A naval cannon was analyzed with the Little RASCAL gun dynamics program to predict shot exit conditions. There appeared to be a sharp manufacturing bend in the barrels vertical plane. The Little RASCAL program makes modeling many hypothetical cases easy. This report compares the projectile and barrel interacting forces with and without the effects of the sharp bend. More importantly, a small sinusoidal variation in the deviation of the barrel centerline preceding the sharp bend presents itself as a detrimental factor by amplifying the lateral forces.
