Muzzle Exit (Set Forward) Effects on Projectile Dynamics

Abstract

Set forward is a highly dynamic condition that occurs when a projectile exits the muzzle of a weapon. The levels of this acceleration, as well as the frequency, are dependent upon the projectile structural characteristics, length, and muzzle exit pressure. The set forward event can not, in general, be modeled using quasi static techniques. A dynamic analysis must be performed, especially for sensitive electronic components. Proper inspection of critical joints in the load path must be done with methods other than just using "go" and "no-go" thread gages.
