폭발에 의한 텅스텐 충격자의 분산 패턴 연구

초록

The dispersion pattern of near miss countermeasure has great effect on disablement of threatening projectile. In this study, the dispersion pattern of cylindrical tungsten impactors by an explosion in the near miss countermeasure was investigated by numerically. The mass and shape of the explosive were considered as the factors affecting the dispersion pattern. The explosives are set as 2 shape models; a parallel shape which has same upper, lower thicknesses and a tapered shape which has different upper, lower thicknesses. As a result of the simulations, the dispersed impactors formed a ring shaped pattern on a 2-dimensional plane in an arbitrary space and the fire net area increased with increasing explosive mass in case of identical explosive shapes and the tapered shape explosive formed the larger fire net area than the parallel shape explosive. Based on the analysis of fire net area and impactor dispertsion pattern of impactors in near miss countermeasure.
