Functions of explosive reactive armor «Duplet»
Explosive reactive armour modules «Duplet» are designed for protection of stationary objects and combat armored vehicles from armor-piercing shells, hollow charge hitting means and self-formed striking hollow-charge shells of “striking cannon-ball” type.
Application of explosive reactive armor «Duplet»
«Duplet» modules can be applied as part of built-in and mounted armor of tanks and light-armored vehicles.
If a grenade hits part of the combat vehicle protected with “Duplet” modules, fractures of the vehicle armor are excluded.
Installation of “Reactive armor” system with “Duplet” modules increases level of tank protection from hollow-charge and kinetic hitting means by 2-3 times.
Setup and operating principle of «Duplet» modules
«Duplet» modules can be replaced with “Contact” explosive reactive armor elements in proportion 1:2. One «Duplet» module is installed into a standard bed for installation of reactive armor of any construction instead of two 4S20 and 4S22 elements.
Decreased explosive effect of «Duplet» modules on the armor along with new construction of bed for installation of modules on the vehicle allows to upgrade survivability of explosive reactive armor by 2 times in comparison with “Contact” system.
Operation of «Duplet» system does not require special preparation before operation, maintenance and repair.
Installation of “Explosive reactive armor” «Duplet» modules increases level of tank protection from hollow-charge and kinetic shells by 1.5-2.5 when compared with best world analogues of explosive reactive armor like «Contact» and «Blazer».
Reactive armor based on «Duplet» modules favorably differs from the best world analogues in:
- Increased level of protection by 1,5 – 2,5 times;
- Ability to securely protect from all types of anti-tank means, primarily from armor-piercing subcaliber shells and self-formed striking submunitions of “striking cannonball” type;
- High reliability of elements operation;
- Protection from armor-piercing shells of small caliber guns;
- Security under fire of all caliber of bullets and fragmentation;
- Increased resistance to high temperatures and humidity.
- Generality of application on all types of combat vehicles;
Operation of «Duplet» modules
When the hollow-charge shell is approaching the vehicle, the cumulative stream initiates the elements inside the 'Duplet' module; each element is forming a directed stream of explosion fragments. Influencing the cumulative stream, the directed flows of explosion break the stream down into separate fragments, therefore damaging its integrity and continuity. This results in significant decrease and sometimes to full absence of armor-piercing effect of hollow –charge hitting means.
The explosive reactive armor based on ' Duplet ' modules installed on the basic tank, provides protection from 120 and 125 mm armor-piercing subcaliber shells from a distance of 100 m, hollow charge grenades, artillery hollow charge shells, anti-tank guided and unguided missiles, and subminitions of «striking cannonball» type.
Explosive reactive armor based on «Duplet» modules has been accepted to the arsenal of Ukraine.
