Who invented explosive reactive armor?

It was only until the 1970s that the first successful Explosive Reactive Armor was created and patented by the German researcher Dr. Manfred Held.

How much does explosive reactive armor weigh?

– Individual blocks are proof against effects of small calibre armour piercing incendiary munitions after impact ranging from 12.7 to 30 mm calibre. – The total weight of all blocks of ERA is 2700 kg per one tank whilst the weight of blocks there on turret is 1 170 kg.

Does the Abrams have Era?

In March 2017, the Army announced that it would begin installing explosive reactive armor (ERA) packages, known as the Abrams Reactive Armor Tile (ARAT), on tanks in Europe, which will also be a feature on the new variants. ERA works by placing “tiles” filed with explosives over specific portions of a tank.

Does era protect against Apfsds?

Generally APFSDS rounds defeat ERA through sheer kinetic force. With some exceptions, ERA is not designed to protect against APFSDS rounds. Modern tank penetrators don’t need to carry any explosive to kill a tank.

How does ablative armor work?

Ablative armor is armor which prevents damage through the process of ablation, the removal of material from the surface of an object by vaporization, chipping, or other erosive processes.

What does reactive armour mean?

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. It is most effective in protecting against shaped charges and specially hardened kinetic energy penetrators.

What is explosive reactive armor?

Reactive Armours are a type of armour that reacts to the impact of a weapon to reduce the damage to the vehicle. It is very effective in protecting against shaped charges and specially hardened long rod penetrators. The brick is assymetric in its explosive interlayer, meaning that one end is thicker than the other.

How does the metal reactivity series work?

The metal reactivity series lists metals in order of their reactivity, from highest to lowest from top to bottom. A metal listed above another metal will replace that metal in a single replacement (single displacement) reaction.
