kunktator ::Možda je objašnjenje u fusnoti: "assumes energy directed and focused ..."?
Ko zna šta su oni računali? Ekvivalent ne po kinetičkoj energiji per se, već po tome koliko je predato po površini? Čudno.
Ali raketaševa računica je bez sumnje korektna. To je toliko energije i ne može biti više. Druga je pesma kako je raspoređeno, a to RAND-ov grafik ne precizira već se samo nagoveštava fusnotom. Malo brljiv rad.
Pa nije bas da je brljiv. Nego je dugacak, treba citati.
Dijagram je naslovljen "razorna snaga mase velike brzine kao funkcija brzine".
Znaci predstavlja razornu snagu, a koja je data u ekvivalentima kg TNT. Sto znaci, da bi se dobilo to razaranje potrebno je toliko kila TNT.
Citat:If the angle of impact produces a component of the velocity vector into the target that is
greater than the speed of sound in the target material, the crater will be hemispherical. For more glancing impacts, the crater will elongate, becoming more elliptical. Either way, the damage proceeds downward and outward from the point of impact. In contrast, the damage for an ordinary explosive detonated at the same point would proceed outward in all directions.
If the projectile is long and rodlike, on the other hand, the steady state phase dominates the effects. The crater is more cylindrical and its depth is proportional to the square root of the ratio of projectile density over target density. If the kinetic-energy weapon must penetrate shielding, e.g., a ship’s hull or a bunker, the depth to be penetrated determines the minimum projectile length, depending on the density of the shielding material. For example, a 1-m-long tungsten hypervelocity penetrator should be able to penetrate about 1.5 m of steel, almost 3 m of clay or stone, and 1 m of uranium. What penetrates through that depth (or less) of target will be a very hot mixture of target and penetrator material and any remaining penetrator length. The damage is done almost entirely in the direction of the impact, as with a shaped charge explosive, except for damage caused by secondary fires or explosions ignited by the impact.7
