Railgun Solid Armature Scale Modeling
This paper describes a methodology for using two finite element (FE) codes, MAGTRPL and DYNA, to perform electromechanic, thermal, and structural modeling of railgun solid armatures. We analyze subscale armature experiments ...
The Diagnostic History of a New Electromagnetic Powder Deposition System
This paper describes the diagnostic tools used in the development of a new electromagnetic powder deposition system.
Electromagnetic Force, Jerk, and Electric Gun Projectile Design
As railgun projectiles have become more sophisticated, attention is being given to railgun produced electromagnetic forces that affect the mechanical loading of the projectile. The rate at which a launch package is accelerated ...
Iron Core Compulsators for Railgun Power Supplies
Recent development efforts on compulsator based railgun power supplies have been focused on lightweight, composite, self-excited machines. However, operating experience with the Iron-core (ferromagnetic) compulsator at the ...
Manufacturing and Testing of an Air-Core Compulsator Driven 0.60 Caliber Railgun System
A laboratory-based, small-caliber, electromagnetic launcher and compensated pulsed alternator power supply are being tested. The objective of the program is to develop a compact, lightweight testbed capable of accelerating ...
Fabrication of a Rotor for a Field Based, Self-Excited Compulsator Power Supply for a 9 MJ Railgun Demonstrator
Fabrication of a high-speed, self-excited air-core rotor for a field based compulsator is well under way. The compulsator is to be used as a power supply for firing 9 MJ projectiles from a skid mounted electromagnetic ...
Investigation of an Alternator Charged Pulse Forming Network with Flywheel Energy Storage
The authors present the conceptual design of a system to power an 18-shot, salvo fire 30 mm railgun. The performance of components was selected to be slightly beyond the state of the art but achievable in the near term. ...
Experimental Results from Solid Armature Tests at the Center for Electromechanics at the University of Texas at Austin
A number of solid armature tests have been conducted in a 90-mm gun facility over the past two years. Several different base push and mid-body drive armatures and projectile packages have been tested in the 50-m-deep ...
Coilgun Technology at The Center for Electromechanics, The University of Texas at Austin
The engineering trade-offs performed on a coilgun design are described. The concept used was that of a collapsing field accelerator. This concept was chosen because of its passive operation, and because it lent itself to ...
Testing of an Air Core Compulsator Driven 0.60 Caliber Railgun System
The Center for Electromechanics at The University of Texas at Austin (CEM-UT) is testing a laboratory based, small caliber, electromagnetic launcher and compensated pulsed alternator power supply. The objective of the ...
