Study on Laws of Explosive Driven Behaviors of Aimed Warhead

The present numerical study is to investigate the explosive driven behaviors to the flight velocity and flight area of all the fragments of evolvable aimed warhead, and the propagating style of the detonation wave of the three-dimensional model. The results of numerical simulation demonstrate that the dual initiation that one eighth to the end of the axis has the best effect of the five initiation positions. Under the effect of the spherical explosive wave, the directional dispersion of the fragment of the three-dimensional model can be controlled well. The rationality of the numerical simulation was verified by the explosion experiments.
