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