Optimization and Design of the Air Core Compulsator for the Cannon Caliber Electromagnetic Launcher System (CCEML)
MetadataShow full item record
The Center for Electromechanics at The University of Texas at Austin (CEM-UT) is currently in the manufacturing phase of a skid mounted, compulsator driven 30 mm (round-bore equivalent), rapid fire railgun system. The objective of the 30-month program is to develop a compact, lightweight test bed capable of launching three, five-round salvos of 185-g payloads to 1.85 km/s at a firing rate of 5 Hz. Per contractual requirement, the system is also fully compatible with the Amphibious Assault Vehicle (AAV). This paper describes the results of the optimization process used in determining the power supply requirements for the CCEML. The paper presents the performance specifications and design of the compulsator and critical power electronics resulting from the optimization process. The compulsator (CPA) is a four-pole, self-excited, air-core design which stores the energy for all three salvos inertially.
