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 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 ...
Non-explosive reactive armour (NxRA), also known as non-energetic reactive armor (NERA), is a type of vehicle armor used by modern main battle tanks and heavy infantry fighting vehicles. NERA advantages over explosive reactive armor (ERA) are its inexpensiveness, multi-hit capability, [ 1 ] and ease of integration onto armored vehicles due to ...
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.
Ceramic tiles have a multiple hit capability problem in that they cannot sustain successive impacts without quickly losing much of their protective value. [6] To minimise the effects of this the tiles are made as small as possible, but the matrix elements have a minimal practical thickness of about 25 mm (approximately one inch), and the ratio of coverage provided by tiles would become ...
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 ...
A key advantage of electric armour is its lighter weight. [3] Whereas ERA (explosive reacting armour) can add 10 to 20 tons of weight to a tank in explosives, electric armour could be effective with as little as a few tons of weight, [4] [5] [8] significantly reducing the load on the tank and allowing its weight capacity and engine power to be used elsewhere.
