Zusammenfassung:A 4.5-MJ capacitor-based, pulsed power supply has been installed at the U.S. Army Research Laboratory, Aberdeen Proving Ground, MD, for railgun operations. The system consists of 18 independent modules, each with an energy capacity of 250 kJ. Half of the modules were modified from their original condition to a pulse-forming inductance of 24 mH, while the remainder maintained their original 60-mH inductance. Another modification included a pneumatic-operated shorting system, added to enhance the safety of the system. Simulations were conducted for a variety of load conditions using a SPICE-based code. Predicted currents and velocities are in reasonable agreement with measured quantities. The complete system allows the electromagnetic launch of hypervelocity launch packages to a downrange distance of 4 km. --Original contains color plates: All DTIC reproductions will be in black and white.
