“…This invention illustrates that the rods of these shapes are less at weigh than cylindrical rods, and can be packaged more efficiently in a KER warhead. These added rods increase the target damage by increasing the overall spray density at target impact [1,2].…”

The major technique of an air-defense warhead is to improve the damage after effect. Therefore, a new Kinetic Energy Rod (KER) warhead named profiled rod warhead is proposed in this paper. The detonation process is simulated by ANSYS/LS-DYNA, and the deployment velocity and initial flight attitude of rod are achieved. Rigid body dynamics equations of rod, which accounts for the influence of air resistance, are set up to predict the flight trajectory of long-distance. The results show that profiled rods are conducted to determine a higher penetrability compared with traditional cylindrical rods, and the profiled rods may provide a better penetration angle that still maintains a significant penetrability against projectiles when the rods move off long-distance range.

“…Gimbaled forwardfiring warhead(GFFW) is one kind of aimed warheads. The problems that fuze-warhead coordination and application on the missile about GFFW were discussed by doctor Lloyd in several books and papers [1,2,3] . Professor Zhuang Zhihong also researched the fuze-warhead coordination of GFFW [4] .…”

Gimbaled forward-firing warhead (GFFW) is one of the most efficient types for killing enhancement that exist today. This is because almost all the fragments of the warhead are deployed to the targets direction. Static explosion experiment was performed to investigate the spatial distribution of the spray pattern as well as its deployment velocity. The cone angle (θs) of fragments bundle at static conditions is 15°, and fragments in the mesial area is dense than that in the marginal area. The average velocity of the fragment in mesial area is 1712m/s, and that in marginal area is 1408m/s. In conjunction with deployment experiments, damage radius study is conducted with the basic criterion that one fragment must hit target payload at least. Damage radius at the dynamic conditions is 150m~165m, which is more farther than conventional uniform warhead.

The dispersion pattern of a near miss neutralizer has a great effect on the disablement of a threatening projectile. This study numerically investigated the dispersion pattern of cylindrical tungsten impactors by an explosion in the near miss neutralizer. The mass and shape of the explosive were considered as influencing factors on the dispersion pattern. The explosives were set using two shape models: a parallel shape with the same upper and lower thicknesses and a tapered shape with different upper and lower thicknesses. In the simulation results, the dispersed impactors formed a ring-shaped pattern on a two-dimensional plane in an arbitrary space. In addition, the fire net area increased with the explosive mass when the explosive shapes were identical. In particular, the tapered shape explosive formed a larger fire net area than the parallel shape explosive. Based on the analysis of the fire net area along with the dispersion density, both the explosive mass and shape representing the physical characteristics should be considered for controlling the dispersion pattern of impactors in a near miss neutralizer. § 이 논문은 2014 년도 대한기계학회 신뢰성부문 춘계학술대회
