Fragmenting warhead

The SADARM system is thought to be unique because it uses a passive mm wave radiometric sensor in a high spin mode at low altitude — for the first time ever in a munition it uses a vortex ring parachute that maintains a constant spin rate and drop velocity, and is exceptionally stable and it delivers a long-standoff fragment warhead with armor-penetrating capability Ref Anon, ARRADCOM Voice (Oct 17,1977), 7... 

A fragmenting warhead is a special type of shaped charge or device that explosively forms projectiles. In such a device many EFPs of the shape of cones or cups are combined into one multi-projectile warhead (Fig. 7.9). Such devices which send out the projectiles in a cylindrical geometry are particularly suitable for targets in the air. 

The SM-2 s speed is Mach 3.5, and its range is up to 170 kilometers. The missile has radar and an infrared seeker for terminal guidance, and it has a blast fragmentation warhead. The SM-2 is being replaced by the SM-6, which has twice the range and better radar and is more agile so that it can better deal with the Russian sizzler cruise missile.

Sand Test or Sand Crushing Test(Sandprobe, in Ger) (Essai au sable, in Fr) (Pxueba de la arena, in Span). This test, devised by w .G.Snciiing in 1910 and studied extensively by C.G.Storm w. C.Cope(Rcf 1), is considered to measure the shatteringfdisruptive) power of an expl, called brisance. This characteristic is important because it determines the effectiveness with which an expl can fragment a shell, bomb casing, grenade or warhead of a rocket... 

The efficacy of Zr, Zr-Sn and of mischmetal incendiary fragments were comnared for the Zuni Mk 63 Mod 0 warhead (Ref 7). It was found in arena-type ignition tests that Zr was superior to mischmetal, but that Zr functioned approximately as well as its alloy, Zr-Sn. Wrought Zr was found not to function as well as compressed sponge, but was preferred because of its improved ease of fabrication...

The fragment velocity is largely dependent on the shape of the charge. For cylindrical charges (which are a good approximation for most bomb and missile (rocket) warheads) (Fig. 7.20) ...
