Fragmentation warhead is one of the main types of warheads, mainly by the role of high-energy explosives, the formation of a large number of high-speed fragments, using high-speed hitting the tungsten prefabricated fragments, the role of ignition and detonation damage targets, and can be used for anti-effectives (human, animal), no armor or light armored vehicles, aircraft, radar and missiles and other weapons and equipment. According to the generation of fragments channels, fragmentation warhead can be divided into natural, pre-control and pre-fragmented warhead three types.
Tungsten prefabricated fragments are natural under detonation. Tungsten alloy ball, the shell expansion, fracture broken of such warheads is characterized not only as a container shell to form another anti-elements, fragments the size of the uneven, irregular shape in the air fast decay in flight speed, so that the effective anti-personnel grenade is limited in scope. Usually, tungsten prefabricated fragments made from tungsten alloy ball.
Primary fragments are formed as a result of the shattering of the casing of conventional munitions. Tungsten alloy frefabricated fragments usually are small and travel initially at velocities of the order of thousands of feet per second. Secondary tungsten alloy prefabricated fragments are formed as a result of high blast pressures on structural components and items in close proximity to the explosion. These prefabricated fragments are somewhat larger than primary fragments and travel initially at velocities in the order of hundreds of feet per second. A hazardous prefabricated fragment is one having an impact energy of 58 ft-lb (79 joules) or greater. Tungsten alloy refabricated fragments forming a pre-processing will be the shape and quality of pre-designed steel ball, steel arrows, tungsten ball/tungsten sphere, tungsten prefabricated column fragments produced prefabricated sets of body fragments, and installed in the grenade projectile outer surface or inner surface. These prefabricated projectile fragmentation grenade explosion with the formation of fragments together constitute the natural fragmentation field, due to resistance of prefabricated fragments flying characteristic consistency, with tungsten alloy prefabricated fragments of the grenade will be set within the framework of the lethal effect of a relatively dense, full-bombs a greater degree of lethality increase.
