This research is about characteristics of tank barrel inner flow according to the
barrel length and the pressure of ammunition when it is fired. By analyzing the flow
characteristics of the bore evacuator according to barrel length and ammunition
pressure before the ammunition design, it is possible to prevent the flareback
phenomenon that may occur during ammunition operation. Through bore evacuator flow
characteristic analysis by barrel length and ammunition pressure, we identified
additional design key factor about barrel and ammunition compatibility except speed,
accuracy, penetration performance and range when we developing new ammunition model.
As a test result, if longer the barrel length and lower the ammunition pressure, bore
evacuator operation time become slow. So the propellant gas will flow into the battle
vehicle with high possibility. Therefore, the correlation analysis method of the bore
evacuator flow characteristics based on barrel length and ammunition pressure is
considered as the main factor to improve the operational performance. So when we
design the new ammunition, the correlation analysis method will be used to determine
ammunition weight and select of the propellant pressure.
