This history helps explain an important factor in Ballistics and Stab armor testing, backing stiffness affects armor penetration resistance. The energy dissipation of the armor-tissue system is Energy = Force × Displacement when testing on backings that are softer and more deformable the total impact energy is absorbed at lower force.
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.
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 ...
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. In contemporary spacecraft, ablative plating is most frequently seen as an ablative heat shield for a vehicle that must enter atmosphere from orbit, such as ...
The vault has been compared being like "armor" or like a "tank", and the electronics within, like the spacecraft's "brain". [4] The power systems have been described as a "heart". [5] Without its protective shield, or radiation vault, Juno’s brain would get fried on the very first pass near Jupiter —
The major complication that must be improved for these types of armor is enhancing flexibility and reducing weight of armor without compromising protection from ballistic type impacts. [1] The primary benefit from nacre-inspired biological armor is its extreme ability to resist penetration through energy dissipation. [1]
Textile armor is tested for both penetration resistance by bullets and for the impact energy transmitted to the wearer. The "backface signature" or transmitted impact energy is measured by shooting armor mounted in front of a backing material, typically oil-based modelling clay. The clay is used at a controlled temperature and verified for ...
This mechanism, using a jet's own energy against it, has caused the effects of Chobham to be compared to those of reactive armour. [ citation needed ] This should not be confused with the effect used in non-explosive reactive armour : that of sandwiching an inert but soft elastic material such as rubber , between two armour plates.
