How does non explosive reactive armor work?
NERA (Non-Explosive Reactive Armor) consist of an dense elastomer interlayer compressed between two metal plates, or flyer plates. On impact the elastic material will compress to the point of maximum compression, until expanding again and bouncing back, forcing the plates to bulge.
What is explosive reactive armor made of?
An element of explosive reactive armour consists of a sheet or slab of high explosive sandwiched between two plates, typically metal, called the reactive or dynamic elements. On attack by a penetrating weapon, the explosive detonates, forcibly driving the metal plates apart to damage the penetrator.
What explosive is used in ERA?
C4 explosive
The ERA sandwich consists of two A36 plates with C4 explosive sandwiched in between. The ERA plates are 150 × 150 × 5 mm in dimensions, and the C4 explosive is 3 mm thick.
Does ERA stop Hesh?
ERA block will be destroyed to stop the jet. -HESH cannot begin shockwave on an alive ERA block. ERA block will be destroyed to stopping the effect….

Why is explosive reactive armor so effective?
Explosive reactive armour. An important aspect of ERA is the brisance, or detonation speed of its explosive element. A more brisant explosive and greater plate velocity will result in more plate material being fed into the path of the oncoming jet, greatly increasing the plate’s effective thickness.
How does plate tectonics affect reactive armor?
As the plates bulge, the point of jet impact shifts with the plate bulging, increasing the effective thickness of the armour. This is almost the same as the second mechanism that explosive reactive armour uses, but it uses energy from the shaped charge jet rather than from explosives.
Do explosive reactive armors disrupt jet penetration?
The disturbance of explosive reactive armors on jet penetration was studied in this paper. Most ERA has a sandwich configuration consisting of a front plate, an interlayer explosive, and a rear plate.
What is Kontakt-5 explosive reactive armor?
The advanced Kontakt-5 explosive reactive armour on this T-90S is arranged in pairs of plates, giving the turret its prominent triangular profile. Explosive reactive armor (ERA) is a common form of add-on armor employed in many armored fighting vehicles (AFVs), such as tanks.
