Influence of Muzzle Brakes Upon the Trajectory of Fin-Stabilized Projectiles.

Abstract

The dispersion of groups of fin-stabilized projectiles fired from high velocity cannon was measured for cases with and without a muzzle brake in place. The data clearly show degradation in precision due to the presence of the device. Diagnostic experiments and analyses were performed which indicate that the difficulties arise mainly due to gasdynamic loads within the muzzle device influencing both the projectile motion and sabot discard. Muzzle device design modifications are suggested to solve the problems. (Author)
