One of the first new developments was the use of explosive reactive armour (ERA), developed by Israel in the early 1980s to defend against the shaped-charge warheads of modern anti-tank guided missiles and other such high-explosive anti-tank (HEAT) projectiles. Upon impact with a hollow jet explosive charge, the incompressible layer causes the outer metal sheets to push outwardly into the path of the hollow jet explosive charge. 2) RHA with no Composites or ERA with the protection of 55mm Kinetic Protection and Shaped Charged Munition Protection Against a kinetic energy penetrator, the projected plate⦠explosive reactive armor, but features a reactive material that reacts much slower than explosive reactive armor. "We are considering explosive reactive armor, non-explosive reactive armor, smart armor, electromagnetic armor. reactive armor systems and was classified by the US DOT as a very insensitive detonating substance in accordance with UN safety standards. These rounds are very effective against older generations of tanks which lack these explosive reactive armours and composite armours. CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Studies of non-explosive reactive armour, NERA, as add-on armour against shaped charge warheads, has been performed with focus on the effect of introducing more than one consecutive panel and the in-fluence of the mutual orientation of the panels. It is effective against reactive armour, which is designed to protect an armoured vehicle (mostly tanks) against anti-tank munitions. However, NERA is not as effective as ERA for protecting Kinetic Energy threats. This explosive does not detonate or burn when hit by bullets, projectiles, or fragments. Non-Explosive Reactive Armour was installed over the original hull. The most common type is explosive reactive armour (ERA), but variants include self-limiting explosive reactive armour (SLERA), non-energetic reactive armour (NERA), non-explosive reactive armour (NxRA), and electric reactive armour.

Non-Explosive Reactive Armour achieves the same effect without an explosive layer. Most ERA has a sandwich configuration consisting of a front plate, an interlayer explosive, and a rear plate. What does NERA stand for? It can be integrated into the vehicleâs primary armour or employed as modular or applique armour attached over the vehicleâs organic armour. INTRODUCTION INL researchers have proposed prototypes for future lightweight armor systems that reside in a technology gap between explosive-reactive armor and passive armor. The explosive ⦠During a reactive encounter, this explosive causes minimal environmental and collateral damage. Passive armour is any kind of armour that doesnt react against muntions or activate in any kind fo way. Explosive reactive armour (ERA) ,,NEXREARMâ is armour protection system able to significantly reduce penetration of shaped charge warheads and kinetic energy projectiles, thereby ensuring the non-perforation of the tank armour and protection of the crew. The loads from NERA inflicted on the vehicleâs structure are much smaller than ERA, and therefore can be applied to lighter vehicles. Each reactive element consisted of a three milimeter steel plate, a three milimeter thick layer of ⦠However, insufficient theoretical analysis during one of the tests resulted in all of the prototype elements being blown up. TM Before After Another type of non-metallic ERA is the CLARA, developed by Dynamit Nobel. Armor with two or more plates spaced a distance apart falls under the category of spaced armour.Spaced armour can be sloped or unsloped. Therefore, they provide an effective multi-hit protection capability which cannot be obtained by ERA(here E is for explosive) or SLERA. Armour. It is most effective in protecting against shaped charges and specially hardened long rod penetrators. Against a shaped charge, the projected plates disrupt the metallic jet penetrator, effectively providing a greater path-length of material to be penetrated. Above test was an inert reactive armor test, an explosive reactive armour test gave this result: (part B is the same as "t = 30 microseconds" in the first picture) Interesting to note that the first ~5 cm of the jet in the inert test isn't damaged, but is in the explosive test. Tandem charges are effective against reactive armour, which is designed to protect an armoured vehicle (mostly tanks) against anti-tank munitions. The loads from NERA inflicted on the vehicle's structure are much smaller than ERA and therefore, can be applied to lighter vehicles. James Bingham assesses developments in reactive armour technologies, including explosive and non-explosive reactive armour and electric armour. The explosive-filled packages could help the ⦠The first pre-production models were produced during the 1960s. INL researchers have proposed prototypes for future lightweight armor systems that reside in a technology gap between explosive reactive armor and passive armor. Meaning of reactive armour. They weigh a "mass" of 80 to carry. C. Non-Explosive Reactive Armor (NxRA): Non-Explosive Reactive Armor provides a comparable efficiency to SLERA, comparable survivability to NERA (see below), and excellent multiple-hit capability against hollow charge warheads. These include self-limiting explosive reactive armor (SLERA), non-energetic reactive armor (NERA), non-explosive reactive armor (NxRA), and electric reactive armor. However, some older IDF APCs, such as the Zelda series have been known to utilise ERA.

The idea of counterexplosion (kontrvzryv in Russian) in armour was first proposed by the Scientific Research Institute of Steel (NII Stali) in 1949 in the USSR by academician Bogdan Vjacheslavovich Voitsekhovsky (1922â1999). Not all reactive armour is explosive however- IDF APCs such as the Namer use likely non-explosive reactive armour, which Tandem-charge warheads are of lesser effectiveness against. Reactive armour was first patented in West Germany in 1970, but Israel was the first nation to introduce it operationally, deploying RA-equipped M-60 tanks during the Lebanon War of 1982. There are various categories of reactive armour, including Explosive RA (ERA), Non-Explosive RA (NERA), and Electric/Electromagnetic RA. Reactive armour is a type of vehicle armour that reacts in some way to the impact of a weapon to reduce the damage done to the vehicle being protected. The TB-5 Non-explosive Reactive Armour is a heavy plate that protects the side, taking out high calibre munitions that penetrate the upper armour by releasing a high power discharge, vaporising them, though is compromised after this. 2.1.6 The analysis presented within this document was able to determine that, within the scope of the Medium Weight Vehicle context, a practical EA system would be likely to outperform conventional and Explosive Reactive Armour NERA and NxRA modules can withstand multiple hits, unlike ERA and SLERA, but a second hit in exactly the same location may potentially penetrate any of those. The most common type is explosive reactive armour(ERA), but variants include self-limiting explosive reactive armour(SLERA), non-energetic reactive armour(NERA), non-explosive reactive armour(NxRA), and electric reactive armour. It gave the advantage however that it worked against all types of ammunition, often breaking the penetrating rods of AP rounds. The first type of explosive reactive armor adopted on a tank was Blazer ERA. Reactive armor is a type of armor that reacts to the penetrator. Not deflecting the explosion away. Explosive Reactive Armor (ERA), read this, all... Explosive Reactive armor (ERA) is a common form of add-on armor, used on many Armored Fighting Vehicles (AFV). Other applications of reactive armor are based on the use of reactive properties of the protection module, yet the initiation of such reactions are not triggered by an explosive charge. U.S. Army soldiers in Europe are adding extra protection to their M1A2 Abrams main battle tanks in the form of explosive reactive armor. Main battle tank-Wikipedia Non-Explosive Reactive Armor (NERA or NxRA) uses passive material, such as rubber, sandwiched between two metal plates. Reactive armour (RA) is designed to neutralise the impact of shaped-charge warheads and kinetic penetrators.
