Abstract

Abstract

In this work we examined and characterized the original velocity and flight velocity attenuation of the nonmetal fragments of a certain low-collateral-damage warhead in combination with its explosive power experiment.We obtained the fragments' original velocity including the shell configuration and material strength factors based on the conservation of energy, and derived the flight velocity attenuation regularity from the analysis of its fragment flight movement in the air and the modification of its resistance formula and the equivalent area of the spherical fragment.Our analytical result was confirmed by the experimental result, thus providing an analytical method for evaluating the fragment damage efficiency of this kind of warhead.
- low-collateral-damage warhead,
- nonmetal fragment,
- flight velocity,
- attenuation regularity
