本文介绍了一种用于轨道炮发射的8兆焦耳底推式发射装置的设计。进行了广泛的内弹道学和飞行动力学分析。发射包的设计能够承受57千帕的峰值加速度和大量的横向载荷。横向载荷对于这种发射装置来说是至关重要的，以确保内部子弹接头的生存能力。尽管发射是通过底部推动的方法，但仍需要一个弹托来携带炮膛骑手。评估了弹托分离动力学和弹丸气动力系数，以确保成功飞行。该封装在32-MJ英国成功测试。电磁枪设施，柯克库布赖特，苏格兰，在7兆焦耳枪口能量。
This paper describes the design of an 8-MJ base-pushed launch package for railgun launch. Extensive interior ballistics and flight dynamic analyses were performed. The launch package was designed to withstand a peak acceleration of 57 k-gees, and a substantial amount of lateral load. The lateral load was of prime importance for this launch package to ensure survivability of subprojectile joints present inside. Even though the launch was by a base-push method, a sabot was necessary to carry the bore-riders. Sabot separation dynamics and projectile aerodynamic coefficients were evaluated to ensure a successful flight. The package was successfully tested at the 32-MJ U.K. EM Gun Facility, Kirkcudbright, Scotland, at 7-MJ muzzle energy.
