Improved Design of Fragment Dispersion of Forward-Firing Warhead

Abstract

Because a uniform fragments field is needed for forward-firing warhead intercepting air targets, it is necessary to analyze quantitatively and improve fragments dispersion uniformity. The wave controller is added in the warhead to make fragments at marginal zone close to the dispersion center. The static explosion experiments are performed to obtain the fragments dispersion data before and after the warhead being improved. The results of data analysis indicate that the marginal fragments will close to the center after adding a suitable wave controller in the warhead. And at the same time the field density of fragments in the centre zone changes little. The fragments radial dispersion uniformity is much better than before. The effective fragments area is about 1.8 times larger than before, and the fragments quantity in effective fragments area increases 54.2%. But about 30% of total fragments are still not used effectively because of the sparse density, and the problem needs to be researched farther in the future.
