应注意，传统的等离子体电枢轨道炮由于电弧重燃而被限制在6-8 km/s的速度。作者认为，要实现等离子体电枢轨道炮的超高速潜能，必须消除重燃。他描述了两种基于已证明的技术的有前途的方法。近期的解决方案是某种形式的电路布置，其消除了重燃电弧中的电流流动。分段和分布式配置都值得进一步开发，但电气和机械复杂性的主要问题必须得到解决。从长远来看，先进陶瓷的开发加上降低电枢功率的措施显示出希望。需要特别注意以大于损伤阈值的速度注入射弹，并执行等离子体电枢以避免局部膛损伤。在控制下的再触发，唯一与等离子体有关的限制将是电枢等离子体上的粘性阻力。最近用氢等离子体电枢进行的实验表明，电枢速度超过30 km/s，因此电枢阻力在10-20 km/s的速度范围内似乎不是一个问题。>
It is noted that conventional plasma armature railguns are limited to velocities of 6-8 km/s by arc restrike. The author argues that to realize the hypervelocity potential of plasma armature railguns, restrike must be eliminated. He describes two promising approaches which are based on demonstrated technology. The near-term solution is some form of circuit arrangement which eliminates current flow in the restrike arc. Both segmented and distributed configurations merit further development, but major issues of electrical and mechanical complexity must be addressed. For the longer term, the development of advanced ceramics coupled with measures to reduce armature power shows promise. Special attention will be required to inject projectiles at a velocity greater than the damage threshold and to perform the plasma armatures to avoid local bore damage. With restrike under control, the only plasma-related limitation will be viscous drag on the armature plasma. Recent MIDI-2 experiments with a hydrogen plasma armature have demonstrated armature velocities in excess of 30 km/s, so armature drag does not appear to be an issue in the 10-20 km/s velocity regime. >
