Abstract:

The design and material properties of rails and projectiles are critical to the success of the Navy railgun. This thesis addresses the design, fabrication, and testing of a scalable square bore electromagnetic railgun. This railgun is designed to permit series augmented operation, and incorporates disposable rail liners to facilitate investigating the suitability of various rail materials. A series of shots has demonstrated performance consistent with theoretical modeling, including significant performance enhancement as a result of both slotted rail geometry and augmentation over solid rail and un-augmented configurations. A capacitor based stored energy supply input of 35 kJ resulted in a measured velocity of 294 ms for an 11.4 gram projectile. Suggestions are provided for future power supply configurations, rail materials and surface treatments, and a variety of armature geometries.
