reactive armour
against a kinetic energy attack projectile consists in destruction of
the projectile body and changing of the direction of its penetration
due to action of the products of detonation of the explosive that is
stored inside the explosive reactive armour component and is
initiated by the kinetic energy of the projectile.
Installation of the explosive reactive armour increases
the level of protection of the T-55AGM tank as follows:
-
against chemical energy attack - by a factor of
2.3-2.6;
-
against kinetic energy attack - by a factor of
3.5-4.3.
The
explosive reactive armour components do not detonate when hit by
small arms bullets (7.62 mm and 12.7 mm in calibre) or automatic
cannon rounds (up to 30 mm in calibre). Nor do they detonate when
exposed to action of incendiary substances of Napalm type or
destructive effects of volumetric explosions.
Vehicle
signature reduction means
Dazzle
coating of the external surfaces of the tank makes it less liable to
be detected in the visible and near-infrared ranges of spectre when
the enemy is observing the terrain through optical devices, image
intensification night vision devices or low-level television cameras.
The thermal insulation of the power pack compartment top deck makes the
tank less liable to be detected by enemy thermal imaging systems or
to be sensed by homing warheads of missiles (projectiles, mines)
which find targets by using thermal contrast. |
