ANALYSIS OF THE 155 MM ERFB/BB PROJECTILE TRAJECTORY
Abstract
The article is focused on the external-ballistic analysis of the 155 mm artillery High-Explosive Extended-Range Full-Bore projectile with the Base Burn Unit (ERFB/BB), designed for the Slovak 155 mm Self-Propelled Gun Howitzer ZUZANA. The external-ballistic analysis of the characteristics of the 155 mm ERFB/BB shell is made for the Modified Point Mass Trajectory Model with additional terms for the Base Burn projectiles - Method 1 (MPMM+BB1) which is standardized in the STANAG 4355 agreement. The aim of this analysis is to determine all required data for the trajectory model mentioned above, specifically dimensional and mass properties, aerodynamic data, ballistic data and also the Base Burn Unit data. The results of the theoretical analysis are compared with the results of experimental firing tests.
