Abstract

This paper presents the result of the study using numerical simulation software to determine the drag coefficient of the mortar ĐC100M-PST. Building a table of the drag coefficient corresponding to each different velocity value. The results of calculation are verified experimentally and ensure reliability. The results of studying help to design the mortar shape in the initial design phase to meet the requirements.
