Projectile Dispersion as Caused by Barrel Displacement in the 5-Inch Gun Probe System

摘要

The dispersion of theoretical ranges and firing azimuths due to lateral displacements in the barrel of the 5-inch gun probe system is analyzed. Computations were based on increments of tilt and azimuth displacements and for several nominal tilt angles. A nominal gross launch weight of 20 pounds and muzzle velocity of 5000 feet per second were used in the calculations for a 4000-foot MSL launch elevation. The theory is discussed, and graphs are presented detailing the theoretical effects of barrel displacements on ranges and firing azimuths. (Author)
