The advanced Kontakt-5 explosive reactive armour on this T-90S is arranged in pairs of plates, giving the turret its prominent triangular profile.. An element of explosive reactive armour (ERA) is made of either a sheet or slab of high explosive sandwiched between two metal plates, or multiple "banana shaped" rods filled with high explosive which are referred to as shaped charges.
The suit's main feature is its "high-impact reactive armor", an electrically powered armor system that, when charged, absorbs two-thirds of the damage that Gordon would ordinarily suffer in Half-Life and 80% in Half-Life 2. [citation needed] A fully charged suit can survive several dozen hits from small arms and even one direct hit from an RPG.
The advanced Kontakt-5 explosive reactive armour on this Indian Army T-90S is arranged in pairs of plates with a triangular profile. Kontakt-5 is a type of second-generation [1] explosive reactive armour (ERA) originating in the Soviet Union. Due to the shortcomings of Kontakt-1, NII Stali developed a new type of reactive armor, Kontakt-5, so ...
Kontakt-1 (Russian: Контакт-1; GRAU indice: 4S20) is an explosive reactive armour (ERA) created in 1982 by Soviet NII Stali to protect tanks from shaped charges. The first tank with Kontakt-1 put into service was T-64BV in 1985. The system is still widely used by different countries within T-55, T-62, T-64, T-72, T-80 tank families among ...
The only example currently in widespread service is Russian Kontakt-5. Explosive reactive armour poses a threat to friendly troops near the vehicle. Non-explosive reactive armour is an advanced spaced armour which uses materials which change their geometry so as to increase protection under the stress of impact.
The Soviet T-64 was the first mass-produced tank with composite armour The Leclerc tank is equipped with NERA (Non-explosive reactive armour) [1] Depending on the operating state, the Leopard 2 has various extended armour elements such as bomb protection for the top, cage armour, extended mine protection (A6M) or additional armour in the form of composite armour MEXAS or AMAP Plasan SandCat ...
Second generation (comparable to third generation in other countries) of domestic Explosive reactive armour ERO-19 [citation needed] better than Kontakt-5 and comparable with Relikt is developed to protect against newer tandem charge HEAT warheads. Additional slat armor for protection against rocket-propelled grenades is also present. [19]
The best result was achieved by utilizing a 20 millimetres (0.79 in) thick MEXAS armour panel on top of a 7.3 millimetres (0.29 in) HHA plate fitted with a 10 millimetres (0.39 in) liner on the interior — a mass efficiency of 3.5; however the higher thickness decreased the thickness efficiency to 0.8 compared to the other tested armour layouts.
