轨道炮能将大量电能转化为弹丸的动能。2010年在海军研究办公室电磁轨道炮项目框架下进行的33-MJ枪口能量射击证明了这一点。从那时起，轨道炮一直是未来远程火炮系统的主要候选。在这种情况下，一枚重弹（几公斤）被加速到大约2.5公里/秒的初速。虽然这种高超音速炮弹的主要用途是轰炸数百公里外的目标，但它们也可用于对抗飞机攻击或其他直接射击场景。在这些情况下，大的初速度显著减少了撞击目标的时间。在本文中，我们研究了一个场景，其中未来的舰载轨道炮装置向目标提供与当代欧洲舰炮系统的爆炸弹相同的动能。同时，轨道炮在射程上优于当前的火炮系统。针对这种情况，导出了轨道炮系统参数的初稿。针对弹丸的飞行轨迹，利用德国航空航天中心（DLR）开发的工程工具，对不同发射角度下的弹道进行了仿真，并对气动加热进行了估算。这使得能够评估不同打击方案的可行性，以及确定该技术的限制。可以设想，这一基线设计可以用作讨论未来欧洲军舰可能的电气武器化的有用起点。
Railguns can convert large quantities of electrical energy into kinetic energy of the projectile. This was demonstrated by the 33-MJ muzzle energy shot performed in 2010 in the framework of the Office of Naval Research electromagnetic railgun program. Since then, railguns have been a prime candidate for the future long-range artillery systems. In this scenario, a heavy projectile (several kilograms) is accelerated to approximately 2.5-km/s muzzle velocity. While the primary interest for such a hypersonic projectile is the bombardment of targets hundreds of kilometers away, they can also be used to counter airplane attacks or in other direct fire scenarios. In these cases, the large initial velocity significantly reduces the time to impact the target. In this paper, we investigate a scenario, where a future shipboard railgun installation delivers the same kinetic energy to a target as the explosive round of a contemporary European ship artillery system. At the same time, the railgun outperforms the current artillery systems in range. For this scenario, a first draft for the parameters of a railgun system was derived. For the flight path of the projectile, trajectories for different launch angles were simulated and the aerothermodynamic heating was estimated using engineering tools developed within the German Aerospace Center (DLR). This enables the assessment of the feasibility of the different strike scenarios, as well as the identification of the limits of the technology. It is envisioned that this baseline design can be used as a helpful starting point for discussion of a possible electrical weaponization of the future European warships.
