Background
In modern wars, various kinetic and energy gathering bullets constitute a considerable destructive power for armored equipment. For example, various antitank missiles or rockets often employ hollow armor-breaking heads which when hit an armor explosion will generate high temperatures and high pressures in certain directions, the drug-shaped caps of which melt to form high-velocity metal jets, which can reach temperatures of thousands of degrees celsius. The pressure in penetrating the armor can reach millions of atmospheres, and the metal jet entering the vehicle, although reduced, can still directly kill the occupant, causing localized damage to the vehicle. More serious, the cracking of the oil tank and the hydraulic pipeline can be caused, so that the sprayed grease is mixed with air to form an oil-gas mixture with high explosion performance. If not suppressed in time, the explosion can be started within a few milliseconds, so that the whole armored equipment is damaged in a destructive manner, namely a secondary damage effect. The fire-extinguishing explosion-suppressing system is the most effective tool for dealing with the secondary damage effect at present.
