Modeling of Micro-downburst accompanied with rain and analysis of its influence on artillery firing accuracy

Abstract The characteristics of wet micro burst are more complex, which will cause some deviation on the artillery range, side and other parameters, have a great influence shooting accuracy. Taking 155 mm explosive shell as research object, based vortex ring principle fluid mechanics, micro-downburst raindrop motion model was established, integrated into suitable for ballistic analysis calculation. combined with 6-DOF external artillery. Simulation effect different initial center induced velocity firing accuracy flat curved firing. experimental results show that long-range firing, range decreases increase induction center, seriously affects killing
