Design of a 20 GW, Self-Excited, Air-Core Compensated Pulsed Alternator Railgun Power Supply
A compact compensated pulsed alternator (compulsator) has been designed as a power supply for a 9 MJ kinetic energy railgun in conjunction with the Electromagnetic Gun Weapons System Program sponsored by the U.S. Army and ...
Fieldable Electromagnetic Gun Design
This paper describes the design of an electromagnetic (EM) gun capable of delivering launch packages at 2.5 km/s. The gun design methodology targets four areas where launcher technology must be advanced: efficiency, energy ...
Formation of Amorphous Metal By Hypervelocity Impact
The Center for Electromechanics at The University of Texas at Austin has investigated the use of an electromagnetic railgun accelerator for the deposition of non-crystalline metals. The two main objectives of the study ...
Alternator Power Conditioning for Launchers
A high-energy pulse-discharge is needed to drive an electromagnetic (EM) or an electro-thermal-chemical (ETC) launcher. Various pulse power generators have been examined and used. Capacitor-based power supplies are convenient ...
Effects of EM weapons requirements on the electric ship power system
The electric ship research effort at the University of Texas, Center for Electromechanics, is presently focusing on the development of a comprehensive model of ship power system. The model will allow the study of various ...
An electromagnetic gun power supply as a component of an electric ship power system
An electromagnetic gun provides a new component that must be integrated into the power system of an electric ship. An interesting topology for the power supply is a set of pulsed alternators with sufficient energy stored ...
Hypervelocity Plasma Sprayer Using Railgun Accelerators
This paper describes hypervelocity plasma spraying with railgun systems and describes the laboratory system designed and built at The University of Texas at Austin, which successfully validated the method of hypervelocity ...
Electric guns, theoretical and practical, have been around for many years in many forms. They have been slow to develop however because the competition, in the form of gas dynamic guns, has been formidable. To accelerate ...
AARADCOM/DARPA Compact Homopolar Generator
If electromagnetic (EM) rail guns are to be used to propel substantial projectiles, large amounts of energy must be delivered in a fast, high-current pulse. Homopolar generators (HPGs) store megajoules (MJ) of energy in ...
