New Method for Axial Equal Explosive Field Intensity Control
Axial equal explosive field intensity is an important factor of damage effect. However, axial impulse acting on fragment is different from each other, because of different detonation modes, moving direction of detonation wave and rarefaction wave effect, and so on. Through the analysis on distribution of specific impulse acting on lateral wall for cylindrical charge and relationship between charge diameter and specific impulse acting on the end wall, this paper presents that producing equal explosive field intensity in axial by adjusting charge diameter, that is, adopting charge curve which is complementary to specific impulse curve. And the validity of this design has proved by numerical simulation and prototype test. The results indicate that axial specific impulse of charge surface is basically identical because of adopting suitable charge curve, which can form equal explosive field intensity effect on fragments, and fragment initial velocity increase due to axial energy gain.
