Abstract

Focusing the dispersing direction of fragments with high-accuracy is one key issue in the design of advancedfocused fragmentation warhead for the application of aerial defence and antimissile. The similarity of mechanismbetween the focusing of geometrical optics and focusing of fragments is analysed in details, and it is proved thatthe driving direction of warhead fragment can be controlled according to the theory of geometrical optics. A newdesign model and method for Focused fragmentation warhead is obtained. The design is preliminary proved to beefficient by some tests, and it is found that 85 per cent of total fragment of the warhead can be focused within thedesigned focusing zone, which is an improvement to the 70 per cent obtained by other methods.
