Westinghouse Electric Corporation was the early leader in railgun technology in the 1980s and developed the 16 to 30 MJ stored energy homopolar-generator (HPG) powered system, EMACK, which provided the highest muzzle energy of any railgun from 1982 to 1988 during testing at Westinghouse Research and Development Center, Pittsburgh, PA, USA, and after installation at ARDEC, Picatinny, NJ, USA. Details of the design, components, and fabrication of EMACK are provided here, and results from the abbreviated initial testing are included. Many scientists, engineers and technical staff who worked on the project described here some 30 to 40+ years ago have by now mostly retired, moved on to other activities, or sadly, in several cases, are deceased. However, it would be remiss if their pioneering efforts were not recognized, and this article attempts to do that. Prospects for future energy storage and pulsed power developments using HPGs and more recent developments are also discussed.

西屋电气EMACK轨道炮


西屋电气公司是 20 世纪 80 年代轨道炮技术的早期领导者，开发了 16 至 30 MJ 储能单极发电机 (HPG) 动力系统 EMACK，该系统在 1982 年至 1988 年西屋电气测试期间提供了所有轨道炮中最高的炮口能量美国宾夕法尼亚州匹兹堡研发中心，以及在美国新泽西州皮卡汀尼 ARDEC 安装后。此处提供了 EMACK 的设计、组件和制造的详细信息，并包括简短的初始测试的结果。大约 30 至 40 多年前参与此处描述的项目的许多科学家、工程师和技术人员现在大多已经退休，转而从事其他活动，或者遗憾的是，在某些情况下已经去世。然而，如果他们的开创性努力没有得到认可，那就是失职，本文试图做到这一点。还讨论了使用 HPG 的未来储能和脉冲功率发展的前景以及最新的发展。
