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 ...
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.
A single panel is 5.4 mm thick with a 260g explosive (85% hexogen) liner, surrounded by a 2.3 mm thick steel sheet. The container weighs 5.3 kg, and the full complement's weight varies from 1.2 to 2 tons depending on the number of containers used [2] [3] The explosive liner is highly insensitive so that it doesn't explode from bullets or ...
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 ...
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.
The typical Brinell Hardness range of MIL-A 12560 is 302-400 [2] The MIL-12560K standard actually specifies four classes of hardnesses. The softest class I rates as 260-310. The toughest Class 4 rates as 420-470. [3] (K is the revision number of the standard.) MIL-DTL-46177 is an older, now-replaced standard for a high hardness steel RHA. [4]
