ANALYSIS OF LAUNCH INDUCED MOTION OF A HYBRID ELECTROMAGNETIC GAS GUN/

In recent years, great strides have been made regarding the identifica tion of the dominant loads that cause beam type vibrations of cannons during ballistic operation. These motions infringe upon shot accuracy because at projectile disengagement, the muzzle's kinematic state may compromise the projectile's intended flight path. This is particularly relevant to coil gun loading, which, unlike gas launch, applies the r ecoil load to the muzzle end of the barrel instead of the breech. This effectively places the barrel in a state of columnar compression duri ng the launch cycle that may exacerbate structural vibrations known as gun ''whip.''
