Abstract : Great strides have been made in recent years to identify 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 recoil load to the muzzle end of the barrel instead of the breech. This effectively places the barrel in a state of columnar compression during the launch cycle that may exacerbate structural vibrations known as gun 'whip.'
