Tungsten Alloy Spherical Fragments Piercing Performance

Air defense, anti-radiation, anti-surface and other types of warhead commonly used fragmentation warhead, mainly rely fragment kinetic-kill goal. Fragmentation can effectively kill the target and hit the target speed when fragmentation is closely related to the shape and quality. Fragments of spherical tungsten alloy (tungsten beads) due to the high density, attenuation coefficient, strong armor-piercing capability, become anti-aircraft, anti-radiation, the main choice of object surfaces and other types of anti-fragmentation warhead design.

Tungsten alloy spherical fragments due to its large density, speed, and ability to maintain strong piercing has gradually become the preferred elements warhead damage, so characteristic of research piercing tungsten alloy spherical fragments have a very important value. For the past fragments piercing questions, mostly concentrated in the conventional projectile velocity (500m / s ~ 1300m / s) hit Steel Fragments of the armor-piercing experiments and mechanism study of a single homogeneous steel target under the target conditions, and most of that: the same bomb target under the condition, completely through the thickness of the target plate hit the target with increasing speed must increase. For high projectile velocity (1300m / s ~ 3000m / s) piercing, pressure close to or exceed the material strength, impact body and the target material presented liquidity. In addition, with the increase of the target hit rate, tungsten alloy finite thickness of the initial invasion of impactor plate erosion and fragmentation phenomenon occurs, have a greater impact on the piercing process. Thus, the specific quality tungsten alloy fragments of penetration and steel target body there is a limit.
