Electromagnetic Railgun with a Non-Explosive Magnetic Flux Compression Generator

Abstract

A lightweight, portable, electromagnetic railgun. The invention features a conventional railgun coupled to a magnetic flux compression generator (MCFG) section and an injector section. The conventional railgun has two parallel metallic rails (13,15) with a bullet (25) slidably positioned between them. The bullet is rapidly projected between the rails toward a chosen target when a current flows between the rails (and through the bullet). The MFCG section provides a source of high current to the rails. The MFCG section has a piston (730 which moves between two energized bars (51,53). A magnetic field is created by current flowing in a circuit through the piston, (73) the bars (51,53) and the bullet (25). The associated magnetic flux is rapidly compressed as the piston moves between the bars. Compression of the magnetic flux produces a large current pulse which is coupled to the rails (13,15) to propel the bullet (25). The injector section injects the piston (73) into the space between the bars (51,53) to begin the magnetic flux compression sequence.
