An illustration of why sloped armour offers no weight benefit when protecting a certain frontal area. Comparing a vertical slab of armour (left) and a section of 45° sloped armour (right), the horizontal distance through the armour (black arrows) is the same, but the normal thickness of the sloped armour (green arrow) is less.
Typically, modern composite armour can provide the same amount of protection with much thinner and lighter construction than its protective equivalence in RHA. Likewise, the term is also used as a unit of measurement of penetration capability of armour-piercing weaponry , in terms of the millimetres of RHA that the weapon system can reliably ...
Traditionally, a warship's armor system was designed both separately from, and after, the design layout. The design and location of various component subsystems (propulsion, steering, fuel storage and management, communications, range-finding, etc.) were laid out and designed in a manner that presented the most efficient and economical utilization of the hull's displacement.
Ceramic armour normally even offers better protection for a given areal density when placed perpendicularly than when placed obliquely, because the cracking propagates along the surface normal of the plate. [10] Instead of rounded forms, the turrets of tanks using Chobham armour typically have a slab-sided appearance.
Any material that is harder than the rod itself may be used to produce sparks. Though the striker must have a sharp corner, sharp edge, or a knurled surface in order to produce sparks, carbon steel is not required. The idea that carbon steel is needed to produce sparks from a ferrocerium rod is an oft repeated myth.
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.
Ceramic armor is armor used by armored vehicles and in personal armor to resist projectile penetration through its high hardness and compressive strength. In its most basic form, it consists of two primary components: A ceramic layer on the outer surface, called the "strike face," backed up by a ductile fiber reinforced plastic composite or metal layer.
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 ...
