AERODYNAMIC ANALYSIS OF PROJECTILE IN GUN SYSTEM FIRING PROCESS
During a gun firing, the flow around a projectile will be developing and changing. In particular, the flow around the projectile is disturbed significantly when the projectile overtakes the muzzle flow. Therefore, the shot ejection process has an important effect on the shot accuracy. After the projectile exits the muzzle, the projectile trajectory is disturbed by the muzzle flow. The interior ballistic process was coupled with the simulation of the process from the projectile engraving to the blowout phase, accounting for the moving projectile. The projectile velocity increased rapidly up to 0.8ms after muzzle exit; thereafter the projectile velocity increased slowly before reaching its maximum value.
